Ingredients

  • 3 lbs sweet potatoes, peeled and sliced thinly
  • ¼ cup unsalted butter
  • 6 garlic cloves, minced
  • 2 tablespoon fresh sage, chopped
  • 1 tablespoon cornstarch
  • 1 cup heavy cream
  • 1 cup whole milk
  • 1 teaspoon sea salt
  • ¼ teaspoon black pepper
  • 2 cups shredded Gruyère cheese
  • ¼ cup freshly grated Parmesan cheese

Instructions

  • Preheat the oven to 400°F. Peel and finely slice the sweet potatoes into ⅛ inch rounds and set aside.
  • Heat the butter over medium heat in a saucepan until melted. Add the garlic and sage and cook for 30 seconds. Whisk in the cornstarch until combined.
  • Add the cream, milk, salt and pepper. Heat until a soft boil occurs, about 10 minutes. Remove from heat and stir in the Gruyère and Parmesan cheese.
  • In a 9x13 baking dish, arrange the sweet potato rounds in rows and pour the cheese sauce over top.
  • Cover the baking dish with aluminum foil and bake for 35 minutes. Remove the foil and bake another 10 minutes or until the cheese is golden. Serve warm.

Notes

  • Select sweet potatoes that are firm and free from blemishes. You can use either orange or white-fleshed sweet potatoes, depending on your preference.
  • Slice the sweet potatoes uniformly to ensure even cooking. A mandoline slicer can be helpful for achieving consistent thickness.
  • Cover the dish with foil or a lid during the initial baking to trap steam and help the sweet potatoes cook through. Remove the cover during the last part of baking for a golden top.
  • Allow the dish to rest for a few minutes after baking. This helps the flavors meld and makes it easier to serve.
