Ingredients

Scale
  • 3 pounds sweet potatoes, peeled and cut into 1-inch cubes (about 4–5 medium sweet potatoes)
  • 3 tablespoons olive oil or avocado oil
  • 1 teaspoon kosher salt (Diamond Crystal preferred; if using table salt, use half)
  • 1/2 teaspoon black pepper, freshly ground
  • 1/2 teaspoon smoked paprika
  • 1/4 cup pure maple syrup (Grade A dark amber preferred)
  • 3 tablespoons unsalted butter, melted (or dairy-free butter for vegan)
  • 2 tablespoons bourbon (or substitute with 2 tablespoons apple cider + 1 teaspoon vanilla extract)
  • 1 tablespoon brown sugar, packed (light or dark)
  • 1/2 teaspoon vanilla extract
  • 1/4 teaspoon ground cinnamon
  • 1/8 teaspoon ground nutmeg (freshly grated if possible)
  • Pinch of cayenne pepper (optional)
  • 2 tablespoons fresh thyme leaves (or rosemary) for garnish (optional)
  • 1/4 cup toasted pecans or walnuts, roughly chopped for garnish (optional)
  • Flaky sea salt for finishing (optional)

Instructions

  1. Preheat your oven to 400°F (200°C). Position a rack in the middle of the oven. Line a large baking sheet with parchment paper or aluminum foil (if using foil, lightly grease it).
  2. Peel the sweet potatoes and cut them into 1-inch cubes, making them as uniform as possible.
  3. In a large mixing bowl, toss the sweet potato cubes with olive oil, salt, pepper, and smoked paprika until evenly coated. Spread them in a single layer on the prepared baking sheet, ensuring they are not touching too much.
  4. Roast for 20 minutes, then remove the pan from the oven and flip the sweet potatoes using a spatula. Return to the oven and roast for another 10-15 minutes, until fork-tender but not mushy.
  5. While the sweet potatoes are roasting, make the glaze: In a small saucepan over low heat (or microwave-safe bowl in 20-second increments), melt the butter. Whisk in maple syrup, bourbon, brown sugar, vanilla extract, cinnamon, nutmeg, and cayenne (if using). Stir until smooth. If using stovetop, let it simmer gently for 1-2 minutes to thicken slightly. Remove from heat and set aside.
  6. Once the sweet potatoes are tender, remove them from the oven. Increase the oven temperature to 425°F (220°C). Pour the glaze over the sweet potatoes and gently toss to coat every piece. Spread them back into a single layer.
  7. Return the pan to the oven and roast for another 10-15 minutes, flipping halfway through. Watch closely to prevent burning. The sweet potatoes should look glossy and sticky with dark, caramelized edges.
  8. Remove from the oven. If using fresh thyme, sprinkle it over the hot sweet potatoes immediately. Add toasted pecans or walnuts if desired, and finish with a generous pinch of flaky sea salt. Serve hot or warm.

Notes

Don’t skip the first roast—it ensures even cooking. Space the sweet potatoes out on the pan to avoid steaming. Watch the sugar during the final caramelization; it can burn quickly. Use room temperature ingredients for the glaze. Double the recipe for a crowd; leftovers reheat well in the oven or air fryer. For a non-alcoholic version, substitute bourbon with apple cider and vanilla extract.
