Butter hasselback potatoes have thin connected slices that open as they bake, creating crisp edges around soft centers. This simple version uses russet potatoes, melted butter, salt, and pepper. Choose four similarly sized potatoes, each about eight ounces, so they finish at roughly the same time.
The cuts should stop above the base to keep each potato together. Butter goes on in two stages: the first coating seasons the outside, and the second can reach between slices after the fans begin to open. Allow enough oven time for the centers to soften fully.

Why This Recipe Works
A connected base holds the fan together, while the cut surfaces expose more potato to the oven. Butter hasselback potatoes need thin cuts of reasonably even thickness rather than a few deep wedges. About one-eighth inch between cuts gives many edges without asking you to make paper-thin slices.
The initial bake opens the slices slightly, making the second basting more effective. Butter that collects in the dish can be spooned back over the potatoes. Avoid scorching the tray juices, which can turn bitter before the potato centers are ready.
Ingredients for Butter Hasselback Potatoes
Scrub the russets and dry their skins thoroughly. Keep the skin on for support. Measure half a cup of unsalted butter for the whole batch, divide it in half, and season the potatoes with salt and pepper to taste. There is no separate garlic or herb mixture in the base formula.
For butter hasselback potatoes, choose a baking dish or rimmed metal tray that holds all four with space between them. A tightly packed dish traps more steam and slows browning. A thin slice from the bottom can stabilize a rolling potato, but remove only enough to make it sit flat.
Potatoes
- 4 medium russet potatoes (about 8 ounces each; scrubbed and dried)
- ½ cup unsalted butter (melted; divided into two ¼-cup portions)
- to taste salt and black pepper
How to Make Butter Hasselback Potatoes
Heat the oven to 425°F. Set a potato between two chopsticks or wooden spoon handles to act as cutting stops, while remembering that tapered ends sit lower and still need care. Slice down at close, even intervals without cutting through the connected base.
Brush butter hasselback potatoes with half the melted butter, including the ends and exposed surfaces, and season. Bake for thirty minutes, then brush with the reserved half, gently encouraging butter into the openings without breaking off the slices. Spoon any clean pan butter over them as needed.
Continue baking another 30–45 minutes, until a thin knife passes easily through the central flesh and the edges are browned. A large potato can take longer than the smaller ones. If the surface colors early, cover loosely while the middle finishes, then uncover briefly to dry the edges. Rest five minutes before serving.
How to Serve
Serve butter hasselback potatoes one per plate alongside roast chicken, baked fish, or a vegetable main. Their fanned shape is easiest to preserve with a broad spatula supporting the base. Spoon a little of the warm pan butter over the portions if desired.
The recipe is deliberately simple, making it useful beside more strongly seasoned food. Cheese, bacon, or herb sauces are separate optional toppings, not extra ingredients hidden in the timing or nutrition. Serve promptly while the edges are at their crispest.
Storage
Refrigerate leftover butter hasselback potatoes in covered shallow containers within two hours and use within three days at 40°F or colder. If you used foil anywhere during baking, remove it before storage. Do not leave cooked potatoes wrapped on the counter.
Reheat in an oven until the center reaches 165°F, uncovering near the end for a drier exterior. The fan edges become softer after refrigeration, and freezing is not preferred for their intended texture. Reheat the number you plan to serve rather than repeatedly warming the entire batch.
The FDA safe food handling guidance explains prompt refrigeration and temperature checks for perishable foods.
Tips and Variations
The practical check for butter hasselback potatoes is tenderness in the center, not only attractive browned edges. Test between the slices near the widest part. If one potato is substantially larger, start it earlier or allow it to stay in the oven after the others finish.
Do not force the slices apart while the potato is raw; the connected base can snap. The oven does some of that opening naturally. Use oven mitts and a long-handled brush when basting, since hot butter can collect between the cuts.
Frequently Asked Questions
How thin should the slices be?
Aim for roughly ⅛ inch, keeping the base connected so the potato stays in one piece.
Why baste butter hasselback potatoes twice?
The slices open during the first part of baking, allowing the second butter coating to reach more surfaces.
Can I use very large potatoes?
They need longer to soften. Similar eight-ounce russets make the written schedule more predictable.
Do I peel them?
Keep the skins on after scrubbing and drying, since they help support the fan.
How do I check the center?
A thin knife should pass through the widest central flesh without hard resistance, even if the edges already look crisp.

Butter-Basted Hasselback Potatoes
Ingredients
Potatoes
- 4 medium russet potatoes about 8 ounces each; scrubbed and dried
- ½ cup unsalted butter melted; divided into two ¼-cup portions
- to taste salt and black pepper
Instructions
- Heat the oven to 425°F. Scrub and dry 4 russets, about 8 ounces each. Stabilize them on a board and make slices approximately ⅛ inch apart, stopping above the base. Wooden cutting stops help, but watch the lower tapered ends.
- Set potatoes apart in a rimmed baking dish. Brush with ¼ cup melted butter, season with salt and pepper, and bake for 30 minutes.
- Brush with the remaining ¼ cup butter, carefully directing it into the opened cuts. Bake another 30–45 minutes or longer until the central flesh is completely tender and the edges are golden.
- If the outside colors before the middle softens, tent loosely with foil and continue; uncover near the end for crispness. Rest 5 minutes, then lift with a broad spatula and serve one per portion.
