How to Make Ultimate Christmas Morning Casserole
Preheat the Oven: Start by preheating your oven to 350 °F (175 °C) and greasing a 9×13-inch baking dish to ensure your casserole doesn t stick.
Brown the Sausage: In a skillet over medium heat, brown the ground breakfast sausage until it s fully cooked, then drain any excess grease. This will provide a savory base to your casserole.
Whisk the Eggs: In a large bowl, whisk together the eggs, milk, onion powder, garlic powder, salt, and pepper until everything is nicely combined, creating a rich mixture that binds the casserole together.
Layer the Hash Browns: Spread the thawed hash browns evenly in the greased baking dish; this will act as a delicious crispy base for your casserole.
Add Sausage and Cheese: Layer the cooked sausage on top of the hash browns and sprinkle the shredded cheddar cheese generously over them, adding that rich, gooey goodness.
Pour the Egg Mixture: Carefully pour the egg mixture evenly over the layers in the baking dish, ensuring all layers are coated well.
Bake the Casserole: Place the dish in the preheated oven and bake uncovered for 45-50 minutes, or until the center is set and the top is golden and bubbly.
Cool and Serve: Let the casserole cool for 5-10 minutes before slicing it into squares. For an extra touch, optionally garnish with fresh parsley or sliced green onions before serving warm.
Optional: Try serving with a side of fresh fruit for a vibrant contrast!
