Air Fryer Fingerling Potatoes (Crispy in 15 Minutes)

Air fryer fingerling potatoes are the side dish I make when I have fifteen minutes and no interest in chopping anything. They go in whole — no cutting, no peeling, no parboiling — and come out with blistered, salty skins and centers that taste like they’ve been buttered before you’ve touched them with butter.

I made these for a BBQ last spring and stood there the whole night explaining what a fingerling potato was. Then everyone went home and bought some. They’ve been in my rotation of potato side dishes for BBQ ever since.

This is my base recipe: four ingredients, one bowl, one basket. Once you have it down, it’s the jumping-off point for every other version — including my garlic roasted fingerling potatoes, which take the same potatoes in a much louder direction.

Why Fingerlings Belong in the Air Fryer

A regular baked potato takes an hour in the oven. Fingerlings are about the size of your finger, so there’s far less mass to heat through — and an air fryer moves hot air fast enough to dry the skin before the inside overcooks.

That combination is what you’re actually after in a roasted potato: a skin that shatters a little and a center that stays creamy. Ovens can do it. Ovens also take three times as long and heat up your entire kitchen to do it.

The other advantage is scale. If you want four servings of potatoes, you shouldn’t have to preheat a full-size oven for twelve minutes first. It’s the reason nearly every potato on this site eventually ends up in the basket — you can see the whole collection in my air fryer potato recipes.

What Are Fingerling Potatoes?

The first time I bought fingerling potatoes I was at Trader Joe’s, and I picked them up purely because they looked strange.

They’re a waxy, thin-skinned potato harvested small and narrow — usually 2 to 4 inches long — and they hold their shape when cooked instead of going fluffy and falling apart. Common varieties include Russian Banana (yellow, slightly sweet), French Fingerling (rosy skin), and Purple Peruvian, which stays genuinely purple all the way through.

The thin skin is the part that matters here. It crisps fast, and it lets seasoning reach the flesh underneath, which is why these need so little help to taste like something.

They are not the same as baby potatoes or new potatoes, even though those work as substitutes. Baby potatoes are just regular varieties picked early. Fingerlings grow that shape on purpose.

Ingredients

Full amounts and step-by-step directions are in the printable recipe card at the bottom of this post, along with nutrition information.

• Fingerling potatoes — Look for ones that are roughly the same size so they finish at the same time. If yours are wildly uneven, see the whole vs. halved section below.
• Olive oil — Enough to coat every potato with a thin film. This is what crisps the skin; dry spots stay leathery. Avocado oil works too.
• Kosher salt — Coarse salt clings to the skin better than table salt.
• Black pepper — Freshly cracked if you have it.

That’s it. Four things. The potato is doing the work.

Whole or Halved? Here’s How to Decide

This is the fork in the road for this recipe, and it changes your result more than any seasoning will.

• Cook them whole when the potatoes are small (under about 2 inches) and you want maximum creamy interior. The skin seals everything in and the inside steams itself. This is the version in my recipe card and my default.
• Halve them lengthwise when the potatoes are big, when they’re uneven, or when you want more crispy surface area. Cut sides go face-down against the basket and develop a flat golden crust that whole potatoes never get.
• Quarter them only if they’re unusually large. Any smaller and you’ve made air fryer potato chunks, which is fine, but it isn’t this recipe. If you’re in the mood to actually get out a knife and do something with it, make hasselback potatoes instead.

One rule regardless: whatever you do, do it to all of them. A basket with whole potatoes and halves in it will give you burnt halves and raw centers.

How to Make Air Fryer Fingerling Potatoes

Step One — Season. Scrub and thoroughly dry the potatoes. Add them to a large bowl with the olive oil, kosher salt, and pepper, and toss until every potato is glossy. Take an extra fifteen seconds here; the potatoes at the bottom of the bowl always get shorted.

Step Two — Air fry. Arrange the potatoes in a single layer in the air fryer basket or on the tray. Set to 400°F on the air fry setting for 12 to 15 minutes, shaking the basket once at the halfway mark.

