Notes on Quality

Step-by-Step Instructions

1. Preheat and Prep:
Preheat oven to 375°F (190°C). Grease a 9×13-inch baking dish with butter or cooking spray.

2. Cook the Sausage:
Brown the sausage in a skillet over medium heat, breaking it apart. Once fully cooked, drain the excess grease.

3. Layer the Hashbrowns:
Spread the thawed hashbrowns evenly in the baking dish this forms the crispy base.

4. Add Sausage and Cheese:
Top the hashbrowns with cooked sausage. Sprinkle cheddar and mozzarella cheeses evenly over everything.

5. Mix the Eggs:
In a large bowl, whisk the eggs, milk, salt, pepper, garlic powder, and onion powder until smooth.

6. Assemble the Casserole:
Pour the egg mixture evenly over the layered ingredients, making sure it seeps through the layers.

7. Bake:
Bake uncovered for 40-45 minutes, or until the top is golden and the center is just set.

8. Rest & Serve:
Let it rest for 5-10 minutes before slicing. This helps it hold together when serving.

Expert Tips & Tricks

Best Practices

• Pat those hashbrowns dry! Excess moisture can make the casserole watery.
• Use freshly grated cheese for the best melt and texture.
• Let it cool before slicing to keep clean layers and avoid a runny center.

Common Mistakes

• Overbaking: The eggs will dry out. Pull it once the center is barely set.
• Not thawing hashbrowns: Frozen potatoes won't bake evenly.

Time-Saving Tips

• Make it ahead: Assemble the night before, refrigerate, and bake in the morning.
• Use pre-cooked sausage crumbles for even faster prep.
