Ingredients Equipment Method Notes

Ingredients
  

  • 1 lb ground pork sausage
  • 6 cups day-old white bread cubed into 1-inch pieces
  • 8 large eggs
  • 2 cups whole milk
  • 1/2 cup heavy cream
  • 1 tsp salt
  • 1/2 tsp black pepper
  • 1 tsp dry mustard powder
  • 2 cups shredded sharp cheddar cheese divided

Equipment

  • 1 9x13 inch Baking Dish
  • 1 Large Skillet
  • 1 Large Mixing Bowl

Instructions
 

  1. In a large skillet, cook the sausage over medium-high heat until browned, breaking it up with a spoon. Drain off any excess grease.
  2. Grease a 9x13-inch baking dish. Arrange the bread cubes in an even layer on the bottom. Sprinkle the cooked sausage over the bread, then top with 1 cup of the shredded cheese.
  3. In a large bowl, whisk together the eggs, milk, heavy cream, salt, pepper, and dry mustard until fully combined.
  4. Pour the egg mixture evenly over the layers in the baking dish. Top with the remaining 1 cup of cheese. Cover and refrigerate for at least 4 hours or overnight.
  5. Preheat the oven to 350°F (175°C). Uncover the casserole and bake for 45-55 minutes, until the center is set and the top is golden and bubbly.
  6. Let the casserole rest for 10 minutes before slicing and serving.

Notes

Tip 1: Using day-old bread is key to preventing a soggy casserole.
Tip 2: Don't skip the refrigeration time! This allows the bread to soak up the custard for the best texture.
Tip 3: Feel free to add sautéed vegetables like onions and bell peppers for extra flavor.
