Hasselback Sweet Potato Gratin Recipe

Recipe by: Ronne Day (WebstaurantStore Food Stylist)

Serves: 6 - 8

Total Time: 120 minutes

Ingredients

Mustard Seed
  • 1 oz. (2 Tbsp.) unsalted butter, at room temperature
  • 1 cup heavy cream
  • 2 Tbsp. finely chopped garlic
  • 1 Tbsp. toasted mustard seed
  • 1 Tbsp. horseradish
  • 1 1/2 tsp. kosher salt
  • 1/2 tsp. freshly ground black pepper
  • 3 1/2 lb. sweet potatoes, peeled
  • Fresh lemon juice
  • 1/2 cup finely grated Manchego cheese (about 1 oz.)
  • 2 Tbsp. thinly sliced scallions

Directions

Salt
  1. Heat your oven to 375°F and position a rack in the center.
  2. Coat a 3-quart baking dish with butter.
  3. In a medium bowl, combine the cream, garlic, mustard seed, horseradish, 1 1/2 tsp. salt, and 1/2 tsp. pepper.
  4. Cut the tapered ends off the potatoes and discard. Thinly slice the potatoes crosswise into 1/8" slices. Sprinkle the potatoes with a squeeze of fresh lemon juice and arrange them in the baking dish.
  5. Pour the cream mixture over the potatoes and top with the Manchego cheese.
  6. Place the baking dish on a rimmed baking sheet and transfer to the oven. Bake until golden brown and bubbling, about 1 to 1 1/2 hours.
  7. Remove from the oven and allow to rest for 10 minutes. Top with the scallions and serve.
