Preparing Breakfast Casserole
When it comes to breakfast, nothing beats the warming comfort of a delicious Breakfast Casserole. Whether you're prepping for a busy workweek or hosting a brunch, this all-in-one dish is a crowd-pleaser that’s as easy to make as it is satisfying. Let’s dive into the preparation process step by step to create your mouthwatering Breakfast Casserole.
Gather Your Ingredients
The first step to creating your Breakfast Casserole is to gather all your ingredients. Having everything at your fingertips will make the cooking process smoother and more enjoyable. Here’s what you need:
- 2 pounds of beef sausage
- 12 eggs
- 1 cup of sour cream (light or regular)
- ¼ cup of milk
- 1 teaspoon of kosher salt
- ½ teaspoon of ground black pepper
- 4 green onions
- ½ green bell pepper (diced)
- ½ red bell pepper (diced)
- 2 cups of shredded cheddar cheese
Before you start, it’s always a good idea to wash and prep your vegetables. A clean cooking environment sets the tone for a great meal!
Mix the Egg Base
Once you have everything assembled, it's time to mix the egg base. In a large mixing bowl, whisk together the eggs, sour cream, milk, salt, and pepper. Use an electric mixer on low speed just until combined—this will provide a smooth, creamy texture. You want to avoid over-mixing, which could lead to a rubbery consistency.
Cook the Beef Sausage
Now, let’s get cooking! In a large skillet over medium heat, add the beef sausage. Cook it until it's nicely browned, breaking it apart with a wooden spoon. This usually takes about 8-10 minutes. Remember to drain most of the grease before adding it to your egg mixture for a healthier dish.
Sauté the Vegetables
Next up is the fun part: sautéing your veggies! In the same skillet, toss in the diced bell peppers and chopped green onions. Sauté them for 2-3 minutes until they’re vibrant and slightly tender. This step enhances their flavors and adds a delightful crunch to your Breakfast Casserole.
Combine and Bake the Casserole
Now, it’s time to bring everything together. Pour the cooked sausage and sautéed vegetables into the bowl with your egg mixture. Stir gently to combine all the ingredients. Pour the mixture into a greased 9x13-inch pan and sprinkle the top with some extra cheese for that ooey-gooey finish.
Place the casserole in a preheated oven at 350 degrees Fahrenheit and bake it for 35-50 minutes. Keep an eye on it! You’re looking for edges that are set while the center remains just barely jiggly.
And there you have it! Your Breakfast Casserole is ready to be enjoyed. Allow it to cool slightly before serving, and don't hesitate to save leftovers for easy breakfasts throughout the week. Enjoy!

Variations on Breakfast Casserole
Vegetarian Breakfast Casserole
For a delicious vegetarian twist on your classic breakfast casserole, skip the meat and load up on vibrant veggies! Think mushrooms, spinach, and zucchini, all sautéed to enhance their flavors.

This variation is perfect for a hearty weekend brunch with friends.
Southwestern Breakfast Casserole
Bring a spicy kick to your table with a Southwestern breakfast casserole! Combine the traditional egg mixture with roasted jalapeños, black beans, and corn for a zesty flavor profile.
