Parmesan crisps are the kind of dish where a single ingredient transforms into something completely different. A small pile of finely grated Parmesan turns into crunchy, golden flakes in the air fryer in under ten minutes — no oil, no flour, no deep frying. The result is salty, umami-rich crisps that can stand alone as a snack or be used as an accompaniment to soup, salad and a glass of red wine.

The secret is in the cheese. Use real Parmigiano Reggiano or Grana Padano, and grate it yourself on a fine grater. Pre-grated cheese from a bag often contains starch or anti-caking agents, which give a greasy and chewy result instead of the sharp crispiness you’re after.

Why I love Parmesan crisps in the air fryer
It’s one of the few dishes that requires only one ingredient and five or six minutes in the air fryer. It’s hard to find a faster snack for a small craving, and when guests arrive you can pop a batch in while you finish other things in the kitchen.
The air fryer gives a more even melting and browning than both the oven and the frying pan. The cheese bubbles and browns evenly without hot spots, and because there’s no long preheating, you save minutes compared to a regular oven.
The difference between air fryer and oven
In the oven, Parmesan crisps typically take 8-10 minutes at 200 °C, and the result is often uneven — the edge browns quickly while the centre is still soft. The air fryer’s circulating heat hits every crisp from all sides, so you get even colour and texture in 5-6 minutes. You also save a long preheat.
My kitchen test of Parmesan crisps
I’ve tested Parmesan crisps in my Cosori Dual Blaze at 180 °C for 5-6 minutes, and that’s the sweet spot. At 200 °C the edge turned slightly bitter, and at 170 °C the crispiness didn’t quite come into its own. I lined the basket with baking paper and spread small mounds of finely grated Parmesan with good spacing — two tablespoons per crisp gives a size that can be lifted without breaking.
The perfect crisp is golden at the edge with a slightly lighter centre, crunchy at the first bite and then melting on the tongue. If you have a larger air fryer like the Philips XXL, you can easily make a whole batch at once by lining the entire basket bottom with baking paper and spreading 8-10 mounds in an open pattern.
The most important thing is to let the crisps cool completely in the basket before you move them. Warm, they’re soft, but once cooled the crispiness is locked in — move them too early and they crack or turn chewy.
Tips and tricks from the author: Morten Jensen
The typical mistakes and how to avoid them
The most common mistake is using pre-grated Parmesan from a bag. The starch in the pre-grated cheese prevents the crisp from melting together into a firm disc, and you end up with a soft, crumbling lump instead of the characteristic flake. Always grate your own from a piece. The second mistake is making mounds that are too big — two tablespoons per crisp is the max, otherwise the centre doesn’t melt evenly and you get thick, chewy spots. Finally: never skip the baking paper. Parmesan burns onto the basket and is almost impossible to get off without paper underneath.
How to serve Parmesan crisps
They’re wonderfully versatile and fit into many dishes. A couple of favourite suggestions from my own kitchen:
- As a topping on a classic Caesar salad
- Crushed over hot tomato soup just before serving
- As a snack with a glass of red wine or an Aperol Spritz
- Together with a mild dip such as tzatziki or homemade pesto mayonnaise
- Broken into flakes over a creamy pasta carbonara
Storage and reheating
Cooled crisps can be stored in an airtight container at room temperature for up to 3 days. Put a piece of kitchen paper in the bottom — it soaks up excess fat and keeps them crisp. They shouldn’t go in the fridge, as the moisture there makes them soft. If they lose their crispiness, you can give them 90 seconds at 160 °C in the air fryer, and they’re fresh and crunchy again.
Parmesan crisps are the kind of one-trick pony that stands strong precisely because it’s simple. Few ingredients, little time, a crunchy result — and a dish you’ll rarely regret.
FAQ
Yes, hard matured cheeses such as Grana Padano or Pecorino Romano work fine. Avoid soft cheeses like mozzarella, as they release too much moisture and don’t turn crisp.
Yes, baking paper is strongly recommended. Without it the cheese burns onto the basket and is almost impossible to remove without the crisp breaking.
In an airtight container at room temperature they stay crisp for up to 3 days. Put a piece of kitchen paper in the bottom to soak up excess fat.

How to make it
Preparation
- Preheat the air fryer to 200 °C (fan).
- Finely grate 200 g Parmesan into a bowl and mix with 0.5 tsp paprika and 0.25 tsp freshly ground black pepper.
- Cut a piece of baking paper to fit the air fryer basket.
Cooking in the air fryer
- Place small mounds of the Parmesan mixture (about 1 tbsp per crisp) on the baking paper, leaving plenty of space between them.
- Gently press each mound flat with the back of a spoon so they form round crisps.
- Bake in the air fryer at 200 °C for 5-6 minutes, until the crisps are golden and the bubbles have disappeared.
Serving
- Let the crisps cool completely on the baking paper — they only become really crisp once they have cooled down.
- Serve as a side with soup, salad or as a low-carb snack with a good dip.
Our notes for the recipe
Use finely grated Parmesan — it produces more even, crispier crisps than coarsely grated cheese. Let the crisps cool completely on the baking paper before you move them; they keep crisping up as they cool. Variation:
Add dried oregano, thyme or chilli flakes for extra flavour. You can also mix the Parmesan with grated pecorino for a stronger cheese flavour. Serving:
Serve the crisps with guacamole, hummus or fresh salsa, as a topping on creamy soups, or as a low-carb alternative to crackers on the cheese board. Extra crispiness:
For maximum crispiness, give the crisps 2-3 minutes extra at 180 °C after the main bake if they still seem soft in the middle.
