Air Fryer Hasselback Sweet Potatoes with Maple Butter

Air Fryer Hasselback Sweet Potatoes are the side dish that looks like it took an hour and takes about thirty minutes. The fan cut opens the potato into dozens of thin slices, the circulating air crisps every one of those edges, and the center stays soft and custardy. Then you spoon whipped maple butter down into the cuts and let it melt through.

This is the recipe I make when I want the table to go quiet for a second. It works for a Tuesday, and it holds its own next to a holiday turkey.

If you have been making Air Fryer Baked Sweet Potatoes and want something with more presence, this is the upgrade.

Why You Will Love These Hasselback Sweet Potatoes

Thirty minutes, start to finish. Ten minutes of prep, twenty in the basket.

The cut does the work. Slicing the potato accordion-style multiplies the surface area, which means far more crispy edge per bite than a whole roasted sweet potato.

Real caramelization. Sweet potatoes are high in natural sugar. Dry, circulating air at 350°F browns those sugars into something close to candy at the tips.

Whipped maple butter finishes it. Two ingredients, whipped for a minute, and it melts down into every slice instead of sitting on top.

No oven required. Nothing heats up, and you are not competing for oven space on a holiday.

Ingredients You Need

For the sweet potatoes:

• Sweet potatoes: Four medium potatoes, roughly the same size and shape. Long and slim beats short and fat, because the slices cook more evenly. Scrub the skins well since they stay on.
• Olive oil: Two to three tablespoons. This is what crisps the skin and the cut edges. Avocado oil or grapeseed oil work the same way, and melted butter works if you would rather.
• Sea salt: One to two teaspoons. Get some down into the slices, not just on top.
• Black pepper: To taste.
• Fresh thyme or rosemary (optional): Tucked into a few of the cuts before air frying, herbs perfume the whole potato.

For the whipped maple butter:

• Butter: Half a cup, softened to room temperature. Not melted. Softened butter is what whips.
• Pure maple syrup: Three tablespoons. Real maple, not pancake syrup, which is mostly corn syrup and will taste flat here.
• Pinch of salt: It sharpens the maple.
• Cinnamon (optional): A quarter teaspoon if you want it warmer.

How to Cut Hasselback Sweet Potatoes

This is the only part that intimidates people, and there is a trick that removes all the risk.

Set up a stop. Lay two wooden spoon handles or a pair of chopsticks on either side of the potato, running lengthwise. They act as a physical barrier so your knife cannot go all the way through.

Slice at quarter-inch intervals. Use a sharp knife and cut straight down until the blade hits the handles. Move down the potato a quarter inch and repeat. Thinner slices crisp more aggressively, so if you want maximum crunch you can go closer to an eighth of an inch, but the potato gets more fragile.

Fan the slices gently. Once the potato is fully cut, press very lightly on the top to spread the slices apart. Do not force them or the base will split.

A hasselback slicing rack does the same job if you make these often. I use one whenever I am making a big batch.

How to Make Air Fryer Hasselback Sweet Potatoes

Step One: Prep the potatoes. Scrub the sweet potatoes under running water and dry them completely. A wet skin steams instead of crisping. Cut each one hasselback-style using the method above.

Step Two: Oil and season. Brush the potatoes generously with olive oil, working the brush down into the cuts. Season with sea salt and black pepper, again getting some between the slices.

Step Three: Preheat the air fryer. Set it to 350°F and let it run empty for three minutes. Dropping the potatoes into a hot basket is what starts the browning immediately instead of ten minutes in.

Step Four: Air fry. Arrange the sweet potatoes in a single layer in the basket with space between them. Cook at 350°F for 20 minutes. Around the 10-minute mark, open the basket and brush them again with oil, letting some run down into the slices. This second brush is where the crisp edges come from.

Step Five: Make the whipped maple butter. While the potatoes cook, add the softened butter, maple syrup, salt, and cinnamon to a small bowl. Whip with a hand mixer or a fork for about a minute, until it is pale and fluffy.

Step Six: Check and finish. The potatoes are done when a fork slides into the thickest part with no resistance and the edges have gone dark and crisp. Let them rest three to five minutes, then spoon the maple butter over the top so it melts down through the fan.

