These little hasselback potatoes crisp at the edges, stay tender in the middle, and come together faster than roasting in the oven. Using an air fryer gives you reliably golden results with less oil and a short hands-on time. I love serving them as a simple weeknight side or a casual party snack — they look fancier than the effort they require.

The technique is straightforward: thin, evenly spaced cuts across each potato create more surface area, so every bite has a crisp edge. The air fryer’s circulating heat hits those exposed ridges and renders them perfectly. No special skills, just steady knife work and a hot basket.

I’ll walk you through the exact ingredient list and the step-by-step directions I use every time. You’ll also find practical tips on equipment, common mistakes to avoid, and a few flavor variations if you want to change things up.

The Ingredient Lineup

1 pound baby potatoes, about 1.5 inches long — small, uniform potatoes give even cooking and fit nicely in the air fryer basket.
Olive oil spray — a light, even coating crisps the ridges without adding excess oil.
2 teaspoons kosher salt — seasons the potatoes properly; kosher salt gives a clean, flaky finish.

From Start to Finish: Air Fryer Hasselback Potatoes

Preheat the air fryer to 400°F.
Rinse the baby potatoes and pat them dry.
Place one potato on a cutting board. Make 10 thin, evenly spaced crosswise cuts across the potato (no larger than 1/4 inch apart), cutting no more than 3/4 of the way through so the bottom stays intact. Repeat with the remaining potatoes.
Arrange the potatoes in a single layer in the air fryer basket with the cuts facing up, making sure not to overcrowd the basket (work in batches if necessary).
Spray the potatoes evenly with olive oil spray.
Sprinkle the potatoes evenly with the 2 teaspoons kosher salt.
Air fry at 400°F for 10–12 minutes, or until the potatoes are crisp and golden brown (check at 10 minutes and add time if needed).
Let the potatoes cool slightly, then serve warm — or store in an airtight container in the refrigerator for up to two days.

Why This Recipe Works

The hasselback cut is the key. By slicing thin gaps across the potato but leaving the base intact, you expose more surface area to hot air and oil. That creates multiple crisp edges while the interior steams just enough to stay fluffy. The air fryer speeds up that process: concentrated, circulating heat hits the ridges from all sides and shortens the cooking window compared to an oven.

Keeping the cuts shallow — no more than about 3/4 of the way through — prevents the potatoes from falling apart, so they hold their shape when you move them. The olive oil spray applies a very even coating without drowning the potatoes, and a precise amount of kosher salt finishes them cleanly. The total cook time is short, so these hit the table while still hot and crisp.

Flavor-Forward Alternatives

Want to mix up the flavor? Start from the prepared hasselback potatoes and finish with one of these simple options. Each suggestion uses no extra mandatory ingredients from the recipe, so consider them add-ons if you have them on hand.

Garlic and herb finish — after air frying, brush lightly with a mix of olive oil and minced garlic, then sprinkle chopped parsley or chives.
Parmesan crunch — in the last 1–2 minutes of air frying, sprinkle grated Parmesan over the tops so it melts and crisps.
Smoky paprika — dust the potatoes with smoked paprika before or after cooking for a warm, smoky note.
Lemony brightness — finish with a light squeeze of lemon and a few lemon zest shavings for a fresher profile.

Tools & Equipment Needed

You don’t need much to make these. A small set of reliable tools makes the technique easier and safer.

Air fryer — a countertop air fryer that can reach 400°F. Basket-style or drawer models both work.
Sharp chef’s knife — thin, even cuts depend on a sharp blade. A small paring knife can work too for greater control.
Cutting board — stable surface for slicing and assembling.
Olive oil spray — to coat the potatoes evenly. If you don’t have spray, a brush with a little oil works.
Tongs or spatula — to place and remove potatoes without tearing them.

Frequent Missteps to Avoid

These are the things I see most often when people try hasselback potatoes for the first time. Avoiding them keeps your results consistent.

Cutting too deep — if you slice all the way through, the potato will fall apart during cooking. Stop around 3/4 of the way down.
Uneven slices — wildly uneven gaps lead to some parts overcooked and some undercooked. Aim for about 1/4-inch spacing and steady hands.
Overcrowding the basket — the air fryer needs space for air to circulate. Work in batches so each potato gets exposed heat on all sides.
Skipping the dry — if the potatoes are wet, oil won’t cling and the exterior won’t crisp properly. Pat them fully dry after rinsing.
Not checking at 10 minutes — air fryers vary. Start checking at 10 minutes to avoid burning; add small increments if more time is needed.

How to Make It Lighter

This recipe is already relatively light thanks to the minimal oil. If you want to pare it down further, here are straightforward options that reduce fat or calories without losing texture.

Use less oil — swap the spray for a very light mist or skip it entirely; the air fryer will still crisp the ridges, though less aggressively.
Choose smaller potatoes — smaller baby potatoes cook faster and yield crispier surfaces for the same amount of oil.
Season wisely — rely on kosher salt and fresh herbs instead of butter-based finishes to keep calories lower.

Behind the Recipe

I first learned the hasselback cut as a time-saver for roasting: more surface area meant faster caramelization. Translating that to the air fryer felt natural. It trims oven time and gives even, reliable browning. I tested multiple cycles to find a sweet spot — 400°F, 10–12 minutes — that hits crisp edges without drying the interior.

Another small but deliberate choice: kosher salt rather than table salt. The larger flakes distribute cleanly and are easier to control, producing a satisfying crunch without oversalting. Olive oil spray is mostly for convenience and even coverage; if you prefer a different neutral oil, a light brush works too.

Prep Ahead & Store

These potatoes are forgiving if you want to prep ahead or manage leftovers.

Prep ahead — you can slice the potatoes and keep them refrigerated, covered, for a few hours before air frying. Pat them dry again just before cooking.
Storing cooked potatoes — place cooled potatoes in an airtight container and refrigerate for up to two days.
Reheating — reheat in the air fryer at 350°F for a few minutes to revive the crisp edges. The microwave will make them soft, so avoid it if you want crispness.

Ask & Learn

Questions I get most often: Can I use larger potatoes? Yes — but adjust cooking time and make a few more or slightly deeper cuts so heat penetrates. Will they be soggy if I skip oil? They’ll be less crisp; a light oil mist helps browning. How to know when they’re done? Look for golden, bubbly ridges and a fork-tender interior.

If you try different finishes, keep notes: how long in your particular air fryer, which flavor add-ons you preferred, and whether you needed extra time. Those tweaks will make this a repeatable, reliable recipe in your home kitchen.

Final Thoughts

Air Fryer Hasselback Potatoes give you high-impact presentation with minimal fuss. The method scales well: cook a single batch for two people or multiple batches for a group. Keep your knife steady, don’t overcrowd the basket, and check early — those three habits deliver the crisp, golden results you’re aiming for.

They pair well with roasted proteins, a simple green salad, or as a cozy snack with a dipping sauce. Give the basic version a run-through first, then experiment with the flavor ideas listed earlier. Small changes — a dusting of paprika, a sprinkle of cheese, or a squeeze of lemon — can turn the same base into multiple dishes over the week.
