Ingredients Equipment Method

Ingredients
  

  • 6 cups Cubed day-old bread French, sourdough, or sandwich bread work great
  • 1 lb Pork breakfast sausage cooked and crumbled
  • 1½ cups Shredded cheddar cheese
  • 6 Large eggs
  • 2 cups milk whole or 2% preferred for creaminess
  • 1 tbsp Dijon mustard
  • ½ tsp Salt
  • ¼ tsp Black pepper
  • Chopped green onions or a dash of paprika for garnish optional

Equipment

  • 9x13-inch baking dish
  • Large mixing bowl
  • Whisk
  • Spatula or spoon
  • Measuring cups and spoons
  • Skillet for browning sausage
  • Knife and cutting board for cubing bread and any optional toppings
  • Aluminum foil or plastic wrap if chilling before baking
  • Oven mitts

Method
 

  1. Prepare the Baking Dish
    Lightly grease a 9x13 inch baking dish. Spread your cubed bread evenly across the bottom.
  2. Add the Layers
    Sprinkle the cooked and crumbled sausage over the bread. Then, scatter the shredded cheddar cheese on top.
  3. Whisk the Egg Mixture
    In a large mixing bowl, mix together the eggs, milk, Dijon mustard, salt and black pepper until smooth.
  4. Pour and Soak
    Carefully pour the egg mixture over the sausage, cheese, and bread. Press down gently with a spatula so the bread absorbs the liquid.
  5. Chill (Optional, but Recommended)
    Cover and refrigerate for at least 30 minutes or overnight. This allows the flavors to blend and the bread to soak up the mixture for a creamier texture.
  6. Bake
    Preheat your oven to 350°F (175°C). Bake uncovered for 45–50 minutes, or until the top is golden and the center is set.
  7. Cool and Serve
    Let the casserole cool for 5–10 minutes before slicing. Garnish with green onions or paprika if desired.
