Essential Ingredients for Perfect sausage hashbrown breakfast casserole

To make this spicy, creamy, cheesy casserole, you’ll need a few pantry and fridge staples. Here’s what makes this dish special:

Spicy Breakfast Sausage: The foundation of the dish! Use your favorite bulk sausage—hot or mild depending on your heat preference. You can also swap in turkey sausage for a lighter option.
Frozen Hash Browns: These create that crispy, golden base we all love. Feel free to use shredded or diced hash browns.
Cheddar Cheese: Sharp cheddar works wonderfully to add melty goodness. For a twist, try pepper jack or gouda.
Green Chiles: These optional peppers give the casserole a subtle zing. If you’re not a fan, you can skip them or use diced bell peppers instead.

sausage hashbrown breakfast casserole Ingredients

Cooking spray
2 pounds bulk spicy breakfast sausage
2 pounds frozen hash brown potatoes
2 cups shredded Cheddar cheese
1 (7 ounce) can green chile peppers (optional)

How to Make sausage hashbrown breakfast casserole

Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish with cooking spray.
In a skillet over medium heat, cook the sausage, breaking it into crumbles until fully cooked and no longer pink. This should take about 5-7 minutes. Drain and set aside.
Using the same skillet, cook the hash browns over medium heat in the sausage drippings. Stir occasionally until they’re golden and slightly crispy, about 8 minutes. Then spread the hash browns evenly into the prepared baking dish.
Layer the cooked sausage evenly over the hash browns, followed by the cheese. If using green chiles, sprinkle them on top.
In a large mixing bowl, whisk together the eggs, milk, salt, pepper, onion powder, and garlic powder. Pour this mixture evenly over the layers.
Bake uncovered for 35-40 minutes, or until bubbly and golden brown on top. Let it cool slightly before serving.

Make-Ahead Tip: You can assemble this casserole the night before! Just cover it tightly and refrigerate. Bake it fresh in the morning—add an extra 5-7 minutes to account for the chill.

Make it gluten-free: Double-check that your sausage and seasonings are certified gluten-free.
Reheating: Warm leftovers in the oven at 350°F for 10-15 minutes, or microwave individual portions.
