Small Chicken Wellington is the kind of dish that turns a perfectly ordinary weeknight dinner into something that feels like restaurant food. A juicy chicken breast, a layer of creamy mushroom filling and a crisp, golden exterior of puff pastry – and it all comes out of the air fryer in a fraction of the time the oven would take. It’s my go-to when I want to impress without standing in the kitchen all evening.

The secret lies in two things: that the filling is chilled and almost dry before it’s wrapped, and that the temperature is kept low enough for the pastry to rise and turn crisp before the chicken dries out. Both are easy to manage in an air fryer, and in this guide I’ll walk you through exactly how.

Why I love Small Chicken Wellington in the air fryer
Chicken Wellington hits a sweet spot where it looks festive but is really everyday food. You don’t have to fry in several batches or fire up a whole oven for two portions. The circulating hot air in the air fryer hits the puff pastry from all sides, so it rises evenly and turns crisp all the way through – without the soft underside you often end up with on a baking tray.
At the same time the chicken breast stays tender because the pastry acts as a shield. It holds in the juices and lets the meat steam gently on the inside while the crust takes on colour. The result is a dish with three distinct textures: crisp, creamy and juicy.
The difference between air fryer and oven
In a regular oven, Chicken Wellington usually takes 30-35 minutes, and the pastry easily turns pale on top if it doesn’t get extra grill heat at the end. In the air fryer the powerful air circulation is closer to the food, so the same result is achieved in 18-22 minutes with a more even golden surface. You save both time and electricity – and avoid firing up the big oven for a single dish.
My kitchen test of the Small Chicken Wellington
I tested Chicken Wellington in my Cosori Dual Blaze at 180 °C, and 20 minutes hit the perfect point: the puff pastry was deeply golden and flaky, and the core temperature of the chicken was 73 °C when I pushed the thermometer in through the pastry. At a higher temperature (200 °C) the pastry browned too quickly before the chicken was cooked through – which is why 180 °C is the key. I fried off the mushroom filling in the pan first, so all the liquid evaporated; a wet filling is the fastest route to a soggy bottom. On a Philips XXL with a larger basket you can easily make four portions at a time without them touching each other.
Brush the puff pastry with beaten egg twice – once before, and once after the first ten minutes. It gives a deep, glossy golden colour that you otherwise only see on pastries from a bakery.
Tips and tricks from the author: Morten Jensen
The typical mistakes and how to avoid them
The most frequent mistake is a warm or wet mushroom filling. If you wrap the filling while it’s still steaming, the moisture softens the pastry from the inside, and you get a chewy bottom instead of a crisp crust – always let the filling cool completely, and fry off the liquid in the pan first. The next mistake is too high a temperature: many turn it up to get colour quickly, but then the pastry is dark long before the chicken reaches 72 °C inside; stick to 180 °C and give it time. The third mistake is a leaky wrapping. If the seams aren’t pressed firmly together and turned downwards, the pastry bursts open and the juices run out – press the edges together with a fork and place the parcel seam-side down in the basket.
How to serve Chicken Wellington
Chicken Wellington is filling on its own, so the best side dishes are light and fresh. These suggestions work every time:
- A crisp green salad with a lemon and olive oil dressing
- Steamed haricots verts or asparagus
- A dollop of cold crème fraîche with fresh tarragon
- Oven-roasted baby potatoes or a light mash
- A glass of dry white wine or a light pinot noir
Storage and reheating
Leftovers keep for 2-3 days in an airtight container in the fridge. Always reheat in the air fryer at 160 °C for 6-8 minutes – the microwave makes the puff pastry soft and rubbery. You can also freeze the parcels raw: wrap them individually, freeze, and cook directly from frozen at 180 °C for 26-28 minutes.
With chilled filling, 180 °C and a little patience with the egg wash, you get a Chicken Wellington that’s crisp all the way around and juicy inside every time. It’s a dish that looks difficult but that the air fryer makes surprisingly easy.
FAQ
180 °C is the ideal temperature. It gives the puff pastry time to rise and turn crisp all the way through, while the chicken reaches a safe core temperature of 72 °C without the pastry burning.
Reckon on 18-22 minutes at 180 °C depending on the size of the chicken breast. The parcel is done when the puff pastry is deeply golden and the core temperature of the chicken is at least 72 °C.
Yes. Freeze the parcels raw and individually wrapped. Cook directly from frozen at 180 °C for 26-28 minutes, and always check that the core temperature reaches at least 72 °C before serving.

Ingredients
Chicken
- 4 pcs chicken breast (About 600 g in total)
- 1 tsp salt
- 0.5 tsp black pepper (Freshly ground)
- 1 tbsp olive oil (For browning)
Mushroom Sauce (Filling)
- 250 g mushrooms (Finely chopped)
- 1 pcs shallot (Finely chopped)
- 1 clove garlic (Finely chopped)
- 25 g butter
- 1 tbsp plain flour
- 1 dl cooking cream
- 1 tsp fresh thyme (Chopped)
- salt and pepper (To taste)
Wrapping
- 2 plader puff pastry (Fresh, about 270 g)
- 1 pcs egg (Beaten, for brushing)
How to make it
Preparation
- Melt 25 g butter in a pan over medium heat. Gently sauté 1 pcs shallot and 1 clove garlic until soft without taking on colour. Add 250 g mushrooms and fry until all the liquid has evaporated. Sprinkle over 1 tbsp plain flour, stir, and gradually add 1 dl cooking cream to make a thick sauce. Season with 1 tsp fresh thyme, salt and pepper, and let the mushroom sauce cool completely.
- Season 4 chicken breasts with 1 tsp salt and 0.5 tsp black pepper. Heat 1 tbsp olive oil in the pan and brown the chicken for 1-2 minutes on each side, so it takes on colour but is not cooked through. Let the chicken cool.
- Roll out 2 plader puff pastry and cut into 4 equal pieces. Spread a little cooled mushroom sauce on each piece of pastry, place a chicken breast on top, and wrap the pastry tightly around the chicken. Seal the seams well, and brush with 1 pcs egg.
Cooking in the Air Fryer
- Preheat the air fryer to 180 °C fan. Place a piece of baking paper in the basket.
- Place the wrapped chicken pieces in the air fryer seam-side down. Bake at 180 °C for 16-18 minutes, until the puff pastry is golden brown and crisp and the chicken reaches a core temperature of 75 °C. Turn carefully halfway through if the colour becomes uneven.
Serving
- Let the wrapped chicken rest for 5 minutes so the juices settle before serving.
Our notes for the recipe
Make sure the mushroom sauce is completely cold before you wrap it — warm sauce makes the puff pastry soft and stops it from turning crisp. Place the parcels seam-side down so they don’t open during baking. Variation:
Add a slice of serrano ham or a little grated Parmesan along with the mushroom sauce for extra richness. Fresh parsley or tarragon can replace the thyme. Serving:
Serve with a fresh green salad, oven-roasted root vegetables or boiled potatoes and perhaps a gravy made from extra mushroom sauce. Portion size:
If your air fryer is smaller, you can bake the wrapped chicken in two batches so they don’t touch each other.
