Why This Recipe Works (Quick Science)
Eggs are full of protein that firms up as they cook, creating the structure of the casserole. Cottage cheese adds even more protein while keeping the eggs moist because it holds onto water during baking. Cheddar cheese melts into the eggs, adding flavor and richness. Baking everything together slowly gives the casserole a soft, fluffy texture instead of becoming rubbery.
Pro Tips
- Drain extra liquid from the cottage cheese if it looks very watery.
- Chop the vegetables into small, even pieces so they cook evenly.
- Let the casserole rest for about 10 minutes before slicing for cleaner pieces.
- Freshly shredded cheddar melts better than pre-shredded cheese.
- Don’t overbake. The center should be just set.
Substitutions and Variations
- Swap cheddar for mozzarella, Monterey Jack, or Swiss cheese.
- Add cooked turkey sausage or diced ham for even more protein.
- Replace spinach with chopped kale.
- Use diced mushrooms or broccoli instead of bell peppers.
- Add crushed red pepper flakes for a little heat.
Make Ahead Tips
Prepare the entire casserole mixture the night before and cover it tightly in the refrigerator. Bake the next morning as directed. You can also bake the casserole completely, cool it, slice it, and refrigerate individual portions for quick breakfasts throughout the week.
Recipe
Step 1: Preheat and Prepare the Baking Dish
Preheat the oven to 375°F (190°C). Brush 1 tablespoon olive oil evenly over the bottom and sides of a 9×13-inch baking dish.

In a large bowl, whisk together 10 large eggs, 2 cups cottage cheese, ½ teaspoon garlic powder, ½ teaspoon paprika, ½ teaspoon salt, and ¼ teaspoon black pepper until smooth and well combined.
Step 3: Add the Vegetables and Cheese
Fold in 2 cups chopped spinach, 1 cup diced bell pepper, ½ cup diced onion, and 1 cup shredded cheddar cheese until everything is evenly mixed.
Step 4: Fill the Baking Dish
Pour the mixture into the prepared baking dish. Spread it into an even layer using a spatula.
Step 5: Bake
Bake for 35 to 40 minutes until the eggs are fully set and the top is lightly golden.
Step 6: Rest, Garnish, and Serve
Let the casserole rest for 10 minutes. Sprinkle with 1 tablespoon chopped fresh parsley. Slice into 8 servings and serve on a white round ceramic plate.
