Recipe Information
Ingredients
- 6 pieces Chicken thighs (bone-in, skin-on)
- 3 tablespoons Unsalted butter
- 2 tablespoons Olive oil
- 2 medium Leeks (white and light green parts, sliced thin)
- 3 medium Carrots (peeled, sliced into rounds)
- 2 stalks Celery stalks (sliced)
- 1 cup Button mushrooms (cleaned and halved)
- 3 cloves Garlic (minced)
- 1 cup Dry white wine
- 2 cups Chicken stock
- 0.75 cup Heavy cream
- 1 tablespoon Whole-grain Dijon mustard
- 2 pieces Bay leaves
- 4 sprigs Fresh thyme sprigs
- 1 teaspoon Salt
- 0.5 teaspoon Black pepper
- 2 tablespoons All-purpose flour
- 2 tablespoons Fresh parsley (chopped, for garnish)
Instructions
Preheat your oven to 375°F (190°C).
Pat the chicken thighs dry with a paper towel and season them with salt and pepper on both sides.
In a large oven-safe casserole dish or Dutch oven, heat 2 tablespoons of butter and 2 tablespoons of olive oil over medium-high heat.
Add the chicken thighs to the dish, skin-side down, and sear for 5-6 minutes until golden brown. Flip and sear the other side for 3-4 minutes. Remove the chicken and set aside on a plate.
Reduce the heat to medium. Add the remaining 1 tablespoon of butter to the dish, followed by the sliced leeks, carrots, celery, and mushrooms. Cook for 7-8 minutes, stirring frequently, until the vegetables are softened.
Stir in the minced garlic and sprinkle the flour over the vegetables. Cook for 1-2 minutes, stirring constantly, to eliminate the raw flour taste.
Deglaze the dish by pouring in the white wine. Scrape the bottom with a wooden spoon to release any browned bits. Simmer for 3-4 minutes until the wine is reduced by half.
Pour in the chicken stock, heavy cream, and Dijon mustard. Stir well to combine.
Add the bay leaves and thyme sprigs to the dish. Return the seared chicken thighs to the casserole, placing them skin-side up on top of the vegetables.
Season with additional salt and pepper if needed. Cover the dish with a lid or foil and place it in the preheated oven.
Bake for 35 minutes, then uncover and bake for an additional 10 minutes to allow the chicken skin to crisp up.
Remove the casserole from the oven and discard the bay leaves and thyme sprigs. Garnish with chopped parsley before serving.
Serve hot with crusty bread or over a bed of rice or mashed potatoes.
