How to Make Cheesy Egg Casserole

This casserole is quick to prepare and uses pantry staples, which means no last-minute grocery store runs. It’s perfect for beginner cooks or anyone short on time. You simply combine everything in one bowl, bake it, and enjoy!

Ingredients You’ll Need

Here’s what you need to make this easy egg casserole bake:

• ½ cup (113g) unsalted butter, melted: Adds richness and ensures a golden crust.
• 1 16-ounce container (453g) cottage cheese: Gives the casserole a creamy texture and an extra boost of protein.
• 2 cups mozzarella cheese (approximately 8 ounces/226g): For all that melty, cheesy goodness.
• ¼ cup (31g) all-purpose flour: Helps bind the casserole and give it structure.
• 1 teaspoon baking powder: Adds just the right amount of fluffiness.
• 1 teaspoon Italian seasoning: For a subtle burst of herby flavor.
• ½ teaspoon salt: Enhances all the flavors!
• 10 large eggs, lightly beaten: The star ingredient that holds everything together.

Special Tool: You’ll need a 9×13-inch baking dish for this recipe. A whisk and mixing bowl are all you need for prep—no fancy tools required!

Step-By-Step Instructions

Follow these easy steps to create your warm and satisfying oven-baked cheesy casserole:

1. Preheat your oven: Start by preheating your oven to 400°F. Spray a 9×13-inch baking dish with nonstick cooking spray so the casserole doesn’t stick.
2. Whisk the eggs: In a large mixing bowl, lightly whisk the eggs until combined. This will make your casserole light and fluffy.
3. Add the remaining ingredients: Stir in the melted butter, cottage cheese, mozzarella cheese, flour, baking powder, Italian seasoning, and salt. The mixture will look a little lumpy, but that’s totally normal!
4. Bake: Pour the mixture into the prepared baking dish. Pop it into the oven and bake for 30-40 minutes, or until the top is golden brown and the center is completely set. You’ll know it’s done when a toothpick inserted in the center comes out clean.
5. Cool and serve: Let the casserole cool for 5-10 minutes before slicing into squares. Serve warm and enjoy!

Bonus: If you’re into meal prepping, you can slice the casserole into portions, store them in individual containers, and freeze them. A quick microwave reheat, and breakfast is served!

Jake’s Tips for Perfect Cheesy Egg Casserole

Here are some extra pointers to make this recipe foolproof:

• Make it ahead: Assemble the casserole the night before and let it sit in the fridge. Before baking, allow it to come to room temperature (about 30 minutes) for even cooking.
• Customize the flavor: Add sautéed veggies like bell peppers, spinach, or mushrooms for extra nutrition, or mix in crumbled sausage or bacon for a smoky touch.
• Double-check the cottage cheese: Don’t worry! You won’t taste the cottage cheese—it’s there for texture and protein. If you’re still unsure, you can use ricotta as a substitute.
• Storage tips: This casserole stores beautifully. Keep leftovers in the fridge for up to 3 days or freeze individual portions for up to 3 months. Defrost in the microwave and enjoy!
