Ingredients

Breakfast Sausage: Ground pork sausage adds the perfect savory and spicy kick.
Eggs: Large eggs provide the fluffy structure for the casserole.
Cheddar Cheese: Sharp cheddar offers a bold flavor and excellent meltability.
Bread Cubes: Use slightly stale French or Italian bread for the best texture.
Whole Milk: This creates a rich and creamy custard base.
Dry Mustard: A classic addition that enhances the cheesiness of the dish.
Seasonings: Salt, black pepper, and a pinch of garlic powder.

Step-by-Step Instructions

Brown the Sausage: First, cook the sausage in a large skillet over medium heat until it is fully browned and crumbled.
Prepare the Dish: Meanwhile, grease a 9×13-inch baking dish and spread the bread cubes evenly across the bottom.
Layer the Ingredients: Sprinkle the cooked sausage and shredded cheese over the bread cubes.
Whisk the Base: In a separate bowl, whisk together the eggs, milk, and seasonings until well combined.
Pour and Soak: Pour the egg mixture over the layers and press down gently to ensure the bread is submerged.
Bake: Place the dish in a preheated oven at 350°F and bake for 40–45 minutes until the center is set.
Rest: Finally, let the casserole sit for five minutes before slicing and serving warm.

Pro Tips

To achieve the best results, try using a mix of mild and hot sausage to add extra complexity to the flavor. If you find the top is browning too quickly, simply cover the dish with foil for the last ten minutes of baking. Additionally, you can add sautéed bell peppers or onions for an extra boost of color and nutrition. Because the bread needs time to absorb the liquid, letting it sit for at least 30 minutes before baking is highly recommended.

Storage Instructions

You can store any leftovers in an airtight container in the refrigerator for up to four days. When you are ready to eat, reheat individual portions in the microwave for about 60 seconds. Alternatively, you can freeze the baked casserole for up to two months for a quick future meal. However, make sure to thaw it in the fridge overnight before reheating in the oven.
