How to Make Cheesy Potato Breakfast Casserole
Step 1: Prep the Oven and Dish
Preheat your oven to 350°F (175°C). Preheating ensures even cooking throughout the casserole. Spray a medium casserole dish (a 9×13 inch dish is ideal) with non-stick spray. An 8×8 inch dish can be used, but you may need to adjust the baking time. Set the prepared dish aside.
Step 2: Cook Sausage and Onions
Prepare the sausage and onions. Sauté the onions in the sausage grease until they are softened and fragrant. Make sure the sausage is cooked thoroughly for the best flavor and texture.
Step 3: Combine Ingredients
In a large mixing bowl, combine all the ingredients, including the cooked sausage and onions, eggs, milk, frozen diced hash browns, and grated cheddar cheese. Grate the cheese evenly to ensure it melts uniformly throughout the casserole. Ensure all ingredients are well combined in the bowl. Reserve roughly one cup of the cheese for topping.
Step 4: Bake the Casserole
Pour the mixture into the prepared casserole dish. Bake for 35 minutes, or until the eggs are mostly set. Remove from the oven and top with the reserved cheese. Return the casserole to the oven for an additional 8 minutes. Reserving the cheese for the last few minutes of baking ensures better melting and browning.
Step 5: Rest and Serve
Allow the casserole to rest for 15-20 minutes before serving. Resting allows the casserole to set properly, making it easier to slice. Serve and enjoy!
Freezing and Reheating Instructions
Freezing:
You can freeze the casserole either before or after baking. To freeze, use freezer-safe containers or wrap tightly in plastic wrap and foil. The casserole can be frozen for up to 3 months.
Reheating:
From frozen: Bake at 350°F (175°C) covered with foil for approximately 60-75 minutes, or until heated through.
From refrigerated: Bake at 350°F (175°C) covered with foil for approximately 20-30 minutes, or until heated through.
Microwave Reheating: Individual portions can be microwaved, but the texture may be slightly different.
Pro Tips & Troubleshooting
Pro Tips
