A comforting one-pan chicken dish featuring golden seared chicken breasts smothered in a rich, garlicky mushroom cream sauce brightened with lemon and Dijon mustard — the perfect cozy yet elegant weeknight meal.

Ingredients

2 large boneless, skinless chicken breasts

1 tablespoon olive oil

2 tablespoons butter

8 oz cremini or white mushrooms, sliced

3 cloves garlic, minced

½ cup chicken broth

¼ cup lemon juice

¾ cup heavy cream

1 teaspoon Dijon mustard

1 tablespoon cornstarch + 2 tablespoons cold water (slurry)

Salt and pepper, to taste

Fresh thyme or parsley, for garnish

Instructions

  1. Season chicken breasts with salt and pepper on both sides.
  2. Heat olive oil in a large skillet over medium-high heat. Sear chicken for 4–5 minutes per side until golden brown. Remove and set aside.
  3. Reduce heat to medium and add butter. Once melted, add mushrooms and sauté for 5–7 minutes until golden and tender.
  4. Add minced garlic and cook for 30 seconds until fragrant.
  5. Pour in chicken broth and lemon juice, scraping up browned bits. Simmer for 2 minutes to reduce slightly.
  6. Stir in Dijon mustard and heavy cream. Bring to a gentle simmer, then whisk in cornstarch slurry to thicken.
  7. Return chicken to the pan, spoon sauce over top, and cover. Simmer for 8–10 minutes until chicken is cooked through and sauce is silky.
  8. Garnish with fresh thyme or parsley and serve with mashed potatoes, rice, or pasta.

Notes

Substitute chicken thighs for a juicier result.

Use coconut cream for a dairy-free version.

Add spinach, asparagus, or sun-dried tomatoes for variety.

Lower heat before adding cream to prevent curdling.

Reheat gently with a splash of broth or cream to keep sauce smooth.
