Instructions

1. Season the chicken thighs all over with the salt and black pepper.
- 2
2. Heat a large skillet over medium-high heat and add the olive oil. Brown the chicken for 2 to 3 minutes per side, just until lightly colored; it does not need to cook through. If preferred, you may skip this step and place the chicken directly in the slow cooker, but the flavor will be less developed.

3. Transfer the chicken to the slow cooker. Add the leek, pear, garlic, chicken broth, whole grain mustard, and fresh thyme. Stir gently to distribute the ingredients around the chicken.

4. Cover and cook on LOW for 4 hours, maintaining a gentle slow-cooking environment of about 190 to 200 °F / 88 to 93 °C inside the cooker, until the chicken is tender.

5. Open the slow cooker and add the heavy cream. Mix the cornstarch with the water in a small bowl until smooth and pour it into the cooker. Stir carefully to combine the cream and cornstarch slurry without breaking up the chicken too much.

6. Cover again and cook for 20 more minutes on HIGH, aiming for an active cooking temperature close to 205 to 212 °F / 96 to 100 °C, until the sauce thickens slightly.

7. Taste and adjust with more salt or pepper if needed. Sprinkle the fresh parsley over the top just before serving.

8. Serve hot, spooning plenty of sauce, soft leek, and tender pear pieces into each portion.
Chef tips
For a looser, shinier sauce, add an extra tablespoon of broth at the end if it thickens too much. Wash the leek very well between the layers to remove any grit. For a more elegant presentation, dice the pear small so it partially melts into the sauce.
Substitutions
You can swap the pear for a firm apple. The heavy cream can be replaced with plant-based cooking cream, though the flavor will change. If you do not have fresh thyme, use 1 teaspoon dried thyme. Whole grain mustard can be replaced with Dijon mustard, but the texture will be less rustic.
