Description

This hearty Potato and Egg Casserole combines layers of thinly sliced potatoes, savory sausage, onions, and cheddar cheese, all bound together with a flavorful egg and milk mixture. Baked to golden perfection, this dish makes for a satisfying breakfast, brunch, or comforting dinner that serves six.


Ingredients

Main Ingredients

  • 4 large potatoes, peeled and thinly sliced
  • 6 large eggs
  • 1 cup milk
  • 1 cup shredded cheddar cheese
  • 1/2 cup diced onion
  • 1/2 cup cooked turkey or beef sausage, crumbled

Seasonings and Others

  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • 1 tablespoon butter (for greasing)


Instructions

  1. Preheat and Prepare: Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish with butter to prevent sticking and add richness to the casserole base.
  2. First Layer: Arrange half of the thinly sliced potatoes evenly in the baking dish. Sprinkle half of the diced onions, shredded cheddar cheese, and crumbled sausage evenly over the potatoes to create a flavorful base layer.
  3. Repeat Layers: Repeat the layering with the remaining potatoes, onions, cheese, and sausage to build a stacked casserole packed with taste and texture.
  4. Mix Egg Mixture: In a bowl, whisk together the eggs, milk, garlic powder, salt, and black pepper until fully combined. This mixture binds all the ingredients together during baking.
  5. Pour Egg Mixture: Carefully pour the egg and milk mixture evenly over the layered casserole, ensuring it seeps between the layers for even cooking and flavor distribution.
  6. Cover and Bake: Cover the baking dish with aluminum foil to trap moisture and bake for 40 minutes, allowing the potatoes to soften and the casserole to set.
  7. Uncover and Finish Baking: Remove the foil and bake uncovered for an additional 15 minutes. This step browns the top, creating a golden crust and ensuring the center is cooked through; verify doneness by inserting a knife in the middle—it should come out clean.
  8. Rest and Serve: Let the casserole cool for 5 minutes before slicing and serving. This resting time helps the casserole to firm up, making it easier to serve.

Notes

  • For a vegetarian version, substitute the sausage with sautéed mushrooms or plant-based sausage.
  • If you prefer a richer casserole, use half-and-half or heavy cream instead of milk.
  • You can prepare this casserole the night before and refrigerate it before baking to save time in the morning.
  • Adding fresh herbs like parsley or chives on top after baking adds a fresh flavor and a pop of color.
  • Ensure potatoes are sliced evenly for consistent cooking throughout.
