Between my love for basil and my obsession with classic Caprese flavors, I crafted this crustless quiche recipe back in 2020 as a fun mash-up of my favorite ingredients. But I’ve loved the concept so much that I’ve since made it in several other flavors, so you can choose what you want to put in yours. If you’re in a rush, a quiche without crust is your answer. Make it with me for a laid-back brunch with quicker prep time and less fuss!

Why You Need My Crustless Quiche Recipe

• Fluffy, custard-like texture – I love the light, creamy consistency. If you’ve made a frittata before, this crustless quiche is a lot like that, but there’s no need to partially cook on the stovetop.
• Customizable filling – My photos show a Caprese version, but I’ve experimented with 5 more filling ideas (plus a formula) to use any odds and ends in your fridge. See my variations below!
• Versatile, healthy dish – With just 6 simple ingredients (plus salt and pepper), my recipe for crustless quiche is perfect for breakfast , brunch, or even lunch . It’s also naturally gluten-free and packed with protein.

Ingredients & Substitutions

Here I explain the best ingredients for my easy crustless quiche recipe, what each one does in the recipe, and substitution options. For measurements, see the recipe card .

This crustless quiche is bursting with sweet tomatoes, fresh basil, and melty cheese, giving you that Caprese salad vibe in every bite, and I love that it doesn’t require pre-cooking anything. Here are the ingredients you’ll need for that, but below that I’ve got my formula to use any fillings you want, plus other flavor combos!

• Tomatoes – I used grape tomatoes this time, but have also made this crustless quiche with cherry tomatoes and even roasted tomatoes . I don’t recommend larger chopped tomatoes, as they can be too watery. You can toss in some sun-dried tomatoes , though.
• Fresh Basil – This is my favorite. You can also use other fresh herbs, like parsley or thyme.
• Garlic – Nothing beats fresh minced garlic, but if you are in a hurry, 2 teaspoons of jarred minced garlic will work.
• Eggs – Use room temperature eggs to get the smoothest custard texture.
• Milk Or Cream – Choose any kind you like! I used store-bought almond milk , but you could make my homemade almond milk , or use dairy milk, half and half, heavy cream, or coconut milk.
• Cheese – I chose fresh mozzarella cheese balls. Feel free to use shredded or cubed cheese instead.
• Sea Salt & Black Pepper

My Formula For Any Crustless Quiche

If you want to use different fillings, just use this formula to use anything you have on hand:

• 1 1/2 to 2 cups cooked meats or vegetables – or ones that don’t need cooking, like the tomatoes and basil I used here
• 8 large eggs
• 1/3 cup milk or cream – any kind
• 1 to 1 1/2 cups cheese – depending on how cheesy you want it
• 1/2 tsp sea salt – or less if using salty meats
• 1/4 tsp black pepper – or more to taste

How To Make Crustless Quiche

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. Make the filling. Mix tomatoes, basil, garlic, and mozzarella in a large bowl. If using other fillings like meats or veggies, cook them first. Then, transfer the mixture to a round pie pan (my go-to) or a square baking dish (the latter would make this a bit like a smaller egg casserole ).
2. Whisk the egg base. Wipe down the bowl and add the eggs, milk, salt, and pepper. Whisk together, then pour the egg mixture over filling ingredients.

1. Bake, adding more cheese near the end. Bake the crustless quiche until just a little jiggly, then top with more mozzarella and bake again until golden and completely set. Drain any excess tomato liquid, and garnish with more fresh basil. Sometimes I like a drizzle of balsamic glaze for something extra.

Filling Variations

I’m such a big fan of crustless quiche that I’ve tried several different fillings. To make these, just replace the tomatoes, basil, and fresh mozzarella with these — 1 1/2 to 2 cups of the meats and veggies (total) and 4-6 ounces of cheese.

• Broccoli Cheddar – Finely chopped sauteed broccoli + shredded cheddar cheese. One of my faves!
• Ham & Swiss – Throw in diced ham and shredded or cubed Swiss cheese. I like a ham and cheese crustless quiche almost just as much as the Caprese version, because it’s another option with no pre-cooking.
• Zucchini – Use sauteed zucchini and onions, fresh dill or chives, and any cheese you like. You can also use my crustless zucchini quiche recipe instead.
• Spinach – You can use thawed and drained frozen spinach or sauteed spinach , and I liked this one with a blend of mozzarella and feta cheese. I also have a different recipe for crustless spinach quiche here .
• Quiche Lorraine – My fave French-inspired version with bacon and cheese! This is one of the most popular recipes in my Easy Keto Cookbook .

