Beef Wellington is a project. Accept that before you start. It takes time, it takes attention, and every component needs to be completely cold before assembly or the pastry turns to mush. What it gives back is a dinner that almost never lands flat. Seared tenderloin, mushroom duxelles cooked until bone dry, Dijon mustard holding it all together, puff pastry bronzed in the oven. The temperature window matters: pull it at 125°F internal for medium-rare, tent it, wait. That rest is essential in the casual sense; it’s where the juices redistribute and the slice becomes clean.
How to Make Beef Wellington
The duxelles must be dry
Cook the mushrooms long past the point where they look done. Any moisture left in the duxelles will turn the pastry bottom soggy no matter how careful you are during assembly. They should look almost paste-like and cling to a spoon without weeping liquid.
Cold components, always
Sear the beef, then refrigerate until cold. Spread the duxelles, roll in the prosciutto, refrigerate again. Wrap in pastry only when everything is cold. Rushing any of these stages leads to a soggy bottom and uneven cooking. Build in the time. 
Reading the oven
A meat thermometer is essential here. Ovens vary, and the difference between 120°F and 140°F is the difference between a pink, perfect center and something you’ll apologize for. Start checking at 20 minutes and pull it early rather than late.

Description
Beef Wellington is the grand statement of British celebratory cooking — a center-cut beef tenderloin seared to a deep crust, wrapped in mushroom duxelles and puff pastry, and roasted until the pastry is golden and the beef inside is still rosy pink. It is a dish that demands planning and precision, but when the first slice reveals that seamless transition from crisp pastry to earthy mushrooms to perfectly medium-rare beef, every minute of effort is justified.
Ingredients
- 1 center-cut beef tenderloin (2 1/2 pounds), trimmed and tied
- 2 tablespoons vegetable oil
- Kosher salt and freshly ground black pepper
- 2 tablespoons Dijon mustard
- For the duxelles:
- 1 1/2 pounds cremini mushrooms, finely chopped
- 2 tablespoons unsalted butter
- 2 shallots, finely minced
- 3 cloves garlic, minced
- 2 tablespoons fresh thyme leaves
- 1/4 cup dry sherry
- 1/2 teaspoon kosher salt
- For assembly:
- 8 slices prosciutto
- 1 sheet all-butter puff pastry (about 14 ounces), thawed
- 1 large egg beaten with 1 tablespoon water (egg wash)
- Flaky sea salt
Instructions
- Season the beef generously with salt and pepper. Heat the vegetable oil in a large skillet over high heat until smoking. Sear the beef on all sides, including the ends, until a deep brown crust forms, about 2 minutes per side. Remove and let cool completely. Brush all over with Dijon mustard.
- For the duxelles: melt the butter in the same skillet over medium-high heat. Add the mushrooms and cook, stirring occasionally, for 10-12 minutes until all the moisture has evaporated and the mushrooms are dry and concentrated. Add the shallots, garlic, and thyme. Cook 2 minutes more. Add the sherry and cook until completely evaporated. Season with salt. Spread on a plate and cool completely.
- Lay a large sheet of plastic wrap on your work surface. Shingle the prosciutto slices in a rectangle large enough to wrap the beef. Spread the cooled duxelles in an even layer over the prosciutto.
- Place the seared, cooled beef at the bottom edge. Using the plastic wrap to help, roll the prosciutto and duxelles tightly around the beef, forming a compact log. Twist the ends of the plastic wrap tightly. Refrigerate for at least 30 minutes.
- Roll the puff pastry into a rectangle large enough to wrap the beef. Unwrap the beef log and place it on the pastry. Brush the edges with egg wash, then fold the pastry around the beef, sealing the seam on the bottom. Trim and seal the ends. Brush the entire surface with egg wash. Score the top with a sharp knife in a decorative pattern if desired. Refrigerate for 15 minutes.
- Preheat the oven to 425°F. Place the Wellington seam-side down on a parchment-lined sheet pan. Brush again with egg wash and sprinkle with flaky salt. Roast for 25-30 minutes until the pastry is deeply golden and a thermometer inserted into the center reads 120°F for medium-rare.
- Rest for 10 minutes before slicing with a sharp, serrated knife. The internal temperature will rise to about 130°F during resting.
Notes
- Every component must be completely cool before assembly, or the pastry will turn soggy from steam. Plan for cooling time at each stage.
- The duxelles must be cooked until absolutely dry — any residual moisture will create a soggy layer between the pastry and the beef.
- The prosciutto layer serves a dual purpose: it adds flavor and acts as a moisture barrier between the wet mushrooms and the pastry.

Frequently Asked Questions
What internal temperature should I aim for?
For medium-rare, pull the Wellington at 125 degrees and let it rest for ten minutes; carryover cooking will bring it to about 130 to 135 degrees. For medium, aim for 135 degrees before resting.
Can I make Beef Wellington ahead of time?
Yes. Assemble the full Wellington, wrap tightly in plastic, and refrigerate for up to 24 hours before baking. Add a few extra minutes to the baking time since it will be cold going into the oven.
Why is the mushroom duxelles so important?
It adds concentrated savory flavor and forms a barrier around the beef. Cooking out all the moisture is essential; if the duxelles is wet, it will steam inside the pastry and make the crust soggy instead of crisp.
