How to Prepare the Perfect Breakfast Casserole: Step-by-Step Guide
Getting started with this breakfast casserole is straightforward, and it begins with preheating your oven. Set it to 350 degrees Fahrenheit and grease a 9×13 inch baking pan to avoid any sticking issues. In a large bowl, combine the 12 eggs, 1 cup sour cream, 1/4 cup milk, 2 cups shredded cheddar cheese, 1 teaspoon salt, and 1/2 teaspoon ground black pepper, mixing until just combined.
Next, brown 2 pounds of sausage in a skillet, breaking it into small pieces, and drain most of the grease before adding it to the egg mixture. Then, in the same skillet, sauté the diced 1/2 green bell pepper, 1/2 red bell pepper, and 4 chopped green onions for 2 to 3 minutes. Stir everything together and pour the mixture into the prepared pan.
Bake for 35 to 50 minutes, or until the edges are set and the center is slightly jiggly. Remember, the casserole will firm up as it cools, so don’t worry if it’s not completely solid right away. The total prep time is about 10 minutes, with cooking taking 35 to 50 minutes, making the whole process around 1 hour and 5 minutes.
Adapting for Dietary Needs
