Ingredients

Servings4

12 oz beef tenderloin, cut into 1-inch cubes
1 sheet puff pastry (thawed if frozen), cut into 12 equal squares
8 oz cremini mushrooms, finely chopped
1 small shallot, minced
2 cloves garlic, minced
1 tbsp olive oil
1 tbsp unsalted butter
1 tsp fresh thyme leaves
1/2 tsp salt, divided
1/4 tsp black pepper, divided
1 egg, beaten (for egg wash)
Fresh parsley, finely chopped (optional, for garnish)

Instructions

In a medium skillet over medium heat, melt butter with olive oil. Add the minced shallot and garlic, sautéing until fragrant and translucent, about 2 minutes.
Add the finely chopped mushrooms and thyme leaves to the skillet. Cook, stirring occasionally, until the mushrooms release their moisture and it evaporates, and the mixture becomes thick and paste-like—about 8-10 minutes. Season with 1/4 tsp salt and 1/8 tsp pepper. Remove from heat and let cool completely.
Season beef tenderloin cubes evenly with the remaining salt and pepper.
Preheat your air fryer to 400°F (200°C) for 5 minutes.
Lay out the puff pastry squares on a clean surface. Spread about 1 tsp of the cooled mushroom duxelles onto each square, leaving the edges clear.
Place a cube of beef tenderloin in the center of each puff pastry square atop the mushroom duxelles.
Fold the puff pastry over the beef to enclose it completely, pinching and sealing the edges well. Gently shape each into a bite-sized parcel. If necessary, trim excess pastry to avoid too thick edges.
Brush each pastry-wrapped beef bite generously with beaten egg to achieve a golden, glossy finish during cooking.
Arrange the bites in a single layer inside the air fryer basket, making sure they do not touch. Cook for 10-12 minutes, or until the pastry is golden brown and crisp, and the beef reaches your desired doneness (medium-rare recommended).
Remove the bites carefully with a spatula; let rest for 3 minutes.
Optionally, garnish with finely chopped fresh parsley before serving. Enjoy these savory, crisp Beef Wellington bites as an elegant holiday appetizer or a special snack.

Recipe guidance

Crispiness Control

Pat the beef tenderloin dry, avoid crowding, and use only a light coat of oil or sauce before cooking. Add wet sauces near the end when you want the outside to stay crisp.

Storage

Store leftover Air Fryer Beef Wellington Bites with Mushroom Duxelles in an airtight container in the refrigerator for up to 3 days. Cool the food before sealing so excess steam does not soften the texture.
