Heat ½ tbsp oil in a large frying pan, cook 1 finely chopped large onion for 8-10 mins until softened and starting to caramelise.

Meanwhile, put 1½ tbsp flour and a little salt and pepper in a bowl and toss chicken in it.

Add garlic and the chicken to the pan and cook for 4-5 mins more until the chicken is starting to brown.

Give it a good stir. Cook on Low for 7 hours or High for 4 hours.

Remove the bay leaves and serve with a little Dijon mustard on the side
