Ingredients You’ll Need
These ingredients are straightforward and pantry-friendly, yet each one plays a vital role in shaping the taste, texture, and aroma of your roasted chicken. From the creamy tang of mustards to the warmth of herbs and the essential olive oil, every need is thoughtfully covered.
- 6 boneless/skinless chicken thighs: Tender and perfect for roasting, they absorb flavors beautifully while staying juicy throughout cooking.
- 2 heaping tablespoons grainy mustard: Adds a mild tang and lovely texture with its mustard seeds, I recommend Maille Old Style for authenticity.
- 1 heaping tablespoon Dijon mustard: Gives sharp, smooth flavor that blends seamlessly with the grainy mustard for balanced complexity.
- 1 tablespoon olive oil: Helps the marinade adhere and keeps the chicken moist while roasting to a golden finish.
- 2 dashes Italian seasoning: A blend of herbs like oregano, basil, and rosemary that provide a subtle savory background.
- Salt & pepper: Basic but essential; enhances and brightens every flavor in the dish.
- Fresh thyme: Both the leaves and sprigs are sprinkled on top, adding that fresh, earthy aroma that’s simply irresistible.
How to Make Roasted Mustard Chicken Thighs Recipe
Step 1: Preheat the Oven
Start by setting your oven to 425°F and positioning the rack in the middle. This high temperature is key for roasting the chicken evenly and developing a beautiful, slightly crispy exterior that locks in all those delicious flavors.
Step 2: Marinate the Chicken
Season your chicken thighs generously with salt and pepper, then toss them in a large Ziploc bag with the grainy mustard, Dijon mustard, olive oil, and Italian seasoning. Massage the bag gently to coat every bite with the tangy marinade. Although it’s tempting to roast immediately, letting it hang out in the fridge for 30 minutes or even a few hours will deepen those flavors beautifully.
Step 3: Arrange and Add Fresh Thyme
Spread the marinated chicken thighs in an even layer inside a baking dish. Sprinkle fresh thyme leaves over them, and don’t hesitate to tuck a few whole sprigs on top. Thyme’s aromatic presence will infuse the chicken as it roasts, giving the dish an irresistible herbaceous lift.
Step 4: Roast to Perfection
Place your baking dish in the oven and roast for 20 to 25 minutes, or until the internal temperature reaches 175°F. This ensures the chicken is perfectly cooked, juicy on the inside, and nicely browned on the outside. After roasting, allow the chicken to rest a few minutes before serving to lock in all those juices.
How to Serve Roasted Mustard Chicken Thighs Recipe

Garnishes
Simple garnishes can elevate your presentation and flavor. Fresh thyme sprigs add a lovely visual touch and enhance aroma when served warm. A light drizzle of extra mustard or a wedge of lemon can add brightness, balancing the richness of the chicken beautifully.
Side Dishes
This dish pairs wonderfully with a variety of sides. Creamy mashed potatoes or buttery roasted vegetables soak up the tangy mustard sauce perfectly. For a lighter option, a crisp green salad dressed with vinaigrette or a medley of steamed seasonal vegetables works like a charm.
Creative Ways to Present
If you want to treat your guests or family to a bit of culinary theater, serve your roasted mustard chicken thighs atop a bed of fluffy couscous or wild rice. Drizzle some extra pan juices or a quick mustard sauce over the top, and sprinkle with chopped fresh herbs for a pop of color and flavor that truly wows.
Make Ahead and Storage
Storing Leftovers
After enjoying this Roasted Mustard Chicken Thighs Recipe, pack any leftovers into an airtight container and keep them in the refrigerator. Properly stored, the chicken will stay flavorful and juicy for up to 3 days.
Freezing
If you’d like to make this dish ahead or save portions for another day, freezing is a great option. Place cooled chicken thighs in a freezer-safe container or heavy-duty bag and freeze for up to 2 months. Just be sure to thaw overnight in the fridge before reheating.
Reheating
For reheating, gently warm the chicken in a low oven (around 325°F) or microwave, covered, to retain moisture. Avoid overheating to prevent drying out the tender thighs. A splash of water or chicken broth during reheating can help keep things juicy.
FAQs
Can I use bone-in chicken thighs for this recipe?
Absolutely! Bone-in thighs will take a bit longer to cook, around 30-35 minutes, but they add extra flavor and stay juicy. Just be sure to check for doneness with a meat thermometer.
Is it necessary to marinate the chicken?
While not mandatory, marinating for at least 30 minutes allows the mustard and herbs to deepen their flavor penetration, making the chicken tastier and more aromatic.
Can I use other herbs besides thyme?
Yes! Rosemary, oregano, or tarragon all work wonderfully with mustard and chicken. Feel free to experiment with what you have on hand to tailor the flavor to your liking.
How can I make this recipe gluten-free?
This Roasted Mustard Chicken Thighs Recipe is naturally gluten-free as long as you use a mustard brand without any gluten-containing additives. Always check labels to be certain.
What side dish pairs best with the mustard flavors?
Potatoes—roasted, mashed, or even fries—are a classic pairing that balance the mustard’s tang nicely. Additionally, a simple sautéed green vegetable or a light pasta salad complements the dish without overpowering it.
