How to Make Three Cheese Italian Breakfast Casserole
Step 1: Preheat the Oven
Preheat your oven to 350°F. This ensures that your casserole bakes evenly from the start.
Step 2: Prepare the Dry Ingredients
Sift together the flour, salt, and baking powder into a small bowl. This step helps incorporate air into the mixture for a fluffier casserole.
Step 3: Beat the Eggs
In a large bowl, beat the eggs using an electric mixer at medium-high speed until they double in volume, approximately 3 minutes.
Step 4: Combine Ingredients
Add the melted butter and sifted flour mixture to the beaten eggs. Mix well at low speed. Then fold in the grated cheeses, diced roasted peppers, and chopped green onion until evenly distributed.
Step 5: Bake the Casserole
Pour the mixture into a buttered 8 x 8 casserole dish. Bake in the center of the oven until the top is golden brown and a tester comes out clean—about 30 to 40 minutes. Let it stand for 5 minutes before serving.
Step 6: Serve and Enjoy!
Cut into squares to serve. For added flavor, garnish each piece with a dollop of sour cream and finely chopped heirloom tomatoes. Enjoy your delicious Three Cheese Italian Breakfast Casserole!

Common Mistakes to Avoid
Making the Three Cheese Italian Breakfast Casserole can be a delightful experience, but there are some common pitfalls to watch out for.
