This easy Sausage Hashbrown Casserole is loaded with savory breakfast sausage, golden hash browns, cheddar cheese, green chiles, and fluffy baked eggs. It is a hearty make-ahead breakfast that is perfect for family mornings, brunches, holidays, and potlucks.
Preheat the oven to 350°F and lightly grease a 9×13-inch casserole dish.
Place the breakfast sausage in a large skillet over medium-high heat. Cook, breaking the sausage into crumbles as it browns, until completely cooked through. Remove it from the skillet and set aside.
Add the frozen hash browns to the same skillet. Cook for 8-10 minutes, stirring occasionally, until mostly thawed and beginning to turn lightly golden.
Spread the hash browns evenly across the bottom of the prepared casserole dish.
Spoon the cooked sausage evenly over the potato layer.
Sprinkle the shredded cheddar cheese over the sausage, then distribute the drained green chiles evenly over the cheese.
In a large bowl, whisk together the eggs, milk, garlic powder, onion powder, salt, and pepper until thoroughly combined.
Slowly pour the egg mixture evenly over the casserole, allowing it to settle around the sausage, cheese, and potatoes.
Bake uncovered for 35-40 minutes, or until the center is completely set and the eggs are cooked through.
Remove the casserole from the oven and let it rest for 5-10 minutes before slicing and serving.
Notes
For the best texture, lightly brown the hash browns before assembling the casserole. This removes excess moisture and helps create a firmer, more flavorful potato layer instead of a soggy bottom.
