Prepare this hearty, savory breakfast strata the night before for a warm, delicious start to your holiday morning. This recipe is perfect for feeding a crowd and removes stress from your Christmas brunch.

Ingredients

Scale
  • 1 loaf sourdough bread, cubed
  • 1 pound pork sausage, cooked and drained
  • 1 cup diced ham or Canadian bacon
  • 1 1/2 cups shredded Gruyère cheese
  • 1 cup shredded sharp cheddar cheese
  • 8 large eggs
  • 2 cups whole milk
  • 1 cup heavy cream
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1/2 teaspoon dry mustard powder

Instructions

  1. Grease a 9×13 inch baking dish. Arrange the cubed sourdough bread evenly in the bottom of the dish.
  2. Sprinkle the cooked sausage, diced ham, Gruyère cheese, and cheddar cheese over the bread layer.
  3. In a large bowl, whisk together the eggs, milk, heavy cream, salt, pepper, and dry mustard powder until fully combined. This creates your flavorful custard.
  4. Slowly pour the egg mixture evenly over the bread and meat layers in the baking dish. Gently press down on the bread to help it absorb the liquid.
  5. Cover the baking dish tightly with plastic wrap. Refrigerate for at least 8 hours, or preferably overnight. This is the key to your stress-free Christmas morning.
  6. When ready to bake, preheat your oven to 350 degrees Fahrenheit. Remove the plastic wrap.
  7. Bake uncovered for 45 to 55 minutes, or until the casserole is puffed, golden brown, and a knife inserted near the center comes out clean.
  8. Let the casserole rest for 10 minutes before slicing and serving this easy holiday breakfast.

Notes

  • For an even easier morning, you can assemble the entire casserole, cover it, and freeze it for up to one month. Thaw overnight in the refrigerator before baking.
  • If you need to bake immediately, let the assembled casserole sit at room temperature for 30 minutes before placing it in the preheated oven, then increase the baking time by about 5-10 minutes.
  • This recipe feeds 8 to 10 people, making it ideal for feeding a crowd at your Christmas brunch menu planning.
