Start by browning the chicken thighs in a frying pan with the vegetable oil. Cook them on each side for about 2-3 minutes until golden brown.
2 tbsp vegetable oil, 8 boneless chicken thighs
Once browned, transfer the chicken thighs to a slow cooker.
In the same pan, melt the unsalted butter over medium heat. Add the diced onions, minced garlic, and sliced celery. Cook until the onions are softened and translucent.
2 tbsp unsalted butter, 2 brown onions, 3 cloves of garlic
Sprinkle the plain flour over the onions, garlic, and celery. Stir to coat and cook for another 2 minutes to cook off the raw flour taste.
3 tbsp plain flour
Add the salt, black pepper, dried thyme, and celery salt to the pan. Stir to combine with the flour and vegetable mixture.
1 teaspoon salt, 1/2 teaspoon black pepper, 1/2 teaspoon dried thyme, 1/2 teaspoon celery salt
Pour in the chicken stock and freshly squeezed lemon juice. Stir well to incorporate all the ingredients.
500 ml chicken stock, 2 tablespoons freshly squeezed lemon juice
Transfer the mixture from the pan to the slow cooker with the chicken thighs.
Add the baby chestnut mushrooms, halved chantenay carrots, and sliced celery to the slow cooker. Stir gently to distribute the vegetables evenly.
200 g baby chestnut mushrooms, 200 g chantenay carrots, 2 celery stalks
Cover the slow cooker and cook on low heat for 5-6 hours or high heat for 3-4 hours, until the chicken is tender and the flavors have melded together.
Once cooked, remove the chicken thighs from the slow cooker and shred them using two forks.
Stir in the double cream to add richness to the sauce.
100 ml double cream
Return the shredded chicken to the slow cooker and stir to combine.
