Ingredients:
- 1 lb. (454 g) Italian Sausage, cooked
- 1 medium yellow onion, chopped and sautéed in sausage grease
- 7 large eggs
- 1/2 cup (120 ml) milk
- 1 bag (20 oz. / 567 g) frozen diced hash browns
- 8 oz. (227 g) brick of mild cheddar cheese, grated
- Salt and pepper, to taste
Directions:
Preheat your oven to 350°F (175°C) and generously spray a medium casserole dish (we recommend using a 9×13-inch dish) with non-stick spray. Set it aside.
Cook the Italian sausage in a skillet until browned and fully cooked. Remove from heat and set aside.
In a large mixing bowl, combine the cooked sausage, sautéed onions, eggs, milk, frozen diced hash browns, and most of the grated cheddar cheese (reserving about a cup for topping). Stir everything together until well mixed.
Pour the mixture into the prepared casserole dish, spreading it evenly. Sprinkle the reserved grated cheese on top, creating a tantalizing golden crust.
Bake the casserole in the preheated oven for approximately 35 minutes, or until the center is set and the top is lightly golden.
Remove the casserole from the oven and allow it to rest for 15-20 minutes. This resting time allows the flavors to meld together and ensures easy serving.
Serve this Cheesy Potato Breakfast Casserole with love and watch as your loved ones savor every scrumptious bite. It pairs perfectly with a side of fresh fruit or a steaming cup of coffee for the ultimate breakfast experience.

- Feel free to customize your casserole by adding your favorite ingredients such as diced bell peppers, chopped spinach, or diced tomatoes.
