Ingredients

  • 1 lb. diced ham
  • 1 yellow or white onion, diced finely
  • 4 tablespoons unsalted butter (1/4 cup)
  • 1 teaspoon garlic powder
  • 12 eggs
  • 2 cups heavy cream (can sub milk if you don't have cream)
  • teaspoons salt
  • 1/2 teaspoon pepper
  • 3 cups shredded cheddar cheese, divided
  • 3 cups frozen hash browns
  • 4 green onions, diced (plus extra for topping, if desired)

Instructions

  • Preheat oven to 350°F. Spray a 9"x13" baking dish with nonstick cooking spray and set aside.
  • In a medium saucepan or frying pan, add the 4 tablespoons of butter and diced onion. Cover and cook until onions are soft.
  • Once onions are soft, add the diced ham and simmer until browned. Once browned, add garlic powder and mix to combine.
    Remove from heat and set aside.
  • In a large mixing bowl, whisk together 12 eggs and the 2 cups of heavy cream.
  • Next, add in salt, pepper, 1 cup of the cheese (save remaining 2 cups of cheese for topping), hash browns, and green onions. Mix well.
  • Add ham and onion mixture to egg mixture and mix well.
  • Pour into prepared 9"x13" dish.
    Top with remaining 2 cups of cheese.
  • Cover with tinfoil and bake for 35 minutes covered, then remove tinfoil and bake for 20-25 more minutes until eggs are set.
  • If eggs start to get too brown, you can cover again with tinfoil until the eggs are set.
  • You will know the casserole is done, when the top is golden brown and the mixture is a little wobbly but not runny.
  • Once done, remove from oven and let rest for 10 minutes before serving. Can serve with additional diced green onions if desired. Enjoy!
