Equipment
- Large Skillet
- 13 x 9-Inch Baking Dish
- Large Bowl
- Whisk
- Foil
Ingredients
- 1 lb . bulk pork sausage – The star of the dish, providing rich, savory flavor.
- ½ cup diced onion – Adds a slight sweetness and savory depth to the casserole.
- 12 large slices white sandwich bread (crust trimmed and cubed) – The bread provides a soft base that soaks up all the flavors, creating a tender texture.
- 8 ounces cheddar cheese (grated, about 2 cups) – Sharp cheddar cheese gives the casserole a creamy, melty texture.
- 10 eggs – These help bind all the ingredients together and provide a fluffy texture.
- 3 cups whole milk – Adds creaminess and helps to create a custard-like base for the casserole.
- ½ teaspoon dry mustard – A secret ingredient that enhances the flavor with a little tang.
- 1 teaspoon kosher salt – To season the dish perfectly.
- ¼ teaspoon pepper – Adds a little kick and balances the flavors.
Instructions
- Start by browning the sausage and diced onion in a large skillet over medium-high heat. Stir occasionally, breaking up the sausage as it cooks, until the meat is no longer pink and the onions are tender, which should take about 7 minutes. Once cooked, drain any excess grease from the sausage mixture.
- Grease a 13 x 9-inch baking dish to prevent the casserole from sticking. Then, arrange the bread cubes in an even layer at the bottom of the dish. Spread the sausage and onion mixture evenly on top of the bread cubes, followed by a generous sprinkle of grated cheddar cheese.
- In a large bowl, whisk together the eggs, milk, dry mustard, kosher salt, and pepper. Make sure the mixture is fully combined and smooth, so the eggs soak into the bread evenly when poured over the casserole.
- Pour the egg mixture over the layered bread, sausage, and cheese. Gently press down on the bread with a spatula to ensure that all the bread cubes are soaked with the egg mixture. Cover the casserole tightly with foil and refrigerate it for 8 hours or overnight. This allows the flavors to meld together and gives the bread time to soak up the egg mixture for a fluffier texture.
