Sausage and Cheddar Breakfast Casserole
- 1 tbsp. unsalted butter, for greasing
- 6 slices white bread
- 1 lb. bulk breakfast sausage, casing removed
- 10 oz. grated cheddar cheese
- 2 cups milk
- 1/2 tsp. dry mustard
- 6 eggs, lightly beaten
- Kosher salt and freshly ground black pepper, to taste
Heat oven to 350°. Grease a 9" x 13" baking dish with butter. Lay bread slices, overlapping slightly, over bottom of dish. Heat a 12" skillet over medium-high heat. Add sausage; cook, stirring and breaking up meat into large crumbles until browned, 5–7 minutes. Using a slotted spoon, transfer sausage to dish and arrange over bread.
Sprinkle half the cheese over sausage. Whisk milk, mustard, eggs, salt, and pepper in a bowl; pour milk mixture over sausage and sprinkle with remaining cheese. Cover dish with foil and set aside 10 minutes. Bake, covered, until eggs are set, about 30 minutes. Turn oven to broil. Uncover casserole and cook until cheese is browned, about 3 minutes.
