Ingredients
- 3 tablespoons olive oil or avocado oil
- 1 pound mushrooms sliced
- 4-6 garlic cloves pressed
- 1 medium onion thinly sliced
- 3 tablespoons gluten-free flour or 1/3 cup all-purpose flour
- 3/4 cup vegetable broth
- 1/4 cup soy sauce
- 2 cups milk of choice I used 2 %
- Kosher salt and ground pepper to taste
- 2 pounds russet or gold potatoes peeled and thinly sliced
- 1 cup grated Parmesan cheese divided
- 1 cup grated cheddar cheese
- Optional: freshly chopped parsley to garnish
Instructions
- Preheat the oven to 375F. Butter a 9” x 13” baking dish. Set aside.
- 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.
- Stir in the flour, then pour the broth, little by little, while stirring to remove any lumps.
- Add the soy sauce, milk, and salt and pepper.
- The gravy will be a bit salty, but don't worry, potatoes will absorb a lot and reduce the salty flavor.
- Cook until the sauce starts to thicken and coat the back of a spoon. Set aside.
- Drizzle a bit of oil and grease a 9x13 baking dish.
- 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.
- Repeat with layers and top with the cheddar cheese.
- 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.
- Allow the dish to cool for 15 minutes, then garnish with parsley, if desired.
