Cottage Cheese Egg Casserole Recipe

Golden brown on top and fluffy in the middle, this cottage cheese egg casserole is a high protein breakfast that actually keeps you full. It’s loaded with eggs, green chiles, and plenty of melty cheddar so every bite has the perfect mix of flavor and veggies.

32 grams of protein per serving

The protein in this one comes straight from the heavy hitters: whole eggs, cottage cheese, and a big handful of shredded cheddar. Between the calcium, grams of protein, and that fluffy texture, it’s got all the makings of a solid high protein breakfast. I make this cottage cheese egg bake all the time, and it’s one of those recipes that slices clean, reheats well in the microwave, and never lasts long in the fridge.

Key ingredients and substitutions

Various ingredients for a cottage cheese casserole are arranged on a wooden surface, including eggs, cottage cheese, shredded cheese, diced green chilis, bacon, flour, and small bowls of powders.

Large eggs: The base of the casserole, giving structure and a fluffy texture. You can swap some for egg whites if you want fewer calories.
Cottage cheese: Adds protein and keeps the casserole moist. Full fat or low fat both work.
Cheddar cheese: Brings bold flavor and gooey texture. Sharp cheddar, Monterey Jack, or mozzarella cheese are all great swaps.
Green chiles: Add a gentle kick and extra flavor. Diced red bell pepper or tomatoes can work if you prefer milder veggies.
All-purpose flour: Helps bind the egg mixture together. For gluten-free, use a 1:1 gluten-free blend.
Bacon: Adds smoky flavor and crunch. Ham, turkey sausage, or breakfast sausage are all tasty alternatives.
Seasonings: Garlic powder and onion powder keep it simple, but you can stir in black pepper, salt, or even a pinch of chili flakes.

How to make cottage cheese egg casserole

Prep the dish: Line a 9×13-inch casserole dish with parchment paper or give it a good spray of olive oil cooking spray. Preheat the oven to 400°F (200°C).

Adjust heat: Turn the casserole around, reduce to 375°F (190°C), and continue baking for about 30 minutes or until set. A toothpick should come out clean.
Rest and slice: Let it cool for 10 minutes so it firms up, then slice into squares and serve.

Recipe notes and tips

Easy release: Line the casserole dish with parchment paper or spray well so nothing sticks.
Even bake: Rotate the dish halfway through cooking to keep the texture consistent.
Check doneness: Test the center with a toothpick – if it comes out clean, you’re good to go.
Golden top: Leave it in a few extra minutes if you like the cheese browned and bubbly.
Set texture: Let the casserole rest for 10 minutes before slicing so it holds together perfectly.

Storage instructions

Fridge: Store leftovers in an airtight container in the refrigerator for up to 4 days.
Freezer: Wrap individual slices in aluminum foil, then place in a freezer bag for up to 2 months.

Frequently asked questions

Can I prep this the night before?

Absolutely. You can mix everything together, cover the dish, and keep it in the fridge overnight. Just bake it fresh in the morning and give it a little extra time in the oven since it will be cold going in.

What kind of cottage cheese is best?

Full fat makes it rich and creamy, but reduced fat works if that’s what you’ve got. If the curds look a little chunky, you can blend it smooth before adding it to the eggs, but honestly I don’t bother.

Can I make this vegetarian?

Definitely. Just skip the bacon and load it up with extra veggies like peppers, mushrooms, or spinach. It still bakes up fluffy and full of flavor.

What if I want fewer calories?

You can swap some of the whole eggs for egg whites and/or go with low fat cottage cheese. It won’t taste quite as rich, but it will still be satisfying and high in protein.
