Pour in chicken broth and gently scrape up any browned bits from the pan with a wooden spoon. Allow the broth to reduce slightly.
Stir in the heavy cream and let the sauce simmer gently until thickened and velvety.
Nestle the chicken thighs back into the creamy mushroom sauce. Reduce heat to low, cover, and cook for 10-12 minutes until the chicken is cooked through and tender.
Sprinkle chopped fresh parsley or thyme over the top before serving directly from the skillet.
Notes
For added depth, consider a splash of lemon juice or a pinch of red pepper flakes in the sauce.
