How to Make Hasselback Potatoes with Garlic, Rosemary, and Parmesan Recipe

Step 1: Preheat and Prepare

Start by preheating your oven to 425°F, positioning the rack in the center. This ensures even heat distribution, so your potatoes roast perfectly golden and tender.

Step 2: Flavor the Butter

In a small saucepan over medium-low heat, melt together the salted butter and extra-virgin olive oil. Add chopped shallot, sliced garlic, and whole rosemary sprigs. Let this simmer gently for about 2 minutes. This infused butter will soak deep into the potatoes, bringing layers of flavor that make every bite a delight.

Step 3: Prepare the Potatoes

Peel your baking potatoes and drop them into a bowl of cold water to prevent them from browning. Then, carefully slice a thin layer off one side of each potato so they rest flat. Lay each potato flat-side down between two chopsticks or wooden skewers. Using a sharp knife, make thin crosswise cuts along the potato, stopping when you hit the chopsticks—this clever trick keeps your slices intact while allowing the seasoning to penetrate.

Step 4: Roast to Perfection

Strain the infused butter to remove shallots, garlic, and rosemary sprigs, then drizzle half over the sliced potatoes placed in a baking dish or cast-iron pan. Sprinkle sea salt evenly over the potatoes. Roast them in the oven for 45 to 50 minutes until tender and starting to brown at the edges—an enticing aroma will fill your kitchen by now!

Step 5: Crispen and Cheese It Up

Pull the potatoes from the oven and drizzle with the remaining butter mixture. Turn on your broiler and return the potatoes to the oven for 5 to 10 minutes until the edges crisp delightfully. Next, sprinkle freshly grated parmesan over the top and broil for another 3 to 5 minutes until the cheese forms a bubbly, golden crust that is utterly irresistible.

Step 6: Serve Warm and Garnish

Transfer your masterpiece to a serving platter and garnish generously with minced rosemary for that burst of herbal freshness. These potatoes are best served hot straight from the oven to enjoy the contrast of crispy, cheesy edges and soft, buttery interiors.

Six hasselback potatoes with thin, even slices fanned out, are arranged inside a shiny silver frying pan. Each potato is golden brown at the edges where the slices separate, and topped with a layer of finely grated white cheese. The pan holds a shallow pool of melted butter or oil with a warm yellow color. The pan is set on a white marbled surface, and the metal handles of the pan stretch out to the left and right sides of the image. Photo taken with an iphone --ar 4:5 --v 7

Garnishes

Sprinkling minced fresh rosemary right before serving adds a lively, fragrant touch that complements the rich garlic butter and cheesy notes. A light dusting of flaky sea salt or a few shavings of extra parmesan cheese can elevate flavors even more, making each bite an experience.

Side Dishes

These Hasselback Potatoes pair beautifully with roasted meats like chicken, steak, or pork. They also shine alongside a fresh green salad or sautéed vegetables for a well-rounded meal. The crispy texture and herbal aroma create a nice contrast to tender proteins and lighter sides.

Creative Ways to Present

For a fun twist, try topping each potato with a dollop of crème fraîche or sour cream and a sprinkle of chives—turning this side into a mini loaded potato. Alternatively, arrange the potatoes on a rustic wooden board with small ramekins of aioli, pesto, or spicy ketchup for dipping, making it perfect for casual gatherings or dinner parties.

Make Ahead and Storage

Storing Leftovers

Once cooled, store leftover Hasselback Potatoes with Garlic, Rosemary, and Parmesan Recipe in an airtight container in the refrigerator. They will keep well for up to 3 days, maintaining their flavor and texture for delicious quick meals later on.

Freezing

Although it’s best enjoyed fresh, you can freeze leftover roasted potatoes by spreading them on a baking sheet to freeze individually, then transferring to a freezer-safe bag. Freeze for up to 2 months, but know the crispiness might soften after thawing.

Reheating

To bring back that fantastic crispy edge, reheat potatoes in a preheated oven at 375°F for 10 to 15 minutes, uncovered. Avoid the microwave if possible since it makes the potatoes soggy. This way, they’ll taste almost as good as freshly made.

FAQs

Can I use other types of potatoes?

Russet potatoes are ideal because their starchy interior crisps nicely outside while staying fluffy inside. Yukon Golds can work too, offering a creamier texture, but waxy potatoes may not crisp as well.

Do I have to peel the potatoes?

Peeling is traditional for Hasselback potatoes as it allows the butter and parmesan to crisp directly on the surface. However, you can leave the skins on if you prefer an earthier flavor and additional texture—just wash them thoroughly first.

How thin should the slices be?

Your slices should be about ⅛ inch thick. The key is slicing thin enough so the potatoes fan out during roasting, but not so thin they break apart. Using chopsticks or skewers on each side is a helpful trick to prevent cutting all the way through.

Can I make this recipe vegan?

Yes! Simply replace the butter with a plant-based alternative and swap parmesan for a vegan cheese or nutritional yeast. The olive oil and garlic rosemary flavors still shine through.

Why is my parmesan not browning?

Make sure your broiler is fully heated and place the potatoes close to the heat source. Broil for just a few minutes and watch carefully—parmesan melts and browns quickly but can burn if left too long.

Ingredients

Butter Mixture

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 for garnish)

Potatoes

6 medium baking potatoes, such as russets (6–8 ounces each)
½ teaspoon sea salt
½ cup freshly grated parmesan cheese

Instructions

Preheat the oven: Set your oven to 425°F (218°C) and position the rack in the center to prepare for roasting the potatoes evenly.
Prepare the garlic butter: In a small saucepan over medium-low heat, melt the butter and add olive oil, chopped shallot, sliced garlic, and rosemary sprigs. Cook gently until the butter is melted and aromatic, about 2 minutes.
Prepare the potatoes: Peel the potatoes carefully and place them in a bowl of cold water to prevent browning while you proceed to slice them.
Slice the potatoes: Trim a thin layer off one side of each potato so it can rest flat. Place the potato flat side down, then hold chopsticks or wooden skewers along the sides to limit the knife depth. Slowly slice thin crosswise slits without cutting all the way through, creating a fan effect.
Roast the potatoes: Strain the garlic butter mixture through a fine mesh strainer into a small bowl. Place the sliced potatoes into a 12-inch cast-iron pan or a 9×13-inch baking dish. Drizzle half of the butter mixture over the potatoes and sprinkle with sea salt. Roast in the oven for 45-50 minutes until fork tender and beginning to brown.
Broil to crisp ends: Remove the potatoes from the oven and drizzle with the remaining butter mixture. Turn on the broiler. Return the potatoes to the oven and broil for 5-10 minutes until the edges become crispy and golden brown.
Add parmesan cheese: Sprinkle the potatoes evenly with the freshly grated parmesan cheese. Broil again for 3-5 minutes until the cheese is bubbly and browned on top.
Serve: Transfer the Hasselback potatoes to a serving platter or individual plates. Garnish with minced rosemary and serve immediately for the best flavor and texture.

Notes

Using chopsticks or skewers while slicing helps prevent cutting the potatoes all the way through, ensuring the slices stay attached for the classic Hasselback appearance.
Be careful when broiling so the cheese and edges do not burn; watch closely during the final minutes.
This dish pairs beautifully with roasted meats, poultry, or as a hearty vegetarian main course.
Leftovers can be reheated in the oven to maintain crispiness.
You can customize the topping by adding herbs like thyme or swapping parmesan with cheddar for variation.