Step Three — Check. They’re done when a fork slides into the thickest one with no resistance and the skins have gone wrinkled and blistered. If the fork stops partway, give them 3 more minutes and check again.

Serve them hot. Potatoes are at their best about ninety seconds out of the basket.

Air Fryer Fingerling Potato Time and Temp Chart

Cooking time depends almost entirely on size and cut. Use 400°F for all of these and adjust the clock:

Cut	Temp	Time	Shake at
Whole, small (1–2″)	400°F	12–15 min	7 min
Whole, large (3″+)	400°F	16–20 min	9 min
Halved lengthwise	400°F	10–12 min	6 min
Quartered	400°F	8–10 min	5 min

Basket-style air fryers run hotter than oven-style ones. If yours is a basket model, start checking at the low end. I keep more of these in my air fryer charts and tips if you want times for other vegetables.

Pro Tips

• Soaking is optional here. Soaking removes starch and helps with cut potatoes, but whole thin-skinned fingerlings don’t really need it — and then you have to dry them all over again.
• Dry them like you mean it. Wet potatoes steam instead of roasting. Pat them down with a towel after scrubbing — this is the single biggest difference between crispy and disappointing.
• Don’t crowd the basket. Potatoes need air on all sides. Two thin batches beat one packed one every time.
• Cut side down. If you halve them, start face-down. That’s where the crust forms.
• Salt at the start, not the end. Salt on the skin during cooking draws out surface moisture and helps it crisp.
• Shake once, not constantly. Every time you pull the basket you drop the temperature. One shake is enough.
• Preheat if you have time. Three to five minutes gets you a better skin. It’s not mandatory.

Variations

Once the base is working, the seasoning is wide open:

• Garlic and herb — the full version with fresh garlic, rosemary, and thyme is right here, including how to keep the garlic from burning.
• Rosemary — a teaspoon of chopped fresh rosemary in the oil toss. See my air fryer rosemary roasted potatoes.
• Parmesan — grated parmesan tossed on in the last two minutes, so it melts instead of scorching. Same idea as my garlic parmesan roasted potatoes.
• Ranch — a tablespoon of dry ranch seasoning in the oil.
• Smoky — smoked paprika and a pinch of cayenne.
• Dipping — garlic aioli, BBQ sauce, or sour cream and chives.

Substitutions

No fingerlings? These all work with the same method — just match the chart above to the size:

• Baby potatoes or new potatoes — closest swap, cook whole. Small waxy potatoes are also what make Syracuse salted potatoes work.
• Small red potatoes — waxy like fingerlings, halve if larger than 2″
• Yukon Golds — quarter them, slightly fluffier interior. They’re the potato I reach for in gold ranch potatoes.
• Russets — not recommended whole; too dense and starchy for this timing. Save them for roasted baked potatoes with sour cream and chives.

Frequently Asked Questions

Do you have to peel fingerling potatoes? No. The skin is thin, edible, and it’s the best part — it’s where all the crispness and most of the seasoning lives. Peeling them would defeat the entire recipe. Just scrub them.

What do fingerling potatoes taste like? Nutty, faintly sweet, and rich enough that you don’t need to add butter. Roasting concentrates that. They’re noticeably less starchy and more buttery than a russet.

Are fingerling potatoes healthy? They’re a good source of vitamin C, potassium, and fiber, and the skin carries a lot of that. Air frying uses about two tablespoons of oil for two pounds of potatoes, which is a fraction of what deep frying or heavy oven-roasting takes.

Do I need to preheat the air fryer? It helps but it isn’t required. Preheating for 3–5 minutes gives you a slightly better skin. If you skip it, add a minute or two to the cook time.

Can I add other vegetables to the basket? Yes, as long as they cook in a similar time — onion wedges, bell peppers, and broccoli florets all work. Add quick-cooking vegetables partway through rather than at the start.

How do I store and reheat leftovers? Airtight container in the fridge for 3 to 4 days. Reheat at 375°F in the air fryer for 3–4 minutes — they come back genuinely crispy, which is not something a microwave will do for you.

Can I use frozen potatoes? Not for this. Frozen potatoes carry too much moisture and you’ll steam them instead of roasting them.
