Golden-brown, perfectly sliced sweet potatoes roasted with a flavorful herb butter that creates crispy edges and tender insides. This easy and elegant side dish is perfect for any occasion.

Ingredients

Scale
  • 4 medium sweet potatoes (68 inches long)
  • 4 tablespoons (60g) unsalted butter, softened
  • 1 teaspoon fresh rosemary, finely chopped
  • 1 teaspoon fresh thyme, finely chopped
  • 1 tablespoon fresh parsley, chopped
  • 2 cloves garlic, minced
  • Salt and pepper to taste
  • 1 tablespoon olive oil
  • ½ teaspoon lemon zest (optional)

Instructions

  1. Preheat the oven to 425°F (220°C).
  2. Rinse and dry the sweet potatoes. Place one on a cutting board and make thin slices about ¼ inch (6 mm) apart, slicing almost all the way through but leaving the bottom intact so the potato fans out like a book. Use chopsticks or wooden spoons on either side to prevent cutting through completely.
  3. In a small bowl, mix softened butter, rosemary, thyme, parsley, minced garlic, lemon zest (if using), salt, and pepper until well combined.
  4. Lightly brush the sweet potatoes all over with olive oil. Gently spread the herb butter between each slice using a spoon or fingers, making sure the slices fan open to hold the butter.
  5. Sprinkle sea salt flakes and freshly ground pepper over the top.
  6. Place the potatoes on a baking sheet and bake for 35-40 minutes. Halfway through baking (around 20 minutes), baste the potatoes with more herb butter from the pan or any remaining mixture.
  7. Check for doneness by piercing with a fork; potatoes should be tender inside and crispy at the edges. For extra crispiness, broil for 2-3 minutes, watching carefully to avoid burning.
  8. Serve warm, spooning any melted butter from the pan over the top.

Notes

Use chopsticks or wooden spoons as guards to avoid slicing through the potato completely. Soften butter before mixing for easy spreading. Basting halfway through baking keeps potatoes moist and flavorful. Let potatoes rest 5 minutes after baking to allow flavors to meld. For vegan version, substitute butter with plant-based spread or coconut oil and optionally add nutritional yeast for cheesy flavor.
