Ingredients You Need

Chicken

2 pounds bone-in, skin-on chicken thighs
- Use thighs for juicy meat and crispy skin.
- Swap with bone-in chicken drumsticks or boneless thighs, but adjust cooking time slightly.

Pantry and fridge ingredients

2 tablespoons olive oil
1 tablespoon unsalted butter
1 medium yellow onion, thinly sliced
3 cloves garlic, minced
2 tablespoons Dijon mustard
- Use a smooth, good-quality Dijon; I like Maille or Grey Poupon.
1 tablespoon whole grain mustard
- Optional but adds great texture and pops of flavor.
1 cup low sodium chicken broth
1 cup heavy cream
- Swap with half and half for a lighter sauce, but it thickens a bit less.
1 teaspoon fresh thyme leaves, or ½ teaspoon dried thyme
1 teaspoon fresh rosemary, finely chopped, or ½ teaspoon dried rosemary
1 teaspoon kosher salt, plus more to taste
½ teaspoon freshly ground black pepper
1 teaspoon lemon juice, to finish
1 teaspoon Dijon mustard extra, to adjust flavor at the end if needed

Optional flavor boosters

1 teaspoon honey, if you like a slightly softer, rounder mustard flavor
1 teaspoon smoked paprika, if you want a subtle smoky note
2 tablespoons chopped fresh parsley, for garnish

Equipment list

Large heavy skillet or sauté pan (12 inch works best)
Tongs for turning chicken
Wooden spoon or silicone spatula
Cutting board and sharp knife
Small whisk for the sauce
Instant read thermometer, helpful for checking doneness

Quick Tips & substitutions

Pat the chicken very dry so the skin browns and crisps instead of steaming.
Brown the chicken in batches if your pan feels crowded, so each piece gets good color.
Use full fat cream for the thickest, silkiest mustard sauce.
Stir the mustard into the cream off the direct heat first, then return to the pan to keep the sauce smooth.
Taste the sauce at the end and adjust with extra Dijon, salt, or a squeeze of lemon.
Swap thighs with chicken breasts and lower the simmer time so the meat stays juicy.
Use coconut cream instead of dairy cream for a dairy free version, and pick a neutral flavored brand.
Skip whole grain mustard if you only have Dijon; just add an extra teaspoon of Dijon.
Add sliced mushrooms or baby spinach to the pan after browning the chicken for more veggies.
Use dried herbs if fresh herbs feel pricey; just use about half the amount.

How to Make French Mustard Chicken Recipe

Step 1: Season and brown the chicken

Pat the chicken thighs dry with paper towels and season both sides with salt and pepper. Heat the olive oil and butter in a large skillet over medium high heat until the butter foams and sizzles. Place the chicken skin side down and cook about 6 to 8 minutes, until the skin turns deep golden and crisp, then flip and cook the second side for 4 to 5 minutes.

Transfer the browned chicken to a plate and keep it nearby. You want browned bits on the bottom of the pan, since those bits carry flavor into the mustard sauce.

Step 2: Soften the aromatics

Lower the heat to medium. Add the sliced onion to the same skillet and cook, stirring often, until the onion turns soft and lightly golden, about 5 to 7 minutes. Add the minced garlic and cook 30 seconds to 1 minute, until it smells fragrant.

If the pan looks dry or the onions start to catch, splash in a tablespoon of broth and scrape up the browned bits with a wooden spoon. Those bits will melt into the sauce and deepen the flavor.

Step 3: Build the mustard cream base

Pour in the chicken broth and stir, scraping the bottom of the pan to loosen any remaining browned bits. Let the broth simmer for 2 to 3 minutes so it reduces slightly. In a small bowl, whisk together the heavy cream, Dijon mustard, and whole grain mustard until smooth.

Pour the cream and mustard mixture into the skillet with the onions and garlic. Stir in thyme, rosemary, and any optional smoked paprika or honey if you use them. Bring the sauce to a gentle simmer over medium heat.

Step 4: Simmer the chicken in the sauce

Nestle the browned chicken thighs back into the skillet, skin side up, along with any juices from the plate. Spoon a little sauce over the meat, but keep most of the skin above the sauce so it stays somewhat crisp. Lower the heat to medium low so the sauce bubbles gently, not rapidly.

Cook for 15 to 20 minutes, until the chicken reaches 165°F in the thickest part and the sauce thickens. Stir the sauce around the chicken occasionally so it does not stick, and adjust the heat if it bubbles too hard.

Step 5: Finish and adjust the flavor

Once the chicken cooks through, squeeze in the lemon juice and stir it into the sauce. Taste the sauce and adjust with a pinch more salt, pepper, or an extra teaspoon of Dijon if you want more tang. If the sauce tastes too strong, add a splash of cream to soften it.

Sprinkle chopped fresh parsley over the top for color and freshness. Turn off the heat and let the chicken sit in the sauce for 3 to 5 minutes so everything settles and thickens slightly more.

Step 6: Serve

Spoon the mustard sauce onto plates or shallow bowls. Place a chicken thigh on top of each pool of sauce, then spoon a little extra sauce over the meat. Serve hot with your favorite sides and something that can soak up every last bit of that mustard cream.

Recipe Variations

Gluten free: Use certified gluten free chicken broth and check mustard labels; serve with rice, potatoes, or polenta.
Dairy free: Swap butter with more olive oil and use coconut cream or a rich oat cream instead of heavy cream.
Lower carb: Serve with cauliflower mash, roasted cauliflower, or sautéed green beans instead of pasta or rice.
Extra veggie: Add sliced mushrooms, leeks, or baby spinach to the pan after the onions soften.
Spicy version: Stir in a pinch of red pepper flakes or a little hot mustard with the Dijon.
Herb swap: Use tarragon or chives instead of rosemary for a slightly sweeter, more classic French bistro vibe.

Ways to Serve French Mustard Chicken Recipe

Spoon over creamy mashed potatoes or cauliflower mash.
Serve with buttered egg noodles or simple steamed rice.
Pair with roasted carrots, green beans, or asparagus.
Serve alongside a crisp green salad with a light vinaigrette.
Tuck leftovers into a warm tortilla or flatbread with lettuce for a quick wrap.

Storage Success

Let the French Mustard Chicken Recipe cool to room temperature, then store it in an airtight container in the fridge for up to 3 days. Reheat it gently on the stove over low heat and add a splash of broth or cream to loosen the sauce. The flavors deepen overnight, so the sauce often tastes even better the next day. If you freeze it, store it up to 2 months and thaw in the fridge before reheating so the sauce stays smooth.
