Instructions

  1. Preheat the oven to 375F. Butter a 9” x 13” baking dish. Set aside.
  2. In a rimmed pan, heat the oil. Add the mushrooms and saute for 5-7 minutes, stirring occasionally. Once the excess liquid has evaporated, stir in the onions and garlic and continue to saute for 3-4 minutes.
  3. Stir in the flour, then pour the broth, little by little, while stirring to remove any lumps.
  4. Add the soy sauce, milk, and salt and pepper.
  5. The gravy will be a bit salty, but don't worry, potatoes will absorb a lot and reduce the salty flavor.
  6. Cook until the sauce starts to thicken and coat the back of a spoon. Set aside.
  7. Drizzle a bit of oil and grease a 9x13 baking dish.
  8. Layer half of your potato slices and top with half of the mushroom gravy. Stir a bit to get the sauce through the potato slices. Sprinkle half of the grated parmesan cheese.
  9. Repeat with layers and top with the cheddar cheese.
  10. Cover the baking dish with aluminum foil and bake for 1 hour; Remove foil and continue to bake uncovered for about 25-30 minutes or until the top is golden-brown.
  11. Allow the dish to cool for 15 minutes, then garnish with parsley, if desired.
