• ½ teaspoon salt
• ¼ teaspoon ground black pepper

Ingredient Notes and Variations

• Sausage: Use a mild or spicy ground breakfast sausage. Turkey sausage works well too.

• Cheese: Cheddar adds sharpness, but feel free to try Colby Jack or mozzarella for a melty twist.

Kitchen Equipment You’ll Need

• 9×13 inch baking dish
• Large skillet
• Mixing bowls
• Whisk
• Spatula
• Measuring cups and spoons
• Aluminum foil (for covering if needed)

Step-by-Step Preparation: How to Make Cheesy Sausage Breakfast Casserole

Step 1:
Preheat your oven to 350°F (175°C). Lightly grease a 9×13 inch baking dish and set aside.

Step 2:
In a large skillet over medium heat, cook the sausage until browned and crumbled. Drain excess fat and let it cool slightly.

Step 3:
In a large mixing bowl, whisk together the eggs, milk, salt, and pepper until fully combined.

Step 4:
Spread the thawed hash browns evenly into the prepared baking dish.

Step 5:
Top the hash browns with the cooked sausage, spreading it out evenly.

Step 6:
Sprinkle the shredded cheese evenly over the sausage layer.

Step 7:
Pour the egg mixture evenly over the top, ensuring everything is covered.

Step 8:
Bake uncovered for 45–50 minutes, or until the eggs are set and the top is golden brown. If the top browns too quickly, cover with foil during the last 10 minutes.

Step 9:
Let the casserole rest for 10 minutes before slicing and serving.

For a sweet pairing, serve with Grinch Dip or a refreshing glass of Breakfast Punch.
