Preheat oven to 450 degrees. Shape the pie crust into a 9-inch tart pan, trimming the excess from the edges. Line with foil and add pie weights. Bake the crust for 10 minutes. Remove the foil and weights and bake for another 5 minutes until lightly golden brown. Remove from oven and let cool. Reduce the oven to 400 degrees.
Meanwhile, heat a skillet over medium heat. Peel, core, and chop the apple into bite-size pieces. Cut the sausage into bite-size pieces. Add the butter, apples, and sausage to the skillet. Saute for 10 minutes or until the apples are slightly softened. Meanwhile, whisk together the eggs, heavy cream.
Whisk together the eggs, heavy cream, and pepper. Place the tart pan on a sheet pan. (This will catch any spillover while baking.) Spread the apples and sausage in the bottom of the pie crust. Top with the shredded cheese. Pour the egg mixture over the top. Be careful not to overfill the crust. Bake the quiche at 400 degrees for 25-30 minutes until eggs are set. Remove from oven and let sit for 10 minutes.
Slice and serve warm or at room temperature.
Use a 9-inch tart pan for this recipe.
Be careful not to overfill the tart pan with the egg mixture. There may be some leftover egg mixture that doesn't fit in the pan.
