Ingredients
- 400g chestnut mushrooms
- 3 small brown onions
- 1 whole head garlic
- 8tbs olive oil
- Sea salt
- 150ml cream
- 100g crème fraîche
- 4tbs soy sauce
- Juice of one lemon
Directions
Prepare the oven: Preheat the oven to 140°C.
- Place one large sheet of tinfoil on an oven tray.
Prep the vegetables: Slice the mushrooms into quarters and place in the centre of the tinfoil.
- Peel the onions, remove the ends, and slice in half.
- Add the halved onions to the tinfoil beside the mushrooms, along with the whole head of garlic.
Season: Pull up each side of the tinfoil then drizzle the olive oil over the mushrooms, onions, and garlic.
- Season well with sea salt.
Create the parcel: Fold two opposite sides of the tinfoil to the middle so the edges meet.
- Fold one edge over the other, then fold up the remaining two sides to create a sealed parcel.
Slow roast: Place in the oven and cook at 140°C for two hours.
Extract garlic: Remove from the oven and open the tinfoil carefully.
- Using a serrated knife, carefully remove the base of the garlic bulb and squeeze out the roasted garlic pulp into a blender.
Blend: Add the mushrooms, onions, and all juices from the tinfoil to the blender.
- Add the cream, crème fraîche, soy sauce, and lemon juice and blend.
- Check the seasoning and adjust with sea salt.
Storage and serving: Spoon the sauce into a jar; it can be stored in the fridge for a few days.
- Reheat in a small pot when cooking your pasta, adding a splash of cream and a little pasta water if needed to loosen the sauce slightly.
