Getting this breakfast casserole just right is straightforward with these steps. Start by setting up your kitchen for success, and you’ll have a warm meal ready in no time. This guide uses the specific preparation method to ensure great results every time.

First, preheat your oven to 350 degrees Fahrenheit and spray a 9×13 inch baking pan with cooking spray to prevent sticking. In a large bowl, combine the 12 eggs, 1 cup of sour cream, 1/4 cup of milk, 2 cups of shredded cheddar cheese, 1 teaspoon of salt, and 1/2 teaspoon of ground black pepper, then mix on low speed until everything blends smoothly. Next, cook the 2 pounds of sausage in a large skillet over medium heat until it’s browned and broken into small pieces, then drain the grease and add it to the egg mixture.

Cooking the Vegetables

After adding the sausage, sauté the 1/2 diced green bell pepper, 1/2 diced red bell pepper, and 4 green onions in the same skillet for 2 to 3 minutes until they’re soft and fragrant. Stir these into the egg mixture to combine all flavors evenly. Pour the full mixture into your prepared pan and bake for 35 to 50 minutes, watching until the edges set and the center is slightly jiggly.

Final Touches

If you’re going vegan, use tofu or tempeh instead of eggs, and swap the 2 cups of shredded cheddar cheese with nutritional yeast or vegan cheese alternatives.

Category	Original Ingredient	Substitution Option
