Ingredients You’ll Need
These ingredients are deceptively simple, but each one plays an essential role in building the irresistible texture and flavor of this dish. From the creamy butter to the fresh herbs and the perfectly starchy potatoes, they come together beautifully to create an unforgettable experience.
- Salted butter: Provides richness and melts into the slices for ultimate moistness and flavor.
- Extra-virgin olive oil: Adds a lovely fruitiness and helps crisp up the edges flawlessly.
- Shallot: A subtle sweetness that enhances the garlic and herb notes without overpowering.
- Garlic cloves: Thinly sliced to infuse the butter with aromatic depth and a mild kick.
- Fresh rosemary: Adds an earthy, piney fragrance both cooked and sprinkled fresh at the end.
- Medium baking potatoes (russets): Perfectly starchy and sturdy for slicing thinly and crisping up beautifully.
- Sea salt: Elevates flavors and aids in the perfect seasoning of each slice.
- Freshly grated Parmesan cheese: Creates a golden, crispy crust with its nutty, salty character.
How to Make Hasselback Potatoes with Garlicky Herb Butter and Parmesan Recipe
Step 1: Prepare Your Oven and Ingredients
Begin by preheating your oven to 425°F, placing the rack in the center. This temperature ensures a beautifully crisp exterior without drying out the tender potato layers inside. Meanwhile, get all your ingredients ready; chopping the shallot and garlic, and prepping the fresh rosemary will make the cooking process smooth and enjoyable.
Step 2: Infuse the Herb Butter
In a small saucepan over medium-low heat, melt the butter with olive oil, shallots, sliced garlic, and rosemary sprigs. As it warms, the garlic and herbs infuse their incredible flavors into the melted butter, creating a luscious garlicky herb mixture that will soak into each potato slice, making every bite irresistible.
Step 3: Prepare the Potatoes
First, peel each large baking potato to ensure a smooth surface. Placing them in cold water helps prevent browning while you work. Then, carefully slice very thin crosswise layers all along each potato, using two chopsticks or wooden skewers on either side as a stopping guide. This technique lets you slice almost all the way through without cutting completely, creating those signature fanned layers that soak up the butter and crisp perfectly.
Step 4: Start Roasting with Herb Butter
Strain the infused butter mixture to remove the solids, then place the sliced potatoes in your baking dish or a cast-iron pan. Drizzle half the herb butter generously over them, making sure it seeps between the slices. Sprinkle with sea salt for that perfect seasoning. Pop the dish into your preheated oven and roast for about 45 to 50 minutes, until the potatoes are tender and the edges start to turn golden brown.
Step 5: Broil to Perfection and Add Parmesan
After roasting, take the potatoes out to drizzle with the remaining herby butter. Switch your oven to broil, then return the potatoes for 5 to 10 minutes — this step crisps up the edges beautifully. Finally, sprinkle the freshly grated Parmesan cheese all over the potatoes and broil again for 3 to 5 minutes until the cheese turns a gorgeous golden brown and forms a crunchy, savory topping that’s simply irresistible.
How to Serve Hasselback Potatoes with Garlicky Herb Butter and Parmesan Recipe
Garnishes
Freshly minced rosemary sprinkled over the browned Parmesan adds a burst of color and herbal brightness that really elevates this dish. Feel free to add a tiny pinch of flaky sea salt or even a sprinkling of finely chopped chives for a subtle oniony pop to add even more flavor layers to your presentation.
Side Dishes
Hasselback Potatoes with Garlicky Herb Butter and Parmesan Recipe shine alongside roasted meats like a juicy steak or herb-roasted chicken, but they also love pairing with vibrant steamed vegetables or a crisp green salad to balance the richness. These potatoes bring a comforting and elegant touch to almost any meal!
Creative Ways to Present
Serve them straight from a rustic cast-iron skillet at the table for a heartwarming presentation, or place each potato on a small individual plate drizzled with a little extra garlic butter. You can even cut them into slices to serve as bite-sized appetizers at your next gathering—the perfect savory treat that always disappears fast.
Make Ahead and Storage
Storing Leftovers
If you have any leftovers, gently cool the Hasselback Potatoes with Garlicky Herb Butter and Parmesan Recipe to room temperature. Store them in an airtight container in the refrigerator for up to 3 days. The crispy edges might soften slightly but the flavors remain just as delightful.
Freezing
While you can freeze these potatoes, it’s best to freeze before the final Parmesan broiling step. Wrap the roasted, butter-coated potatoes tightly in plastic wrap and then foil to prevent freezer burn. You can keep them frozen for up to 1 month. To finish, thaw fully and broil with fresh Parmesan to regain that signature crispness.
Reheating
To reheat and keep as much crispiness as possible, warm the potatoes in a preheated oven at 350°F for 15 to 20 minutes. Avoid microwaving if you want to preserve the texture, as it can make the potatoes soggy. Once warmed, a quick broil for a couple of minutes can revive the golden edges perfectly.
FAQs
Can I use other types of potatoes for this recipe?
While russet potatoes are ideal for their starchy texture, you can try Yukon Golds for a slightly creamier bite. Just keep in mind that waxier potatoes may not crisp up as nicely on the edges.
How thin should the slices be when cutting the potatoes?
The goal is to slice thinly enough (about 1/8 inch) to allow the butter and seasonings to seep inside but not so thin that the potato falls apart. Using chopsticks or skewers as a guide helps you slice evenly and safely.
Is it necessary to peel the potatoes?
Peeling is recommended for smooth, even slices and to ensure the garlic herb butter penetrates fully. However, if you love a rustic look, leaving the skins on works too—just scrub them well before slicing.
Can I make the garlicky herb butter ahead of time?
Absolutely! The butter mixture keeps well for up to 2 days in the fridge. Warm it gently before drizzling over the potatoes for the best results.
What can I substitute for Parmesan if needed?
Pecorino Romano or Asiago cheese are great alternatives for a similar salty, nutty flavor. For a dairy-free option, a sprinkle of nutritional yeast can add a cheesy impression, though it won’t melt as nicely.
Final Thoughts
My absolute favorite thing about this Hasselback Potatoes with Garlicky Herb Butter and Parmesan Recipe is how effortlessly impressive it feels, yet how simple it is to make.

- Yield: 6 servings
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
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
