1 bouquet garni, consisting of fresh rosemary, thyme, sage and bay leaf
1 cup chicken stock
kosher salt and freshly ground black pepper to taste
Method
Place the chicken thighs, skin-side down, into a skillet. Cook until browned, 2 to 4 minutes per side. Transfer chicken to a plate; drain and discard all but 1 tablespoon drippings from the skillet.
Lower the heat to medium-high; sauté mushrooms, onion, and shallots with a pinch of salt in the hot skillet until golden and caramelised, 7 to 12 minutes. Add the garlic and cook for a couple more minutes.
Stir flour and vegan butter into vegetable mixture until completely incorporated, about 1 minute.
Add the wine and stock and bring to a boil.
Put the chicken, onions and mushrooms into the slow cooker and add the wine, stock and herbs.
