Ingredients
Equipment
Steps
- 1
Season beef cubes with salt and pepper. Sear quickly in a hot skillet, 30 seconds per side. Set aside.
- 2
In the same pan, cook mushrooms with butter until all moisture evaporates. Season with thyme, salt, and pepper. Cool slightly.
- 3
Cut puff pastry into squares. Brush with mustard. Place a spoonful of mushrooms and a beef cube on each. Wrap and seal edges.
- 4
Brush with egg wash. Sprinkle with flaky salt.
- 5
Air fry at 400°F for 12-14 minutes until pastry is deeply golden and puffed.
Tip: The duxelles must be cooked until completely dry or the pastry gets soggy. Searing the beef adds flavor but keeps the inside rare — it finishes cooking in the pastry. Freeze assembled bites 10 minutes before air frying for neater results.
Why Air Fry This?
- ⏱️Ready in 14 minutes vs ~25 in a conventional oven — no preheating needed.
- 🍖Circulating hot air renders fat and seals in juices for a crispier outside and tender inside.
- ⚡Uses significantly less energy than heating a full-size oven for a single batch.
