Air Fryer Recipe
Parmesan Truffle Chips
Crispy and flavourful, Parmesan truffle chips are a gourmet snack easily made in an air fryer.
Ingredients
- 500g potatoes (Maris Piper or King Edward)
- 2 tablespoons truffle oil
- 50g grated Parmesan cheese
- Salt
- Freshly ground black pepper
- 1 tablespoon finely chopped fresh thyme (optional)
Method
- Preheat air fryer to 200°C (390°F).
- Wash and peel potatoes, then slice thinly using a mandoline or sharp knife.
- Place sliced potatoes in a bowl and add truffle oil, salt, black pepper, and thyme. Toss to coat.
- Spread potato slices in a single layer in the air fryer basket.
- Cook for 15-20 minutes, shaking the basket halfway through.
- Remove chips from air fryer and sprinkle with Parmesan while hot.
- Serve immediately.
Why this works in an air fryer
Thin potato slices crisp because the air fryer drives off surface moisture quickly while a small amount of oil improves heat transfer and browning. Parmesan is added after cooking so its low-moisture proteins soften onto the hot chips without burning, and truffle oil stays aromatic rather than being dulled by prolonged heat.
Equipment notes
Assumes a 4–5 litre basket holding 500g potatoes in 2–3 thin batches; true single-layer spacing matters more than total cook time. In a single-drawer model, cook batches sequentially and keep finished chips uncovered. In a dual-zone fryer, split evenly and rotate drawers or swap positions halfway if one side browns faster.
Common pitfalls
- Chips bend rather than snap at 15 minutes? The slices are too wet or thick; pat them dry thoroughly and continue in 2-minute bursts, removing any already-crisp pieces.
- Edges dark but centres leathery? The mandoline thickness is uneven or the temperature is too high for the batch; cut to about 1–2mm and drop to 180°C for the remaining time.
- Parmesan turns grainy or bitter? It was added before air frying or while the chips were too oily; sprinkle it on only after cooking, then toss lightly off the heat.
- Pale patches where slices overlap? The basket is overcrowded; cook fewer slices per batch and shake with tongs to separate any stuck pieces halfway through.
Variations & substitutions
- Use Pecorino instead of Parmesan for a saltier, sharper finish; reduce added salt because it seasons more aggressively.
- Swap thyme for rosemary, chopped very finely; rosemary is more resinous, so use less to avoid dominating the truffle aroma.
- Use sweet potatoes for a sweeter version, but cook at 180°C and expect a slightly softer chip because they contain more sugar and less starch.
- Replace some truffle oil with neutral rapeseed oil if the flavour is too strong; add a final drizzle of truffle oil after cooking to keep the aroma clean.
Storage & reheating
Best eaten straight away, but leftovers keep for up to 2 days in an airtight container and can be re-crisped in the air fryer at 180°C for 3–5 minutes.
