Now that you have all the necessary ingredients for your Hashbrown Breakfast Casserole, it’s time to get cooking!
Step‑by‑Step Instructions for Hashbrown Breakfast Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This crucial step ensures that your Cheesy Hashbrown Breakfast Casserole bakes evenly. While the oven warms up, you can prepare the other ingredients, making the most of your time in the kitchen.
Step 2: Prepare the Baking Dish
Grease a 9×13-inch baking dish with non-stick cooking spray or a light coating of butter. This will prevent the casserole from sticking and help create a beautiful golden crust. Set the prepared dish aside as you move on to layering your ingredients.
Step 3: Layer the Hashbrowns
Spread the thawed hashbrowns evenly across the bottom of the greased baking dish. Use a spatula to flatten them out, creating an even layer. The hashbrowns will form the hearty base of your casserole, so ensure they cover the entire bottom.
Step 4: Add the Sausage
Next, sprinkle the cooked breakfast sausage over the layer of hashbrowns. Make sure the sausage is crumbled and distributed evenly to provide flavorful bites throughout the casserole. The savory sausage will enhance the overall taste of this delightful dish.
Step 5: Cheesy Layering
In a bowl, combine the shredded cheddar and mozzarella cheeses, then sprinkle half of this cheesy mixture on top of the sausage layer. The cheese will melt beautifully during baking, creating gooey, comfort-filled bites in your Hashbrown Breakfast Casserole.
Step 6: Prepare the Egg Mixture
In a separate bowl, whisk together the eggs, milk, salt, black pepper, and garlic powder until well combined and slightly frothy. This mixture will add richness and bind the casserole together, so be sure to incorporate plenty of air for a fluffy texture.
Step 7: Pour the Egg Mixture
Carefully pour the egg mixture evenly over the layered ingredients in the baking dish. Make sure to cover all the ingredients, allowing the egg to seep through and bind everything together. This step is essential for achieving the perfect consistency in your casserole.
Step 8: Add More Cheese
Sprinkle the remaining cheese mixture generously on top, creating a delicious cheesy crust for your casserole. This melty layer will create an appealing golden-brown finish as it bakes, making your Hashbrown Breakfast Casserole undeniably tempting.
Step 9: Optional Veggie Layer
If you wish, you can now scatter the diced bell peppers and onions evenly across the top of the cheese layer. These optional ingredients add a pop of color and extra flavor, enhancing the overall appeal of your breakfast casserole.
Step 10: Bake the Casserole
Place the baking dish in the preheated oven and bake for 45-50 minutes. You’ll know it’s ready when the casserole is set, bubbly, and the top is golden brown. Keep an eye on it during the last few minutes for that perfect finish.
Step 11: Cool and Serve
Once your Hashbrown Breakfast Casserole is baked to perfection, take it out of the oven and allow it to cool slightly for about 10 minutes. This will help the casserole set and make slicing easier. Cut into squares and enjoy a warm, hearty breakfast!
