Step‑by‑Step Instructions for Egg Hashbrown Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While the oven warms up, grease an 8-inch square baking pan with cooking spray or butter to ensure the Egg Hashbrown Casserole comes out effortlessly after baking.
Step 2: Prepare the Hashbrowns
Spread the thawed frozen hashbrowns evenly in the greased baking pan, pressing them down slightly to create a firm base. Make sure the hashbrowns are distributed uniformly, as this will set the foundation for your delicious casserole and help achieve a crisp texture.
Step 3: Cook the Sausage and Onion
In a skillet set over medium heat, cook the pork sausage along with the diced onion. Use a wooden spoon to break up the sausage as it cooks, allowing it to brown evenly for about 10 minutes. Once cooked, drain any excess fat to keep the casserole light and tasty.
Step 4: Whisk the Egg Mixture
In a large mixing bowl, whisk together the eggs, milk, onion powder, garlic powder, salt, and black pepper until fully combined. This mixture should be well-emulsified and light, creating the perfect custard to bind your Egg Hashbrown Casserole.
Step 5: Assemble the Casserole
Pour the egg mixture evenly over the layer of hashbrowns, making sure to cover them completely. Sprinkle half of the shredded cheddar cheese on top, followed by the cooked sausage and onion mixture, ensuring even distribution for flavor in every bite.
Step 6: Top with Cheese
Next, add the remaining cheddar cheese over the sausage layer, covering it generously. This layer will melt beautifully during baking, creating a creamy and delicious topping that contrasts wonderfully with the crispy hashbrowns below.
Step 7: Cover and Bake
Cover the baking pan tightly with aluminum foil, which prevents excess browning and allows the casserole to cook evenly. Place it in the preheated oven and bake for 1 hour. This ensures the egg sets and all the flavors meld together beautifully.
Step 8: Uncover and Finish Baking
After 1 hour, carefully remove the foil and return the casserole to the oven. Bake for an additional 10 to 15 minutes until the cheese is bubbling and golden brown. Look for a slightly crisped top as a sign that your Egg Hashbrown Casserole is perfectly done.
Step 9: Cool and Serve
Once the casserole is baked, remove it from the oven and allow it to cool for 5 minutes. This brief cooling period helps the dish set up, making it easier to slice into perfect squares for serving. Enjoy this hearty breakfast delight with your loved ones!
