Instructions

Cooking process: Overhead shot of four assembled mini Beef Wellingtons resting seam-side down in an

Prep the beef: Pat the beef dry. Season all sides generously with salt and pepper.
Let sit at room temperature for 15 minutes while you prep the mushrooms.
Make the mushroom duxelles: Heat olive oil and butter in a skillet over medium heat. Add mushrooms, shallot, and a pinch of salt. Cook, stirring, until the mixture releases its moisture and becomes dry and concentrated, 8–10 minutes.
Add garlic and thyme; cook 1 minute more. Remove from heat and cool completely.
Sear the beef: Heat the same skillet over medium-high. Sear the beef for 45–60 seconds per side to brown, not cook through.
Transfer to a plate and brush all over with Dijon. Let cool. Cold components help keep the pastry crisp.
Prep pastry and prosciutto: Lightly flour your surface. Roll the puff pastry to smooth creases, then cut into 4 rectangles large enough to wrap each piece of beef.
If using prosciutto, lay a slice on each rectangle.
Assemble: Spread a tablespoon of mushroom duxelles over the prosciutto or directly on the pastry. Place a beef medallion in the center. Fold the pastry up and over the beef, sealing seams firmly.
Trim excess pastry if needed. Place seam-side down. Brush with egg wash.

Score lightly on top for vents.
Chill: Refrigerate the wrapped Wellingtons for 15–20 minutes. Chilling helps prevent blowouts and keeps the pastry flaky.
Preheat the air fryer: Set to 390°F (200°C) for 3–5 minutes. Lightly spray the basket or use a parchment liner with perforations.
Air fry: Arrange Wellingtons in a single layer with space between. Air fry at 390°F (200°C) for 10–14 minutes for medium-rare, depending on thickness and your air fryer model. Internal temp for medium-rare: 125–130°F (52–54°C) after resting.
Rest and serve: Let rest 5 minutes.
The carryover cooking will bring them to a perfect pink center. Serve hot with a simple pan sauce, peppercorn sauce, or a side of greens.

Storage Instructions

Uncooked, assembled: Wrap tightly and refrigerate up to 24 hours. For longer storage, freeze on a baking sheet until solid, then transfer to a freezer bag for up to 2 months.
Cooking from frozen: Air fry at 360°F (182°C) for 8 minutes, then increase to 390°F (200°C) for 10–12 minutes more.
Check internal temperature and adjust time as needed.
Cooked leftovers: Refrigerate in an airtight container for up to 2 days. Reheat in the air fryer at 330°F (165°C) for 5–7 minutes to re-crisp the pastry.

Final dish presentation: Restaurant-quality plate featuring one whole mini Beef Wellington alongside

Benefits of This Recipe

Restaurant quality at home: You get impressive presentation and rich flavor without specialized techniques.
Time-saving: Mini portions cook quickly, ideal for weeknights or last-minute entertaining.
Less waste: Individual Wellingtons mean everyone gets their own serving, with fewer leftovers.

Pitfalls to Watch Out For

Soggy pastry: Make sure the mushroom mixture is dry and fully cooled. Wrap tightly and chill before cooking.
Overcooked beef: Sear briefly and rely on the air fryer for final cooking.
Use an instant-read thermometer.
Pastry blowouts: Don’t overfill. Seal seams well and place seam-side down. A quick chill helps.
Crowding the basket: Leave space for airflow.
Cook in batches if needed for even browning.
Warm pastry: Work with cold pastry; if it softens, pop it back in the fridge for 5–10 minutes.

Variations You Can Try

Blue cheese twist: Add a thin smear of blue cheese under the mushroom layer for a bold, creamy note.
Bacon wrap: Swap prosciutto for lightly cooked bacon to add smoky flavor and extra protection against moisture.
Herb and pepper crust: Press cracked black pepper and chopped rosemary onto the beef before searing.
Truffle mushroom: Finish the duxelles with a few drops of truffle oil after cooling for a luxe touch.
Gluten-free approach: Use gluten-free puff pastry and confirm mustard and prosciutto are GF-friendly.
Mini appetizer bites: Use 2-ounce beef cubes and cut pastry smaller. Reduce air-fry time to 7–9 minutes.

FAQ

Can I use a different cut of beef?

Yes. Beef tenderloin is classic for tenderness, but you can use sirloin or filet mignon medallions.

Choose a lean, tender cut about 1.5 inches thick for best results.

Do I really need the prosciutto?

No, but it helps keep moisture from the mushrooms away from the pastry. If skipping it, make sure the duxelles is very dry and cooled, and consider brushing the pastry with a thin layer of Dijon as a barrier.

How do I know when they’re done?

Use an instant-read thermometer. Aim for 125–130°F for medium-rare after resting, 135°F for medium.

Check at the 10-minute mark and add time as needed.

Can I make these ahead?

Absolutely. Assemble and refrigerate up to 24 hours, or freeze for up to 2 months. Cook from chilled or frozen, adjusting time slightly.

What dipping sauces work well?

Peppercorn sauce, red wine reduction, horseradish cream, or a quick pan sauce with beef drippings, butter, and a splash of brandy are all great choices.

Why is my pastry pale?

Make sure you used egg wash and a hot air fryer.

If needed, add 1–2 extra minutes to brown, but avoid overcooking the beef—use a thermometer to monitor.

Can I skip the sear?

Searing builds flavor and color and helps render the exterior slightly, which improves the final texture. If you skip it, expect a milder flavor and add a minute or two to the air fry time.
