This version of Hasselback potatoes has been my go-to when I want something that feels special without a lot of fuss. I first tried this technique on a chilly weeknight when guests were arriving and I wanted a side that looked like effort, but actually comes together quickly. The thin, accordion-like slices let melted butter and seasonings reach more of the potato surface so every bite has a perfect contrast of crisp ridges and a fluffy interior. The smell of butter and roasted russets pulling apart in the oven is one of those small kitchen pleasures that always gets compliments.

What makes these stand out for me is the balance between technique and comfort: a simple trick with chopsticks to keep the bottom intact, a brush of melted unsalted butter, and the right bake time at 425°F. I remember the first time I served these at a family dinner—my aunt asked for the “method” three times so she could write it down. They’re versatile, delicious, and they pair beautifully with everything from roast chicken to a crisp green salad. When dinner needs a little lift, these are the potatoes I reach for.

Ingredients

• Russet potatoes (4 large): Choose firm, dry potatoes with few blemishes. Russets have the starchy texture that crisps beautifully on the edges and yields a fluffy interior. If you can, pick uniform sizes for even cooking.
• Unsalted butter (4 tablespoons), melted, divided: Butter adds flavor and helps the edges brown. Using unsalted lets you control seasoning; I like Plugra or Land O Lakes for consistent results.
• Kosher salt (1 teaspoon): Coarser kosher salt seasons more gently and adheres to the potato surface; Diamond Crystal or Morton's are both fine—adjust to taste if you use table salt.
• Black pepper (1/2 teaspoon): Freshly ground black pepper gives a subtle heat—add more to taste when serving.
• Extra salt and pepper to taste: A final seasoning at the table helps each person customize their portion; flaky finishing salt like Maldon is lovely if you have it.

Instructions

Prepare the oven and baking sheet: Arrange the oven rack in the middle position and preheat to 425°F. Use an unlined baking sheet so the bottoms brown well; if you prefer easier cleanup, you can line the sheet with foil but the crisping will be slightly reduced. Slice the potatoes hasselback-style: Place one potato between two chopsticks or skewers to act as a guard. With a sharp chef’s knife, make vertical slits about 1/8 inch apart, cutting straight down until the blade gently hits the chopstick so the bottom remains intact. This creates the fan effect while keeping each potato whole. Repeat for all potatoes. A slightly dull knife will crush the edges; keep the blade sharp for clean slices. Brush with butter and season: Arrange the potatoes on the baking sheet and use a basting brush to coat about half of the melted butter over each potato, working some into the slits. Sprinkle with the measured kosher salt and 1/2 teaspoon freshly ground black pepper. The first coat begins the browning process and flavors the inside of the slices. Bake and separate slices: Bake at 425°F for 30 minutes. After 30 minutes, remove the tray and use a knife or tines of a fork to gently pry the layers slightly apart—this exposes more surface area. Brush on the remaining melted butter, which helps those exposed edges crisp and caramelize evenly. Finish baking and serve: Return to the oven for 30–35 more minutes, or until the edges are deeply golden and crisp and a skewer slides easily into the center. Total bake time depends on potato size; larger potatoes may need a few extra minutes. Serve warm, offering additional salt and pepper at the table.

Storage Tips

To store leftovers, let the potatoes cool completely, then tightly wrap them in plastic wrap or place in an airtight container. Refrigerate for up to 3 days. For longer storage, freeze fully baked and cooled potatoes in a single layer on a tray until firm, then transfer to a freezer bag for up to 3 months. Reheat in a 375°F oven for 12–18 minutes to restore crispness; microwaving will warm the interior but soften the crisp ridges. Look for loss of crispness or off odors as signs of spoilage.

Ingredient Substitutions

If you don’t have russets, Yukon Golds will work but the texture will be creamier and the edges may brown faster; reduce the final bake time slightly. Swap butter for olive oil for a dairy-free option—use about the same volume (4 tablespoons) but expect a different flavor and slightly less golden crisping. For a lower-fat version, use 2 tablespoons of butter or oil and mist the rest with a high-heat oil spray. Add minced garlic or herb butter during the final brush for more aromatics—about 1 clove garlic per potato mixed into the melted butter is a tasty ratio.

Serving Suggestions

Serve these alongside roast chicken, grilled steak, or a fresh green salad. For a party, top with grated Parmesan and chopped parsley right after baking, or add a dollop of sour cream and chives for a loaded-style finish. They pair beautifully with pan-seared salmon or a hearty pot roast. For a brunch twist, crisp them, then top each with a poached egg and a sprinkle of smoked paprika.

Cultural Background

The technique comes from Sweden, where thinly sliced potatoes baked with butter or oil became known as Hasselback after a Stockholm restaurant called Hasselbacken in the 1940s. Over the decades the method spread internationally and evolved—some versions include cream or breadcrumbs between slices, while others focus on crisping and simple seasonings. The fundamental idea is to increase surface area for browning while keeping the potato intact, a concept treasured in many roasting traditions.

Seasonal Adaptations

In winter, enrich the butter with chopped rosemary or thyme and a pinch of smoked sea salt for a cozy flavor. Spring and summer call for lighter finishes: a squeeze of lemon and chopped parsley or a sprinkle of fresh dill brighten the dish. For autumnal dinners, fold in a little grated aged cheddar during the final 10 minutes of baking to create a gooey, savory topping that pairs well with roasted root vegetables.

Meal Prep Tips

For meal prep, partially bake the potatoes (first 30 minutes), cool them, and refrigerate for up to 24 hours. When ready to serve, pull the layers apart, brush with butter, and finish at 425°F for 20–30 minutes until crisp. This shortens active evening time significantly and keeps texture excellent. Use shallow, wide containers to avoid crowding which can steam the edges instead of crisping them.

These Hasselback potatoes are one of those satisfying dishes that feel both nostalgic and refined. Try them with different toppings and make them your own—once you master the slicing technique, you’ll find endless ways to enjoy their crispy, buttery charm.
