Step‑by‑Step Instructions for Creamy Mustard Chicken
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C) to set the perfect stage for cooking your Creamy Mustard Chicken. This temperature is ideal for braising the chicken to tender perfection, allowing the flavors to meld beautifully.
Step 2: Season the Chicken
Take the chicken thighs and generously season them with salt and pepper, ensuring even coverage. Then, rub both Dijon and whole grain mustard all over each thigh, creating a flavorful coating that will enhance the richness of the sauce as it cooks.
Step 3: Brown the Chicken
In a Dutch oven or large oven-proof skillet, melt butter over medium-high heat. Once it’s sizzling, add the chicken thighs skin-side down and brown them for about 4-5 minutes per side until they achieve a golden-brown crust. This step locks in flavor, so transfer the chicken to a plate once browned.
Step 4: Sauté the Aromatics
In the same skillet, add sliced onion and shallot, cooking them over medium heat until they become translucent, which should take about 5 minutes. Stir occasionally for even cooking and to ensure they don’t burn, as they will add essential sweetness and depth to your creamy mustard sauce.
Step 5: Deglaze the Pan
Pour in the chicken broth while scraping any brown bits from the bottom of the pan to release the rich flavors. Add fresh thyme and a bay leaf, stirring well to combine. This step will create the flavorful base for your sauce, enhancing the overall taste of the Creamy Mustard Chicken.
Step 6: Combine the Creamy Elements
Stir in the Crème Fraîche until fully combined, creating a smooth and creamy sauce. Return the chicken thighs to the pan, ensuring they are nestled well within the sauce. This mixture will simmer gently, allowing the chicken to absorb every bit of flavor.
Step 7: Bake the Chicken
Place the skillet in the preheated oven and cook uncovered for 50-60 minutes. Check for doneness; the chicken should be cooked through and no longer pink, reaching an internal temperature of 165°F (75°C). The sauce will bubble gently around the tender chicken, creating a delightful aroma.
Step 8: Garnish and Serve
Once baked, remove the pan from the oven and discard the bay leaf. Garnish with freshly chopped parsley for a vibrant touch. Serve your Creamy Mustard Chicken hot, accompanied by your favorite sides, to enjoy a comforting meal that feels like a warm embrace.

Make Ahead Options
These Creamy Mustard Chicken meal prep options make weeknight cooking a breeze! You can marinate the chicken and prepare the mustard sauce up to 24 hours in advance, allowing the flavors to meld beautifully. Simply season the chicken thighs with salt, pepper, and mustards, then refrigerate. You can also sauté the onions and shallots the day before and store them in an airtight container. When you’re ready to serve, combine the sautéed aromatics with chicken broth, herbs, and crème fraîche, return the marinated chicken to the pan, and bake as directed. This way, you’ll enjoy a restaurant-quality dish with minimal effort, just as delicious as if you made it fresh!
