  • 4 large sweetpotatoes, washed and sliced thinly (skin left on)
  • 1/4 cup olive oil
  • 1 tablespoon fresh thyme leaves
  • 1/2 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1 cup plain Greek yogurt
  • 1/4 cup parsley, chopped
  • 1 lemon, zest and juice
  • 2 garlic cloves, minced
  • Additional salt and black pepper, to taste


  • In a large mixing bowl, mix together sweetpotato slices, olive oil, thyme, 1/2 teaspoon salt and 1/2 teaspoon black pepper. Make sure each sweetpotato slice is coated well with the spices and oil.
  • In a 12-cupcake tin, stack enough sweetpotato slices in each muffin cup to fill each of the muffin cups.
  • Bake sweetpotato stacks in a 425°F oven for 45 minutes until potatoes are crispy, but well cooked. Rotate the pan halfway through cooking to ensure even baking.
  • While the sweetpotatoes are baking, mix together the Greek yogurt, parsley, lemon juice and zest and minced garlic. Season with salt and black pepper to your liking.
  • Serve each warm roasted sweetpotato stacker with a dollop of the herb yogurt sauce.
You can substitute 1 teaspoon of dried thyme for the 1 tablespoon of fresh thyme.
You can substitute 1/2 teaspoon of granulated garlic for the 2 fresh garlic cloves.
You can use whole fat, 2% or nonfat Greek yogurt.
You can easily make this dish vegan by opting for a plant-based plain yogurt.
