Ingredients
Scale
Potato Layer
- 4 large potatoes, peeled and thinly sliced
- 1/2 cup diced onion
- 1 cup shredded cheddar cheese
- 1/2 cup cooked turkey or beef sausage, crumbled
Egg Mixture
- 6 large eggs
- 1 cup milk
- 1/2 teaspoon garlic powder
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
Other
- 1 tablespoon butter (for greasing)
Instructions
- Preheat and grease: Preheat the oven to 375°F (190°C). Grease a 9×13-inch baking dish with butter to prevent sticking and ensure easy serving.
- Layer potatoes and fillings: Arrange half of the thinly sliced potatoes evenly in the bottom of the prepared baking dish. Sprinkle half of the diced onions, shredded cheddar cheese, and crumbled cooked sausage on top. This layering builds flavor and texture throughout the casserole.
- Repeat layering: Add the remaining potatoes to create a second layer, then top again with the rest of the onions, cheese, and sausage to complete the layering process.
- Mix egg custard: In a medium bowl, whisk together the six large eggs, milk, garlic powder, salt, and black pepper until well combined. This mixture will soak the potatoes and fillings, binding everything as it bakes.
- Pour custard over layers: Carefully pour the egg mixture evenly over the layered potatoes and sausage in the baking dish, allowing it to seep down and fill gaps.
- Bake covered: Cover the casserole dish with foil and bake in the preheated oven for 40 minutes. This initial baking steams and cooks the potatoes gently.
- Bake uncovered: Remove the foil and continue baking for an additional 15 minutes. This step allows the top to become golden brown and ensures the casserole is fully cooked through. Check doneness by inserting a knife in the center—if it comes out clean, the casserole is ready.
- Cool and serve: Let the casserole cool for about 5 minutes before slicing. This resting time helps the casserole set for easier serving and better texture.
Notes
- You can substitute turkey or beef sausage with vegetarian sausage or cooked bacon as desired.
- Thinly slicing the potatoes ensures even cooking; use a mandoline slicer if available.
- If desired, add chopped green peppers or mushrooms for extra flavor and texture.
- Leftovers can be refrigerated for up to 3 days and reheated in the oven or microwave.
- For a creamier texture, use half-and-half or heavy cream instead of milk.
