Ingredients
Method
- Cook the sausage in a skillet over medium-high, breaking it apart, for 6 to 8 minutes until browned and cooked through; drain on paper towels.
- Whisk the eggs, milk, cream, mustard, salt, and pepper in a large bowl until smooth.
- Grease a 9x13-inch baking dish. Layer half the bread, half the sausage, 1 cup cheddar, and 1/4 cup Parmesan. Repeat layers, then pour the custard evenly over everything and press down gently.
- Cover and refrigerate for at least 8 hours or overnight.
- Preheat oven to 350°F (175°C). Bake uncovered for 45 to 50 minutes until puffed and golden, rest 10 minutes, top with green onions, and serve.
Notes
Plan ahead: the casserole must soak overnight, so do the assembly the night before. If the top browns too quickly, tent loosely with foil during the last 15 minutes of baking.
