This recipe is for a 8x8 square baking dish and 3 cups of leftover stuffing (a 2 quart baking dish will work too). If you have about 4-5 cups of leftover stuffing then use a 9x13 baking dish, 8-10 large eggs and 3/4 cup milk. Baking time will also be about 10-15 additional minutes.
Pre-heat oven to 375°F. Grease an 8”x8” baking dish with the butter.
In a bowl, whisk together the milk, eggs, salt, and pepper.
Add stuffing in a single layer the the prepared baking dish. Sprinkle cheese over the stuffing.
Pour milk/egg mixture over the stuffing. Spread egg mixture evenly across stuffing. If the stuffing floats up, gently press it down into the egg mixture.
Bake for about 25-30 minutes or until golden and egg is set. Serve warm.
