Ingredients
- 1 tablespoon extra-virgin olive oil
- 2 small yellow onions, finely chopped
- 1 medium leek, white and light green parts only, thinly sliced
- 1 tablespoon butter
- 300 g cremini mushrooms, quartered or thick slices
- 2 medium carrots, peeled and diced
- 2 garlic cloves, minced
- 100 ml dry white wine
- 1 tablespoon arrowroot powder (or other starch or flour)
- 1/2 tablespoon grainy Dijon mustard
- 2 tablespoons crème fraîche
- 1 teaspoon Worcestershire-Sauce (z.B. Sanchon)
- 250 ml vegetable broth
- 1 small head of broccoli, cut into bite-sized florets
- 80 g frozen peas (about 1/2 cup)
- 1 x 400 g can organic white beans (cannellini oder butter beans), rinsed and drained
- 4-5 sprigs of fresh thyme, leaves picked
- 1 x 280 g roll puff pastry (24 x 40cm)
- 1/2 teaspoon coarse sea salt or salt flakes, plus more to taste
- Freshly ground black pepper, to taste
- 1 egg, lightly beaten (for the egg wash)
Instructions
- In a large, deep skillet, heat the olive oil over medium heat.
- Add the onion and leek and season with a pinch of salt. Cook until the onion is translucent and leek is soft, 10-15 minutes.
- Add the butter to the pan, increase the heat to medium-high and add the mushrooms. Cook for one minute, then add the diced carrots. Cook for 2 minutes, stirring occasionally, then add the garlic. Cook for 1 more minute.
- Add the white wine. Stir well and then once the wine has reduced return the heat to medium.
- Stir in the starch, Dijon mustard, crème fraîche and Worcestershire sauce until well combined. Then slowly add the broth; stirring the pan constantly. Add the thyme leaves and season with salt and pepper, to taste.
- Simmer for a 2-3 minutes and then stir in the white beans, broccoli and peas.Note: If you prefer a thicker sauce, then sprinkle an additional 1 teaspoon of arrowroot powder (or other starch) and stir well to combine.
- Meanwhile, preheat the oven to 400°F / 200°C (180°C fan-assisted).
- Transfer the filling to a casserole (I use a 32 x 22 cm / 2litre form). Alternatively, you can also use a large pie dish.
- Cover the mixture with the puff pastry, tucking in or crimping the overlapping edges. Cut a few vents into the surface and brush with the egg wash.
- Transfer to the preheated oven and bake for 20-30 minutes, until the pastry is golden brown and juices are bubbling.
- Remove from the oven and let cool slightly before serving. Enjoy!
