Description
A delicious breakfast casserole with sausage, cheese, and bread, perfect for family gatherings or brunch.
Ingredients
Scale
- 1 lb ground breakfast sausage
- 1 large yellow onion, chopped (about 200-250g)
- 1 loaf sourdough or country-style bread, cut into 1-inch cubes (about 8–9 cups)
- 2 cups shredded Gruyère cheese (about 8 oz / 225g)
- 1/2 cup grated Parmesan cheese (50g)
- 2 tablespoons fresh parsley, chopped (30ml)
- 8 large eggs
- 2 cups whole milk (480ml)
- 1 cup heavy cream (240ml)
- 1 tablespoon Dijon mustard (15ml)
- 1 teaspoon salt (5g)
- 1/2 teaspoon freshly ground black pepper (2g)
- 1/4 teaspoon ground nutmeg (1g)
Instructions
- In a large skillet over medium-high heat, cook the ground breakfast sausage, breaking it apart with a spoon, until browned. Add the chopped onion and cook for another 5-7 minutes until softened. Drain any excess grease.
- In a large bowl, combine the cubed bread, the cooked sausage and onion mixture, 1 1/2 cups of the Gruyère cheese, and the Parmesan cheese. Toss gently to combine. Transfer the mixture to a greased 9×13-inch baking dish and spread in an even layer.
- In the same large bowl, whisk together the eggs, whole milk, heavy cream, Dijon mustard, salt, pepper, and nutmeg until smooth and fully combined.
- Pour the egg custard evenly over the bread mixture in the baking dish. Gently press down on the bread to help it absorb the liquid. Sprinkle the remaining 1/2 cup of Gruyère cheese on top. Cover tightly with plastic wrap or foil and refrigerate for at least 8 hours, or overnight.
- The next morning, remove the casserole from the refrigerator 30 minutes before baking. Preheat your oven to 350°F (175°C). Uncover the dish and bake for 50-60 minutes, or until the casserole is puffed, golden brown, and a knife inserted into the center comes out clean.
- Let the casserole rest for 10 minutes before slicing. Garnish with fresh parsley and serve warm.
Notes
- Can be prepared the night before for easy assembly in the morning.
