Ingredients

  • For the potatoes:
  • butter or oil, to taste, for greasing the baking dish
  • 3 pounds (6-7 medium) Yukon Gold potatoes, thinly sliced into 1/8-inch rounds
  • 1/2 white or yellow onion, cut into slices
  • For the sauce:
  • 2 tablespoons salted butter
  • 1/4 cup all-purpose flour
  • 1 1/2 cups milk, may substitute unsweetened almond milk or skim
  • 1 (8-ounce) package sharp cheddar cheese, shredded
  • 1/2 teaspoon garlic powder
  • 3/4 teaspoon salt, plus more, to taste
  • freshly ground black pepper, to taste
  • For the topping:
  • 1/2 cup Gruyère cheese
  • 1/4 cup parmesan, grated
  • fresh parsley, optional, to taste, chopped, for garnish

Directions

Step 1 -Preheat the oven to 375 degrees F.

Step 2 -Coat a 2-quart square baking dish with the extra butter.

Step 3 -Add the potato slices to the prepared baking dish in three tight, slanted rows, leaving just enough space so the potatoes are slightly slanted.

Step 4 -Add the onion slices in between the rows and on top of the potatoes.

Step 5 -In a skillet over medium heat, melt the remaining 2 tablespoons of the butter.

Step 6 -Add about 1/4 of the flour to the melted butter and whisk to combine.

Step 7 -Slowly add in about 1/4 of the milk and vigorously whisk until no lumps remain.

Step 8 -Repeat adding the flour and the milk to the skillet, alternating between the 2 and whisking until smooth.

Step 9 -Bring the sauce mixture to a simmer.

Step 10 -Reduce the heat to low.

Step 11 -Add the cheddar cheese, the garlic powder, 3/4 teaspoon of the salt, and the pepper and stir to combine.

Step 12 -Taste the sauce and season it with the extra salt and the pepper, as needed.

Step 13 -Pour the sauce evenly over the potatoes and the onions to cover them completely.

Step 14 -Cover the pan with foil and bake for 45 minutes.

Step 15 -Remove the foil and sprinkle the potatoes with the Gruyère and the parmesan.

Step 16 -Bake until the potatoes are cooked through and the top is golden-brown, about 30-45 minutes.

Step 17 -Serve garnished with the parsley.
