01 - Preheat oven to 400°F. Lightly grease a baking dish or line it with parchment paper.
02 - Pat chicken thighs dry with paper towels and season both sides with salt and pepper.
03 - In a mixing bowl, combine panko breadcrumbs, Parmesan cheese, parsley, rosemary, thyme, minced garlic, olive oil, salt, and black pepper. Stir mixture thoroughly until evenly combined.
04 - Firmly press the herb crust onto the skin side of each chicken thigh, ensuring a uniform coating.
05 - Place crusted chicken thighs, skin side up, into the prepared baking dish in a single layer.
06 - Bake for 30 to 35 minutes, or until the crust is golden and chicken is cooked through with an internal temperature of 165°F.
07 - While chicken bakes, melt butter in a saucepan over medium heat. Sauté minced garlic in butter until fragrant, about 1 minute.
08 - Add chicken broth and bring to a simmer, allowing it to reduce by half. Stir in heavy cream, Dijon mustard, and Parmesan cheese; simmer for 3 to 4 minutes until slightly thickened. Season with salt and pepper.
09 - Transfer baked chicken to a serving platter. Spoon creamy garlic sauce over or around the chicken. Garnish with chopped fresh herbs and lemon wedges if desired.
