Ingredients

  • 1 lb gluten-free breakfast sausage, ham, or bacon (or vegetarian protein option)
  • 6 cups frozen hash browns, thawed and drained
  • 2 cups shredded cheddar cheese (or mozzarella, Gouda, or dairy-free cheese)
  • 6 green onions, chopped
  • 12 large eggs (room temperature)
  • 1½ cups milk (full-fat or plant-based alternative)
  • 1 teaspoon salt
  • ½ teaspoon black pepper

Instructions

  • Preheat and Prep
    • Preheat your oven to 375°F (190°C).
    • Grease a 9×13-inch baking dish with butter or non-stick spray.
  • Cook the Protein
    • In a skillet, cook the sausage or bacon until browned and slightly crispy. If using ham, dice it and set it aside. Drain any excess grease.
  • Assemble the Layers
    • Spread the thawed hash browns evenly across the bottom of the prepared baking dish.
    • Sprinkle the cooked protein over the hash browns.
    • Add a layer of shredded cheese, reserving about ½ cup for topping.
    • Scatter the green onions evenly over the cheese layer.
  • Prepare the Egg Mixture
    • In a large mixing bowl, whisk together the eggs, milk, salt, and pepper.
    • Pour the egg mixture evenly over the casserole, ensuring it coats all the ingredients.
  • Bake
    • Top the casserole with the remaining cheese.
    • Cover the dish with foil and bake for 30 minutes.
    • Remove the foil and bake for an additional 15 minutes, or until the cheese is melted and the casserole is golden brown.
  • Rest and Serve
    • Let the casserole rest for 10 minutes before slicing and serving. This allows it to set and makes serving easier.

Notes

  • Make Ahead Option: Assemble the casserole the night before, cover, and refrigerate. Bake fresh in the morning, adding 10 extra minutes to the cooking time.
  • Vegetarian Alternative: Skip the meat and load up on extra veggies like bell peppers, spinach, or mushrooms.
  • Dairy-Free Substitute: Use plant-based milk and vegan cheese for a dairy-free version.
  • Storage: Leftovers can be refrigerated in an airtight container for up to 4 days or frozen for up to 2 months.
