  1. Preheat the oven to 400 degrees.
  2. In a greased casserole dish, arrange the sliced potatoes, carrots, and mushrooms overlapping. Season the vegetables with salt and pepper.
  3. In a small sauce pot over medium low heat, melt the butter. Once melted, add the flour and a pinch of salt. Stir constantly for 1 minute. Add the milk and continue to stir occasionally until it begins to thicken. Once milk mixture has thickened, remove from the heat, mix in the cheese and allow to melt.
  4. Pour the cheese sauce over the potatoes, carrots, and mushrooms. Cover the dish with a sheet of aluminum foil and place in oven. Bake until the gratin until the vegetables are tender and sauce is bubbling, about 40-60 minutes.
