Beef Wellington – Classic Method and Sous Vide

I often cook dinners for different occasions, and most of them never become blog posts. This time I was allowed to be a little more ambitious. It was a fortieth birthday, the menu was larger than I usually make, and the main course was Beef Wellington.

This dish takes some planning, but there is nothing mysterious about it. The important things are to cook the mushrooms completely dry, keep every component cold before wrapping, and use a meat thermometer. That gives you crisp pastry and pink beef instead of soggy pastry and overcooked fillet.

What is Beef Wellington?

A Wellington is a whole beef fillet wrapped with Dijon mustard, duxelles, cured ham and puff pastry. Duxelles is simply finely chopped mushrooms cooked until almost all their moisture has evaporated.

Traditional versions sometimes include foie gras or pâté. I think the dish is rich enough without it. If you want to go completely over the top, I will not stop you, but it is not necessary for a good result.

Beef Wellington for 5–6 people

Beef fillet

• 1 kg centre-cut beef fillet, preferably even and thick
• 1½ tsp salt
• Plenty of freshly ground black pepper
• 2 tbsp neutral oil for frying
• 2 tbsp Dijon mustard

Duxelles

• 500 g chestnut or button mushrooms
• 2 shallots
• 2 garlic cloves
• 30 g butter
• 1 tsp finely chopped thyme, or ½ tsp dried
• 100 ml dry sherry or port
• ½ tsp salt
• Black pepper

For wrapping

• 10–12 thin slices Parma or Serrano ham, about 150–200 g
• 500–600 g puff pastry
• A little plain flour for rolling
• 1 egg
• 1 tbsp water

Optional port sauce

• 100 ml port
• 200 ml good beef stock
• 100 ml double cream
• 20 g cold butter
• Salt and pepper

1. Make the duxelles

Clean the mushrooms and pulse them in a food processor until finely chopped. You can also chop them by hand. Finely chop the shallots and garlic.

Melt the butter in a wide frying pan. Cook the shallots over medium heat until soft without letting them colour much. Add the mushrooms, garlic, thyme, salt and pepper. Continue cooking, stirring regularly.

When the liquid from the mushrooms has evaporated, add the sherry or port. Keep cooking until the mixture is dark, concentrated and dry enough to hold together almost like a coarse pâté. This usually takes 20–30 minutes. Spread the duxelles on a tray and let it cool completely.

2. Prepare the beef

Trim the fillet and tie it with kitchen string if necessary to give it an even thickness. Season with salt and pepper.

Heat a pan until very hot, add the oil and sear the beef quickly on every side, including the ends. The aim is a browned crust, not to cook the fillet through. Remove it, take off the string and brush the whole piece with Dijon mustard while it is still warm. Cool completely.

If you want to use sous vide

Use a whole fillet that has not been injected or mechanically tenderised. Season and vacuum-seal it. Cook at 52°C for 2½–3½ hours, depending on thickness. Place the bag in ice water for 15–20 minutes, then refrigerate until the outside is cold. Remove it, dry it extremely well and sear it hard and fast on every side, including the ends. Brush with mustard and use the meat the same day.

Sous vide makes the core temperature easier to control, but it does not solve everything. The meat and duxelles must still be dry, and the pastry must be properly baked.

3. Wrap in ham and mushrooms

Lay a large sheet of cling film on the worktop. Arrange the ham slices in a slightly overlapping rectangle large enough to wrap around the fillet. Spread the cold duxelles evenly over the ham.

Place the fillet at the lower edge. Use the film to roll the ham and mushrooms tightly around the beef. Twist the ends to form an even cylinder. Refrigerate for at least 30 minutes; a few hours is fine.

4. Wrap in puff pastry

Roll the pastry to about 3 mm thick on a lightly floured surface. It should enclose the meat without several layers of overlap.

Remove the film and place the wrapped beef on the pastry. Brush the edges with egg beaten with water. Fold the pastry tightly around the meat, press the seam together and trim the excess. Place seam-side down.

Decorate with pastry scraps if you like, but do not cover the entire surface with another layer. Brush with egg and chill for 20–30 minutes. Brush again before baking and make a few small cuts in the top so steam can escape.

5. Bake the Wellington

Heat the oven to 200°C, conventional heat. Place the Wellington on a lined tray and bake in the centre.

Start checking after 25 minutes. Remove it when the pastry is deeply golden and the core is 48–50°C for pink beef. It will rise a few degrees while resting. For meat closer to medium, remove at 52–54°C.

A one-kilo Wellington often takes 30–40 minutes, but thickness and starting temperature matter more than the clock. Use a thermometer. If the pastry browns too quickly, cover loosely with foil.

Rest uncovered for 15 minutes before cutting into thick slices. Do not wrap it in foil; steam will soften the pastry.

6. Port sauce, if you want it

Reduce the port by half. Add the stock and reduce until concentrated. Add the cream and simmer to the right consistency. Remove from the heat and whisk in the cold butter. Season.

How to divide the work

The day before

• Make and chill the duxelles.
• Trim the beef.
• Make the sauce almost completely, but wait to add the cold butter.

On the day

• Sear the beef, brush with mustard and cool.
• Wrap in ham and duxelles.
• Wrap in puff pastry and chill.
• Bake shortly before serving.

With sous vide, start early the same day, chill the meat and assemble in the afternoon. Without sous vide it is still manageable in one day, but every component needs time to become cold between stages.

The most common mistakes

• Wet duxelles: Cook the mushrooms completely dry. This is the most important step against soggy pastry.
• Warm beef: It melts the butter in the pastry before it reaches the oven.
• Too much pastry: Thick seams remain doughy. Trim the excess.
• Baking by the clock: Let core temperature decide.
• Foil while resting: Steam softens the crust.

Beef Wellington is not everyday food, and that is the point. It is for occasions when you want to make a little more of the main course. Allow plenty of time, keep everything cold and dry, and let the thermometer decide when it is done.
