Description

This hearty breakfast casserole features savory turkey sausage, fluffy hash browns, sautéed vegetables, and melted cheddar cheese, all baked into a satisfying, customizable dish perfect for brunch or meal prep.


Ingredients

  • 1 tablespoon extra virgin olive oil
  • 1 pound turkey breakfast sausage
  • 1 medium yellow onion, diced
  • 1 red bell pepper, diced
  • 4 cups frozen diced hash browns, thawed
  • 1½ cups freshly shredded cheddar cheese
  • 2 tablespoons sliced chives
  • 8 large eggs
  • 1 cup whole milk
  • ½ teaspoon salt
  • ½ teaspoon black pepper

Instructions

  1. Preheat oven to 375°F (190°C). Grease a 9×13 inch baking dish and set aside.
  2. Heat olive oil in a large skillet over medium heat. Cook turkey sausage until browned, then remove and set aside.
  3. In the same skillet, sauté the diced onion and red bell pepper for about 5 minutes until softened.
  4. In a large bowl, combine thawed hash browns, cooked sausage, sautéed vegetables, shredded cheddar cheese, and chives.
  5. In a separate bowl, whisk together eggs, milk, salt, and pepper until smooth.
  6. Pour the egg mixture over the hash brown mixture and stir to combine.
  7. Transfer the mixture to the prepared baking dish, spreading it out evenly.
  8. Bake for 35–40 minutes, or until the eggs are set and the top is golden brown. A toothpick inserted in the center should come out clean.
  9. Let the casserole rest for 5 minutes before slicing and serving.

Notes

  • Can be made ahead and refrigerated overnight before baking.
  • Swap turkey sausage for pork sausage or vegetarian alternatives like mushrooms or zucchini.
  • Use any cheese you prefer—Monterey Jack, Gruyere, or Fontina all work well.
  • Store leftovers in the fridge for up to 3 days or freeze unbaked for later.
