Chicken Wellington is the lighter little brother of the classic Beef Wellington. A whole chicken breast is wrapped in a layer of fried mushrooms and fresh herbs, rolled in golden puff pastry and baked until the crust crackles. In the air fryer the pastry gets exactly the dry, circulating heat it loves, and the result is crisper all the way round than in a conventional oven.

The whole dish takes 72 minutes from the moment you start until it is on the table, and most of that time is passive prep and chilling time. It is a dish that looks far more complicated than it is – and that is exactly why it is so rewarding to serve to guests.

Why I love Chicken Wellington in the air fryer
Puff pastry lives on dry heat, and that is exactly what an air fryer delivers. The air circulates around the whole parcel, so the base gets just as crisp as the top. That is the classic weakness of Chicken Wellington in the oven, where the base often ends up soggy from the steam that collects on the baking tray. At 180 °C the pastry browns evenly, while the chicken breast inside steams gently in its own juices under the layer of mushrooms.
There is also an advantage when it comes to portions. One Wellington fills an air fryer basket exactly, and you avoid heating a whole oven for a couple of servings. The cooking itself takes 22 minutes – the rest of the 72 minutes is prep and the chilling time that makes the pastry hold its shape.
The difference between Chicken Wellington and chicken in puff pastry
Chicken in puff pastry covers just about anything wrapped in dough: shredded chicken with cream cheese, fillet with bacon, yesterday’s leftovers. Chicken Wellington is the precise version. Here a finely chopped mushroom filling sits as a dry, concentrated layer between the meat and the pastry, and the herbs – usually thyme and parsley – are part of the definition, not a garnish. It is the mushroom layer that makes the dish a Wellington rather than just chicken in puff pastry.
My kitchen test of Chicken Wellington
I have tested my Chicken Wellington in a Philips XXL, where there is room for the whole parcel without it touching the sides of the basket. 180 °C for 22 minutes is the point I keep coming back to: the pastry reaches a deep golden brown, and the core temperature in the chicken hits 75 °C. If I turn the heat up higher, the crust is dark long before the meat is done.
The 20 minutes of chilling time before cooking are not up for negotiation. I have tried skipping them, and the parcel split at the seam, so the mushroom filling ran out into the basket. With cold pastry the roll holds its shape all the way through. Reckon on 30 minutes of prep, so the mushroom filling has time to cool before it meets the puff pastry.
Fry the mushrooms until all the liquid has evaporated, and let them cool completely. Wet mushroom filling is the only reason a Wellington ends up soggy on the bottom.
Tips and tricks from the author: Morten Jensen
The typical mistakes and how to avoid them
The first and biggest mistake is wet mushroom filling. Mushrooms consist almost entirely of water, and if that water is not fried out, it ends up in the pastry. Fry them in the frying pan until the sound goes from sizzling to quiet, and let them cool on a plate. The second mistake is skipping the chilling time. Puff pastry made with soft butter goes limp the moment it meets hot air, and the parcel opens up – twenty minutes in the fridge makes it rise in layers instead. The third mistake is turning the heat up to save time. Above 180 °C the crust is dark long before the chicken has reached 75 °C in the middle, and you end up with a good-looking surface over meat that is not cooked through. A meat thermometer in the thickest part is the only reliable measurement.
How to serve Chicken Wellington
The dish is rich in itself, so the sides can happily pull in a fresh, sharp direction:
- A rich cream sauce with thyme or a classic Madeira sauce
- Small potatoes or roast root vegetables in the air fryer while the Wellington rests
- Green beans or broccoli tossed with lemon
- A crisp salad with a sharp vinaigrette that cuts through the puff pastry
Storage and reheating
Leftovers keep covered in the fridge and are reheated in the air fryer at a moderate heat until the pastry is crisp again. The microwave turns the puff pastry tough and soggy in seconds, and there is no saving it afterwards. You can also assemble the whole parcel the day before and leave it covered in the fridge until it goes into the basket – cold pastry is an advantage, not a drawback.
Chicken Wellington rewards patience rather than technique. If the mushroom filling is allowed to cool, and the pastry gets its 20 minutes in the fridge, the air fryer handles the rest in 22 minutes. Serve it whole at the table and carve it in front of your guests – that is half the fun.
FAQ
22 minutes at 180 °C. If you count prep and chilling time, the dish takes 72 minutes in total. The chicken is done when the core temperature hits 75 °C in the thickest part.
Chicken in puff pastry is a general term for all chicken wrapped in dough. Chicken Wellington is the classic version with a layer of fried mushrooms and fresh herbs between the meat and the puff pastry – the mushroom layer is the very definition.
Yes. Assemble the whole parcel, wrap it tightly and leave it in the fridge until serving. Cold puff pastry holds its shape better in the air fryer, so it is an advantage rather than a drawback.

