Jamie Oliver's Hasselback Potatoes Recipe: Herb-Butter Roast With Crispy Vinegar Edges

Jamie Oliver's Hasselback potatoes recipe transforms simple spuds into a restaurant-worthy centerpiece with crispy vinegar edges and fluffy herb-butter centers. The secret lies in precise vertical slicing—leaving the bottom intact—so each potato stays structurally sound while baking into golden perfection.

I’ve perfected this technique over years of weeknight dinners, and it never fails to impress, even with picky eaters.

This method requires just five key ingredients and 45 minutes in the oven, yet delivers results that taste like you spent hours prepping.

The herb butter—packed with garlic, rosemary, and thyme—infuses every slice, while a splash of apple cider vinegar in the final minutes creates those signature crispy, tangy edges that set this dish apart. No fancy equipment needed, just a sharp knife and a baking sheet.

By the time they emerge from the oven, your potatoes will be golden and crisp on the edges with tender, buttery interiors that practically melt in your mouth.

The aroma alone will have everyone gathering at the table, and the visual appeal—those perfectly spaced slices—makes them as beautiful as they are delicious. Serve alongside grilled chicken, steak, or even as a vegetarian main with a fresh salad.

For an extra touch, sprinkle with flaky sea salt and fresh parsley before serving. This recipe scales beautifully for crowds, making it ideal for holiday dinners or family gatherings. Let’s get cooking—your taste buds will thank you.

Ingredients for jamie oliver hasselback potatoes

Five simple ingredients transform humble potatoes into a showstopping herb-butter roast.

The potatoes are the star—Russet is ideal for their waxy texture and even cooking. Grab the smallest uniform ones you can find at Whole Foods or your local market; they slice more evenly. If they feel soft or have sprouts, skip them. The herb butter is where the magic happens: cold unsalted butter (the good stuff, not margarine) holds its shape better when cutting the slices. I always grab Plugrá or Kerrygold if I'm splurging, but store-brand works fine. Fresh herbs are non-negotiable here—dried just won’t give that same aromatic punch.

No fresh rosemary? Dried works at half the amount, but it lacks that piney brightness. Short on thyme? Fresh oregano is a decent swap, though the flavor profile shifts slightly. For the garlic, jarred minced is fine in a pinch, but fresh minced gives way better flavor. The vinegar is crucial for those crispy edges—Bragg or Heinz both work, but avoid anything with added sugar. If you're prepping ahead, par-cook the potatoes for 10 minutes before slicing to prevent them from falling apart when you cut them.

These potatoes reheat beautifully—just 5 minutes at 350°F with a splash of water in the pan. Store leftovers in the fridge for 3-4 days, but honestly, they're best fresh. For a crowd, double the recipe—just use two baking sheets. The herb butter mixture keeps in the fridge for 1 week if stored in an airtight container, so make extra. Garnish with parsley right before serving—it adds that final pop of color and freshness that makes the dish look restaurant-worthy.

Step-by-step instructions for herb-buttered hasselback potatoes

Here's how to achieve Jamie Oliver's signature crispy, golden edges with a luscious herb butter center.

Start by preheating your oven to 425°F. Place each of the 4 whole Russet Potatoes on a cutting board and use a sharp chef's knife to make ¼-inch deep horizontal slices all the way to the bottom—leave the base intact so they stay upright. I like to make these cuts about ⅛-inch apart for even cooking and that signature fan effect.

Gently separate the slices slightly with your fingers to create space for the butter to infuse. This is where the magic happens—those thin cuts allow the butter and herbs to penetrate while maintaining the potato's structure. Don't force them apart too much, or they'll collapse during roasting.

In a medium bowl, combine the 0.5 cup unsalted butter (cold, in small cubes), 0.25 cup finely chopped fresh rosemary, 2 tbsp chopped fresh thyme, 4 minced garlic cloves, and 1.5 tsp flaky sea salt. Using your hands, work the mixture until it forms a loose, crumbly paste—this ensures even distribution when we stuff the potatoes.

Here's the thing—using cold butter is crucial. It melts gradually during roasting, creating a silky sauce that coats each slice. If you use softened butter, it'll pool at the bottom instead of creating that luxurious herb-butter center we're after.

Using a small spoon or your fingers, carefully press the herb butter mixture between each slice of the potatoes, working it all the way to the base. This is where patience pays off—take your time to ensure every slice gets an even coating. Place the stuffed potatoes on a parchment-lined baking sheet, spacing them about 1 inch apart to allow air circulation.

Drizzle each potato with 1 tbsp olive oil and sprinkle lightly with any remaining herb butter mixture. Roast for 45-50 minutes, turning the potatoes halfway through, until the edges are deep golden brown and crispy. The internal temperature should reach 205°F—this ensures they're tender all the way through while maintaining that perfect crust.

About 10 minutes before the potatoes are done, increase the oven temperature to 450°F. Remove the potatoes from the oven and brush each slice generously with 2 tbsp apple cider vinegar. Return them to the oven for the final 5-7 minutes of roasting—this creates that signature crispy, vinegar-kissed edge that sets these apart from regular Hasselbacks.

The vinegar reacts with the hot potatoes to form a caramelized crust while adding a bright, tangy contrast to the rich herb butter. Watch them closely—they go from golden to deep mahogany fast at this temperature. Remove them when the edges are crisp and the vinegar has evaporated slightly.

Transfer the potatoes to a serving platter and let them rest for 5 minutes—this allows the juices to redistribute so every slice is moist and flavorful. While they rest, sprinkle generously with 0.25 cup chopped fresh parsley for a pop of color and freshness.

Serve immediately with the crispy edges facing up. Each slice should have that perfect balance: crispy, vinegar-bright edges that give way to tender, herb-infused potato slices drenched in buttery goodness. The parsley not only looks stunning but also adds a fresh herbal note that cuts through the richness.
