- 1 16 ounce container (453g) cottage cheese
- 2 cups mozzarella cheese (approximately 8 ounces/226g)
- 1/4 cup (31g) all purpose flour
- 1 teaspoon baking powder
- 1 teaspoon Italian seasoning
- 1/2 teaspoon salt
- 10 large eggs, lightly beaten
Notes & Substitutions
Cottage cheese plays a key role, adding essential moisture and a lovely texture without imparting a strong cheesy flavor. For other cheeses, feel free to use sharp cheddar, Monterey Jack, or a blend of your favorites. If you are gluten-sensitive, simply swap the all-purpose flour for a cup-for-cup gluten-free all-purpose flour blend.
Boost the flavor with savory add-ins like sautéed vegetables or cooked breakfast meats. You can also experiment with different seasoning blends such as a pinch of smoked paprika or garlic powder.
Equipment
You will only need a few basic kitchen tools for this simple cheesy egg casserole:
- 9×13 inch baking dish
- Large mixing bowl
- Whisk for combining ingredients
- Nonstick cooking spray
Instructions

Follow these easy steps to create your delightful cheesy egg casserole. Remember, simplicity is key to a perfect outcome!
- Preheat Oven: Begin by preheating your oven to 400°F (200°C). Generously spray a 9×13 inch baking dish with nonstick cooking spray, ensuring no sticking.
- Whisk Eggs: In a large mixing bowl, lightly whisk the 10 large eggs until just combined and slightly frothy.
- Add Butter: Pour the melted butter into the whisked eggs, continuing to whisk until the butter is fully incorporated into the mixture.
- Combine Dry Ingredients: Next, stir in the all-purpose flour, baking powder, Italian seasoning, and salt into the egg mixture. Mix well to ensure there are no dry pockets.
- Fold in Cheeses: Gently fold in the entire container of cottage cheese and the mozzarella cheese. The mixture will have a slightly lumpy texture, which is perfectly normal.
- Pour and Bake: Pour the entire mixture into your prepared baking dish. Place it in the preheated oven and bake for 30-40 minutes, or until the top is golden brown and the center is set. A knife inserted into the middle should come out clean.
- Cool and Serve: Remove the casserole from the oven and let it cool for 5-10 minutes before slicing and serving. This resting period helps the casserole set properly.
Make-Ahead Option: To prepare this cheesy egg casserole the night before, simply follow steps 1-5. Cover the baking dish tightly with plastic wrap or foil and refrigerate overnight. The next morning, remove it from the fridge while your oven preheats, then bake as directed, adding an extra 5-10 minutes to the baking time if needed.
Pro Tips for the Best Cheesy Egg Casserole
Achieve the most delicious results with these simple pro tips.
- Whisk Vigorously: Whisking the eggs well incorporates air, leading to a lighter, fluffier texture in your casserole.
- Do Not Overbake: Overbaking can result in a rubbery texture. Watch for a golden-brown top and a set center.
- Quality Cheeses Matter: Using good quality, flavorful cheeses will significantly enhance the overall taste of your dish.
- Allow to Rest: Let the casserole cool for 5-10 minutes after baking. This resting period helps it set, making for cleaner slices.
- Melted Butter Benefits: Melted butter blends seamlessly, distributing richness and flavor evenly throughout the egg mixture.
- Ricotta Alternative: For an even creamier texture, consider using ricotta cheese instead of cottage cheese.
Serving, Storage, and Variations

Make this recipe work for any occasion with these helpful tips.
Serving Suggestions
Serve your delicious cheesy egg casserole alongside a fresh fruit salad for a balanced meal. It pairs wonderfully with crispy bacon or savory sausage links. For a heartier option, offer warm tortillas or a slice of buttered toast. Top individual servings with fresh salsa, sliced avocado, or a dollop of sour cream for added flavor.
Storage Instructions
To store leftovers, allow the casserole to cool completely. Transfer individual portions into airtight containers and refrigerate for up to 3-4 days. For longer storage, freeze individual slices, tightly wrapped, for up to 1-2 months. Thaw frozen portions overnight in the refrigerator or reheat directly from frozen in the microwave or oven. Reheat in the microwave until warm, or in a preheated oven at 300°F (150°C) until heated through.
Variations
- Vegetable Add-ins: Enhance your casserole with sautéed bell peppers, fresh spinach, sliced mushrooms, or caramelized onions.
- Meat Lovers: Incorporate cooked crumbled sausage, crispy bacon bits, or diced ham for a protein-packed meal.
- Spicy Kick: Add a touch of heat with diced green chilies, sliced jalapeños, or a pinch of cayenne pepper.
- Cheese Blends: Experiment with different cheese combinations such as Colby Jack, sharp cheddar, or grated Parmesan.
- Hash Brown Base: For extra heartiness, layer a base of cooked hash browns at the bottom of the dish before adding the egg mixture.
