This chicken cordon bleu casserole is my easier, healthier spin on the Swiss dish I grew up eating. I took all the comforting flavors of the classic — chicken, ham, and melty cheese — and turned them into a satisfying meal that’s a breeze to make. This is one of my oldest chicken casseroles (from 2017), and I’ve tweaked it over the years to add a hidden veggie and adjust the amount of sauce, but I still keep coming back to it. Make it with me for a healthy dinner when you’re craving comfort food!

Why You Need My Chicken Cordon Bleu Casserole Recipe

Maya in the kitchen. - 1
  • An easier way to make chicken cordon bleu – Forget pounding and rolling individual chicken pieces! My chicken cordon bleu casserole has tender chicken, savory ham, creamy Dijon sauce (a little like my recent chicken broccoli casserole ), and melty Swiss cheese, but without the breading and hassle. It’s not traditional, but it’s the same comforting vibe with less work!
  • Complete dinner in one dish – You know I’m always making these. 😉 This casserole is packed with protein, veggies, and cheese, so it’s a wonderful meal all by itself.
  • Simple, natural ingredients – Many recipes are heavy with pasta or mystery cream-of soups, but mine is low carb, gluten-free, and even sneaks in a hidden veggie. I love this dish so much, I included it in my second cookbook !

Ingredients & Substitutions

Here I explain the best ingredients for my recipe for chicken cordon bleu casserole, what each one does, and substitution options. For measurements, see the recipe card .

  • Chicken – You’ll need it pre-cooked for this recipe. I used my Instant Pot shredded chicken , but you can also grab a rotisserie chicken, bake chicken breast , or use any leftover chicken you’ve got. Cooked chicken thighs work as well if you prefer dark meat.
  • Ham – I usually just chop deli ham. Leftover glazed ham is such a treat if you have it!
  • Swiss Cheese – This is the classic cheese for chicken cordon bleu, but Gruyere, mozzarella, or provolone would also pair well with these flavors. I use shredded cheese, but you can chop slices to mix in and melt full ones on top.
  • Cauliflower – Roasted cauliflower is my secret veggie of choice for this chicken cordon bleu casserole, because its flavor is neutral and doesn’t overpower the main components. You’ll also need oil (I use avocado oil , but olive oil is great too) for roasting it.
  • Creamy Ingredients – Heavy cream and sour cream! Don’t use milk (it’s too runny), but it’s fine to use full-fat canned coconut milk and Greek yogurt as swaps if you like.
  • Dijon Mustard – Although you can use yellow mustard, I prefer the milder, less acidic Dijon here. I thought 2 tablespoons was the perfect amount, but you can taste the sauce and adjust to your liking.
  • Garlic – Fresh minced garlic is ideal, but 2 teaspoons jarred garlic or 1/2 teaspoon of garlic powder works if you’re short on time.
  • Topping – Optional, if you like a little crunch! I used pork rinds this time, but also love this casserole with gluten-free panko bread crumbs.
  • Sea Salt & Black Pepper

How To Make Chicken Cordon Bleu Casserole

I have step-by-step photos here to help you visualize the recipe. For full instructions with amounts and temperatures, see the recipe card .

  1. Season the cauliflower. Toss it with oil, sea salt, and pepper in a large bowl.
  2. Roast until browned. Spread it out on a baking sheet ( this one is my favorite and it’s made in the USA) and let your oven do its thing.

  1. Mix the sauce. In a large bowl, whisk together the heavy cream, sour cream, Dijon mustard, garlic, and some shredded cheese, until smooth.
  2. Add the shredded chicken, ham, and roasted cauliflower. Fold them in gently, so your cauliflower doesn’t get mushy.

  1. Assemble the casserole. Scoop the mixture into a baking dish — I use and love this casserole dish that looks great going straight to the table. Sprinkle on more cheese, and top with crushed pork rinds or breadcrumbs (if you’re using them).
  2. Bake until golden brown. Pop the chicken cordon bleu casserole in the oven and bake until the cheese is melted, golden, and bubbly. Add a sprinkle of chives or parsley on top if you like!

