Ingredients

• 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, sliced
• 1/2 green bell pepper, diced
• 1/2 red bell pepper, diced
• 2 cups shredded cheddar cheese

The ingredients blend beautifully, with the pork sausage providing a savory base, while the eggs and cheese create a fluffy texture. The bright flavors of green onions and bell peppers add freshness and crunch. If you’re looking to simplify, you can always use pre-packaged sausage, or even try vegetarian sausage for a meatless option!

Ingredient Notes and Easy Substitutions

• Sausage: Feel free to use turkey sausage or chicken sausage if you’re looking for a healthier option. For a vegetarian version, consider plant-based sausage or omitting it entirely and increasing the amount of veggies.
• Cheese: While cheddar cheese is classic, feel free to experiment with other cheeses like pepper jack for a spicy kick or mozzarella for a milder taste.
• Veggies: Mix in other vegetables such as spinach or mushrooms for added nutrition and flavor.
• Milk: Any kind of milk will work—dairy or non-dairy alternatives like almond milk or oat milk are great substitutions.

Instructions

1. Preheat your oven to 350 degrees F (175 degrees C) and spray a 9×13 inch pan with cooking spray.
2. In a large bowl, combine 12 eggs, 1 cup sour cream, 1/4 cup milk, 2 cups shredded cheddar cheese, 1 teaspoon kosher salt, and 1/2 teaspoon ground black pepper. Mix on low speed until well combined.
3. In a skillet over medium heat, cook the 2 pounds of pork sausage until it’s browned, breaking it into pieces with a spatula. Once cooked, drain excess grease and add the sausage to the egg mixture.
4. In the same skillet, add 1/2 green bell pepper, 1/2 red bell pepper, and 4 sliced green onions. Sauté for 2-3 minutes until the veggies are just tender, then combine with the egg-sausage mixture.
5. Pour the entire mixture into the greased pan and spread evenly.
6. Bake for 35 to 50 minutes, or until the casserole is set and the top is lightly golden. Keep an eye on it during the final minutes of baking.
7. For make-ahead, you can store the unbaked casserole in the fridge overnight. If you want to freeze it, cover tightly and freeze for up to 2-3 months; thaw before baking.

Expert Tips for the Best Results

• Cooking Sausage: Ensure the sausage is fully cooked and well-browned to enhance the flavors—this step is crucial for a rich taste.
• Don’t Overmix: When combining the egg mixture, mix just until combined to keep the eggs fluffy.
• Baking Time: Depending on your oven and the size of your dish, baking times may vary. Start checking at 30 minutes to avoid over-baking.
• Cooling: Let the casserole cool for a few minutes before slicing. This allows the eggs to set further, making for neater servings.

Variations

• Mexican Breakfast Casserole: Add black beans, corn, and diced jalapeños, and use pepper jack cheese for a spicy flair.
• Mediterranean Twist: Incorporate chopped spinach, kalamata olives, and feta cheese for a Mediterranean vibe.
• Italian Style: Use Italian sausage, add diced tomatoes, and substitute mozzarella for a different flavor profile.
• Veggie-Loaded: Increase the quantity of vegetables or add favorites like zucchini or mushrooms for a nutrient boost.
• Gluten-Free: Ensure any sausage and other processed ingredients you use are gluten-free for a safe option.

Serving Suggestions

This Breakfast Casserole pairs wonderfully with a variety of sides. Serve it alongside fresh fruit salads for a refreshing contrast, or offer a selection of salsas and sauces for a touch of zing. If you’re in the mood for a complete meal, consider adding crispy hash browns or toasted muffins. Complement your breakfast with hot coffee, freshly squeezed juice, or even mimosas for a celebratory touch.

Storage and Reheating

After enjoying your delicious casserole, leftovers can be stored in an airtight container in the refrigerator for up to 4 days. For longer storage, you can freeze pieces wrapped in plastic wrap and then sealed in a freezer bag for 2-3 months. To reheat, simply thaw in the refrigerator overnight and bake at 350 degrees until heated through, about 10-15 minutes.

Common Mistakes to Avoid

• Skipping the Greasing: Always grease your pan well to prevent sticking and ensure easy removal.
• Not Cooking the Sausage Properly: Undercooked sausage can lead to food safety issues; make sure to cook it thoroughly before adding to the egg mixture.
• Rushing the Baking: Allow the casserole to bake fully; undercooked eggs can lead to a mushy texture.
