03 - Combine panko breadcrumbs, Parmesan, chopped parsley, rosemary, thyme, minced garlic, olive oil, salt, and pepper in a mixing bowl and mix thoroughly.
04 - Firmly press the herb mixture onto the skin side of each chicken thigh to ensure an even coating.
05 - Place the coated thighs skin side up in the prepared baking dish.
06 - Bake for 30 to 35 minutes, or until the crust is golden and the chicken is cooked through, reaching an internal temperature of 165°F (75°C).
07 - While chicken is baking, melt butter in a saucepan over medium heat. Sauté minced garlic for 1 minute until aromatic.
08 - Add chicken broth to saucepan, bring to a simmer, and reduce by half. Stir in heavy cream, Dijon mustard, and Parmesan. Simmer 3 to 4 minutes until slightly thickened. Season sauce with salt and pepper to taste.
