For the Base

Step‑by‑Step Instructions for French Mustard Chicken
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This ensures the French Mustard Chicken cooks evenly and develops those rich flavors. While the oven is heating, you can prepare your other ingredients, making efficient use of your time.
Step 2: Season the Chicken
Generously season the chicken thighs with salt and pepper on both sides. Then, rub the Dijon and whole grain mustards all over the chicken, ensuring each piece is nicely coated. This step is crucial for infusing the chicken with that signature mustard flavor which will truly elevate your dish.
Step 3: Brown the Chicken
In a large Dutch oven, melt the butter over medium-high heat. Once the butter is bubbly, add the chicken thighs skin-side down and brown for 4–5 minutes until golden. Flip the thighs to brown the other side for another 4–5 minutes. Remove the chicken from the pot and set aside on a plate as you prepare the sauce.
Step 4: Sauté the Aromatics
In the same pot, add the sliced onion and shallot, sautéing for about 5 minutes until they become translucent and fragrant. Quickly scrape the bottom of the pot with a wooden spoon to lift any browned bits, as they contribute wonderful flavor to the creamy mustard sauce.
Step 5: Build the Sauce
Add the chicken broth to the pot, scraping away any remaining brown bits from the bottom. Toss in the fresh thyme sprigs and bay leaf, then elevate the heat to bring the mixture to a gentle boil. This step helps marry the flavors and prepares for the rich sauce that will envelop the chicken.
Step 6: Combine Chicken and Sauce
Stir in the crème fraîche until it’s fully dissolved into the broth, creating a velvety sauce. Return the browned chicken thighs to the pot, skin-side up, making sure they’re nestled into the sauce. This is where the chicken absorbs the delicious flavors, making the dish shine.
Step 7: Bake to Perfection
Cover the Dutch oven with its lid and transfer it to the preheated oven. Cook the French Mustard Chicken for 50–60 minutes, or until the chicken reaches an internal temperature of 165°F (75°C). You’ll know it’s done when the meat is tender and juicy, and the sauce is bubbling.
Step 8: Garnish and Serve
Once cooked, remove the pot from the oven and discard the bay leaf. Garnish the dish with chopped parsley for a fresh pop of color. Serve the creamy mustard chicken warm, spooning generous amounts of sauce over the chicken. This dish pairs beautifully with mashed potatoes or crusty bread.

French Mustard Chicken Recipe FAQs

Absolutely! You can freeze French Mustard Chicken for up to 3 months. I recommend portioning it into freezer-safe containers for easy access later. Don’t forget to label each container with the date! When ready to eat, thaw in the fridge overnight and reheat on the stove until heated through.

If you find the sauce too thick, no worries! Simply stir in a little chicken broth or water a tablespoon at a time until you reach your desired consistency. This way, you’ll keep the creamy texture while adjusting the richness to your liking.
Are there any dietary considerations for this recipe?
This recipe is generally family-friendly; however, if anyone in your group has mustard allergies, you can still enjoy the dish by substituting Dijon mustard with a mix of mayonnaise and a splash of vinegar for a similar tanginess. Additionally, for a dairy-free version, use coconut cream in place of crème fraîche.