My Recipe Tips

  • I repeat, your chicken must be precooked. The baking time in my chicken cordon bleu casserole recipe is not long enough to cook it, and it’ll cook unevenly if you just increase the time. I have lots of options above for different ways to cook your chicken or use leftovers.
  • Shredded chicken tastes a bit better than diced in this recipe. You can use either, but the sauce seeps into the shredded kind and keeps it more juicy.
  • If your chicken is unsalted, you might want to add a bit more salt to the sauce. Just taste before baking and adjust to your liking.
  • How to avoid a watery casserole: Make sure to roast your cauliflower for long enough, as it will release water into your casserole if it’s undercooked. Also, if your sour cream is watery, drain any liquid before adding it.
  • If your chicken and ham are cold, bake for longer. Mine sat out at room temp for a bit and then the hot cauliflower warmed them a bit, so the casserole heated up pretty fast. Just bake until it’s hot!
  • Don’t want the cauliflower? You can make my chicken cordon bleu casserole without it and just reduce the amount of sauce a bit.
  • Want to make it more hearty? I’ve also made this with roasted potatoes when I wanted it extra hearty.
  • Want to pack in more greens? Feel free to roast other veggies for this recipe! Sometimes I replace half the cauliflower with roasted broccoli , or add a cup of sautéed spinach . They’re not conventional, but I thought they worked so well with these flavors when I tried this!
  • Broil for a golden top. If you love a bubbly, browned topping, broil the casserole for a couple of minutes after baking. Just keep an eye on it so it doesn’t burn!

Serving Ideas

Like I said, I love that this chicken cordon bleu casserole is a meal all by itself, so I don’t usually serve it with anything else! But it’s also very rich and hearty, so if you want something light to balance it out, I recommend a side of roasted asparagus or one of my light salad recipes , like cucumber tomato salad or arugula salad .

Maya’s Recipe Notes

Serving size: 1 cup, or 1/12 of entire casserole

  • Tips: Check out my recipe tips above to help you get the right flavor and texture with a golden brown top, avoid a watery casserole, and variations if you don’t want to use cauliflower.
  • Store: Keep leftovers in an airtight container in the refrigerator for up to 3-4 days.
  • Meal prep: You can cook the chicken and roast the cauliflower ahead, but I prefer to assemble the entire casserole in advance. I do recommend baking it fresh if you’re using the optional pork rinds or bread crumbs, because they lose their crunch when reheating.
  • Reheat: Warm it up in the oven at 350 degrees F, or pop individual servings in the microwave.
  • Freeze: You can freeze my chicken cordon bleu casserole before or after baking, but I prefer before (see my note in the meal prep section above about the topping). Either way, it stores pretty well in the freezer for up to 3 months, although the texture of the sauce is a bit different. Thaw in the fridge before reheating.

The Basic Keto Meal Formula

Eating keto doesn’t have to be complicated! While there are plenty of delicious easy keto recipes to choose from, you don’t even have to cook from a recipe to get started.

Simply follow the keto cheat sheet formula of protein + veggie + fat for your meals.

Be sure to choose a moderate amount of protein, only low carb vegetables (mostly ones that grow above ground), and generous fat to attain an optimal macro ratio. That’s approximately 60-75% of calories from fat, 20-25% protein, and 5-10% from carbohydrates. The table below will give you ideas for what to choose.

Pick A ProteinPick A VeggieAdd Fat
Beef Chicken Pork Eggs Lamb Turkey Fish Shellfish Protein powder VenisonCauliflower Broccoli Zucchini Leafy Greens Cucumbers Brussels Sprouts Cabbage Asparagus Radishes Bell Peppers Jicama CeleryButter Avocado Oil Cheese Bacon Avocado Lard Ghee Mayo Nuts MCT Oil

Understanding Macros

Macros are macronutrients for short. They include fat, protein, and carbohydrates.

