Description

Our easy Hasselback potato recipe yields crispy, beautifully sliced potatoes drizzled with a garlicky herb butter and topped with melted Parmesan cheese. This show-stopping side dish offers a perfect balance of crispy edges and tender insides, enhanced by fragrant rosemary and shallots for a flavorful, irresistible roast potato experience.


Ingredients

Herb Butter

  • ½ cup (1 stick) salted butter
  • ¼ cup extra-virgin olive oil
  • 1 small shallot, chopped
  • 4 large garlic cloves, sliced
  • 2 sprigs rosemary (plus 2 teaspoons minced rosemary for garnish)

Potatoes

  • 6 medium baking potatoes, such as russets (6-8 ounces each), peeled
  • ½ teaspoon sea salt
  • ½ cup freshly grated Parmesan cheese


Instructions

  1. Preheat and Prepare Butter Mixture: Preheat your oven to 425°F (220°C) and position a rack in the center. In a small saucepan over medium-low heat, combine the butter, extra-virgin olive oil, chopped shallot, sliced garlic, and rosemary sprigs. Heat gently until the butter melts and the ingredients meld for about 2 minutes.
  2. Prepare Potatoes: Peel the potatoes and place them in a bowl of cold water to prevent browning. Then, slice a thin layer off one side of each potato to create a flat base. Using two chopsticks or wooden skewers along the long sides of each potato as a guard, make thin crosswise slices across the potato without cutting all the way through.
  3. Strain Herb Butter and Assemble: Using a fine mesh strainer, strain the warm herb butter mixture into a small bowl to remove solids. Arrange the sliced potatoes in a 12-inch cast-iron skillet or a 9×13-inch baking dish. Drizzle half of the strained herb butter over the potatoes and sprinkle evenly with sea salt.
  4. Roast Potatoes: Roast the potatoes in the preheated oven for 45-50 minutes, or until they are fork-tender and starting to brown on the edges.
  5. Broil for Crispy Finish: Remove the potatoes from the oven and drizzle with the remaining herb butter. Turn on the broiler. Return the potatoes to the oven and broil for 5-10 minutes until the edges are crispy and golden.
  6. Add Parmesan and Final Broil: Remove the potatoes, sprinkle the freshly grated Parmesan cheese evenly over the tops, and broil again for 3-5 minutes until the cheese is melted and browned.
  7. Garnish and Serve: Transfer the Hasselback potatoes to a serving platter or individual plates. Sprinkle with the minced rosemary and serve immediately for the best flavor and texture.

Notes

  • Be careful to slice the potatoes thinly but without cutting all the way through to maintain the classic Hasselback shape.
  • Using chopsticks or wooden skewers along the sides helps prevent slicing through the bottom of the potatoes.
  • If you prefer, you can use kosher salt instead of sea salt.
  • The Parmesan cheese adds a nutty, savory topping—feel free to substitute with Pecorino Romano or another hard cheese if desired.
  • Serve immediately after broiling to keep the edges crispy.
  • This dish pairs beautifully with roasted meats or grilled vegetables.
