Individual beef Wellingtons air-fry in about 20 minutes at 380 °F (193 °C) with no flipping, until the puff pastry is deep-golden and crisp and the beef inside reads 130 °F (54 °C) for medium-rare. A Wellington is a seared beef fillet coated in a dry mushroom duxelles, wrapped in puff pastry, and baked until the crust shatters and the rare beef rests pink inside — and the whole trick is keeping the pastry crisp while the beef stays rare. Make individual parcels rather than one large log: a single-portion Wellington fits the basket and cooks evenly, where a full log is too big and browns unevenly. Sear the fillet hard and cool it first so it doesn't overcook through the long pastry bake, cook the mushroom duxelles dry (and wrap the beef in prosciutto if you like) so no moisture sogs the base, then egg-wash the parcel and chill it firm so the pastry sets and crisps before the beef climbs past medium-rare. Unlike Sausage Rolls — seasoned sausage meat in puff pastry, cooked all the way through with no doneness window to hit — a Wellington has to thread the needle of crisp pastry over barely-set beef; and unlike a Cornish Pasty, a shortcrust hand-pie with a fully-cooked filling, the Wellington's flaky puff and rare fillet are the whole point. Use the same prime tenderloin cut as Filet Mignon for the centre, and rest the parcel five minutes before slicing so the juices settle. 4 ways to vary it: classic duxelles-and-prosciutto, with a smear of mustard or pâté, a mushroom-only vegetarian version, or mini cocktail Wellingtons.

How to tell it’s done

Done when the puff pastry is deep-golden, puffed, and crisp all over and the beef in the centre reads 130 °F (54 °C) for medium-rare. Don't flip it — the air fryer's circulating heat browns the parcel on every side, and turning it risks splitting the seam. The pastry colour and the thermometer are your two guides: if the crust is browning too fast before the beef is up to temperature, drop the heat 10–15 °F for the last few minutes. Rest the parcel 5 minutes before slicing so the juices settle and the centre finishes with carryover heat.

Internal temperature: 130 °F / 54 °C. Always verify with an instant-read thermometer.

Step-by-step method

1. 1

   Prep

   Bring ingredients close to room temperature. No oil spray — brush the pastry with beaten egg (egg wash) instead, which is what gives puff pastry its glossy, deep-golden bake. A second coat of egg wash just before cooking deepens the colour; oil would soften the crust rather than crisp it.

2. 2

   Season

   Season with Classic: a dry mushroom duxelles (finely chopped mushrooms, shallot, thyme, cooked dry) wrapped around the seared fillet, often over a layer of prosciutto., A thin smear of English mustard or pâté on the beef before wrapping adds the traditional savoury depth., Season the fillet hard with salt and pepper and sear it before wrapping — the pastry seals in whatever crust you build., Vegetarian version: a thick mushroom-and-spinach filling in place of the beef..

3. 3

   Load

   Arrange cook individual single-portion parcels, one per person, spaced apart in a single layer so the hot air browns the pastry all around; two to four fit a basket depending on size, and a full-size log won't cook evenly in an air fryer for best convection airflow.

4. 4

   Cook

   Set the air fryer to 380 °F (193 °C) and cook for 20 minutes total.

5. 5

   Check & rest

   Verify the internal temperature reaches 130 °F / 54 °C and rest 2–3 minutes before serving.

6. 6

   Store

   Best eaten fresh — the pastry is at its crispest straight from the basket. Refrigerate leftovers airtight up to 2 days; re-crisp at 350 °F (177 °C) for 4–6 minutes, knowing the beef will cook further past medium-rare on reheating. Assembled raw parcels can be chilled a few hours or frozen before baking — in fact chilling firm is part of the method.

Watch out for

• !Pre-sear the fillet and cool it completely before wrapping — a raw or warm centre overcooks past pink during the long pastry bake.
• !Cook the mushroom duxelles until it's dry; any moisture steams the pastry and leaves a soggy, raw base.
• !Chill the wrapped parcel firm before cooking so the pastry sets and crisps before the beef climbs past medium-rare — a warm parcel slumps and bakes greasy.
• !Make individual parcels, not one large log — a full Wellington is too big for a basket and cooks unevenly, leaving raw pastry seams or overcooked beef.
• !Use a thermometer; pastry colour alone won't tell you the beef is still rare inside, and there's no flip or visual cue for the centre.

FAQ about beef wellington in an air fryer

What temperature should I cook beef wellington at in an air fryer?

Cook beef wellington at 380 °F (193 °C). The convection air at this temperature cooks the centre evenly while still browning the surface.

How long does beef wellington take in an air fryer?

Beef wellington takes 20 minutes at 380 °F (193 °C) with no flipping needed. Cook in a single layer for the air to circulate.

Do you need to flip beef wellington in an air fryer?

No — beef wellington cooks evenly without flipping. The convection air reaches all sides simultaneously. Flipping is only needed for dense or thick foods where one side sits against the basket grate; this food does not benefit from it.

Do you need to preheat the air fryer for beef wellington?

Preheating is optional for beef wellington — most modern air fryers reach temperature in under 2 minutes and the food's total cook time already accounts for the ramp-up. If you do preheat, reduce the total time by 1–2 minutes and check earlier than usual.

What internal temperature is beef wellington safe to eat?

Beef wellington should reach an internal temperature of 130 °F (54 °C) measured at the thickest point with an instant-read thermometer. Visual checks alone are not a reliable substitute for protein — always confirm with a probe.
