The beauty of quiche is that it’s an appropriate dish for any occasion, but the crust is typically made with flour. This flourless egg white spinach quiche is baked frittata style with cottage cheese, so it’s packed with protein, low in carbs, and full of flavor!

This isn’t your average crustless quiche. You’ll bake egg whites, creamy cheddar, spinach, onion, spices, and cottage cheese into a fluffy frittata sure to impress everyone around your table.

The secret to the success of this crustless spinach quiche is cottage cheese. It elevates the savory flavors and creates an irresistibly rich and velvety texture. Even the kids dive into this healthy crustless quiche. I may be biased, but this keto quiche recipe is THE best!

Why You’ll Love This Recipe

  • It’s a high-protein quiche made with egg whites, cheddar, and cottage cheese.
  • This low-carb spinach quiche is as delicious as the classic.
  • Perfect for weekend breakfasts, holiday brunches, or whenever you’re craving quiche.
  • Gluten-free and no flour!
  • Plenty of room to customize.

Ingredients You’ll Need

  • Extra virgin olive oil – to sauté the veggies.
  • Onion – Yellow onion or sweet onion for a deep, savory flavor.
  • Frozen chopped spinach – Thawed and drained well. The spinach should be as dry as possible before adding it in. I don’t recommend using fresh spinach here.
  • Cheddar cheese – Grated fresh from a block. Freshly grated cheese gives the quiche a creamier texture than the bagged stuff, but use what works. Monterey Jack is another tasty option.
  • Eggs – For a keto egg white quiche, you’ll need 8 large egg whites (or 1½ cups carton liquid egg whites) plus 1 whole egg. Feel free to adjust the egg white to full egg ratio or make it with all whole eggs.
  • Cottage cheese – Regular cottage cheese or low fat cottage cheese. Up to you!
  • Spices & seasonings – Cayenne red pepper, black pepper, salt, and a pinch of nutmeg for a kick of warm flavors.

How To Make Cottage Cheese Quiche with Spinach

Step 1: Prepare for baking. Preheat your oven to 375F and coat a 9″ pie pan with cooking spray. Set aside.

Step 2: Cook onion and spinach. Heat oil in a skillet over medium-high heat. Add onion and cook until soft. Then, add the spinach and cook until the leaves are wilted and dry. Set the skillet aside.

Step 3: Whisk egg batter. In a large bowl, whisk the egg, egg whites, cottage cheese, red pepper, sea salt, nutmeg, and black pepper together in a mixing bowl. Set aside.

Step 4: Assemble quiche. Returning to the greased pie pan, layer the grated cheese on the bottom. Then, add the spinach and onions and pour the quiche batter over the top.

Step 5: Bake quiche. Transfer to the oven and bake until the eggs are set (40 to 45 minutes). Let rest for 5 minutes before slicing. Enjoy!

Recipe Tips

  • To defrost the spinach, place it in a bowl under lukewarm running water and squeeze out as much moisture as possible.
  • Make a 1″ cut from the center towards the edges to check for doneness. If the knife comes out with any bits of egg on the blade, place it back in the oven for a few minutes.
  • You can prep most of this cottage cheese quiche in advance. The night before, make the vegetables and the egg batter and keep them stored separately in the fridge. The following day, assemble the quiche in your pie pan and bake!

Recipe FAQ

Is cottage cheese good in quiche?

In combination with a firmer shredded cheese (like cheddar), yes! Cottage cheese gives the quiche a smooth, rich consistency and makes everything taste better.

How do I reheat a slice of quiche?

The quickest way is to pop it in the microwave for 1 to 2 minutes. You can also reheat it on a baking sheet in the oven at 375. If you have the time, it’s best to reheat when the quiche is at room temperature.

Can I bake crustless quiche in a muffin tin?

I’ve only tried this one in a pie pan, but you can try baking the egg mixture in a greased muffin pan at 375F until a knife sliced through the middle comes out clean (20 to 25 minutes).

  1. Looks delicious! I sooo cannot wait to try this Amy! Thanks and Happy Mother’s Day 😉

    1. Hi Shannon! You can certainly swap whole eggs for the whites, but I haven’t tested the amount. That amount sounds about right, but I can’t say for sure without testing the recipe. If you try it, please let me know how it turns out!

    1. Hi Mary! You can saute 1-1 1/2 lbs of fresh spinach in a little olive oil until just wilted and sub that for the frozen. It takes a lot more fresh spinach because it wilts down so much when cooked.

  2. 5 stars
    I made this for the first time, and my husband loved it. The only thing I changed was fresh spinach instead of frozen since that’s what I had on hand. I’ll be serving it for the next brunch with the girls!

  3. Can you use FRESH spinach???? If so, do you need to sauté it first????? If you use 8 egg whites, what do you do with all the yolks?? I hate to be wasteful. My grocer doesn’t have frozen egg whites. Have never seen that in a grocery store.

    1. Hi Maxine! I just answered your questions in the recipe card, just in case someone else would like to make the same substitutions. I usually use liquid egg whites in the carton (these are located near the fresh eggs in the refrigerator section of the grocery store), however you can use 6 whole eggs in place of the egg white whole egg combo. For fresh spinach, one pound is equal to 10 oz of frozen. Cook the fresh spinach down in an oiled skillet until it has wilted down and add it to the quiche. I hope that helps!
