Method
- This is for a small slow cooker (1.5 to 3.5 litres). In a bigger one, double everything and freeze half. Drain and rinse the cannellini beans. Trim the leeks, slice them into 1 cm rounds and rinse well in a colander to remove any grit. Dice the carrot into 1 cm pieces, crush the garlic and chop the parsley leaves.
- Put the beans, leeks, carrot and garlic in the slow cooker. Stir the Dijon mustard, dried thyme and olive oil together with 200 ml of water, crumble in the stock cube, and pour it over the vegetables.
- Put the lid on and leave it on. Cook on low for 6 to 7 hours or on high for 3 to 4 hours, until the leeks are silky and the carrot is tender.
- Just before serving, stir in the oat cream and most of the parsley. Mash a few beans against the side of the pot to thicken the sauce.
- Season with salt and plenty of black pepper, then sprinkle over the rest of the parsley and serve in bowls.
Tip Wash the leeks well after slicing, as grit hides between the layers. Leftover oat cream keeps for a few days and is good in soup.
