Ingredients

• 1 lb (450 g) beef tenderloin – trimmed and cut into 12‑inch strips
• 12 slices prosciutto – thin, high‑quality
• 2 cups (200 g) mixed mushrooms – finely chopped (cremini, shiitake, porcini)
• 2 tbsp unsalted butter
• 1 small shallot, minced
• 2 cloves garlic, minced
• 1 tbsp fresh thyme leaves
• 1 tbsp Dijon mustard
• 1 package (≈ 17 oz) frozen puff pastry – thawed
• 1 egg, beaten – for egg wash
• Salt & freshly ground black pepper – to taste
• Olive oil – for searing

Step‑by‑Step Instructions

1. Prepare the beef: Pat the tenderloin strips dry with paper towels. Season generously with salt and pepper on all sides.
2. Sear the meat: Heat 2 tbsp olive oil in a heavy skillet over high heat. Sear each strip for 1‑2 minutes per side until a deep brown crust forms. Transfer to a plate and let cool for 5 minutes.
3. Make the mushroom duxelles: In the same skillet, melt butter over medium heat. Add minced shallot, garlic, and thyme; sauté until fragrant (≈ 1 minute). Add the chopped mushrooms, stirring constantly, until the mixture releases its moisture and then dries out (≈ 6‑8 minutes). Season with salt and pepper, then set aside to cool.
4. Brush with mustard: Lightly coat each seared beef strip with Dijon mustard. This adds a tangy layer that balances the richness of the meat and pastry.
5. Wrap with prosciutto: Lay out a slice of prosciutto on a clean surface. Place a beef strip on top, then spoon a thin line of mushroom duxelles along its length. Roll the prosciutto tightly around the beef, sealing the duxelles inside. The prosciutto acts as a moisture barrier, keeping the puff pastry crisp.
6. Prepare the puff pastry: On a lightly floured countertop, roll the thawed puff pastry into a 12‑inch square. Cut the square into 12 equal rectangles (≈ 3 × 4 inches each). Brush the edges of each rectangle with the beaten egg.
7. Assemble the mini Wellingtons: Place a prosciutto‑wrapped beef strip at the short end of each pastry rectangle. Roll tightly, sealing the edge with more egg wash. Turn the roll seam‑side down on a parchment‑lined baking sheet.
8. Egg wash & bake: Brush the tops of all mini Wellingtons with the remaining beaten egg for a golden sheen. Sprinkle lightly with flaky sea salt if desired. Preheat the oven to 400°F (200°C) and bake for 18‑22 minutes, or until the pastry is puffed and deep golden.
9. Rest before serving: Allow the bites to rest for 3‑5 minutes after removal from the oven. This helps the juices redistribute and prevents the pastry from becoming soggy.
10. Plate and garnish: Arrange the mini Wellingtons on a serving platter. Drizzle with a reduced red‑wine demi‑glace or a simple balsamic reduction, and garnish with micro‑greens or a sprinkle of fresh thyme.
11. Enjoy! Serve warm as an elegant appetizer, a main‑course component, or a luxurious party bite that will leave guests asking for the recipe.

Pro Tips & Tricks

• Chill the assembly: After wrapping the beef in prosciutto and before adding pastry, refrigerate the bundles for 10‑15 minutes. This firms the fat, making the pastry roll easier and helping the pastry stay flaky.
• Use a meat thermometer: Aim for an internal temperature of 130°F (54°C) for medium‑rare. The meat will continue to cook slightly while the pastry bakes.
• Don’t over‑crowd the pan: When searing, work in batches to maintain a high temperature. Overcrowding steams the meat and prevents a proper crust.
• Egg wash alternatives: For a richer color, mix a tablespoon of heavy cream with the egg. For a vegan version, use plant‑based milk with a touch of maple syrup.
• Make ahead: Assemble the mini Wellingtons up to the egg‑wash step, cover tightly, and freeze. Bake from frozen, adding 4‑5 minutes to the baking time.

Variations & Substitutions

The beauty of this recipe lies in its adaptability. Below are several creative twists to suit different tastes, dietary needs, and seasonal ingredients.

• Protein swaps: Replace beef tenderloin with pork tenderloin, lamb loin, or even a thick-cut salmon fillet for a surf‑and‑turf version.
• Mushroom medley: Incorporate dried porcini rehydrated in warm water for an intensified umami flavor.
• Truffle upgrade: Add a drizzle of white truffle oil to the mushroom duxelles before spreading.
• Gluten‑free pastry: Use a certified gluten‑free puff pastry; the texture remains delightfully flaky.
• Herb‑infused butter: Mix softened butter with rosemary, sage, and a pinch of smoked paprika; brush onto the pastry for an aromatic crust.
• Cheese element: Place a thin slice of Gruyère or aged cheddar on top of the mushroom duxelles before rolling for a melty surprise.

Storage Tips

Proper storage ensures your mini Beef Wellingtons stay fresh and retain their texture.

• Refrigeration: Store cooked bites in an airtight container in the fridge for up to 3 days. Reheat gently in a 350°F (175°C) oven for 8‑10 minutes to restore crispness.
• Freezing (pre‑bake): After assembling and brushing with egg wash, wrap each bite individually in plastic wrap, place in a freezer‑safe bag, and freeze for up to 2 months. Bake from frozen, adding a few extra minutes.
• Freezing (post‑bake): Cool completely, then freeze on a parchment sheet before transferring to a bag. Reheat directly from frozen in a preheated oven (375°F/190°C) for 12‑15 minutes.
