Ingredients

• Breakfast sausage – Provides savory flavor and hearty texture; choose mild or spicy depending on your preference.
• Eggs – The base of the casserole, creating structure and a fluffy texture when baked.
• Milk – Helps lighten the eggs and creates a tender, custard-like consistency.
• Shredded cheddar cheese – Adds sharp, melty richness throughout the casserole.
• Mozzarella cheese – Contributes extra creaminess and a beautiful golden top.
• Cooked breakfast potatoes or hash browns – Add substance and make the dish more filling.
• Cooked bacon (optional) – Brings smoky flavor and crispy texture.
• Green onions or chives – Add freshness and mild onion flavor.
• Salt and black pepper – Enhance and balance all the flavors.

How To Make the Sausage Egg And Cheese Breakfast Casserole

Step 1: Brown the Sausage

Cook the breakfast sausage in a large skillet over medium heat until fully browned and no pink remains. Break it into crumbles as it cooks. Drain excess grease and set aside.

Step 2: Prepare the Baking Dish

Lightly grease a casserole dish to prevent sticking. Spread the cooked breakfast potatoes evenly across the bottom of the dish to create the base layer.

Step 3: Layer the Meat and Cheese

Sprinkle the cooked sausage evenly over the potatoes. Add the shredded cheddar and mozzarella cheese, distributing it evenly so every bite gets that melty goodness.

Step 4: Mix the Egg Mixture

In a large bowl, whisk together the eggs, milk, salt, and black pepper until smooth and fully combined.

Step 5: Assemble the Casserole

Pour the egg mixture evenly over the layered ingredients in the baking dish. Gently tap the dish on the counter to help the mixture settle.

Step 6: Bake Until Set

Bake in a preheated oven until the center is set and the top is golden brown. The casserole should not jiggle in the center when gently shaken.

Step 7: Rest and Garnish

Allow the casserole to rest for several minutes before slicing. Garnish with chopped green onions or chives and optional crispy bacon before serving.
