There are few things more comforting on a chilly evening than a hearty pie to tuck into. Our delicious mushroom, kale and tarragon pie recipe is one you’re sure to return to, again and again.

Mushrooms are one of our go-to wellbeing staples. A valuable plant-based source of vitamin D, mushrooms, just like human skin, produce this vital vitamin when exposed to sunshine.

Placing your mushrooms on a windowsill to ripen for an hour will add significantly to their vitamin D content. Vitamin D is essential for maintaining bone density, reducing the risk of fracture, arthritis and osteoporosis. It also plays a key role in strengthening the immune system and has been associated with reduced risks of heart disease, cancer, diabetes and depression.

While you may prefer to make your own pastry for our mushroom pie recipe, we’ve used shop-bought here for ease. This pie is a quick and simple way to get a homecooked meal on the table that’s teeming with healthy vegetables. What’s more, this delicious recipe can feed four for just £8*, making it ideal for families.

Ingredients

  • 1 white onion, roughly chopped
  • 2 tbsp olive oil
  • 1 tbsp butter
  • 600g chestnut mushrooms, quartered lengthways
  • Salt and pepper, to season
  • 75g kale, woody ends removed and roughly chopped
  • 75ml white wine
  • 200g crème fraîche
  • 150g any smoked cheese, roughly chopped
  • 100ml whole milk
  • tinned anchovy (optional)
  • 10g tarragon, roughly chopped
  • 320g puff pastry (one sheet)
  • 1 egg, beaten

Method

  1. Preheat the oven to 180°C/350°F/gas mark 4. Place the onion and one tablespoon of olive oil to a large nonstick pan over a medium heat. Cook the onions, stirring often, for about 15 minutes until they are soft and translucent. Set the onions aside in a medium-sized pie dish.
  2. Add the butter and another tablespoon of olive oil to the pan and increase the heat to high. Once smoking, add the mushrooms and season well with salt and pepper. Fry for ten minutes, stirring regularly.
  3. Add the kale and stir fry for a further four minutes until wilted. Add all the veg to the pie dish with the onions.
  4. Into the same pan, add the wine, crème fraîche, smoked cheese, milk and anchovy, then stir over a low heat until smooth and combined. Add the tarragon and simmer for five minutes. Pour the sauce mixture over the veg in the pie dish and mix well.
  5. On a lightly floured surface, roll out your pastry, place on top of your pie and trim any excess (you can use this to decorate your pie). Brush the beaten egg over the pastry. Put in the oven and bake for 30-35 minutes until the pastry is golden brown.
