What You’ll Need
Gather these ingredients to whip up your breakfast casserole:
- 2 pounds pork sausage
- 12 eggs
- 1 cup sour cream
- 1/4 cup milk
- 1 teaspoon kosher salt
- 1/2 teaspoon ground black pepper
- 4 green onions, chopped
- 1/2 green bell pepper, diced
- 1/2 red bell pepper, diced
- 2 cups shredded cheddar cheese
Substitutions could be simple—swap in turkey sausage for a lighter version or use non-dairy milk if you’re avoiding lactose.

Directions to Follow
- Preheat your oven to 350°F (175°C). Spray a 9×13-inch pan with cooking spray.
- In a large bowl, combine the eggs, sour cream, milk, shredded cheddar cheese, kosher salt, and black pepper. Use an electric mixer on low speed until just combined.
- Heat a skillet over medium heat. Add the pork sausage, cooking until browned and crumbly. Drain excess grease, then stir the sausage into the egg mixture.
- In the same skillet, sauté the diced green and red bell peppers along with the chopped green onions for 2-3 minutes. Fold this vegetable mixture into the egg mixture.
- Pour the combined mixture into the greased pan. Bake for 35-50 minutes or until the edges are set and the center has a slight jiggle.
- Allow the casserole to cool slightly before cutting and serving.
Best Ways to Enjoy It
When it’s time to serve your breakfast casserole, get creative! It pairs wonderfully with a simple green salad or sliced fresh fruit for a refreshing contrast. For an extra kick, consider topping it with salsa or avocado slices. A side of crispy breakfast potatoes can also elevate your brunch game!
Storage and Reheating Tips
After enjoying your casserole, make sure to store the leftovers properly. Allow it to cool completely before covering it tightly with plastic wrap or transferring it to an airtight container. Refrigerated, it will last for about three to four days. For reheating, a few minutes in the microwave or about 15-20 minutes in a 350°F oven will bring it back to life!
Helpful Cooking Tips
To ensure your breakfast casserole turns out perfectly every time, here are a few tips:
- Whisk the egg mixture until just combined; over-mixing can lead to a dense texture.
- Let it cool for at least 10 minutes before slicing. This will help it set and make serving easier.
- Consider adding spices like paprika or a touch of hot sauce for an extra flavor boost!
Recipe Variations
Feeling adventurous? Here are a few variations to try:
- Vegetarian Version: Substitute sausage with extra veggies like spinach, mushrooms, or zucchini.
- Spicy Kick: Add jalapeños or a dash of cayenne pepper for heat.
- Herb Infusion: Fresh herbs like basil or cilantro can bring a fresh twist to the flavor profile.
