  • Muffin Tin
  • Mandolin or Sharp Knife
  • Mixing Bowls


  • 2 pounds Sweet Potatoes (see note)
  • 4 Tablespoons Unsalted Butter
  • 2 cloves Garlic, grated
  • 1 Tablespoon Fresh Thyme Leaves, plus a few more for sprinkling over top
  • ½ teaspoon Kosher Salt
  • ¼ teaspoon Black Pepper


  • Preheat oven to 400°F / 200°C.
  • Spray a 12-space regular-sized muffin pan with nonstick cooking spray or brush it with cooking oil. Set aside.
  • Melt butter in the microwave or on the stovetop. Whisk in grated garlic. Set aside to cool slightly.
  • Use a mandolin or very sharp knife to thinly slice the sweet potatoes. You can peel them first if you like, though it's not necessary. Aim for slices that are 1/16-inch thickness.
  • Place sweet potato slices in a large mixing bowl and pour butter over top. Add thyme leaves, salt, and black pepper.
  • Gently stir everything together, making sure that a small amount of butter gets between most of the slices.
  • Stack the sweet potato slices up in the prepared muffin tin, filling each section all the way up to the top or slightly higher.
  • Bake, uncovered, until sweet potatoes are golden brown on top and very tender, 30 to 40 minutes (this will vary depending on the thickness of the sweet potato slices).
  • Remove the muffin pan from the oven. If any of the sweet potato stacks have tipped over, use a spoon to gently nudge them back into place. Allow stacks to cool in the pan for 5 minutes before removing.
  • Serve warm.


This recipe was inspired by Southern Living’s Herbed Potato Stacks
Sweet Potatoes - This recipe works best if you pick out the sweet potatoes yourself with a mind for getting sweet potatoes that are fairly thin so that the slices will fit inside a muffin pan. There is no need to peel the sweet potatoes first, but you can if you’d like. 
Kosher Salt - I use Morton’s Kosher Salt to test recipes. If using table salt, reduce by about half. If using Diamond Kosher Salt, increase by about 25%. Everyone has their own preferences when it comes to salt, so be sure to taste and adjust as you go. 
Make-Ahead - You can make the stacks and bake them all the way through up to 3 days ahead. To reheat, place the stacks on a small parchment-lined sheet pan (or back in a muffin tin) and warm in a 400°F / 200°C oven until heated through, about 15 minutes.
