  • 2 medium sweet potatoes peeled and thinly sliced
  • 2 medium Yukon Gold or russet potatoes peeled and thinly sliced
  • 1.5 cups heavy cream
  • 3 cloves garlic minced
  • 1 teaspoon fresh thyme leaves

  • 1 cup shredded mature cheddar cheese
  • Salt and freshly ground black pepper to taste
  • 2 tablespoons butter for greasing the baking dish

  2. In a saucepan over medium heat, combine the heavy cream, garlic, thyme, smoked paprika, nutmeg, salt, and pepper. Heat until warm (do not boil) to infuse the flavors, then remove from the heat.

  3. Stir in ⅔’s of the cheddar cheese.

  5. Pour over the warmed cream, ensuring it seeps into all the layers.
  6. Cover the skillet with foil and bake for 45 minutes. Remove the foil, sprinkle the reserved cheese over the top, and bake for an additional 20-25 minutes, or until the top is golden brown and the vegetables are tender when pierced with a knife.
