Preheat the oven to 350°F (175°C) and grease a 9×13-inch baking dish.
Cook the sausage in a skillet, breaking it into small pieces. Drain the grease once the meat is browned.
Cut the pancakes into quarters and arrange them in the baking dish. Scatter the sausage and cheddar between the pieces.
Whisk the eggs, milk, maple syrup, vanilla, cinnamon, and salt. Pour the mixture evenly over the pancakes.
Bake for 40 to 45 minutes, until the center is set and the upper pancake edges are lightly browned.
Rest for 10 minutes before slicing. Serve with maple syrup or cool completely before freezing portions.
