How to Make Chicken in Mustard Sauce
-
Season Chicken
Generously season the chicken pieces with salt. Next, rub Dijon mustard all over both sides of the chicken to infuse it with flavor. -
Brown the Chicken
In a heavy-bottom pot, melt the butter over medium-high heat. Once hot, add the chicken pieces and brown them for about 5 minutes on each side. Remove the chicken and set it aside. -
Sauté Onions
Lower the heat and add the crispy onions (or sautéed regular onions mixed with flour). Sauté for about 1 minute until fragrant, stirring gently. -
Deglaze the Pot
Pour in the chicken broth and dry white wine. Bring the mixture to a boil and let it reduce for 4-5 minutes to enhance the flavors. -
Combine Ingredients
Stir in whole milk (or your choice of crème fraîche/heavy cream) and add the browned chicken back to the pot. Toss in the thyme and bay leaf for extra flavor. -
Simmer to Perfection
Cover and reduce the heat to medium-low, cooking for 45-50 minutes until the chicken is tender and the sauce has thickened to a sumptuous consistency.
Optional: Serve with a sprinkle of fresh thyme for added color and flavor.