You can calculate your own macros using the macro calculator , but the macro keto cheat sheet below will explain how to look at macros when following a keto lifestyle.

Carbs Are A Limit.

Keeping carbs low is what gets you into ketosis and keeps you there. Ketosis means that you’re using fat as your primary energy source instead of sugar, and requires keeping carbs very low.

A good starting point is 20-25 grams net carbs per day, but you can experiment after a few weeks to see if your body stays in ketosis at higher levels. People who are very active may be able to do more and stay in ketosis, up to around 50 grams per day.

“Carbs are a limit” means that you set a limit for how many carbs to eat per day and don’t exceed it. You don’t have to hit that limit, so if you’re under that’s okay, just don’t go over. Ideally most of your carbs would come from low carb vegetables, and if you’re eating enough veggies, you’ll usually get close to the limit naturally.

A common misconception is that reaching ketosis requires a certain macro ratio, but it’s really only restricting your carb intake that gets you there [ * ]. In the absence of sufficient carbs to use as energy, the body will switch to using fat as fuel. This is called the metabolic state of ketosis.

Protein Is A Goal.

Protein is made up of amino acids, the building blocks of all our cells. It’s a crucial for keeping our muscles strong and for many cellular functions [ * ].

“Protein is a goal” means that you always want to eat enough protein to reach the goal each day, but not exceed it too much. You want enough for your needs, but excess protein can trigger gluconeogenesis, which is protein being converted to sugar [ * ] and can kick you out of ketosis.

Fat Is A Lever.

Fat is the primary macronutrient in a keto lifestyle, because being in ketosis means that fat is your primary fuel source. Fat as a fuel source will come from your food, and if you are losing weight, from your body.

A big advantage of a keto lifestyle is the high fat intake. It keeps you full and satisfied, making it easier to stick to, and using it as the primary fuel source makes it easier on your body to burn body fat, with a lower chance of breaking down your muscle (provided you get enough protein).

Aside from reaching your protein goal and limiting your carbs, the remainder of your calories on a keto diet comes from fat.

Don’t fear fat – it’s your main energy source on keto, and getting enough of it trains your body to use fat for fuel instead of sugar. That means that as long as you are not overdoing your overall calorie intake, you’ll efficiently burn your body fat for fuel as well.

“Fat is a lever” means that you can increase or decrease your fat intake depending on your goals and hunger levels. Increase it (along with exercise) to gain muscle, or decrease it to lose weight.

Keto Food Swaps

One of my favorite challenges is creating recipes, or just discovering, keto food swaps. These are delicious keto replacements for traditionally high-carb or high-sugar foods.

So, I created this keto diet cheat sheet with all the swaps in one place! I also have more keto food swaps in my Easy Keto Cookbook .

Keto Food List

When looking for a keto cheat sheet printable, the most-requested information is a keto food list.

The great thing is that keto doesn’t have to feel restrictive. It’s incredibly satisfying and there’s such a wide variety of foods you can eat!

Keto foods to eat and avoid summary - 19

Foods To Eat On Keto

  • Leafy greens – Such as spinach, chard, and lettuce.
  • Above-ground veggies – Such as peppers, zucchini, and cauliflower.
  • Full-fat cream & cheese – Such as heavy cream, sour cream, and full-fat hard cheeses.
  • Natural meats – Such as beef, lamb, and pork.
  • Berries – Such as raspberries, blackberries, and strawberries.
  • Avocados
  • Unsweetened nut milks – Such as almond milk and coconut milk.
  • Almond flour and coconut flour
  • Eggs
  • Healthy fats – Such as coconut oil, avocado oil, olive oil and butter.

