Equipment
- 1 9x13 Glass Baking Dish
- 1 Large mixing bowl
- 1 Electric Mixer
- 1 Skillet
- 1 Meat Chopper or Wooden Spoon
Ingredients
- 2 pounds pork sausage
- 12 eggs
- 1 cup sour cream light or regular
- 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
Instructions
- Preheat Oven: Set your oven to 350°F (175°C) and lightly grease a 9x13-inch glass baking dish with cooking spray or butter. Proper preheating ensures even cooking and a golden, firm top.
- Mix Eggs and Dairy: In a large mixing bowl, combine all 12 eggs, 1 cup sour cream, 1/4 cup milk, salt, and pepper. Use an electric mixer on low speed to blend until smooth and slightly airy, avoiding overmixing.
- Cook the Sausage: Heat a large skillet over medium heat and add 2 pounds of pork sausage. Break the sausage into small pieces using a wooden spoon or meat chopper and cook until browned. Drain excess grease for a healthier casserole.
- Sauté Vegetables: In the same skillet, add diced green and red bell peppers along with chopped green onions. Sauté for 2–3 minutes until softened, enhancing flavor and preserving a slight crunch.
- Combine Ingredients: Add the cooked sausage and sautéed vegetables to the egg mixture. Stir gently to evenly distribute ingredients, ensuring every bite has a balanced mix of protein, cheese, and vegetables.
- Add Cheese and Pour: Fold in 2 cups of shredded cheddar cheese, then pour the complete mixture into the prepared 9x13 baking dish. Spread evenly to ensure uniform cooking throughout the casserole.
- Bake to Perfection: Bake in the preheated oven for 35–50 minutes. The casserole is done when the edges are set and the center is just slightly jiggly. Allow to rest for 5–10 minutes before serving to make slicing easier and maintain structure.
Notes
- Make Ahead Option: This casserole can be assembled the night before and stored in the fridge, making mornings stress-free. Bake directly from chilled.
- Customize Ingredients: Swap pork sausage for turkey sausage, chicken sausage, or a plant-based alternative. Add mushrooms, spinach, or tomatoes for extra veggies.
- Cheese Variations: Cheddar works perfectly, but Swiss, mozzarella, or pepper jack can be used for different flavor profiles.
- Cooking Time Adjustment: Oven temperatures vary; check at 35 minutes and bake longer if the center is still jiggly.
- Portion Control: This recipe serves 12; slice into squares or rectangles for easy serving and meal prep.
