Ingredients
  

  • 1 lb 0.45 kg breakfast sausage (or bacon), cooked and crumbled
  • 1 30 oz / 1.9 lb bag frozen hash browns, thawed
  • 8 large eggs
  • 2 cups 0.5 lb shredded cheddar or Mexican blend cheese
  • 1 cup 0.25 lb shredded mozzarella cheese
  • 1 cup 0.24 L milk
  • ½ teaspoon garlic powder
  • ½ teaspoon onion powder
  • ½ teaspoon salt
  • ½ teaspoon black pepper
  • Chopped parsley for garnish optional

Instructions
 

Step 1: Preheat the Oven

  • Preheat your oven to 350°F (175°C). Grease a 9x13-inch baking dish with butter or cooking spray.

Step 2: Prepare the Hash Brown Layer

  • Spread the thawed hash browns evenly in the prepared baking dish.

Step 3: Add Sausage and Cheese

  • Sprinkle the crumbled breakfast sausage over the hash browns.
  • Top with 1 ½ cups of shredded cheddar and ½ cup of mozzarella cheese, reserving the rest for later.

Step 4: Make the Egg Mixture

  • In a large bowl, whisk together the eggs, milk, garlic powder, onion powder, salt, and black pepper until well combined.

Step 5: Assemble the Casserole

  • Pour the egg mixture evenly over the sausage, hash browns, and cheese.
  • Sprinkle the remaining cheese on top for an extra cheesy layer.

Step 6: Bake the Casserole

  • Bake for 45–50 minutes, or until the eggs are set and the top is golden brown.
  • Let the casserole cool for a few minutes before slicing.

Step 7: Serve and Enjoy

  • Garnish with chopped parsley, if desired, and serve warm.

Notes

  • Storage: Store leftovers in the fridge for up to 3 days. Reheat individual servings in the microwave or oven.
  • Freezer Option: Assemble the casserole and freeze unbaked. When ready to cook, bake directly from frozen at 350°F (175°C) for 60–70 minutes.
  • Vegetarian Option: Swap sausage with sautéed mushrooms, bell peppers, or spinach.
  • Make-Ahead Tip: Assemble the night before and refrigerate. Bake in the morning for a stress-free breakfast.
