Creamy Scalloped Potatoes With Thyme [Vegan]
- 3 tablespoons plus 1 teaspoon vegan butter, divided
- 3 tablespoons flour
- 1 teaspoon dry mustard
- 1 teaspoon kosher salt
- 2 cups non-dairy milk
- 1/2 teaspoon freshly ground black pepper
- 1 tablespoon chopped fresh thyme leaves
- 5 cups Yukon gold potatoes, peeled and thinly sliced crosswise
- 1 medium onion, diced
- Preheat oven to 375°F.
- Place a saucepan over medium heat and add vegan butter. Using a whisk, swirl the butter around in the pan until it's almost melted. Add the flour and stir briskly to incorporate the flour and butter. Sprinkle in the mustard and salt and continue to cook for one minute over medium heat. Whisk in the non-dairy milk and continue to stir, until the liquid comes to a rolling boil. Constantly stir and scrape the bottom of the pan while the sauce continues to cook and thicken, about 1 minute. Remove from heat and set aside.
- Spray an 8 by 8-inch baking dish with vegetable spray. Spoon 2-3 tablespoons of the béchamel (milk mixture) into the bottom of the dish.
- Sprinkle lightly with onions. Arrange potatoes in the bottom of the dish, overlapping as you go. Sprinkle with 1/3 of the onions. Pour 1/4 of the béchamel evenly over the potatoes. Continue layering in the same manner: Potatoes, onions, béchamel; potatoes, onions, béchamel. Finish with a layer of potatoes, topped with the last bit of béchamel.
- Place baking dish onto a rimmed baking sheet. Spray a piece of tin foil on one side with vegetable spray. Tent the foil over the potatoes and place into the hot oven. Set timer for 45 minutes.
