Ingredients Needed
Ingredients List
For the Casserole Base :
- 1 package (30 oz) frozen shredded hash browns, thawed
- 2 cups cheddar cheese, shredded
For the Filling :
- 8 eggs (room temperature)
- 1 1/2 tsp salt
- 1/4 tsp garlic powder
- 1 lb turkey or chicken sausage
- 1 tsp black pepper
- 1 1/2 cups whole milk or heavy cream
Ingredient Notes
Thawed hash browns are essential to prevent excess moisture in the casserole. Eggs act as the binding base, while milk or cream adds richness. Fully cooked turkey or chicken sausage ensures even flavor throughout, and cheddar cheese provides that classic melty finish.
Ingredient Substitutions
- Use plant-based sausage for a vegetarian version
- Swap cheddar with Monterey Jack, pepper jack, or a blend
- Use half-and-half or 2% milk instead of cream
- Add vegetables like mushrooms, peppers, or spinach for extra flavor
How to Make It (Step-by-Step)
Step 1: Preheat Oven and Prepare Baking Dish
Preheat your oven to 375°F (190°C) and spray a 9 x 13-inch baking dish with non-stick cooking spray.
Step 2: Brown the Sausage
In a skillet over medium heat, cook the turkey or chicken sausage, breaking it into small pieces as it browns. Once fully cooked, drain excess grease and set aside.
Step 3: Make the Egg Mixture
In a large bowl, whisk together eggs, milk or cream, salt, black pepper, and garlic powder until well combined.
Step 4: Assemble the Casserole
Spread the thawed hash browns evenly in the baking dish. Add the cooked sausage, sprinkle shredded cheddar cheese, then pour the egg mixture evenly over everything.
Step 5: Bake the Casserole
Cover with foil and bake for 40 minutes. Remove the foil and bake for another 20 minutes until the eggs are set and the top is lightly browned. Let rest for 5 minutes before slicing.
Step 6: Serve
Slice into portions and serve warm. Optional: top with hot sauce or salsa.
