Air Fryer Smashed Potatoes: Crispy, Fluffy, No Boil
These air fryer smashed potatoes skip the stovetop boil and deliver genuinely craggy, crisp edges with a fluffy centre — all in about 30 minutes. A microwave par-cook does the heavy lifting so the air fryer can focus entirely on texture.

Smashed potatoes have one job: maximum surface area, maximum crisp. The oven version works well, but the air fryer gets those shattered edges golden faster without heating up the whole kitchen.
The method here skips the stovetop boil entirely. A quick microwave steam softens the potatoes in six minutes flat, and from there it’s a smash, a brush of oil, and 14 minutes in a preheated basket. This is the kind of side dish that comes together while the main is resting.

Worth Knowing Before You Cook
Uniformity is the one thing worth spending time on at the supermarket. If your potatoes vary significantly in size — say, some golf-ball-sized and some walnut-sized — the smaller ones will overcook before the larger ones are tender enough to smash cleanly. Aim for baby potatoes roughly 30–40g each. If your bag has a mix, pull out the outliers and save them for something else.
Ingredients
Equipment
Method
- Pierce each potato 4–6 times with a fork. This lets steam escape during the microwave step.
- Place the potatoes in a microwave-safe bowl with 2 tbsp water. Cover tightly and microwave on high for 5–6 minutes, until just tender when pierced. Start checking at 5 minutes.
- Uncover the bowl and rest the potatoes uncovered for 2 minutes so surface moisture can escape.
- Preheat the air fryer to 200°C (400°F) while the potatoes rest.
- Transfer the potatoes to a cutting board. Press each one firmly with the flat base of a mug until it forms a disc roughly 1/2 inch (1.3 cm) thick. Cracked, craggy edges are what you want.
- Brush both sides of each smashed potato with olive oil, working it into the crevices. Season with salt and black pepper.
- Arrange the potatoes in a single uncrowded layer in the preheated basket. Do not shake. Air fry at 200°C (400°F) for 7 minutes.
- Flip each potato with a thin spatula. Air fry at 200°C (400°F) for a further 5 minutes, until deep golden.
- Scatter parmesan over the potatoes, if using, and air fry at 200°C (400°F) for a final 2 minutes, until melted and lightly crisp. Skip this step for plain smashed potatoes.
- Serve immediately, with a small sprinkle of finely chopped parsley if using. Smashed potatoes lose their crunch within a few minutes of sitting.
Notes
Why This Recipe Works
Smashing a potato does two things: it flattens it for maximum basket contact, and it shatters the surface into irregular ridges. Those ridges are where the crispness happens — they thin out at the edges, dry quickly in the air fryer’s circulating heat, and brown faster than a flat surface would.
- The microwave par-cook steams the potato from the inside out, making the centre genuinely fluffy before it hits the basket — no stovetop pot needed.
- The two-minute uncovered rest after microwaving lets surface moisture escape, so the potatoes arrive in the basket dry and browning starts immediately.
- Preheating the basket and skipping the shake let the crust set undisturbed — interrupting it early breaks the crust rather than building it.
Pro Tips
- Use uniform baby potatoes around 30–40g each — size variation is the most common cause of uneven results.
- Brush liquid olive oil rather than spraying; it gets into the crevices where browning actually happens.
- Don’t shake the basket before the flip at minute 7 — the crust needs to set undisturbed on the bottom first.
- Reheat leftovers in the air fryer at 200°C (400°F) for 4–5 minutes; avoid the microwave or the crunch won’t come back.
What Can Go Wrong
The potatoes are pale and soft after cooking
The basket likely wasn’t preheated, or the potatoes were still wet from the microwave. Always preheat fully before loading, and extend the steam-dry rest to 3 minutes if the potatoes were steaming heavily when you uncovered the bowl.
The potatoes crumbled during smashing
Overcooking in the microwave made the flesh too soft to hold shape under pressure. Reduce microwave time by 30–45 seconds and check at 5 minutes — press gently with a finger; the skin should give but the potato should still hold its form.
The crust broke apart during the flip
Flipping too early before the crust had fully set. At minute 7, slide a thin spatula under one potato to test — if it releases cleanly, it’s ready. If it sticks, give it another minute before flipping the rest.
The parmesan burned rather than crisped
It was added too early in the cook. Parmesan goes on only in the last 2 minutes — adding it before that exposes it to too much dry heat and it scorches rather than forming light crisp patches.
Storage & Reheating
Cool completely before storing. Keep in an airtight container in the fridge for up to 3 days — the crunch will soften as they sit. Freezing is not recommended; the texture of cooked waxy potatoes breaks down after freezing and thawing, and the crust will not re-crisp on reheating.
Reheat in the air fryer at 200°C (400°F) for 4–5 minutes from fridge temperature. No need to add more oil; the residual oil from the original cook is enough to re-crisp the edges. Avoid the microwave — it steams them and the crunch won’t return.

FAQ
Do I really need to microwave the potatoes first?
Yes — the microwave par-cook is what makes the centre fluffy without boiling. Without it, the potato interior stays dense and the skin won’t smash cleanly to a half-inch disc. Six minutes on high with 2 tablespoons of water in a covered bowl is enough to do the work.
Can I skip the 2-minute rest after microwaving?
It’s a short step but worth doing. The rest lets surface moisture escape before the potatoes go into the basket. Skipping it means they arrive steaming, which stalls browning and reduces crispness on the underside.
Why shouldn’t I shake the basket during cooking?
Shaking breaks the crust on the underside before it has set. Leaving the potatoes undisturbed for the full 7 minutes allows the bottom to build a solid, even crust that holds together cleanly when you flip.

Basket-Style Air Fryer
A standard basket-style air fryer works well here — the circulating heat is what drives the crisp on those shattered edges. See our best air fryer overall pick if you are still choosing a model.
Flat-Bottomed Mug
Used for smashing. A flat base gives even, controlled pressure — a rounded base tends to crack potatoes unevenly. The back of a wide spatula also works in a pinch.
Silicone Pastry Brush
Brushing liquid olive oil gives better coverage than spraying, especially into the craggy edges where browning happens. A silicone brush is easiest to clean.
