Ingredients

• 1 pound breakfast sausage (Italian, spicy, or your favorite)
• 6 large eggs
• 1 cup milk
• 1 cup shredded cheddar cheese or preferred cheese blend
• 2 cups bread cubes (optional)
• ½ teaspoon salt
• ½ teaspoon black pepper
• ½ teaspoon garlic powder
• ¼ teaspoon smoked paprika
• ½ cup diced bell peppers (optional)
• ½ cup chopped spinach (optional)
• ¼ cup diced onions (optional)

Preparation Method

Preparing the Sausage

Preheat your oven to 375°F (190°C). Heat a large skillet over medium heat and cook the sausage until fully browned, breaking it apart with a spatula. If using spicy or flavored sausage, it will add extra depth of flavor to the casserole. Remove from heat and drain any excess grease.

Preparing the Egg Mixture

In a large mixing bowl, whisk together the eggs, milk, salt, black pepper, garlic powder, and smoked paprika. Make sure the spices are evenly incorporated to enhance the flavor of the casserole.

Assembling the Casserole

Grease a 9×13-inch baking dish lightly with butter or cooking spray. If using bread cubes, layer them evenly on the bottom of the dish. Spread the cooked sausage evenly over the bread (or directly into the dish if not using bread). Add the diced bell peppers, spinach, and onions evenly on top of the sausage.

Pour the egg and milk mixture over the layers, ensuring it covers the ingredients evenly. Sprinkle the shredded cheese over the top to create a golden, melty crust during baking.

Baking the Casserole

Bake uncovered in the preheated oven for 30-35 minutes, or until the eggs are fully set and the cheese is golden brown. You can test for doneness by inserting a knife into the center; it should come out clean. If the top begins to brown too quickly, cover loosely with foil for the last 10 minutes of baking.

Serving the Casserole

Allow the casserole to cool for 5 minutes before slicing. Serve warm, either on its own or with a side of fresh fruit, toast, or a light salad for a complete breakfast or brunch. This casserole can also be portioned into meal prep containers for an easy grab-and-go breakfast throughout the week.

Tips for a Perfect Sausage and Egg Casserole

1. Use fully cooked sausage: This ensures even flavor and saves time during assembly.
2. Customize vegetables: Add mushrooms, tomatoes, or zucchini for extra nutrition and variety.
3. Cheese options: Cheddar is classic, but Monterey Jack, mozzarella, or a blend work beautifully.
4. Make ahead: Assemble the casserole the night before and refrigerate. Bake in the morning for a convenient breakfast.
5. Bread cubes: Using day-old bread helps absorb the egg mixture without becoming soggy.
