• 2 Tbsp Fresh Parsley (chopped flat‑leaf)
• 0.25 cup Sour Cream (for spreading on bread)
• 2 Tbsp Dijon Mustard (for cheese melt layer)
• 8 slices Sliced Bread (standard white or rustic)
• 8 oz Young Gouda Cheese (thinly sliced)

Instructions

1. Slice Beef

   Using a chef's knife, slice the beef tenderloin into thin escalopes about 1/4‑inch thick.

   Time: PT5M

2. Flatten Beef

   Place each slice between two sheets of plastic wrap and gently pound with a meat tenderizer until uniformly thin.

   Time: PT5M

3. Prep Duxelles Ingredients

   Finely chop cremini mushrooms, yellow onion, and garlic. Set aside in a wooden bowl.

   Time: PT5M

4. Sweat Onion

   Melt butter in a sauté pan over medium heat. Add the chopped onion and cook, stirring, until translucent, about 3 minutes.

   Time: PT3M

   Temperature: Medium heat

5. Cook Mushrooms

   Add the chopped mushrooms to the pan with the onion. Stir‑fry until the mixture releases moisture and becomes fragrant, about 5 minutes.

   Time: PT5M

   Temperature: Medium heat

6. Season Duxelles

   Season the mushroom‑onion mixture with kosher salt, black pepper, and barberries. Fold in chopped parsley and remove from heat.

   Time: PT2M

7. Prepare Cheese Bread

   Spread sour cream on one side of each bread slice, then a thin layer of Dijon mustard on top. Layer sliced young Gouda over the mustard side.

   Time: PT5M

8. Toast Sandwiches

   Heat a griddle or skillet with a pat of butter over medium‑high heat. Place the assembled sandwiches butter‑side down, toast until golden, then flip once to brown the other side, about 2‑3 minutes per side.

   Time: PT5M

   Temperature: Medium‑high heat

9. Assemble Beef Roll

   Spread a generous layer of mushroom duxelles over each flattened beef slice. Place a toasted cheese‑bread sandwich on top and roll tightly, sealing the edges.

   Time: PT5M

10. Prepare Pastry Dough

    Divide the yeast pastry dough into 4 equal portions. Lightly dust a work surface with flour and roll each portion into a 12‑inch circle, keeping it thin but sturdy.

    Time: PT5M

11. Egg Wash and Wrap

    Brush the perimeter of each dough circle with beaten egg. Place a beef roll onto the dough, then fold the edges over, sealing tightly. Brush the top with more egg wash for sheen.

    Time: PT3M

12. Score Lattice Top

    Using a sharp knife, cut a lattice pattern across the top of each wrapped Wellington, leaving about 1/4‑inch between cuts for venting. Brush the lattice with egg wash and sprinkle sesame seeds over the top.

    Time: PT3M

13. Bake in Wood‑Fired Oven

    Transfer the prepared Wellingtons onto a floured tray. Load into a pre‑heated wood‑fired oven (about 400°F) and bake until the pastry is deep golden and the internal beef reaches 130‑135°F, roughly 35 minutes.

    Time: PT35M

    Temperature: 400°F

14. Rest and Slice

    Remove the Wellingtons with a peel, let rest on a cutting board for 5 minutes, then slice to reveal the layered duxelles and cheese‑bread filling.

    Time: PT5M
