This creamy mustard chicken is made with juicy boneless chicken thighs simmered in a rich Dijon mustard cream sauce. It’s a one-pan dinner with deep flavor, a silky sauce, and just enough tang from the mustard.
Heat 1 tablespoon extra virgin olive oil and 1 tablespoon butter in a large skillet over medium-high heat.
Season 1 pound (500 g) boneless chicken thighs with 1 teaspoon salt and ½ teaspoon black pepper. Add the chicken to the skillet and cook for 4–5 minutes per side until golden brown and cooked through. Remove from the pan and set aside.
Add the remaining 1 tablespoon butter to the same skillet. Stir in 1 finely chopped onion with ½ teaspoon salt and cook until softened.
Add 3 minced garlic cloves and cook for 1 minute until fragrant.
Pour in ⅓ cup (100 ml) white wine and scrape up the browned bits from the bottom of the pan.
Add 1 cup (250 ml) chicken broth and bring to a gentle simmer.
Return the chicken thighs to the skillet. Stir in 1 teaspoon Dijon mustard and 1 teaspoon whole-grain Dijon mustard until fully combined.
Reduce the heat to medium-low and pour in ⅔ cup (150 ml) heavy cream. Simmer for a few minutes until the sauce thickens slightly and coats the chicken.
Garnish with freshly chopped parsley and serve warm.
Notes
Brown the Chicken Well: I like to give the chicken enough time to turn golden on both sides before removing it from the pan. It makes the sauce taste much richer.Keep the Sauce Gentle: Once I add the cream, I lower the heat and let the sauce simmer gently so it stays smooth and creamy.Use Both Mustards: I like using smooth Dijon and whole-grain Dijon together because one gives the sauce creaminess and the other adds texture.Scrape Up the Pan Bits: After adding the wine, I always scrape the bottom of the pan well because that is where a lot of the flavor is.
