These are simple potato slices cooked in the air fryer until crispy on the outside and soft on the inside, meant to stand in for chips or fries as a quick, easy side dish. The base recipe uses just potatoes, oil, and salt, but it’s built to be dressed up with different seasonings depending on what flavor direction you’re in the mood for. Because the air fryer heats up faster and uses less power than a full oven, this is a genuinely quick side dish option, especially useful for busy weeknights or when you don’t want to run a full oven just for a side.
The recipe takes about 30 minutes total, most of which is hands-off cooking time, and the potato variety and slice thickness both play a real role in how crispy and evenly cooked the final result turns out. Because air fryers are smaller and heat up more quickly than conventional ovens, this method also tends to use less energy overall, which is part of the appeal for anyone cooking a simple side on a regular basis rather than as an occasional treat.
Getting Everything Ready
Because slice thickness and potato variety both affect cooking time and texture, choosing the right potato and cutting it consistently matters more here than in many other air fryer recipes.
Equipment to have ready:
- An air fryer
- A knife, for slicing
- An air fryer liner (optional)
Ingredients to have ready:
- 500g potatoes
- 1 tablespoon sunflower oil
- 1 teaspoon sea salt
For the crispiest results, using the same kind of potato you’d choose for chips or fries is recommended — Maris Piper or King Edward in the UK, Estima, Melody, or Marfona as good all-rounders, or Yukon Gold in the US. New potatoes can also be used, but should be sliced thinner so they cook through in the same amount of time, since their different texture and moisture content behaves a bit differently under heat than a starchier chip-style potato.
Workflow: How the Process Comes Together
This recipe is a simple, linear process:
- Preheat the air fryer, if your model requires it.
- Slice the potatoes to an even thickness.
- Toss with oil and salt.
- Spread out in the basket, avoiding overcrowding.
- Air fry, turning gently halfway through.
- Serve hot.
Because these slices take up more space in the basket than smaller potato preparations, this recipe is one where checking your air fryer’s capacity ahead of time — and planning for batches if needed — saves you from having to stop and restart partway through cooking. Since the slices are thin and can burn quickly if left unattended, this is also a recipe where staying nearby during the cook time matters more than with thicker-cut potato dishes.
Approved Variations & Swaps
Based strictly on what’s built into this recipe, here are the adjustments it already allows for:
- Seasoning swap: beyond the classic oil-and-salt version, garlic, herby potato seasoning, Cajun, peri peri, Chinese-style salt and pepper, or light spices can all be used instead.
- Peeling is optional: leaving the skin on saves time and adds flavor, while peeling gives a different texture — and if you do peel them, the peelings themselves can be saved and turned into air fryer potato peel crisps.
- Potato variety: any of the chip-style potatoes listed above work well, or new potatoes sliced thinner to compensate for their different texture.
- Batch cooking: if your air fryer is small, slices can be cooked in batches and then reheated together at the end to serve everything warm at once.
- Liner use: an air fryer liner can be used for easier cleanup, though it may reduce how crispy the slices get, so it’s presented as an optional trade-off rather than a requirement.
No other ingredient substitutions are specified in the source recipe, so changes beyond these listed variations would go beyond what’s actually described here. Since the base recipe is intentionally minimal, nearly all of the customization potential lives in the seasoning choice and potato variety rather than in the technique itself, which stays the same regardless of which flavor direction you go with.
Step-by-Step Cooking Strategy
A handful of specific technique choices are what determine whether these potato slices turn out crispy and evenly cooked, or unevenly done and stuck together.
Slice to an even thickness, around 0.5 cm. Consistent thickness across all the slices is what allows them to cook at the same rate — thinner slices cook faster and crisp up more, but need to be watched closely since they can burn quickly at that thickness, especially toward the end of the cook time when they’re already mostly dried out.
Toss thoroughly with oil and salt before cooking. An even coating helps every slice crisp consistently, rather than some ending up drier or blander than others.
Don’t overcrowd the basket. These slices take up more room than other potato preparations because of their shape, so giving them space to lay out properly is what allows hot air to circulate and crisp each one. If you have a smaller air fryer, cooking in batches and combining everything at the end is the better approach than trying to force it all in at once.
Turn the slices gently halfway through cooking. This helps both sides crisp evenly, rather than leaving one side to cook longer than the other.
Toss the slices during cooking, not just at the halfway turn. This helps prevent the slices from sticking together, especially since they’re thin and can overlap more easily than thicker potato cuts.
Check a few minutes early if your air fryer runs hot. Since not every model needs preheating and some cook faster than others, keeping an eye on the potatoes slightly before the full cook time is up helps avoid overcooking, especially with thinner slices that can go from perfectly done to burnt quickly.
Serve immediately while hot. These slices are at their crispiest right out of the air fryer, similar to fries or chips, so serving them right away rather than letting them sit gives the best texture — like most fried or air-fried potato preparations, they’ll gradually soften as they cool, so timing them to finish right as the rest of the meal is ready is worth planning for.
Air Fryer Potato Slices
Description: Crispy, golden potato slices made easily in the air fryer. A perfect side dish with minimal oil and loads of flavor, ready to stand in for chips or fries with any meal.
Duration:
- Prep Time: 5 minutes
- Cook Time: 25 minutes
- Total Time: 30 minutes
Ingredients
- 500g potatoes
- 1 tablespoon sunflower oil
- 1 teaspoon sea salt
Instructions
- Preheat the air fryer, if your model requires it.
- Slice the potatoes into 0.5 cm thick rounds.
- Toss the slices with the oil and salt.
- Spread them out in the air fryer basket.
- Air fry at 200°C (392°F) for about 25 minutes, turning gently halfway through.
- Serve hot and enjoy.
Notes
- Thinner slices cook faster and crisp up more, but watch them closely — they can burn quickly.
- Don’t overcrowd the basket; cook in batches if your air fryer is small, then combine and reheat together at the end.
- Toss the slices during cooking to prevent them from sticking together.
- Leaving the skin on saves time and adds flavor; if peeling, save the peelings to make potato peel crisps separately.
- Good potato choices include Maris Piper, King Edward, Estima, Melody, Marfona, or Yukon Gold; new potatoes work too if sliced thinner.
- Try different seasonings beyond oil and salt, such as garlic, herby potato seasoning, Cajun, peri peri, Chinese-style salt and pepper, or light spices.
- An air fryer liner can be used for easier cleanup, though it may reduce crispiness.
