Beetroot Wellington with Chestnut Mushrooms, Lentils & Butternut Squash

Let’s give the classic beef wellington a ‘vegetal’ twist this year with our delicious beetroot and chestnut filling!

The traditional beef wellington is a type of beef joint pasty, made out of fillet steak, coated with pate and duxelles and then wrapped in puff pastry before being baked. Many historians believed the dish is named after Arthur Wellesley, who was the 1st Duke of Wellington.

Beetroot is the main component for our wellington, giving it a deliciously sweet and earthy flavour. We pair the beetroot with a bundle of chestnut mushrooms, lentils and butternut squash to give a gloriously nutty undertone to the dish. Once combined and wrapped together with a beautiful crisp pastry, your wellington will be the perfect centrepiece for Christmas.

If you want to take out the beetroot component, we offer a wonderful Butternut and Mushroom Wellington, which both equally looks impressive in colour and flavour! We recommend serving either wellingtons with our mouthwateringly good hasselback potatoes and lemon & honey glazed carrots.

1. Preheat oven to 180C / 356F / Gas Mark 4
2. Begin with the butternut squash. Place the diced squash onto a baking tray and drizzle with some oil, Maldon salt and cracked black pepper. Place into the oven and roast for 20 minutes until soft and cooked through.
3. Meanwhile, in a large frying pan heat 1 tbsp oil. Once the oil is hot, add the diced onion and fry gently for 5 minutes until softened. To the softened onions, add the crushed garlic and cook for a further 2 minutes. Next add the chopped chestnut mushrooms and continue to cook these for 5 – 8 minutes until the mushrooms have softened and beginning to caramelize.
4. Once the mushrooms are cooked, add the chopped sage and thyme leaves, followed by the cooked puy lentils and double cream. Allow this to fry and cook for 3 minutes, mixing well so everything is well combined. Remove from the heat and add the crumbled cooked chestnuts, Maldon Salt, cracked black pepper and the cooked butternut squash. Set aside and allow to cool.
5. Once the mixture has cooled, you are ready to assemble.
6. On a lightly floured surface roll out the puff pastry block until it is a roughly 30 x 40cm rectangle and 1cm thick. At this stage you want to carefully lift the rolled pastry onto a baking sheet lined with parchment paper. Next spoon on the cooled filling and spread out evenly, leaving a 1-inch boarder along the top and 1cm board round all the rest of the edges. Next take the cooked beetroot and make sure they are dry of any excess liquid. Choose beetroot that are similar in size and place them in a row down the middle.
7. Take one of the long sides and lift it up and over the beetroot to enclose them. Pinch the pastry together at the seams and rest the whole wellington seam side down. Pinch the pastry at either end of the wellington also, and trim off any excess.
8. Use the excess pastry to create long strips and decorate the top of the wellington with a lattice pattern (optional). And brush the entire thing with the beaten egg.
9. Place the wellington into the fridge for a minimum of 30 minutes (but the longer, the better) to cool.
10. When ready to bake, take your chilled wellington from the fridge and place into the preheated oven. Bake for 40 – 45 minutes until the pastry is golden and crisp all over.
11. Remove from the oven and allow to rest for 10 minutes before slicing and serving.

How to avoid your wellington becoming soggy?

The pastry base of your wellington may become soggy from the juices of the beetroots and mushrooms dripping down to the base when cooking.

To avoid this from happening, make sure that the beetroots and chestnut mushrooms are cooked until all of the liquid has evaporated. You can do this by chopping the vegetables finely and fry until dry. Equally, you can blot the veg with kitchen paper to ensure any further water is taken out.

What sauce goes well with a wellington?

A red wine sauce goes beautifully well with a wellington! You should add a handful of minced shallots to a red wine, slowly cooking on low heat until it is reduced by two thirds. Once reduced to a desired consistency, you can strain and discard of the shallots, leaving a beautiful red wine sauce to be served.
