Deep-fried potato slices are hard to beat, but they come with a lot of oil and a lot of cleanup. This recipe gets close to that same golden, crunchy exterior and soft interior using an air fryer and a fraction of the oil. The technique leans on a few simple principles — thin, even slicing, a soak to pull out excess starch, and thorough drying before seasoning — that together do most of the work in getting these potatoes properly crispy rather than soft or steamed.

It’s a flexible side dish that works across meals, from breakfast to dinner, and it’s easy to season in different directions depending on what flavor profile you’re after.

Mise En Place: Getting Organized Before You Cook

This recipe has a soaking step built into the middle of it, so planning around that timing helps keep things efficient.

The potatoes. 2 to 3 medium potatoes — russet for extra crispiness, Yukon gold for a more buttery flavor, or red potatoes for a softer texture.

The seasoning. Olive oil, salt, black pepper, and any optional seasonings you want to add, like garlic powder, paprika, rosemary, or chili flakes.

Equipment. A sharp knife or mandoline slicer for even slices, a large bowl for soaking, a clean kitchen towel or paper towels for drying, a large mixing bowl for seasoning, and an air fryer.

Since the potatoes need to soak for 15 to 20 minutes partway through the process, this is a good point to prep your seasonings or get other parts of the meal going while you wait.

Workflow: How the Process Flows

1. Prepare the potatoes. Wash them thoroughly, peel if you prefer (or leave the skins on for extra texture), and slice into thin rounds, about ⅛ inch thick. A mandoline slicer gives more even thickness than a knife, which helps the slices cook uniformly.
2. Soak to remove starch. Place the slices in a large bowl of cold water and let them soak for 15 to 20 minutes.
3. Drain and dry thoroughly. Drain the water and pat the slices completely dry with a clean towel or paper towels.
4. Season the slices. Transfer the dried slices to a mixing bowl, drizzle with olive oil, and sprinkle with salt, pepper, and any optional seasonings. Toss until every slice is evenly coated.
5. Preheat and arrange. Preheat the air fryer to 375°F (190°C) if needed, then arrange the seasoned slices in the basket in a single layer, avoiding overcrowding.
6. Air fry until golden. Cook for 15 to 18 minutes, flipping halfway through for even browning on both sides.
7. Serve. Remove once golden brown and crispy, and serve immediately, on their own or with a dipping sauce.

Why Soaking and Drying Are the Real Secret

Soaking in cold water pulls excess starch out of the potato slices. That starch is what causes slices to stick together and turn gummy rather than crisp, so removing it before cooking is a big part of what makes these potatoes crunch properly in the air fryer instead of coming out soft.

Drying thoroughly afterward is just as important as the soak itself. Any leftover moisture on the surface of the slices will turn to steam once they hit the hot air fryer, and that steam works against crisping — it’s the difference between a potato slice that browns and one that stays pale and slightly soft no matter how long you cook it. Taking the extra minute to pat the slices completely dry with a towel is a small step that has an outsized effect on the final texture.

Why Slice Thickness and Spacing Matter

Slicing the potatoes to an even thickness — about ⅛ inch — means every piece cooks at roughly the same rate, so you’re not left with some slices burnt and others undercooked in the same batch. A mandoline slicer makes this more consistent than a knife, though a steady hand with a sharp knife works fine too.

Once the slices are in the air fryer, spacing matters just as much as thickness. Air needs to circulate freely around each piece for it to crisp evenly — slices that overlap or touch block that airflow in the spots where they’re in contact, leading to uneven browning. If you’re making a larger batch than fits comfortably in a single layer, cooking in multiple rounds gets a better result than cramming everything in at once.

Approved Seasoning Directions

The base seasoning here — olive oil, salt, and pepper — is intentionally simple, which makes it easy to build in other directions:

• Garlic powder for a savory, aromatic edge
• Paprika (or smoked paprika) for a warm, slightly smoky flavor reminiscent of barbecue seasoning
• Rosemary for an herby, slightly piney note
• Chili flakes for a bit of heat

Any of these can be added on their own or combined, depending on the flavor direction you’re going for.

Finishing Touches After Cooking

Once the potato slices come out of the air fryer, a few finishing touches can add another layer of flavor without changing the cooking process at all: fresh parsley, fresh thyme, or a sprinkle of Parmesan cheese, added right after cooking while the slices are still hot enough for the cheese to soften slightly against them.

Serving Suggestions

These potatoes are good enough to eat on their own, but they also pair well with a dipping sauce — ketchup, garlic aioli, ranch dressing, or whatever you typically reach for with a crispy potato side.

What Happens If You Skip the Soak

If you’re short on time, it’s possible to skip the soaking step entirely, but the trade-off is a less crispy final result. The starch that the soak would have removed stays in the slices, which makes it harder for them to develop the same crunchy exterior — so this is a reasonable shortcut on a rushed day, just with a noticeably different texture outcome than the full method.

Storage and Reheating

Leftovers can be stored in the refrigerator and reheated in the air fryer for 3 to 4 minutes to bring back the crunch, rather than relying on a microwave, which tends to leave previously-crispy foods soft.

Crispy Air Fryer Sliced Potatoes

Description: Thinly sliced, perfectly seasoned potatoes that cook to crispy, golden perfection in the air fryer while staying soft and fluffy inside — a lighter, hassle-free alternative to deep-frying.

Duration:

• Prep Time: 10 minutes
• Soak Time: 15–20 minutes
• Cook Time: 15–18 minutes
• Total Time: 30–35 minutes
• Servings: 2–3

Ingredients:

• 2–3 medium potatoes (russet for extra crispiness, Yukon gold for a buttery taste, or red potatoes for a softer texture)
• 1–2 tablespoons olive oil
• ½ teaspoon salt
• ¼ teaspoon black pepper
• Optional seasonings: garlic powder, paprika, rosemary, or chili flakes

Instructions:

1. Wash the potatoes thoroughly. Peel if desired, then slice into thin rounds, about ⅛ inch thick.
2. Place the slices in a large bowl of cold water and soak for 15–20 minutes to remove excess starch.
3. Drain and pat the potato slices completely dry with a clean kitchen towel or paper towels.
4. Transfer to a large mixing bowl. Drizzle with olive oil, then sprinkle with salt, pepper, and any optional seasonings. Toss until evenly coated.
5. Preheat the air fryer to 375°F (190°C) if needed. Arrange the slices in the basket in a single layer, avoiding overcrowding. Cook in multiple batches if needed.
6. Air fry for 15–18 minutes, flipping halfway through for even browning.
7. Remove once golden brown and crispy. Serve immediately, plain or with a dipping sauce.

Notes:

• Soaking removes excess starch and is key to achieving a crispy texture; skipping it will still work, but with a less crispy result.
• Dry the potato slices completely before seasoning — leftover moisture causes steaming instead of crisping.
• Don’t overcrowd the air fryer basket; air circulation is essential for even crisping.
• Store leftovers in the fridge and reheat in the air fryer for 3–4 minutes to restore crunch.