My Recipe Tips

• Pre-cook your fillings if needed. One of the reasons this tomato basil version is my best crustless quiche recipe is because you don’t have to pre-cook anything. But if you use vegetables that need to be tender, or any meats, make sure to cook them first.
• Pat fresh mozzarella dry if needed. If it’s very wet and you don’t dry it, it can make your quiche watery.
• Forgot to let your eggs come to room temp? You can place them in a bowl of warm water to get there quickly. This will improve the texture of the final dish.
• Be careful not to overcook. The baking time can vary, and will depend on the shape and material of the pan you use. If you bake the crustless quiche for too long, it can get rubbery. It’s time to add the cheese toward the end when the quiche is almost set but still jiggly, and the quiche is done when it’s fully set. I check by inserting a knife into the center — it should come out clean.
• Prefer to make a crust? You can use any kind you like, as long as you pre-bake it. My fave is almond flour pie crust , but I also have a coconut flour pie crust . You’ll need to cover the crust edges with foil or a pie crust shield to prevent burning it. I’d also recommend reducing the filling to 5 eggs, 1 1/2 cups of fillings, and 1 cup of cheese, like my quiche recipe here .

Storage & Meal Prep

• Store: Place any leftover quiche in an airtight container and store in the fridge for up to 3-4 days.
• Meal prep: You can assemble my easy crustless quiche recipe up to 1 day ahead and bake it fresh, which is my preferred way to do it. You can also bake it and store for a few days, then simply reheat.
• Reheat: The best way to reheat is in the oven, as the microwave can be more drying.
• Freeze: You can freeze any of my crustless quiche recipes (either the original here or the variations above) for up to 3 months. Just wrap tightly in plastic wrap followed by a layer of aluminum foil. Thaw in the refrigerator overnight before reheating.

Serving Ideas

You can definitely serve crustless quiche all on its own, but if you’re planning a brunch spread, serve it with:

• Breakfast Meats – Pop some bacon in the oven , or turkey bacon for a lighter option.
• Sweet Breads – I love this crustless quiche with my healthy zucchini muffins or banana bread for a sweet and savory combo.
• Pancakes – Try my almond flour pancakes or coconut flour pancakes for fluffy, healthy options.
• Salads – My fave brunch salads lately are antipasto salad , radish salad , or cucumber tomato salad .

My Favorite Pans For This Recipe

I usually use my round pie dish to give it a classic look. But when I want to bring this crustless quiche somewhere, I like this square dish that comes with a lid.

Crustless Quiche

Gratitude Moment

We went to my parents’ house for dinner this week. I’m grateful to have this time with them while we visit in the summers, though I wish we had more of it.

I discovered that their garden cherry tomatoes are starting to ripen, so I’m hoping they might have enough or me to make this crustless quiche before we leave Minnesota.

I’ve heard that tomatoes are some of the easiest veggies to grow, so I need to try it one of these days. So far the only plants I can keep alive are a cactus and my basil plant, ha.

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.

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.
• 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.

Foods To Avoid On Keto

• White flour & sugar
• Rice & grains – Such as barley, wheat, and corn.
• Milk & yogurt – Such as fruit on the bottom yogurt, sweetened Greek yogurt, and all milk.
• Cereal
• Processed food – Such as granola bars, candy
• Most fruit – Such as apples, bananas, and grapes
• Hydrogenated fats – Such as vegetable oil, soybean oil, and margarine
• Sweetened beverages & condiments – Such as soda, ketchup, and sweet dressings
• Starchy veggies – Such as peas, carrots, and beets.
• Potatoes – Such as sweet potatoes and white potatoes.

That’s the short keto diet cheat sheet version of all the keto food categories, but I recommend downloading the full Keto Cheat Sheet System. It includes a super detailed printable keto food list with over 100 items, including 2 color-coded pages with net carb counts, along with 6 more pages of keto cheat sheets:

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:

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.
