There are some dishes that just make a statement, and Beef Wellington is one of them. A tender fillet steak coated in a rich mushroom duxelles, wrapped in prosciutto, and encased in golden, flaky puff pastry — it’s the kind of centrepiece that turns an ordinary dinner into something truly special. It looks impressive, tastes incredible, and yet it’s far more achievable at home than most people think.
This recipe uses a single thick-cut fillet steak, making it perfect for a special occasion meal for one or two — whether that’s a date night, a birthday, or simply treating yourself to something extraordinary. The optional lattice pastry cutter gives it that beautiful decorative finish that makes it look like it came straight from a professional kitchen. Serve it with roast potatoes and seasonal vegetables and prepare for compliments.
I’ll be honest — the first time I made Beef Wellington I expected it to be a real ordeal. But using a fillet steak rather than a large joint makes the whole thing so much more manageable. It cooks quickly, portions beautifully, and is just as impressive on the plate. I’ve made it for guests as well as quieter dinners for one or two, and it always goes down a treat. The lattice pastry cutter adds a gorgeous finishing touch that looks like it took real skill — when actually it takes about ten seconds. Easier than I ever thought it would be, and that’s coming from someone who was fully prepared for disaster.

Classic Beef Wellington made with Fillet Steak
Equipment
- Lattice Pastry Cutter
Ingredients
- 1 thick-cut fillet steak approx. 180–220g
- 2 slices prosciutto or Parma ham
- 100 g chestnut mushrooms very finely chopped
- 1 small shallot or ½ small onion finely chopped
- 1 garlic clove chopped
- 1 tsp fresh thyme leaves
- 1 tsp English mustard optional
- 1 small square of puff pastry ready-rolled or cut to fit
- 1 egg yolk beaten (for glazing)
- Salt & pepper
- Plain flour for dusting
- 1 tbsp of olive oil or butter
Instructions
- Preheat oven to 200°C (fan 180°C).
- Heat 1 tbsp oil or butter in a pan. Add the finely chopped shallot and garlic, cook for 1–2 mins. Add mushrooms, thyme, salt and pepper. Cook over medium heat until the mixture is dry and paste-like (10–15 mins). Let cool completely.
- Sear the fillet: Pat the fillet steak dry and season well. Heat a pan over high heat and sear the steak for 30 seconds per side. Remove and let cool.
- Optional: Brush the fillet with a little mustard.
- Lay out a sheet of cling film. Place the prosciutto slices slightly overlapping. Spread the mushroom mixture on top. Place the fillet in the centre and roll everything up into a tight log (use the corners of the cling film and gently pull over the steak to help roll) twist the ends of the cling film to secure. Chill in the fridge for 10–15 minutes.
- Roll out the puff pastry on a lightly floured surface.
- Remove the cling film from the steak, place the steak in the centre of pastry, Wrap the pastry around the steak, seal (pinch the pastry joins together. Place seam-side down on a lined baking tray.
- Brush the pastry with beaten egg yolk, then lightly score the top or use a lattice pastry cutter for a decorative finish. Bake for 20–25 minutes, or until pastry is golden and internal temp of beef is ~50–52°C for medium-rare. Then remove from the oven and let rest for 5–10 minutes before slicing
- To use a lattice pastry cutter, roll it firmly across a separate sheet of pastry, gently stretch it open to reveal the lattice pattern, then lay it over the top of the wellington before brushing with egg yolk
- Serve with vegetables and roast potatoes
Notes
Why You’ll Love This Recipe
- Restaurant quality at home — looks and tastes like a dish from a high-end steakhouse
- Premium but manageable — uses straightforward techniques that any home cook can follow
- Individual portion — ideal for a special dinner for one or two without a huge joint of meat
- Layers of flavour — earthy mushroom duxelles, savoury prosciutto, and buttery pastry all work together perfectly
- The lattice finish — optional but stunning, and it takes just seconds with the right cutter
- Worth every minute — the chill time does the hard work, so it’s not as hands-on as it looks
Tips For The Best Results
- Dry the duxelles completely — cook the mushroom mixture until every drop of moisture has evaporated and it’s paste-like; a wet duxelles will make the pastry soggy
- Sear the steak fast and hot — just 30 seconds per side, you’re sealing and colouring it, not cooking it through; let it cool completely before wrapping
- Chill the log before wrapping in pastry — the 10–15 minutes in the fridge firms everything up and helps the Wellington hold its shape
- Seal the pastry joins well — pinch firmly and place seam-side down on the tray so it stays secure during baking
- Use a meat thermometer — for medium-rare, aim for an internal temperature of 50–52°C; this takes the guesswork out entirely
- Always rest before slicing — 5–10 minutes out of the oven lets the juices redistribute so you get a clean, beautiful slice
Variations
- Try the lattice pastry cutter — roll it firmly across a separate sheet of pastry, gently stretch to reveal the pattern, and lay it over the top before egg washing for a stunning decorative finish
- Swap the prosciutto — Parma ham works just as well and is often easier to find
- Add mustard — brushing the seared fillet with English mustard before wrapping adds a subtle heat that pairs beautifully with the beef
- Use different mushrooms — a mix of chestnut and wild mushrooms makes the duxelles even more complex in flavour
- Make it for two — use two fillets side by side wrapped together in a slightly larger sheet of pastry
- Go dairy-free — use olive oil instead of butter for the duxelles and a dairy-free pastry
Frequently Asked Questions
Can I prepare Beef Wellington in advance?
Yes — and it’s actually recommended. You can make the Wellington up to the end of step 5 (the cling film log stage) and keep it in the fridge for several hours or even overnight before wrapping in pastry and baking. This makes it much more manageable for a dinner party, as the lengthy prep is done ahead and you just need to wrap, egg wash, and bake when you’re ready.
What internal temperature should Beef Wellington be for medium-rare?
Aim for an internal temperature of around 50–52°C for medium-rare. A digital meat thermometer inserted into the centre of the fillet is the most reliable way to check this, as oven temperatures and fillet thickness can vary. Remove it from the oven at this temperature and rest for 5–10 minutes — it will continue to rise slightly during resting.
What should I serve with Beef Wellington?
Roast potatoes and seasonal vegetables are the classic pairing and work beautifully. Tenderstem broccoli, green beans, or glazed carrots all complement it well. A rich red wine jus or peppercorn sauce on the side takes it to another level if you want to go all out.
