This reuben casserole is one of my favorite ways to enjoy corned beef. You can get your beef right from the deli, or make my pressure cooker corned beef and use the leftovers in this casserole. And since there’s no bread involved, it’s naturally low carb and gluten-free. With all the sweet, sour, and umami flavor in here, plus melty swiss cheese, you won’t give it a second thought — I know I don’t. Make this easy reuben casserole recipe with me for a comforting, healthy dinner tonight!
How To Make Reuben Casserole
- Roast cauliflower. Toss cauliflower with oil , salt , and pepper and roast in the oven, until browned. See my tips in my roasted cauliflower post to get perfectly tender, golden brown florets.
- Assemble. Spread the roasted cauliflower in the bottom of a 9×13 inch baking dish . Top with sauerkraut , my sugar-free Thousand Island dressing , corned beef, and then swiss cheese.
- Bake. Pop your reuben casserole in the oven, until it’s hot and the cheesy is melty. (I love that melty cheese so much!)
Common Questions
- What is reuben casserole? My reuben casserole recipe takes all of the flavor of reuben sandwiches and puts it into a super simple casserole form. I make it with roasted cauliflower , corned beef, sauerkraut , sugar-free Thousand Island dressing , and melty swiss cheese.
- Is reuben casserole keto? It depends on the casserole recipe and what the ingredients are! Mine uses cauliflower instead of typical casserole carbs (like rice or potatoes), so each meal-sized serving has just 4.5 grams net carbs .
- Is it gluten-free? Yes, while most reubens are made in sandwich form with bread, this one uses cauliflower, which makes it a great gluten-free meal. Sometimes I even serve my keto bread on the side and still keep it gluten-free.
- Can I use store-bought Thousand Island dressing? Yes, you can. They are not usually low carb though, so I highly recommend making my Thousand Island dressing . It’s super easy, has the best flavor, and no added sugar.

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 Protein | Pick A Veggie | Add Fat |
|---|---|---|
| Beef Chicken Pork Eggs Lamb Turkey Fish Shellfish Protein powder Venison | Cauliflower Broccoli Zucchini Leafy Greens Cucumbers Brussels Sprouts Cabbage Asparagus Radishes Bell Peppers Jicama Celery | Butter 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!
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.

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:
| Sodium | Magnesium | Potassium |
|---|---|---|
| Bone broth Boullion cubes Bacon Salted nuts Pickles | Seaweed Seeds Nuts Avocado Leafy greens | Potassium 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.
