Alsatian Breakfast Sausage Casserole
Rise and shine! Sausage, Gruyère, apple, and rye come together for one heck of a sweet & savory breakfast egg casserole. Gruyère is a Swiss cheese with complex flavors that are creamy, fruity, and nutty. It pairs well with the sweet, yet tart, flavor of Honeycrisp apples.
Test Kitchen Tip
Worried about the casserole dripping over the sides? Set a baking sheet on the rack below or right underneath the baking dish.
Preheat oven to 375°. Coat a 7×11-inch baking dish with nonstick spray.
Brown sausage in a sauté pan over medium-high heat until almost fully cooked, 5 minutes.
Add onion and sauté until softened, 3 minutes. Transfer sausage mixture to a paper-towel-lined plate.
Whisk together eggs, milk, mustard, sage, and salt; season with pepper.
Arrange bread in bottom of prepared baking dish; top with apple, 1½ cups cheese, and sausage mixture. Pour egg mixture over sausage, taking care it doesn’t spill over, then top casserole with remaining ½ cup cheese.
Bake casserole until cheese is browned, eggs are set, and a thermometer inserted into the center registers 160°, about 45 minutes.
Brown the sausage, then transfer it to a paper-towel-lined plate to drain. It will finish cooking later.
This casserole is layered so that you get a taste of all the ingredients with every spoonful.
Begin adding the egg mixture a bit at a time, paying attention to how full the dish is so it doesn’t spill over.