Electrolyte Basics

Getting enough electrolytes is crucial for anyone, but especially so on a keto diet. The reason is that ketosis has a diuretic effect, which increases excretion of water and electrolytes, especially sodium [ * ]. This is often the cause of the keto flu.

For more details on electrolytes and avoiding keto flu, check out the full keto flu guide here .

The important thing to know about electrolytes is that replenishing them will keep keto flu away and keep your body functioning well. I always recommend an electrolyte drink and whole food sources of anything your body needs before resorting to supplements, so I made a list of what to eat to get each of the 3 major electrolytes – sodium, magnesium and potassium.

Here’s your keto diet cheat sheet for getting electrolytes from food:

SodiumMagnesiumPotassium
Bone broth Boullion cubes Bacon Salted nuts PicklesSeaweed Seeds Nuts Avocado Leafy greensPotassium chloride Avocado Bone broth Spinach Broccoli Mushrooms Beef Pork

Keto Diet Types

People follow a keto lifestyle for different reasons. Some do it just to lose weight, others are after better overall health, increased energy, and reduced inflammation.

Strictly speaking, the defining factor of a keto diet is the metabolic state of ketosis, which is achieved by restricting carbs. However, many people (myself included) also reduce or eliminate processed, inflammatory, or low-nutrient foods.

Below is your keto cheat sheet summary of the different ways that people follow keto. You choose what works best for your goals and lifestyle!

  • Strict Keto – Up to 20-30g net carbs daily, count all calories and macros, and eat clean, unprocessed foods.
  • Lazy Keto – Up to 20-30g net carbs daily, and track only net carbs OR eat keto foods without tracking.
  • Dirty Keto – Up to 20-30g net carbs daily, with “if it fits your macros” approach including processed foods.
  • Low Carb – Up to 50-100g net carbs daily, less strict.

This chicken cordon bleu casserole is my easier, healthier spin on the Swiss dish I grew up eating. I took all the comforting flavors of the classic — chicken, ham, and melty cheese — and turned them into a satisfying meal that’s a breeze to make. This is one of my oldest chicken casseroles (from 2017), and I’ve tweaked it over the years to add a hidden veggie and adjust the amount of sauce, but I still keep coming back to it. Make it with me for a healthy dinner when you’re craving comfort food!

Ingredients & Substitutions

Here I explain the best ingredients for my recipe for chicken cordon bleu casserole, what each one does, and substitution options. For measurements, see the recipe card .

  • Chicken – You’ll need it pre-cooked for this recipe. I used my Instant Pot shredded chicken , but you can also grab a rotisserie chicken, bake chicken breast , or use any leftover chicken you’ve got. Cooked chicken thighs work as well if you prefer dark meat.
  • Ham – I usually just chop deli ham. Leftover glazed ham is such a treat if you have it!
  • Swiss Cheese – This is the classic cheese for chicken cordon bleu, but Gruyere, mozzarella, or provolone would also pair well with these flavors. I use shredded cheese, but you can chop slices to mix in and melt full ones on top.
  • Cauliflower – Roasted cauliflower is my secret veggie of choice for this chicken cordon bleu casserole, because its flavor is neutral and doesn’t overpower the main components. You’ll also need oil (I use avocado oil , but olive oil is great too) for roasting it.
  • Creamy Ingredients – Heavy cream and sour cream! Don’t use milk (it’s too runny), but it’s fine to use full-fat canned coconut milk and Greek yogurt as swaps if you like.
  • Dijon Mustard – Although you can use yellow mustard, I prefer the milder, less acidic Dijon here. I thought 2 tablespoons was the perfect amount, but you can taste the sauce and adjust to your liking.
  • Garlic – Fresh minced garlic is ideal, but 2 teaspoons jarred garlic or 1/2 teaspoon of garlic powder works if you’re short on time.
  • Topping – Optional, if you like a little crunch! I used pork rinds this time, but also love this casserole with gluten-free panko bread crumbs.
  • Sea Salt & Black Pepper

How To Make Chicken Cordon Bleu Casserole

I have step-by-step photos here to help you visualize the recipe. For full instructions with amounts and temperatures, see the recipe card .

