Flammkuchen is Alsace’s answer to pizza, only thinner, crisper and completely without tomato sauce. The base is paper-thin, the topping is crème fraîche, finely sliced onion and salty diced bacon, and the rest is about high heat and a short time. That is exactly what an air fryer is good at: the concentrated heat and the powerful air circulation give you those bubbling, lightly charred edges that otherwise need a stone oven.

I have made flammkuchen countless times in the air fryer, and the result comes closer to the original from an Alsatian wine tavern than anything I have got out of an ordinary oven. Here you get the method, the mistakes I made along the way and the adjustments that made the difference.

Why I love flammkuchen in the air fryer
Flammkuchen has only four things on the base, so there is nowhere to hide: it has to be crisp all the way out, not just at the edge. An air fryer hits 200 °C in under a minute and holds the temperature steady while the air is pushed down over the topping. That dries the surface quickly enough for the onion to take colour without the base going soft along the way.
The small basket is an advantage, not a limitation. A flammkuchen the size of the bottom of the basket is done while you roll out the next one, and you can serve them one at a time, while they are at their hottest. That is exactly the way the dish was originally eaten in Alsace.
The difference between an air fryer and an oven
An ordinary oven takes a long time to come up to temperature, and the heat drops every time the door is opened. The air fryer heats the basket from below and at the same time blows hot air down from above, so the base sets before the topping releases its liquid. That is also why an air fryer typically handles baking 20 to 30 per cent faster than an oven at the same temperature, and with flammkuchen, where seconds decide whether the edge is golden or black, that control means everything.
My kitchen test: flammkuchen
I have made this version in my Cosori Dual Blaze at 200 °C, and the recipe has ended up at 90 minutes from start to last piece: 20 minutes of preparation, 30 minutes of resting time for the dough and 40 minutes of cooking in total. The resting time is the step I most often see people skip, and it is also the one that makes the biggest difference — a rested dough lets itself be rolled paper-thin without shrinking back again.
I have also tried turning up the heat to speed things along. The edge went dark before the crème fraîche had set, and the onion tasted burnt rather than sweet. 200 °C is the point where the base, the topping and the onion are done at the same time, and that is why the number is not up for negotiation.
Roll the dough thinner than you think is sensible. If you can just make out the worktop through it, you have hit the right thickness — it ends up a touch thicker in the air fryer anyway.
Tips and tricks from the author: Morten Jensen
The typical mistakes and how to avoid them
The first and biggest mistake is too thick a base. Flammkuchen is not pizza, and a couple of millimetres too much turns crispness into bread. Roll the dough out on baking paper so you can lift it into the basket without pulling it out of shape. The second mistake is too much crème fraîche. A thin layer you can just make out the dough through is plenty — pour it on as if it were tomato sauce and the base steams from the inside and never goes crisp. The third mistake is too generous a topping. The onion has to be sliced finely, and the diced bacon should lie scattered rather than in a layer. Push it too far and the temperature in the basket drops, and you end up with boiled onion on top of soft dough.
How to serve flammkuchen
Flammkuchen is eaten with your fingers, cut into squares and shared straight away. It does not tolerate waiting, so put the accompaniments on the table before the first one comes out of the basket.
- A dry riesling or a light pinot blanc from Alsace
- A green salad with a sharp mustard vinaigrette
- Freshly snipped chives or coarsely ground pepper over the topping
- Pickled red onion that cuts through the richness of the bacon
Storage and reheating
Flammkuchen is at its best within the first few minutes, but leftovers can easily be rescued. Keep them in the fridge under a tea towel or loose foil for up to two days, never in an airtight container, where the condensation softens the base. Reheat them for a couple of minutes in the air fryer at a slightly lower temperature than the baking, until the edge is crisp again. The microwave ruins the dish completely and should be kept well out of the equation.
Flammkuchen in the air fryer is one of those dishes where technique counts for more than the shopping list. Roll the base thin enough, go easy on the crème fraîche and let the air fryer work at full blast, and you get a result that rivals a real flammkuchen from a wood-fired oven.
Frequently asked questions
No, the dough does not need to rise like a pizza dough, but it does need to rest. The recipe gives it 30 minutes of resting time so the gluten relaxes and the dough can be rolled paper-thin without shrinking back again.
You can, but then you get a thin pizza rather than a flammkuchen. Pizza dough contains yeast and rises in the heat, so the base turns airy instead of crisp. If you want to get close to the original, use the yeast-free dough from the recipe.
Almost always because the base has been rolled too thick, or because too much crème fraîche has gone on. Both hold on to the moisture. Roll it thinner, spread on a thin layer, and make sure the air fryer is heated all the way up to 200 °C before the base goes into the basket.

Ingredients
Dough
- 250 g plain flour
- 1 tsp salt
- 2 tbsp olive oil
- 125 ml water (Lukewarm)
Topping
- 200 g crème fraîche (18 %)
- 2 pcs onion (Thinly sliced into half-rings)
- 150 g bacon (Diced)
- 1 pinch grated nutmeg
- 0.5 tsp salt
- 0.5 tsp black pepper (Freshly ground)
- 2 tbsp chives (Finely chopped, to garnish)
How to make it
Dough
- Mix 250 g plain flour and 1 tsp salt in a mixing bowl. Add 2 tbsp olive oil and 125 ml water, and bring it together into a cohesive dough with a fork.
- Knead the dough on a lightly floured worktop for 3-4 minutes, until it is smooth and supple. The dough contains no yeast, so it does not need to rise.
- Cover the dough with a tea towel and leave it to rest for 30 minutes at room temperature. The rest relaxes the gluten, so the dough can be rolled paper-thin without shrinking back.
Topping
- Stir 200 g crème fraîche together with 1 pinch grated nutmeg, 0.5 tsp salt and 0.5 tsp black pepper.
- Peel and slice 2 pcs onion into thin half-rings, and cut 150 g bacon into cubes.
Cooking in the air fryer
- Preheat the air fryer to 200 °C on the fan setting.
- Divide the dough into four equal pieces. Roll one piece out paper-thin — 1-2 mm — straight onto a piece of baking paper, and trim the paper so it fits the air fryer basket.
- Spread a thin layer of the crème fraîche mixture over the dough, leaving a border of about 1 cm clear. Scatter the onion and bacon evenly over the top.
- Lift the flammkuchen into the preheated air fryer on the baking paper and bake at 200 °C for 8-10 minutes, until the edge is golden brown and the bacon is crisp. Bake one at a time, and repeat with the rest of the dough.
Serving
- Scatter 2 tbsp chives over the top and serve the flammkuchen straight away, cut into strips or triangles.
Our notes for the recipe
Roll the dough as thin as you can — 1-2 mm. It is the thickness, not the time in the air fryer, that decides whether the base turns out crisp or chewy. Keep the topping in a thin layer as well, so the moisture can escape instead of softening the dough. Variation:
Swap the bacon for thin slices of chorizo, or make a vegetarian version with button mushrooms and spring onions. A handful of grated Gruyère for the last 3 minutes gives you a richer version. Serving:
Serve the flammkuchen straight from the air fryer, cut into strips, with a green salad on the side. In Alsace it is classically enjoyed with a glass of dry riesling. Portion size:
The four small flammkuchen are baked one at a time, so allow about 10 minutes each. Feel free to eat them as they come, while they are at their crispest.
