How to Make Breakfast Casserole
Follow these simple steps to prepare this delicious Breakfast Casserole:
Step 1: Preheat the Oven
Preheat your oven to 350 degrees Fahrenheit (175 degrees Celsius). While that’s heating up, grab a 9×13-inch pan and spray it generously with cooking spray to prevent sticking.
Step 2: Prepare the Egg Mixture
In a large bowl, combine the eggs, sour cream, milk, cheese, salt, and pepper. Use an electric mixer on low speed until everything is just combined, and don’t overdo it; we’re looking for fluffy, not foamy!
Step 3: Cook the Sausage
In a large skillet over medium heat, add the pork sausage. Cook it until it’s beautifully browned, breaking it into small pieces. Drain any excess grease, then transfer the cooked sausage into the egg mixture.
Step 4: Sauté the Vegetables
With the same skillet, toss in the diced bell peppers and chopped green onions. Sauté for about 2-3 minutes until they soften slightly. Add these vibrant veggies to the bowl with the eggs and sausage, stirring everything to create a colorful mix.
Step 5: Assemble and Bake
Pour the entire mixture into the greased 9×13-inch pan, spreading it evenly. Now it’s time for the magic! Bake in your preheated oven for 35-50 minutes, or until the edges are set, and the center looks just barely jiggly—like a good movie plot twist.
Step 6: Serve and Enjoy
Once baked to perfection, let the casserole cool for a few minutes. Cut into generous squares for serving. Pop them onto plates or into bowls and savor each delectable bite.
