Gather Your Ingredients
Before you begin, ensuring you have everything you need is essential. For this breakfast casserole, round up the following ingredients:
- 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
Make a quick check of your pantry and fridge. Some items like sour cream and kosher salt might be staples you already have!
Cook the Beef Sausage
Now that you have your ingredients ready, it’s time to cook the beef sausage. Heat a large skillet over medium heat and add the beef sausage. Breaking it into smaller pieces while it cooks gives you that perfect texture. Cook until it’s browned and fragrant—this should take about 5 to 7 minutes. Once done, drain the excess grease and set the sausage aside to cool slightly.
Prepare the Vegetable Mix
In the same skillet, toss in the diced green and red bell peppers along with the chopped green onions. Sauté for about 2 to 3 minutes until they become tender and vibrant. The aroma will be amazing, and this is a great time to appreciate the fresh ingredients you're using! Adding veggies not only boosts flavor but also adds some beautiful color to your breakfast casserole.
Combine the Egg Mixture
In a large mixing bowl, crack those eggs open—12 of them—and whisk them together. Add in your sour cream, milk, kosher salt, and ground black pepper. Mix everything on low speed with an electric mixer until just combined; this helps create a light, fluffy casserole. Now, gently fold in the cooked beef sausage and sautéed veggies from earlier, followed by the shredded cheddar cheese.
Bake to Perfection
Pour the entire mixture into a greased 9x13-inch baking pan and smooth it out evenly. Preheat your oven to 350 degrees Fahrenheit and place the casserole in for 35 to 50 minutes or until the edges are set and the center is just slightly jiggly. This is the moment of truth! Keep an eye on it and enjoy the warm, comforting scents wafting through your kitchen.
Congratulations! You’re now on your way to enjoying a delightful breakfast casserole that will delight friends and family alike. Leftovers can be stored in the fridge for 3-4 days, making this a perfect make-ahead meal for your busy mornings.

Variations on Breakfast Casserole
Vegetarian Breakfast Casserole
If you’re looking for a vegetarian twist on the classic breakfast casserole, swap out the beef sausage for a medley of your favorite veggies. Think spinach, mushrooms, and zucchini for a colorful and nutritious option. You can also add chickpeas or black beans for extra protein. Use a plant-based cheese or skip it entirely—this dish will still be packed with flavor!
Gluten-Free Breakfast Casserole
Craving a hearty gluten-free breakfast casserole? No problem! Just ensure you choose gluten-free bread as a base and check your cheese and sausage labels for any hidden gluten. You can even incorporate ingredients like quinoa or brown rice to boost nutritional value. This makes for a delicious, filling alternative perfect for brunch gatherings or meal prepping for the week ahead.
Feel free to get creative with herbs and spices!
Cooking Tips and Notes for Breakfast Casserole
Tips for Perfect Texture
For a light and fluffy breakfast casserole, whisk the eggs and sour cream thoroughly to incorporate air. Don’t overbake; keeping the center slightly jiggly ensures it will continue to set while cooling. Consider adding in some cubed day-old bread for extra texture and flavor—it's a great way to avoid food waste!
Reheating and Storage Tips
Store leftovers in an airtight container for up to 3-4 days in the fridge. When reheating, use the microwave in 30-second increments for the best results, or pop it in the oven at 350°F for a few minutes to keep that freshly-baked flavor. This breakfast casserole not only tastes great but is also a time-saver for busy mornings!
