Step‑by‑Step Instructions for Hash Brown Egg Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). While the oven warms up, grab a 9×13-inch casserole dish and generously grease it with cooking spray or butter. This will ensure that your delicious Hash Brown Egg Casserole doesn’t stick and will allow for easy serving later.
Step 2: Whisk the Egg Mixture
In a large mixing bowl, crack open 8 large eggs and pour in 2 cups of milk. Whisk these together until smooth, ensuring all egg yolks are fully integrated. Add in 1 chopped onion, 1 teaspoon of garlic powder, 1 teaspoon of paprika, salt, and black pepper to taste. Mix well until everything is combined, creating a savory base for your casserole.
Step 3: Combine the Hash Browns and Cheese
Once your egg mixture is blended, fold in 30 ounces of thawed shredded hash browns and 1½ cups of shredded cheddar cheese. If you’re using any optional add-ins like cooked sausage or sautéed vegetables, now’s the perfect time to stir those in! Make sure everything is well incorporated and the hash browns are evenly coated.
Step 4: Pour into the Casserole Dish
Carefully pour the hash brown and egg mixture into the prepared casserole dish. Spread it out evenly using a spatula to ensure an even cook. To add a finishing touch, sprinkle the remaining ½ cup of cheese over the top, followed by a light dusting of paprika for visual appeal.
Step 5: Bake the Casserole
Place the casserole in the preheated oven and bake uncovered for 45-50 minutes. You’ll know it’s done when the center is set, and the edges are golden brown. Keep an eye on the top to ensure it doesn’t over-brown; if it starts to darken too much, cover it loosely with foil.
Step 6: Cool and Serve
Once baked, remove the Hash Brown Egg Casserole from the oven and allow it to cool for about 10 minutes. This resting period helps it set for easier slicing. After cooling, cut into squares and serve warm, perhaps with some fresh fruit or a light salad on the side for a complete brunch experience.
