Position a rack in the center of the oven and preheat the oven to 350 degrees F.

Place the garlic, thyme, salt, and pepper in a food processor and pulse until the garlic is finely minced. Add in the panko, lemon zest, olive oil, and butter and continue to pulse a few times until the breadcrumbs are moistened. Pour the breadcrumb mixture onto a large plate. In a shallow bowl, whisk together the mustard, honey and chicken broth.

Pat the chicken thighs dry with a paper towl. Sprinkle with a little bit of salt and pepper. Dip each piece into the mustard mixture to coat on all side, then place skin-side down only in the crumb mixture, pressing gently to make the crumbs stick. Place the chicken on a sheet pan crumb-side up. Press any remaining crumbs onto the chicken pieces. At this point honey mustard chicken can covered with plastic wrap and refrigerated until ready to bake.

Bake the chicken for 40 minutes. Raise the oven temperature to 400 degrees F and continue to bake for an additional 10 minutes until the crumbs are browned and the chicken is cooked through. Serve warm.
