What is French Mustard Chicken?
French Mustard Chicken is a creamy chicken skillet dish that hails from rustic French cooking traditions, but has been simplified for the modern kitchen. It’s made by pan-searing chicken breasts and simmering them in a luscious sauce of Dijon mustard, whole grain mustard, cream, garlic, onions, and herbs. The result is a balanced flavor bomb: tangy, creamy, savory, and slightly earthy thanks to the thyme.
In France, it might be called “Poulet à la Moutarde,” but let’s be honest—we’re keeping it real and calling it what it is: comfort food with a French twist. Unlike overly complicated French recipes, this one doesn’t require wine pairings or culinary school. It’s beginner-friendly, kitchen-tested, and weeknight-approved.
Reasons to Try French Mustard Chicken
Why give French mustard chicken a spot in your dinner rotation? Let’s count the delicious ways. First, it’s fast. We’re talking 45 minutes, start to finish. That’s less time than waiting on delivery. Second, the flavor-to-effort ratio is wildly in your favor. You’re making something that tastes restaurant-level, but uses pantry staples.
Third, it’s super adaptable. Want it spicier? Add a dash of cayenne. Want it lighter? Swap in half-and-half. Got picky eaters? The mustard flavor mellows out into creamy, savory magic that even the skeptics will devour. Plus, this recipe has just enough French flair to make you feel fancy—without needing to iron your napkins or own a Le Creuset.

Season and Sear the Chicken
Pat the chicken breasts dry and season both sides with salt and pepper like you mean it. Heat the olive oil in a large skillet over medium-high heat. Add the chicken and cook about 5 minutes per side, until golden brown and fully cooked (internal temp: 165°F). Remove from the skillet and set aside.
Sauté the Aromatics
In the same skillet, add butter. Once melted, toss in the chopped onion and sauté for about 4 minutes until translucent. Stir in the minced garlic and cook for another minute. Your kitchen will smell amazing.
Deglaze and Simmer
Pour in the chicken broth. Use a wooden spoon to scrape up any of the browned bits stuck to the pan (aka flavor gold). Let that simmer for 3 minutes on low heat.
Make the Mustard Sauce
Now the magic: stir in the heavy cream, Dijon mustard, whole grain mustard, and thyme. Mix it up and let the sauce gently simmer and thicken for 5 minutes. It’ll get creamy and velvety, with mustard speckles that scream “I’m gourmet.”
Return Chicken to the Pan
Place the chicken back in the skillet, turning to coat it in that hypnotic sauce. Let everything simmer together for another 5 minutes so the flavors can get cozy. Garnish with fresh parsley if you’re feeling fancy.
What to Serve with French Mustard Chicken
French mustard chicken is basically begging for a creamy or starchy side to soak up that sauce. Think buttery mashed potatoes, white rice, or even a crusty baguette if you want to channel your inner Parisian. For something green, roasted asparagus or simple steamed green beans work beautifully—they cut through the richness and balance the meal. You could also serve it over egg noodles or with Millionaire Gnocchi with Creamy Sauce for something extra indulgent. Don’t forget a crisp white wine if it’s been that kind of day.
Key Tips for Making French Mustard Chicken
- Don’t skip the sear: Getting a nice golden crust on the chicken locks in flavor and gives texture.
- Use both mustards: The combo of Dijon (smooth) and whole grain (textured) gives depth and bite.
- Cream or bust: Heavy cream adds that silky feel. You can use half-and-half, but don’t go skim milk here.
- Taste as you go: Mustards vary in saltiness. Adjust the seasoning to make it just right.
- No thyme? No panic: Rosemary or tarragon also pair nicely. Use what’s in your spice drawer.
- Want to prep ahead? The sauce can be made the day before and reheated.
Storage and Reheating Tips French Mustard Chicken
Got leftovers? French mustard chicken keeps well and reheats like a dream. Store in an airtight container in the fridge for up to 3 days. The sauce may thicken as it sits, so add a splash of broth or water when reheating. Warm gently on the stovetop over low heat or microwave in 1-minute intervals, stirring between. You can also freeze it (sauce and all) for up to 2 months. Just thaw overnight in the fridge and reheat slowly to keep the sauce creamy—not separated.
FAQs
Can I use chicken thighs instead of breasts?
Yes, absolutely! Thighs will be juicier and add even more richness.
What can I substitute for heavy cream?
Half-and-half works in a pinch. Even coconut cream if you want to experiment (though it’ll alter the flavor).
Is this dish spicy?
Not at all—but you can add red pepper flakes or cayenne if you like a kick.
Can I make this dairy-free?
You can try using unsweetened cashew cream or oat cream. Just know the flavor will shift slightly.
Does this work with pork?
Yes! Pork chops also love mustard sauce. Just adjust the cooking time.
