Ingredients

Beef Wellington Ingredients:

750 g beef fillet trimmed
500 g chestnut mushrooms
200 g spinach
1 sheet puff pastry ready-made approximately 320–375g
1 tbsp Dijon mustard
2 cloves garlic finely chopped
1 small onion finely chopped
1 teaspoon fresh thyme leaves
1 tbsp unsalted butter
1 large egg beaten
salt to taste
black pepper to taste

Cooking the Beef Ingredients:

Instructions

Remove the beef fillet from the refrigerator and allow it to sit at room temperature for around 20–30 minutes.
Pat the beef dry with kitchen paper. Season it generously with salt and black pepper.
salt, freshly ground black pepper
Heat a large frying pan over a high heat. Add the olive oil and place the beef into the hot pan.
750 g beef fillet, 1 tbsp olive oil
Sear the beef for 1–2 minutes on each side. Also brown the ends carefully. The aim is to create a good crust rather than cook the beef through.
Remove the beef from the pan and place it on a plate. While it is still warm, brush the outside with Dijon mustard.
1 tbsp Dijon mustard
Leave the beef to cool completely before assembling the Wellington.
Clean the mushrooms and chop them very finely. A food processor can make this stage quicker, but avoid turning them into a smooth paste.
500 g chestnut mushrooms
Melt the butter in a large frying pan. Add the chopped onion and cook gently for 3–4 minutes.
1 tbsp unsalted butter, 1 small onion
Add the garlic and thyme, then cook for another minute.
2 cloves garlic, 1 teaspoon fresh thyme leaves
Add the mushrooms and increase the heat slightly. Cook until the mushrooms release their moisture.
Continue cooking until the mixture becomes quite dry. This can take around 10–15 minutes.
Season with salt and black pepper. Remove from the heat and allow the mushroom mixture to cool completely.
salt, black pepper
The mushrooms must be fairly dry. Excess moisture can make the pastry soggy.
Place the spinach into a large frying pan over a medium heat. You can add a small splash of water if needed.
Cook for 2–3 minutes until the spinach has wilted.
Transfer it to a sieve or colander. Allow it to cool enough to handle.
Squeeze the spinach firmly to remove as much liquid as possible. This step is important because wet spinach can soften the pastry.
200 g spinach
Roughly chop the drained spinach and set it aside.
Place a large sheet of cling film on the work surface.
Spread the cooled mushroom mixture into a rectangle that is large enough to wrap around the beef.
Spread the spinach evenly over the mushroom layer.
Place the cooled beef fillet in the centre.
Use the cling film to help bring the mushroom and spinach mixture around the beef. Press gently so everything forms a reasonably tight covering.
Twist the ends of the cling film and place the wrapped beef in the refrigerator for around 15–20 minutes.
Preheat the oven to 200°C, 180°C fan, or Gas Mark 6.
Unroll the puff pastry onto a lightly floured surface.
1 sheet puff pastry
Remove the beef from the cling film and place it in the centre of the pastry.
Fold the pastry around the beef. Trim away any large excess pieces, but leave enough pastry to seal the Wellington properly.
Press the edges together firmly. Place the Wellington seam-side down on a baking tray lined with baking parchment.
Brush the entire pastry surface with beaten egg.
1 large egg
If you like, use the back of a knife to make shallow decorative lines across the pastry. Take care not to cut through the pastry.
Make two or three tiny cuts in the top. These allow steam to escape during cooking.
Place the Beef Wellington into the preheated oven.
Bake for approximately 35–45 minutes, depending on the size of the beef and your preferred level of doneness.
For the best results, use a meat thermometer. Aim for approximately:
Rare: 50–52°C
Medium-rare: 54–57°C
Medium: 58–62°C
The internal temperature will continue to rise slightly while the beef rests.
The pastry should be beautifully puffed and golden brown when ready.
Remove the Wellington from the oven and leave it to rest for 10–15 minutes.
Use a sharp serrated or carving knife to cut it into thick slices.
Serve immediately with your favourite vegetables and a rich gravy or red wine sauce.

Notes

Tips for the Perfect Beef Wellington:

Keep everything cool before wrapping. Hot beef or mushroom mixture can soften the pastry and make it harder to handle.

Do not skip drying the spinach. Removing excess moisture helps keep the pastry crisp.

Cook the mushrooms thoroughly. They should lose most of their natural moisture before being added to the Wellington.

Do not overcook the beef during searing. The oven will finish cooking the centre.

Seal the pastry well. Any gaps can allow juices and steam to escape during baking.

Rest before slicing. This helps the beef retain its juices and makes the layers easier to cut cleanly.

Serving Suggestions:

Easy Beef Wellington works beautifully with traditional accompaniments. Try it with roast potatoes, creamy mashed potatoes, honey-roasted carrots or buttered green beans.

For something lighter, serve it with tender asparagus, steamed broccoli or a crisp green salad.

A rich red wine gravy makes an excellent sauce, while a creamy peppercorn sauce also works particularly well with the beef.

For a special dinner, I would serve generous slices with roasted vegetables and a spoonful of rich gravy. The golden pastry, dark mushroom layer, vibrant spinach and tender beef make an impressive presentation on the plate.
