Ingredients

• 300 g (≈ 10 oz) beef tenderloin, cut into 1‑inch cubes
• 1 sheet puff pastry, thawed and cut into 4‑cm squares
• 200 g (≈ 7 oz) cremini mushrooms, finely chopped
• 1 shallot, minced
• 2 cloves garlic, minced
• 2 tbsp unsalted butter
• 1 tbsp olive oil
• 1 tbsp Dijon mustard
• 1 tsp fresh thyme leaves (or ½ tsp dried)
• Salt & freshly ground black pepper, to taste
• 1 egg, lightly beaten (egg wash)
• Fresh chives for garnish (optional)

Step‑by‑Step Instructions

1. Preheat the oven to 220 °C (425 °F). Line a baking sheet with parchment paper.
2. Prepare the duxelles: Heat butter and olive oil in a large skillet over medium heat. Add the minced shallot and garlic; sauté until fragrant, about 1 minute.
3. Add mushrooms and a pinch of salt. Cook, stirring frequently, until the mixture releases its moisture and becomes a thick, paste‑like consistency (≈ 6‑8 minutes). Stir in thyme, season with pepper, and set aside to cool.
4. Season the beef: Pat the beef cubes dry with paper towels. Toss with a little salt, pepper, and Dijon mustard in a bowl.
5. Sear the beef: In the same skillet (add a splash more oil if needed), sear the beef cubes on high heat for 1‑2 minutes per side until browned but still rare inside. Transfer to a plate; they will finish cooking in the oven.
6. Assemble the bites: On a lightly floured surface, roll out the puff pastry sheet to about 3 mm thickness. Cut into 4‑cm squares. Place a spoonful of cooled duxelles in the center of each square, then top with a seared beef cube.
7. Seal and brush: Fold the pastry corners over the beef to create a neat parcel, pressing gently to seal. Brush each parcel with the beaten egg wash for a golden finish.
8. Bake: Arrange the parcels on the prepared baking sheet, leaving space between them. Bake for 12‑15 minutes, or until the pastry is puffed and deep golden brown.
9. Rest and garnish: Let the bites rest for 2 minutes. If desired, drizzle with a thin line of extra Dijon mustard and sprinkle chopped chives for color.
10. Serve: Transfer to a serving platter and enjoy while still warm. Pair with a crisp white wine or a classic cocktail for the ultimate party experience.

Pro Tips & Tricks

• Dry the mushrooms thoroughly. Excess moisture will make the pastry soggy. After chopping, pat them with a paper towel before cooking.
• Use a kitchen torch. For an extra glossy finish, give the baked parcels a quick torch after they come out of the oven.
• Chill the assembled parcels. A 5‑minute chill in the refrigerator before baking helps the pastry hold its shape and prevents spreading.
• Don’t overcrowd the pan. Air circulation is key for an even puff; bake in batches if necessary.
• Use a meat thermometer. Aim for an internal temperature of 55 °C (130 °F) for medium‑rare; the final bake will bring it to perfection.

Variations & Substitutions

The beauty of this bite lies in its adaptability. Feel free to experiment with the following swaps to match dietary preferences or seasonal produce:

• Protein: Substitute beef with pork tenderloin, chicken breast, or even a firm tofu cube for a vegetarian twist.
• Mushroom mix: Combine cremini with shiitake or porcini for deeper umami.
• Herb profile: Replace thyme with rosemary or sage for a different aromatic note.
• Cheese boost: Add a thin slice of blue cheese or Gruyère on top of the duxelles before sealing.
• Gluten‑free: Use gluten‑free puff pastry and ensure all other ingredients are certified gluten‑free.

Storage Tips

If you need to prep ahead, these bites store beautifully. After baking, let them cool completely, then arrange in a single layer on a baking sheet and freeze for up to 2 weeks. Transfer to an airtight container or zip‑lock bag for longer storage. To reheat, bake directly from frozen at 200 °C (390 °F) for 8‑10 minutes, or until the pastry regains its crispness. For refrigeration, store in an airtight container for up to 2 days; re‑heat in a pre‑heated oven (180 °C) for 5‑7 minutes.
