Can I really not taste the cottage cheese in this recipe?

Trust me on this one—the cottage cheese completely melts into the casserole, contributing amazing texture and protein without any of that distinctive cottage cheese taste or texture. Even devoted cottage cheese haters will be none the wiser!

Can I use different cheeses in this casserole?

Absolutely! While mozzarella provides that classic stretchy cheese pull, cheddar, Gruyère, or Monterey Jack work beautifully too. Just make sure to use a good melting cheese for best results.

How do I know when the casserole is fully cooked?

The casserole is done when the edges are set and golden brown, and the center is mostly set but still has a slight jiggle when you gently shake the pan. A knife inserted in the center should come out mostly clean.

Is this recipe gluten-free?

Not as written, but you can easily substitute a gluten-free flour blend for the all-purpose flour to make it gluten-free. The rest of the ingredients are naturally gluten-free.

How to Make Cheesy Egg Casserole

Step 1: Prepare Your Pan

Preheat your oven to 400°F and prepare your baking dish with a generous coat of nonstick spray. This ensures easy serving later!

Step 2: Mix the Eggs

In a large mixing bowl, lightly beat the eggs until just combined. Don’t over-beat them or you’ll incorporate too much air.

Step 3: Add Remaining Ingredients

Add the melted butter, cottage cheese, mozzarella, flour, baking powder, Italian seasoning, and salt to the beaten eggs. Stir until combined—but don’t worry about getting it perfectly smooth! Those little lumps of cheese will create pockets of deliciousness.

Step 4: Bake to Perfection

Pour the mixture into your prepared baking dish and bake for 30-40 minutes. You’ll know it’s done when the top is beautifully golden brown and the center is set but still has a slight jiggle.

Step 5: Rest Before Serving

Allow the casserole to cool for 5-10 minutes before slicing. This resting period helps the casserole set up properly for clean, beautiful slices.

Pro Tips for Making the Recipe

Room Temperature Ingredients: If you have time, let your eggs come to room temperature before mixing. This creates a fluffier texture.
Don’t Overmix: Stir just until combined—overworking the mixture can lead to a denser casserole.
Watch For Doneness: Every oven is different, so start checking at the 25-minute mark. The edges should be set and slightly pulling away from the sides of the dish.
Make-Ahead Magic: This casserole actually develops more flavor overnight, so don’t hesitate to make it the evening before a busy morning.

How to Serve

This versatile casserole works well with numerous pairings:

Breakfast Spread

Serve alongside fresh fruit, crispy hash browns, or buttered toast for a complete breakfast.

Brunch Star

Make it the centerpiece of a brunch buffet with muffins, fruit salad, and mimosas.

Light Dinner

Pair with a simple green salad dressed with vinaigrette for a satisfying, protein-rich evening meal.

Make Ahead and Storage

Storing Leftovers

Refrigerate leftover casserole in an airtight container for up to 4 days. The flavors actually develop nicely overnight!

Freezing

Cut the cooled casserole into individual portions and freeze in airtight containers or wrapped well in plastic wrap and foil. They’ll keep beautifully for up to 3 months.

Reheating

For refrigerated leftovers, microwave individual portions for 60-90 seconds. For frozen portions, microwave for 2-3 minutes, or until heated through. You can also reheat in a 350°F oven, covered with foil, until warmed through (about 15-20 minutes).
