Ingredients & Their Purpose

For the Beef:

• 1 lb beef tenderloin (filet mignon) – The star of the show. Tender, juicy, and flavorful, this cut ensures melt-in-your-mouth texture.
• Salt and freshly ground black pepper – Enhances the beef’s natural flavor.
• 1 tbsp olive oil – Used to sear the beef and develop a rich crust before baking.

For the Mushroom Duxelles:

• 8 oz cremini or baby bella mushrooms, finely chopped – The base of the duxelles; adds deep umami flavor.
• 2 tbsp unsalted butter – Helps cook the mushrooms and enriches the duxelles.
• 1 shallot, finely minced – Adds a mild, aromatic sweetness to balance the mushrooms.
• 2 garlic cloves, minced – Provides a savory kick.
• 1 tsp fresh thyme leaves (or ½ tsp dried) – Adds herbal depth and fragrance.
• Salt and pepper, to taste – Balances and enhances the mushroom mixture.
• 1 tbsp dry white wine or sherry (optional) – Deglazes the pan and adds complexity.

Assembly:

• 1 sheet of puff pastry, thawed – Encases the beef and duxelles in a golden, flaky crust.
• 6 slider-sized brioche buns or puff pastry rounds – Acts as a base or cap for presentation.
• 6 slices of prosciutto or Parma ham – Adds a salty, savory barrier to keep the puff pastry crisp.
• 1 egg + 1 tbsp water (egg wash) – Helps the pastry achieve a golden finish.

Step-by-Step Instructions

1. Prepare the Beef

1. Trim any excess fat or silver skin from the beef tenderloin.
2. Cut into 6 slider-sized medallions, about 1½ inches thick.
3. Season both sides generously with salt and pepper.
4. Heat olive oil in a skillet over high heat.
5. Sear each medallion for 1 minute per side, until browned but still rare inside.
6. Remove from heat and let rest on a plate.

Pro Tip: Searing the beef locks in juices and creates a flavorful crust. Don’t overcook—it will finish in the oven.

2. Make the Mushroom Duxelles

1. In the same skillet, melt butter over medium heat.
2. Add shallots and garlic, cooking until soft and fragrant (about 2 minutes).
3. Stir in finely chopped mushrooms and thyme.
4. Sauté until all moisture has evaporated and mushrooms form a thick paste (10–12 minutes).
5. Deglaze with wine or sherry if using. Cook until absorbed.
6. Season with salt and pepper to taste. Let cool completely.

Pro Tip: The drier the duxelles, the better. Moisture will make your pastry soggy.

3. Assemble the Sliders

1. Preheat oven to 400°F (200°C).
2. Roll out the puff pastry slightly and cut into 6 squares large enough to wrap each slider.
3. Lay a piece of prosciutto on each square, followed by a spoonful of the duxelles.
4. Place a beef medallion on top, then wrap the pastry tightly around each one, sealing the edges underneath.
5. Place seam-side down on a parchment-lined baking sheet.
6. Brush the tops with egg wash.

Optional: Use puff pastry rounds instead of full wraps, topping each slider with a pastry “cap” for a more open-faced presentation.

4. Bake

1. Bake for 15–18 minutes, or until pastry is puffed and golden brown.
2. Let cool slightly before serving.

Serving Suggestions

• Serve these sliders warm with a side of horseradish cream, Dijon mustard aioli, or red wine reduction for dipping.
• Pair with garlic mashed potatoes, roasted asparagus, or a simple arugula salad dressed with lemon and olive oil for a complete meal.
• For a party platter, garnish with microgreens or fresh thyme sprigs for a gourmet presentation.

Pro Tips for Perfect Beef Wellington Sliders

• Chill your components: Cold beef and duxelles make wrapping easier and help keep the pastry crisp.
• Use a meat thermometer: Aim for an internal temp of 125–130°F (52–54°C) for medium-rare.
• Avoid overfilling: Too much duxelles or meat can cause the pastry to burst.
• Preheat your baking sheet: This helps the bottom of the sliders crisp up beautifully.
