Season 4 Chicken thighs with 2 pinch of Sea salt and ground black pepper.
Heat 2 tbsp of Olive oil in a pan over a medium heat and add the chicken. Brown for 4 minutes, then turn over and brown for a further 3 minutes.
Put the browned chicken thighs into the slow cooker.
Add 1 Onion, 2 Carrot, 220 g of Button mushrooms and 3 Garlic clove to the slow cooker.
In a jug, mix together 400 ml of Chicken stock, 175 ml of White wine, 200 g of Chopped tomatoes, 1 tbsp of Tomato puree and 0.5 tsp of Dried thyme.
Pour the stock into the slow cooker and carefully mix everything together, ensuring the chicken doesn't break.
Cook on high for 4 hours.
Notes
This might not look like a lot of liquid to add, but slow cooking doesn't release a lot of liquid, so if you add too much then the finished dish will have too much liquid.
If your chicken chasseur is too thin, you can add a cornflour slurry to it or even some gravy granules.
