Preparing Breakfast Casserole
Making a breakfast casserole can seem daunting, but this step-by-step guide will ease you into it. Not only is this dish delicious, but it’s also perfect for meal prep or feeding a crowd. Let’s get started!
Preheat the Oven
Before you dive into the mixing process, it’s essential to preheat your oven to 350 degrees Fahrenheit. This ensures that your casserole cooks evenly and thoroughly. While your oven is warming up, grease a 9x13-inch baking pan with your favorite cooking spray. This simple step will help prevent sticking, making cleanup a breeze later on.
Cook the Beef Sausage
Next up is cooking the star of the dish: beef sausage. Heat a large skillet over medium heat. Once hot, add the beef sausage, breaking it apart with a wooden spoon as it browns. You’ll want to cook it until it’s fully browned—this typically takes about 6 to 8 minutes. After that, be sure to drain most of the grease to keep your casserole from becoming overly greasy. Once drained, transfer the sausage to a mixing bowl where you'll combine all the other delicious ingredients.
Mix the Egg Mixture
In your large bowl, gather the other essential components for your casserole: 12 eggs, 1 cup of sour cream, ¼ cup of milk, salt, and pepper. Whisk these ingredients together until they’re just combined. You’re looking for a uniform consistency, and using an electric mixer on low speed can help speed up this process. Feel free to sneak a taste here; the cheese and sausage will add lots of flavor!
Combine Ingredients
Now it's time to add in the veggies and those tasty beef sausages. Sauté 4 green onions, ½ green bell pepper, and ½ red bell pepper in the same skillet you used for the sausage for about 2-3 minutes. This quick cooking will enhance their flavors. Once done, mix these in with your egg mixture, stir well, and finally, fold in 2 cups of shredded cheddar cheese. You’re creating a hearty medley that will make your breakfast casserole truly irresistible.
Bake the Casserole
Pour the combined mixture into your greased baking pan. Pop it into the preheated oven and let it bake for 35 to 50 minutes. You’ll know it’s ready when the edges are set and the center has a slight jiggle. Let it cool for a minute or two before serving; this will help it set further, making it easier to slice.
Your breakfast casserole is now complete and perfect for a family brunch or a cozy morning in. Enjoy this satisfying dish with your favorite toppings like hot sauce or fresh herbs. Happy cooking!
