Description

A hearty and creamy Sausage & Brie Breakfast Casserole combining savory ground hot pork sausage, rich Brie, Parmesan cheese, and a custard of eggs, cream, and milk. This comforting casserole is perfect for a make-ahead breakfast or brunch, requiring an overnight chill and a final bake until set and golden.


Ingredients

Scale

Main Ingredients

  • 1 (8-oz) Brie round
  • 1 (1-lb) roll ground hot pork sausage
  • 6 slices white sandwich bread
  • 1 cup grated Parmesan cheese
  • 7 eggs, divided
  • 3 cups heavy whipping cream, divided
  • 2 cups milk
  • ¼ tsp salt
  • ¼ tsp black pepper
  • 1 tsp dry mustard


Instructions

  1. Prepare the Brie: Trim the rind from the Brie round, cut the cheese into cubes, and set aside for layering later.
  2. Cook the sausage: In a large skillet over medium heat, cook the ground hot pork sausage until it is no longer pink. Drain off any excess fat to avoid greasiness in the casserole.
  3. Assemble the base layer: Remove the crusts from the white bread slices and arrange the bread evenly in the bottom of a lightly greased 9×13-inch baking pan. Layer the cooked sausage over the bread, then sprinkle the Brie cubes and the grated Parmesan cheese evenly on top.
  4. Make the custard and refrigerate: In a large bowl, whisk together 5 of the eggs, 2 cups of heavy whipping cream, the 2 cups of milk, salt, black pepper, and dry mustard until well combined. Pour this mixture evenly over the layered ingredients in the pan. Cover the casserole tightly and refrigerate for 8 hours or overnight to allow the bread to soak up the custard.
  5. Preheat the oven: When ready to bake, preheat your oven to 350ºF (175ºC). Remove the casserole from the refrigerator and uncover it.
  6. Prepare the topping custard: Whisk together the remaining 2 eggs with 1 cup of heavy whipping cream. Pour this custard evenly over the chilled casserole for a rich, creamy finish.
  7. Bake: Place the casserole in the preheated oven and bake uncovered for 1 hour, or until the custard is fully set and the top is golden brown. The casserole should be firm to the touch and slightly puffed.

Notes

  • You can substitute the white sandwich bread with brioche or challah for a richer flavor and texture.
  • If you prefer a milder sausage, use mild pork sausage instead of hot.
  • Allowing the casserole to chill overnight lets the bread absorb the custard fully, resulting in a creamier texture.
  • This casserole can be assembled the night before, making it ideal for holiday or weekend breakfasts.
  • For easier cutting and serving, let the casserole sit for 10 minutes after baking.
  • Leftovers can be refrigerated and reheated in the oven or microwave.
