Step‑by‑Step Instructions for French Mustard Chicken
Step 1: Sear Chicken
Begin by heating a large skillet over medium-high heat. Season the 6 chicken thighs generously with salt and pepper, then add to the hot skillet skin-side down. Sear for about 6–8 minutes until the chicken is golden brown and crispy. Flip and sear the other side for another 5–6 minutes. Once done, remove the chicken from the skillet and set aside.
Step 2: Sauté Aromatics
In the same skillet, lower the heat to medium, then add finely chopped shallots and minced garlic. Sauté them for 2–3 minutes, stirring frequently until the shallots become translucent and fragrant. This step will build the flavor base for your French Mustard Chicken, ensuring every bite is aromatic and delicious.
Step 3: Deglaze & Combine
If using, pour in 0.25 cup of white wine to deglaze the pan, scraping up any browned bits stuck to the bottom. This will intensify the flavors of your sauce. Allow the wine to simmer for about 2 minutes, reducing slightly before moving to the next step. If avoiding alcohol, substitute with chicken broth at this stage.
Step 4: Create Sauce
Stir in 1 cup of heavy cream along with the 2 tablespoons of Dijon mustard and 1 tablespoon of whole grain mustard. Mix well until all the ingredients are fully incorporated and the sauce is creamy. This luscious sauce is essential for your French Mustard Chicken. Allow it to heat through for about 3-4 minutes, but do not let it boil.
Step 5: Simmer
Return the seared chicken thighs back to the skillet, ensuring they are immersed in the sauce. Reduce the heat to low and let everything simmer for about 20 minutes. The chicken should be cooked through and reach an internal temperature of 165°F (75°C), while the sauce thickens and coats each piece beautifully.
Step 6: Serve
Once the chicken is tender and the sauce is at your desired consistency, remove from heat. Serve your delicious French Mustard Chicken immediately, allowing the creamy mustard sauce to soak into mashed potatoes or buttered noodles. Enjoy the comforting flavors and aroma with your loved ones!

French Mustard Chicken Recipe FAQs
How do I choose the best chicken thighs for this recipe?
Absolutely! When selecting chicken thighs, look for pieces that are plump and have a vibrant, pink color with no dark spots. The skin should be intact and smooth. Bone-in, skin-on thighs retain moisture while cooking, ensuring a juicy finished dish.
What are the best ways to store leftover French Mustard Chicken?
You can store leftovers in an airtight container in the refrigerator for up to 3 days. Be sure to let the chicken cool completely before sealing it. This helps maintain the sauce’s creamy texture upon reheating. If you’re planning to keep it longer, follow the freezing method!
Can I freeze French Mustard Chicken, and how do I do it?
Yes, definitely! To freeze, let the chicken cool, then place the portions in a freezer-safe container or wrap tightly in plastic wrap and aluminum foil. It is best to freeze it within 2 hours of cooking. French Mustard Chicken can be stored in the freezer for up to 2 months. When you’re ready to enjoy it again, thaw it overnight in the refrigerator before reheating gently on the stove, adding a splash of cream if needed to bring back that luscious sauce.
What should I do if my sauce curdles while cooking?
If your sauce curdles, don’t worry—this can happen if it gets too hot! To resolve it, remove it from heat immediately. You can attempt to whisk in a bit more cream or broth off the heat to combine it. If it’s very separated, try blending it gently in a food processor or blender to restore its creamy consistency.
Is this recipe suitable for people with dietary restrictions or allergies?
This French Mustard Chicken recipe does contain dairy and mustard, so be sure to consider anyone with lactose intolerance or mustard allergies.
