How to Make Hashbrown Breakfast Casserole

This hashbrown breakfast casserole comes together with simple steps and bakes into a warm, golden dish that’s perfect for breakfast or brunch.

1. Preheat oven to 375°F (190°C).
2. Spray a 9×13-inch baking dish generously with non-stick spray.
3. Thaw the frozen shredded hashbrowns.
4. Squeeze out excess liquid from the thawed hashbrowns using a clean kitchen towel or paper towels.
5. In a skillet over medium heat, cook 1 lb pork sausage, breaking it into small pieces, until browned and no pink remains.
6. Drain excess grease from the cooked sausage.
7. In a large bowl, whisk together 8 eggs, 1 1/2 cups milk or cream, 1 1/2 tsp salt, 1 tsp black pepper, and 1/4 tsp garlic powder until fully combined.
8. Spread the thawed, drained hashbrowns evenly in the prepared baking dish.
9. Sprinkle the browned sausage evenly over the hashbrowns.
10. Scatter 2 cups shredded cheddar cheese over the sausage.
11. Pour the egg mixture evenly over the casserole, making sure it seeps to the edges.
12. Cover the dish tightly with aluminum foil.
13. Bake covered for 40 minutes.
14. Remove the foil and bake uncovered for 20 minutes more, until the casserole is set in the center and the top is lightly golden brown.
15. Let the casserole rest 5 to 10 minutes before slicing and serving.

For safe cooking, make sure the casserole is fully set in the center before serving.

Tips for the Best Hashbrown Breakfast Casserole

• Let it rest before slicing: Allow the casserole to sit for 5 to 10 minutes after baking. This helps it set properly and makes slicing easier, similar to what we do in our
  crustless cottage cheese zucchini quiche.
• Drain the hash browns well: After thawing, squeeze out as much moisture as possible using a clean kitchen towel or paper towels. This helps prevent a soggy casserole and gives you that golden, slightly crisp top.
• Fully cook the sausage: Brown the sausage completely before adding it to the casserole, then drain the excess fat. This keeps the texture cleaner and avoids greasy spots.
• Bake covered, then uncovered: Keep the casserole covered for the first 40 minutes, then uncover for the final 20 minutes so the top can brown and crisp up—just like we do in our
  healthier broccoli chicken casserole.

Swaps and Variations

• This hashbrown breakfast casserole is easy to adapt depending on what you have on hand.
• Sausage options: Swap pork sausage for turkey or chicken sausage for a lighter version. Crumbled bacon also works well. For a meatless option, use plant-based sausage or sautéed mushrooms and bell peppers.
• Milk or cream: Whole milk or heavy cream gives the richest texture, but half-and-half or 2% milk works too. For a dairy-free option, use unsweetened almond or oat milk (the result will be slightly less creamy).
• Cheese variations: Cheddar is classic, but you can use Monterey Jack, pepper jack, Swiss, or a Mexican blend depending on your taste.
• Hash browns: Frozen shredded hash browns are the easiest option. If using fresh potatoes, grate them and squeeze out as much moisture as possible before using.
• Eggs: Eggs are essential for structure and texture, so they should not be replaced in this recipe.

Storage, Make-Ahead, and Reheating

This hashbrown breakfast casserole works very well for meal prep and leftovers.

• Make ahead: Assemble the casserole, cover tightly, and refrigerate for up to 24 hours before baking.
• Baking from cold: If baking straight from the fridge, cook for 65–80 minutes total. Let it sit at room temperature for 15–30 minutes before baking if possible for more even cooking.
• Refrigeration: Store leftovers in an airtight container in the fridge for up to 4 days.
• Freezing: Freeze the whole casserole before baking or store individual portions. Wrap well to prevent freezer burn.
• Reheating: Warm in the oven at 350°F (175°C) for about 20 minutes, or microwave individual portions for 1–2 minutes until heated through.

Is Hashbrown Breakfast Casserole Healthy?

This hashbrown breakfast casserole can be part of a balanced meal when enjoyed in moderation.

It provides protein from eggs and sausage, along with energy from potatoes and dairy. While it’s rich and satisfying, it’s best paired with lighter sides like fresh fruit or a simple salad to keep the meal balanced.

To make it lighter, you can use turkey sausage, reduce the amount of cheese, or swap heavy cream for milk. Small adjustments like these can help tailor the dish to your preferences while keeping its comforting flavor.
