Spray a large sheet pan with non stick cooking spray.
In a bowl, mix mustard, mayonnaise and Worcestershire sauce until well blended. Taste add more mayo if too tart.
2In another bowl, mix Panko's with the seasonings.
3Liberally coat each thigh with mustard mixture ( I just scoop some up with my hand and slather all over thigh. ) Then dip to coat in seasoned crumbs.
4Repeat and place evenly on baking sheet.
5Place in oven and bake for 15 minutes. Carefully turn each piece of chicken and bake on that side for 15 minutes. Repeat until chicken is cooked through and juices run clear. Mine took about 45 minutes in all and they were large thighs. They should be crispy and golden I sprinkled chicken with kosher salt, while hot.