Ingredients
Chicken
- 4 pcs chicken breast fillets (About 150 g each)
- 1 tsp salt
- 0.5 tsp freshly ground pepper
- 1 tbsp olive oil (For browning)
Mushroom filling
- 300 g button mushrooms (Finely chopped)
- 1 pcs shallot (Finely chopped)
- 2 clove garlic (Finely chopped)
- 25 g butter
- 1 tbsp fresh thyme (Finely chopped)
- 2 tbsp fresh parsley (Finely chopped)
- 0.5 tsp salt (For the filling)
Assembly
- 4 pcs puff pastry sheets (Thawed)
- 8 slice Parma ham
- 2 tbsp Dijon mustard
- 1 pcs egg (For brushing)
How to make it
Preparation
- Chop 300 g button mushrooms, 1 pcs shallot and 2 clove garlic very finely. The finer the chop, the denser and more even the mushroom filling becomes.
- Fry the mushroom mixture in 25 g butter in a frying pan over a medium heat for 8-10 minutes, until all the moisture has evaporated and the mixture is dark and dry.
- Add 1 tbsp fresh thyme, 2 tbsp fresh parsley and 0.5 tsp salt. Stir and take the pan off the heat.
- Season 4 pcs chicken breast fillets on all sides with 1 tsp salt and 0.5 tsp freshly ground pepper. Pat them dry with kitchen paper first, so the seasoning sticks.
- Heat 1 tbsp olive oil in the frying pan over a high heat and brown the chicken breasts for 1-2 minutes on each side, so they take on colour. They should not be cooked through at this stage.
- Leave both the mushroom filling and the chicken to cool completely, at least 10 minutes. Warm filling melts the puff pastry and gives you a soggy base.
Assembly
- Spread 2 tbsp Dijon mustard in a thin layer in the middle of 4 pcs puff pastry sheets, which you have unrolled on a cutting board.
- Lay 8 slice Parma ham on top of the mustard, two slices per sheet, and spread the mushroom filling evenly over them.
- Wrap the puff pastry tightly around one chicken breast per sheet. Press the edges firmly together and turn the parcels over so the seam faces down.
- Prick two or three small holes in the top of each parcel with a sharp knife, so the steam can escape during baking.
- Brush the whole surface of the parcels with 1 pcs egg, lightly beaten, so the puff pastry bakes golden.
- Cover the parcels with cling film and chill them for 20 minutes. Cold puff pastry rises better and holds its shape in the air fryer.
Cooking in the air fryer
- Preheat the air fryer to 180 °C fan.
- Line the basket with baking paper for air fryers, so the puff pastry does not stick.
- Bake two parcels at a time at 180 °C for 20-22 minutes, leaving plenty of space between them. Do not turn them over during baking — instead rotate them half a turn after 12 minutes, so they brown evenly.
- Check the core temperature with a meat thermometer. The chicken should be 75 °C in the middle. Give it another 2-4 minutes at 180 °C if it is not there yet.
- Repeat with the last two parcels, keeping the first ones warm under foil in the meantime.
Serving
- Serve the parcels after 5 minutes’ resting — whole or cut on the diagonal, so the layers of puff pastry, Parma ham, mushroom filling and chicken stand out.
Our notes for the recipe
The mushroom filling must be completely dry and completely cold before it meets the puff pastry. Steam from warm filling is the most common reason a Wellington turns out soggy on the bottom. Variation:
Swap the Parma ham for thin slices of bacon, or stir 50 g cream cheese into the mushroom filling for a creamier result. If you want to serve Chicken Wellington as a starter, cut each chicken breast in two and make eight smaller parcels — baking time about 14-16 minutes. Serving:
Serve with a cream or red wine sauce, steamed green beans and small roast potatoes. Chicken Wellington or chicken in puff pastry?
Chicken Wellington is the classic Wellington version with a mushroom duxelles, a layer of ham and puff pastry all the way round. Plain chicken in puff pastry is a simpler dish, where the chicken is usually wrapped in puff pastry with cheese or pesto, without the mushroom filling and the layer of ham. Portion size:
If you have a large air fryer, you can bake all four parcels at once — but they must not touch each other, or the puff pastry will not crisp up all the way round.