Cooking Time by Potato Size

Potato size	Temperature	Time
Small or baby (4–5 oz)	350°F	13–15 minutes
Medium (7–9 oz)	350°F	18–20 minutes
Large (11 oz+)	350°F	25–30 minutes

Every air fryer runs a little differently. Start checking five minutes before the low end of the range.

Tips for the Crispiest Results

• Match your potatoes. Four potatoes of similar size finish at the same moment. One oversized potato in the batch means either it is underdone or the others are dried out.
• Dry skin, always. Pat them fully dry before oiling.
• Do not crowd the basket. Air has to move around each potato. Two batches beat one crowded one.
• Brush twice. Once before, once halfway. It is the single biggest difference between good and great here.
• Add the butter after, never before. Maple butter in a 350°F air fryer for twenty minutes will burn and smoke. It goes on at the end.
• Rest before serving. Five minutes lets the interior finish softening and the edges set up crisp.

Variations

• Smoky and sweet: Add half a teaspoon of smoked paprika to the oil before brushing.
• Spiced maple: Stir a pinch of cayenne or chipotle powder into the maple butter for heat against the sweetness.
• Savory herb: Skip the maple butter entirely and finish with garlic butter, fresh thyme, and flaky salt.
• Loaded: Top with sour cream, chives, and crumbled bacon, the way you would a baked potato.
• Brown sugar: Swap the maple syrup for two tablespoons of brown sugar in the whipped butter for a deeper molasses note.

Can You Make Hasselback Sweet Potatoes in the Oven?

Yes. Cut and season them exactly the same way, then roast at 425°F for 40 to 50 minutes on a parchment-lined sheet pan, brushing with oil once at the halfway point. Add the maple butter after they come out.

The air fryer version is faster and gets crispier edges because of the air circulation, but the oven handles a larger batch, which matters for a holiday table.

You can also make these in a Ninja Foodi on the air crisp setting using the same time and temperature.

Storing and Reheating

Refrigerator: Cool completely, then store in an airtight container for three to four days. Keep the maple butter separate so the potatoes do not go soggy.

Freezer: Wrap individually in foil, then bag. They hold for two to three months. Freeze them plain, without the butter.

Reheating: Back into the air fryer at 350°F for five to seven minutes brings the crisp edges right back. The microwave will make them soft, so use it only if you are in a hurry. From frozen, air fry at 350°F for 10 to 12 minutes.

What to Serve With Air Fryer Hasselback Sweet Potatoes

These sit comfortably next to almost any roasted protein. They are especially good with a Ninja Speedi Turkey Breast for a smaller holiday meal, or with a simple spinach and strawberry salad when you want something bright against all that sweetness.

For a vegetarian plate, serve one over a bed of quinoa with the maple butter and toasted nuts.

Frequently Asked Questions

Do I need to peel the sweet potatoes? No. The skin holds the slices together while they cook and adds fiber and texture. Just scrub it well.

Why did my potato split apart? The knife went too deep, or the slices were fanned too aggressively. Use the wooden spoon trick and press only lightly when spreading the cuts.

Can I use regular potatoes instead? Yes. Russets work beautifully with this method, though they need closer to 25 to 30 minutes at 350°F and they do not caramelize the same way since they have less sugar. My Air Fryer Garlic Butter Hasselback Potatoes are built for russets specifically.

Can I prep these ahead? Slice and season them up to 24 hours in advance, cover, and refrigerate. The whipped maple butter also keeps for a week in the fridge. Let it come back to room temperature before serving.

Why are my edges not crisping? Usually one of three things: the basket was crowded, the skin was still damp when you oiled it, or you skipped the halfway brush. Adding three to five minutes at 375°F at the very end will also push them further.

Should I preheat the air fryer? Yes. Three minutes at 350°F. It shortens the total cook time and starts the browning right away.

Can I use frozen sweet potatoes? Not for this recipe, since you cannot hasselback a frozen potato. For a frozen option, try Frozen Sweet Potato Fries in the Instant Pot Air Fryer.
