Add to Collection


  • 3 Tbsp olive oil
  • 6-8 pieces chicken thighs skin-on/bone-in
  • 1/4 cup onion diced
  • 8 oz whole button mushrooms sliced or halved, or left whole if very small
  • 3/4 cup dry white wine
  • 1 1/4 cup chicken stock or broth
  • 3/4 cup heavy cream
  • 2 Tbsp + 1 tsp. grainy mustard (less if using regular Dijon)
  • 2 Tbsp fresh tarragon, chopped (or 1 1/2 tsp. dried)

To thicken (if necessary):

  • 1 Tbsp cornstarch


  • Preheat oven to 375 F. and have a baking sheet ready.
  • In a non-stick skillet, heat 2 Tbsp. olive oil over medium-high heat until very hot. Add chicken, skin side down and cook until golden brown, about 5 minutes. Flip and cook the other side 2-3 minutes. Remove to baking sheet. Place in preheated oven to cook further while you make the sauce. 
  • Remove all but 1 Tbsp of fat from the skillet. Heat skillet over medium-high heat. Add mushrooms and cook until golden, stirring often. Add onion and cook a minute or so more, or until the onion has softened . Add wine and cook over medium-high heat until only a few tablespoons remain. Add the chicken stock, cream, mustard and tarragon. Bring to a boil then reduce heat to medium and allow to cook until the sauce is reduced by half, stirring occasionally (this may take 10 minutes or so). Taste sauce and add salt and pepper, as needed.
  • Note: If sauce is not thick enough, combine 1 Tbsp cornstarch with a Tbsp or so of the sauce and stir until smooth. Return mixture to skillet and cook, stirring, until sauce thickens. Repeat as needed. If serving over pasta or rice, don't make the sauce too thick, so that when spooned over, it seeps to coat the rice or pasta.
  • Remove chicken from oven and place on a serving platter or dish. Pour sauce over-top. Garnish with additional tarragon. Serve over buttered noodles, pasta or rice.
