Ingredients
Method
Preparation
- Preheat oven to 400°F (200°C).
- Season the beef tenderloin generously with salt and pepper.
- Heat olive oil in an oven-safe skillet over high heat. Sear the tenderloin on all sides until nicely browned (about 2-3 minutes per side).
Prepare the Duxelles
- In the same skillet, melt the butter over medium heat.
- Add the shallots and cook until softened (about 3 minutes).
- Add the mushrooms and garlic, and cook until the mushrooms have released their moisture and are browned (about 8-10 minutes).
- If using, stir in the sherry and cook for another minute until slightly reduced.
- Season with salt and pepper. Set aside to cool.
Assemble the Wellington
- Spread the Dijon mustard evenly over the seared beef tenderloin.
- Spread the cooled duxelles evenly over the mustard.
- Carefully unroll the puff pastry on a lightly floured surface.
- Place the beef tenderloin in the center of the pastry.
- Fold the pastry over the beef, tucking in the edges to create a neat parcel.
- Crimp the edges to seal.
Bake the Wellington
- Brush the pastry with the beaten egg.
- Place the Wellington seam-side down on a baking sheet.
- Bake for 25-30 minutes, or until the pastry is golden brown and the internal temperature of the beef reaches 130-135°F (54-57°C) for medium-rare.
Rest and Serve
- Remove the Wellington from the oven and let it rest for 10-15 minutes before slicing and serving.
Notes
Don’t overcrowd the pan when searing the beef and ensure the duxelles cool completely before assembling. High-quality puff pastry contributes to a better result.
