Ingredients for Hash Brown & Egg Casserole

One of the biggest advantages of this recipe is its straightforward ingredient list. Each component plays a crucial role in flavor, texture, and structure.

Main Ingredients

• Frozen hash brown potatoes (2 pounds / 900 g, thawed)
  These form the base of the casserole. Thawing them ensures even cooking and prevents excess moisture.

• Small onion, diced
  Onion adds sweetness and depth, complementing the sausage beautifully.

• Large eggs (5)
  Eggs bind the casserole together and create a fluffy, custard-like texture.

• Milk (½ cup)
  Milk lightens the eggs and helps them bake evenly.

  Enhances the savory flavor without overpowering the dish.

• Garlic powder (⅛ teaspoon)
  A subtle background note that boosts overall flavor.

• Salt and ground black pepper, to taste
  Essential for balancing flavors.

• Shredded Cheddar cheese (12 ounces / 340 g)
  Cheddar provides bold flavor and melts beautifully, creating that irresistible cheesy finish.

Step-by-Step Instructions for Hash Brown & Egg Casserole

Making a Hash Brown & Egg Casserole is straightforward, even if you’re new to breakfast bakes. Follow these steps carefully for the best results.

Step 1: Preheat and Prepare the Baking Dish

Preheat your oven to 350°F (175°C). Grease a deep 8×8-inch (20×20 cm) baking dish thoroughly. This step is important, as the casserole is thick and cheesy, and proper greasing prevents sticking.

Step 2: Add the Hash Browns

Spread the thawed hash brown potatoes evenly across the bottom of the dish. Press them gently into an even layer. This ensures the potatoes cook consistently and form a solid base.

Step 3: Cook the Sausage and Onion

In a large skillet over medium heat, cook the pork sausage and diced onion together. Break the sausage into crumbles and cook until fully browned and no longer pink, about 10 minutes. Drain any excess grease and set the mixture aside.

Step 4: Whisk the Egg Mixture

In a large bowl, whisk together the eggs, milk, onion powder, garlic powder, salt, and black pepper until smooth and well combined. This mixture is the backbone of the Hash Brown & Egg Casserole, so ensure everything is evenly incorporated.

Step 5: Assemble the Casserole

Pour the egg mixture evenly over the hash browns. Sprinkle half of the shredded Cheddar cheese over the eggs. Add the cooked sausage and onion mixture on top, then finish with the remaining cheese.

Step 6: Bake Covered

Cover the dish tightly with aluminum foil and bake for 1 hour. This allows the eggs to set gently without over-browning the top.

Step 7: Bake Uncovered

Remove the foil and return the casserole to the oven for an additional 10 minutes, or until a knife inserted into the center comes out clean.

Step 8: Rest and Serve

Let the Hash Brown & Egg Casserole rest for about 5 minutes before slicing. This helps it firm up and makes serving easier.

Tips for the Perfect Hash Brown & Egg Casserole

Even a simple recipe benefits from a few expert tips. These insights will help you achieve the best possible results every time.

Pan Depth Matters

This casserole is thick. If your baking dish is shallow, consider using a 9×13-inch pan instead and begin checking for doneness around 50–55 minutes.

Don’t Skip Thawing the Hash Browns

Frozen hash browns release moisture as they cook. Thawing and draining them prevents a watery casserole and ensures crispier potatoes.

Season in Layers

Season the egg mixture well, but also taste the sausage before adding extra salt. Some sausages are saltier than others.

Rest Before Cutting

Allowing the casserole to rest after baking helps the eggs finish setting and makes clean slices possible.

Vegetable Add-Ins

Cheese Swaps

Meat Alternatives

• Use turkey sausage for a lighter option