  1. Season the cauliflower. Toss it with oil, sea salt, and pepper in a large bowl.
  2. Roast until browned. Spread it out on a baking sheet ( this one is my favorite and it’s made in the USA) and let your oven do its thing.

  1. Mix the sauce. In a large bowl, whisk together the heavy cream, sour cream, Dijon mustard, garlic, and some shredded cheese, until smooth.
  2. Add the shredded chicken, ham, and roasted cauliflower. Fold them in gently, so your cauliflower doesn’t get mushy.

  1. Assemble the casserole. Scoop the mixture into a baking dish — I use and love this casserole dish that looks great going straight to the table. Sprinkle on more cheese, and top with crushed pork rinds or breadcrumbs (if you’re using them).
  2. Bake until golden brown. Pop the chicken cordon bleu casserole in the oven and bake until the cheese is melted, golden, and bubbly. Add a sprinkle of chives or parsley on top if you like!

My Recipe Tips

  • I repeat, your chicken must be precooked. The baking time in my chicken cordon bleu casserole recipe is not long enough to cook it, and it’ll cook unevenly if you just increase the time. I have lots of options above for different ways to cook your chicken or use leftovers.
  • Shredded chicken tastes a bit better than diced in this recipe. You can use either, but the sauce seeps into the shredded kind and keeps it more juicy.
  • If your chicken is unsalted, you might want to add a bit more salt to the sauce. Just taste before baking and adjust to your liking.
  • How to avoid a watery casserole: Make sure to roast your cauliflower for long enough, as it will release water into your casserole if it’s undercooked. Also, if your sour cream is watery, drain any liquid before adding it.
  • If your chicken and ham are cold, bake for longer. Mine sat out at room temp for a bit and then the hot cauliflower warmed them a bit, so the casserole heated up pretty fast. Just bake until it’s hot!
  • Don’t want the cauliflower? You can make my chicken cordon bleu casserole without it and just reduce the amount of sauce a bit.
  • Want to make it more hearty? I’ve also made this with roasted potatoes when I wanted it extra hearty.
  • Want to pack in more greens? Feel free to roast other veggies for this recipe! Sometimes I replace half the cauliflower with roasted broccoli , or add a cup of sautéed spinach . They’re not conventional, but I thought they worked so well with these flavors when I tried this!
  • Broil for a golden top. If you love a bubbly, browned topping, broil the casserole for a couple of minutes after baking. Just keep an eye on it so it doesn’t burn!

Serving Ideas

Like I said, I love that this chicken cordon bleu casserole is a meal all by itself, so I don’t usually serve it with anything else! But it’s also very rich and hearty, so if you want something light to balance it out, I recommend a side of roasted asparagus or one of my light salad recipes , like cucumber tomato salad or arugula salad .

Maya’s Recipe Notes

Serving size: 1 cup, or 1/12 of entire casserole

  • Tips: Check out my recipe tips above to help you get the right flavor and texture with a golden brown top, avoid a watery casserole, and variations if you don’t want to use cauliflower.
  • Store: Keep leftovers in an airtight container in the refrigerator for up to 3-4 days.
  • Meal prep: You can cook the chicken and roast the cauliflower ahead, but I prefer to assemble the entire casserole in advance. I do recommend baking it fresh if you’re using the optional pork rinds or bread crumbs, because they lose their crunch when reheating.
  • Reheat: Warm it up in the oven at 350 degrees F, or pop individual servings in the microwave.
  • Freeze: You can freeze my chicken cordon bleu casserole before or after baking, but I prefer before (see my note in the meal prep section above about the topping). Either way, it stores pretty well in the freezer for up to 3 months, although the texture of the sauce is a bit different. Thaw in the fridge before reheating.
