Pork breakfast sausage is a classic choice and gives this casserole its iconic rich, savory taste. You can use spicy sausage for a kick or go with turkey sausage for a leaner option. Just make sure to cook and crumble it well before layering.

Ingredients for the Sausage Egg and Cheese Breakfast Casserole

Breakfast sausage: This is the heart of the flavor. Choose ground pork sausage for richness or turkey sausage for a lighter version.

Eggs: The base of the casserole, creating a custardy texture that holds everything together.

Cheddar cheese: Adds sharpness and meltiness. A good quality sharp cheddar will enhance every bite.

Milk: Balances the eggs and ensures a creamy, fluffy finish.

Baking mix (like Bisquick): Helps create that light, fluffy, almost biscuit-like texture underneath the eggs.

Salt and black pepper: Simple seasoning to elevate the dish.

Butter (for greasing): Prevents sticking and adds a buttery touch to the crust.

How To Make the Sausage Egg and Cheese Breakfast Casserole

Step 1: Cook and Crumble the Sausage

In a skillet over medium heat, cook 1 pound of breakfast sausage until browned and fully cooked. Break it up with a spoon into small crumbles. Drain excess grease and set aside.

Step 2: Preheat and Prepare the Dish

Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish generously with butter.

Step 3: Make the Egg Mixture

In a large bowl, whisk together 8 large eggs, 2 cups of milk, 1/2 teaspoon salt, and 1/4 teaspoon black pepper until smooth.

Step 4: Layer the Casserole

Sprinkle 1 1/2 cups of shredded cheddar cheese evenly over the bottom of the greased baking dish. Next, scatter the cooked sausage evenly on top of the cheese. In a separate bowl, combine 1 cup of baking mix with the egg mixture and pour everything over the sausage layer.

Step 5: Add Final Cheese and Bake

Sprinkle the remaining 1/2 cup of shredded cheddar cheese over the top. Bake uncovered for 35-40 minutes or until the center is set and the top is golden brown. Let it rest for 5-10 minutes before slicing.

Storing and Reheating Tips

Store leftovers in an airtight container in the refrigerator for up to 4 days. For best results, reheat slices in the oven at 325°F for about 10-15 minutes, or microwave individual portions for 1-2 minutes until heated through. You can also freeze individual pieces by wrapping them tightly and storing in a freezer-safe bag for up to 2 months.
