Ingredients
To prepare this comforting casserole, you’ll need:
- 2 lbs ground breakfast sausage
- 2 lbs frozen hashbrown potatoes
- 2 cups shredded cheddar cheese
- 9 large eggs
- 2 cups milk
- 1 can diced green chilis, drained
- 1 tsp garlic powder
- ½ tsp onion powder
- Salt & pepper to taste

Step-by-Step Instructions
1. Preheat and Prep
Preheat your oven to 350°F (175°C). Grease a 9×13-inch casserole dish to prevent sticking.
2. Cook the Sausage
In a skillet over medium-high heat, brown the ground breakfast sausage until fully cooked. Remove from heat and set aside.
3. Prepare the Hashbrowns
Using the same skillet, cook the frozen hashbrown potatoes for 8–10 minutes until they are lightly browned and mostly thawed.
4. Assemble the Casserole
- Spread the cooked hashbrowns evenly in the greased casserole dish.
- Layer the browned sausage over the hashbrowns.
- Sprinkle the shredded cheddar cheese and drained green chilis on top.
5. Mix the Egg Mixture
In a large bowl, whisk together the eggs, milk, garlic powder, onion powder, salt, and pepper until well combined.
6. Combine and Bake
Pour the egg mixture evenly over the layered ingredients in the casserole dish. Bake uncovered for 35–40 minutes, or until the eggs are fully set and the top is golden brown.
Cooking Tips
- Make It Ahead: Assemble the casserole the night before, cover it, and refrigerate. In the morning, simply bake as directed.
- Customize It: Feel free to add vegetables like bell peppers or onions for extra flavor and nutrition.
- Cheese Variations: Try using different cheeses like mozzarella or pepper jack to change up the flavor profile.
