Instructions

Preheat and Prepare Dish: Preheat the oven to 375°F and grease a 9×13-inch baking dish to prevent sticking.
Arrange Hash Browns: Spread the thawed and drained shredded hash browns evenly into the prepared baking dish, creating a base layer.
Sauté Vegetables: In a skillet over medium heat, add a small amount of butter or oil and sauté the diced onion and bell pepper for 3 to 4 minutes until softened and fragrant.
Mix Egg Mixture: In a large bowl, whisk together the eggs, whole milk, melted butter, salt, black pepper, and garlic powder until fully combined and smooth.
Combine Ingredients: Stir the sautéed onions and bell peppers into the egg mixture, then add shredded cheddar, mozzarella cheeses, and the optional diced ham or sausage if using. Mix well to incorporate all ingredients.
Assemble Casserole: Pour the egg and cheese mixture evenly over the hash browns in the baking dish. Gently press down to ensure the mixture is evenly distributed and the hash browns are coated.
Bake: Place the dish in the preheated oven and bake for 40 to 45 minutes or until the center is set and the top is lightly golden brown, indicating it is fully cooked.
Rest and Serve: Remove from oven and let the casserole rest for 5 to 10 minutes to firm up before slicing. Serve warm and enjoy.

Notes

Ensure the hash browns are fully thawed and well-drained to avoid excess moisture in the casserole.
For variety, you can substitute the ham or sausage with cooked bacon, turkey sausage, or sautéed mushrooms.
Leftovers refrigerate well for up to 4 days and reheat easily in the microwave or oven.
