📝 About This Recipe

Unlock the deep, caramelized potential of the humble root vegetable with this masterclass in roasting. By utilizing a high-heat salt-rub technique, we achieve a skin that is shatteringly crisp while the interior transforms into a velvety, honey-like custard. This dish elevates a simple staple into a sophisticated side that balances earthy sweetness with a decadent, herb-infused finish.

🥗 Ingredients

The Potatoes

  • 4 large Beauregard or Jewel Sweet Potatoes (uniform in size, scrubbed and dried thoroughly)
  • 2 tablespoons Extra Virgin Olive Oil (high quality)
  • 1 tablespoon Flaky Sea Salt (Maldon or similar)
  • 1/2 teaspoon Black Pepper (freshly cracked)

Whipped Herb Butter

  • 1/2 cup Unsalted Butter (softened to room temperature)
  • 1 teaspoon Fresh Rosemary (minced very fine)
  • 1 teaspoon Fresh Thyme (leaves stripped and chopped)
  • 1 teaspoon Honey (wildflower or clover)
  • 1/4 teaspoon Garlic Powder

Garnish and Texture

  • 1/4 cup Toasted Pecans (roughly chopped)
  • 2 pieces Green Onions (thinly sliced on a bias)
  • 1 pinch Red Pepper Flakes (optional for heat)
  • 4 tablespoons Greek Yogurt or Sour Cream (for a tangy finish)

👨‍🍳 Instructions

  1. 1

    Preheat your oven to 425°F (220°C). Position a rack in the center of the oven for even heat distribution.

  2. 2

    Scrub the sweet potatoes vigorously under cold water to remove any grit. Pat them completely dry with a kitchen towel; moisture is the enemy of a crispy skin.

  3. 3

    Using a sharp fork, prick each sweet potato 6-8 times all over. This allows steam to escape and prevents the potatoes from bursting.

  4. 4

    Place the potatoes on a parchment-lined baking sheet. Drizzle with olive oil and massage it into the skin until every inch is lightly coated.

  5. 5

    Generously sprinkle the flaky sea salt and cracked pepper over the oiled skins. Roll the potatoes to ensure the salt adheres to the entire surface.

  6. 6

    Slide the baking sheet into the oven. Bake for 45 to 60 minutes. You’ll know they are done when a knife slides into the thickest part with zero resistance.

  7. 7

    While the potatoes roast, prepare the herb butter. In a small bowl, combine the softened butter, rosemary, thyme, honey, and garlic powder.

  8. 8

    Use a whisk or fork to whip the butter mixture until it is light and airy. Set aside at room temperature.

  9. 9

    Once the potatoes are tender, remove them from the oven. Let them rest for 5 minutes; this allows the internal steam to redistribute, making the flesh even fluffier.

  10. 10

    Using a knife, slice a long slit down the center of each potato. Gently squeeze the ends toward the center to 'pop' the potato open, revealing the bright orange interior.

  11. 11

    Use a fork to lightly fluff the inner flesh, being careful not to puncture the bottom skin.

  12. 12

    Place a generous dollop of the whipped herb butter inside each potato, allowing it to melt into the crevices.

  13. 13

    Top with a spoonful of Greek yogurt, a sprinkle of toasted pecans, and the sliced green onions.

  14. 14

    Serve immediately while the contrast between the hot potato and cool toppings is at its peak.

💡 Chef's Tips

Always choose potatoes that are similar in thickness to ensure they finish cooking at the same time. Avoid wrapping potatoes in aluminum foil; this steams the skin and makes it soggy rather than crisp. For an extra layer of flavor, try smoking the salt or using a smoked paprika rub before roasting. If your potatoes are leaking sugar (syrup) onto the pan, don't worry—that's the natural sugars caramelizing, which adds great flavor. To test for doneness without a knife, give the potato a gentle squeeze (with an oven mitt!); it should feel soft and yielding.

🍽️ Serving Suggestions

Pair with a grilled ribeye steak or roasted chicken for a classic, hearty meal. Serve alongside a crisp arugula salad with a lemon vinaigrette to cut through the richness. Complements a glass of oaked Chardonnay or a spicy ginger beer perfectly. Works beautifully as a vegetarian main course when topped with black beans and avocado. Great as a holiday side dish alongside roasted turkey and cranberry sauce.
