This Egg Casserole with Cottage Cheese is the ultimate easy breakfast or brunch dish that’s both hearty and healthy. It’s packed with protein from eggs and cottage cheese, loaded with savory flavor from cheddar cheese and garlic powder, and baked until golden in a baking dish.

This breakfast casserole is another go-to favorite of mine. Sometimes I add a dollop of Roasted Garlic Butter on top—it adds instant flavor oomph.
For me, casseroles are a go-to when I need something quick and comforting. Plus, you can toss in just about any veggies or cheese you have on hand, making it the ideal "clean out the fridge" meal.

What's the Difference Between a Frittata and a Casserole
A frittata (frih-TAH-tuh) is an Italian egg-based dish similar to an omelet, its typically cooked on the stovetop but finished in the oven and often served sliced.
A casserole (kas-er-ohl) is baked entirely in a baking dish with various ingredients layered or mixed, typically containing meat, vegetables, and cheese.
Think of this casserole as the cozier, “feed-the-family” version of a frittata — all the flavor, less fuss.
Ingredients You'll Need
Here’s what you’ll need for this easy breakfast casserole:
- Eggs: The base of the casserole, bringing richness and structure. Choose fresh and large eggs.
- Cottage cheese: Provides a creamy texture and boosts protein. Use Low-fat of full-fat cottage cheese.
- Garlic: Enhances flavor with a subtle, aromatic kick. Use fresh or garlic powder.
- Cheddar cheese: Melts beautifully into the egg bake.
- Onion: Adds sweetness and depth to the dish.
- Mushrooms (optional): Use fresh or dried for an earthy flavor that complements the eggs.

- Add a final layer of cheddar cheese before baking for a golden crust.
Recipe FAQs
Cottage cheese makes your egg casserole creamier and higher in protein without adding extra fat. Because it has more moisture than heavy cream, it helps keep the eggs soft and fluffy — but it may also slightly increase the baking time. If your cottage cheese is very wet, you can drain off a bit of liquid or add an extra tablespoon of shredded cheddar cheese to balance it out.
It depends on the texture you prefer! If you want a light and fluffy casserole, there’s no need to drain the cottage cheese — the moisture helps keep the eggs tender. For this recipe, I blend the cottage cheese in a blender or food processor so it’s smooth, not chunky, and evenly distributed throughout the casserole.
Yes, ricotta works well as a substitute for cottage cheese. It creates a slightly denser, creamier texture and a richer flavor. Just note that ricotta doesn’t have the same tanginess, so you may want to add a pinch of salt or a little extra cheddar cheese to balance it.
A watery casserole usually means one of two things:
Undercooked center – bake until the middle is fully set (it should jiggle slightly, not slosh).
Too much moisture from veggies – try sautéing mushrooms, spinach, or bell peppers first to release excess water before mixing.
Absolutely! Divide the mixture into greased muffin tins or small ramekins and bake at 350°F for 18–22 minutes, or until set. It’s a great way to make individual portions for grab-and-go breakfasts or brunch buffets.
