Instructions

Fry the Veg
1

a) Preheat your oven to 240°C/220°C fan/gas mark 9. Keep the puff pastry in the fridge until you need to use it.

b) Meanwhile, halve, peel and dice the onion. Peel and grate the garlic (or use a garlic press). Roughly chop the sliced mushrooms.

c) Heat a drizzle of oil in a large frying pan on medium-high heat.

d) Once hot, add the onion and mushrooms and stir-fry until softened, 5-6 mins. 

Prep the Filling
2

a) Once the veg has softened, stir in the garlic, half the dried rosemary and half the dried thyme. Cook, stirring, for 30 secs. Season with salt and pepper, then remove from the heat.

b) Pop the mushroom mixture into a bowl and put it into the fridge to allow to cool, 5-10 mins.

c) Break up the plant-based burgers into a large bowl and combine with the remaining dried rosemary and thyme. Roll the mixture into two log shapes,roughly 20cm long.

Serve Up a Festive Treat
3

a) Halve the pastry sheet and lay both halves on a large baking tray, keep it on its baking paper.

b) Once the mushroom filling has cooled, spoon it over each pastry half, leaving a 2cm border. Place a plant-based log each on top of the mushroom mixture.

c) Fold the pastry over the filling to enclose it, cut away some of the excess pastry, then gently press down the edges with the back of a fork to seal the 3 open sides. Poke 3 holes along the top with a sharp knife.

d) Place the Wellingtons on the middle shelf of your oven until golden, 20-25 mins, then rest for a few mins before transferring to a serving platter to finish.

Enjoy!
