1/2 cup plain panko bread crumbs
1/4 cup roasted sesame seeds
3/4 teaspoon kosher salt, plus more as needed
1/2 teaspoon granulated garlic (a.k.a. garlic powder)
1/2 teaspoon sweet paprika
1/2 teaspoon freshly ground black pepper, plus more as needed
1/4 teaspoon ground cayenne pepper, plus more as needed
2 large eggs
1/3 cup flour
4 boneless, skinless chicken thighs (about 14 ounces total weight, from 1 1/2 pounds bone-in, skin-on chicken thighs; see NOTE)
1/2 cup vegetable oil
Combine the panko, sesame seeds, 1/2 teaspoon of the salt, the garlic powder, paprika, black pepper and cayenne pepper in a shallow dish. Lightly beat the eggs in a separate dish; whisk together the flour and the remaining 1/4 teaspoon of salt in another dish.
Trim any excess fat from the chicken. Season the chicken lightly with salt and black pepper, plus a little more cayenne, if desired. Working with one piece at a time, place each thigh between two sheets of plastic wrap and pound to an even thickness of about 1/4 inch.
Coat each piece of pounded chicken first in the flour mixture, shaking off any excess; then in the egg; and then in the seasoned panko, pressing so the meat is evenly and completely coated. Place on a rimmed baking sheet; let the pieces sit for 10 minutes (this will help the coating adhere during cooking). Discard any remaining egg and seasoned flour; you should have used all the panko mixture.
When you are ready to fry, place a wire rack over a rimmed baking sheet. Heat the oil until shimmering in a heavy skillet over medium heat.
Lay two of the coated chicken pieces in the pan; fry for about 2 1/2 minutes, until the underside is golden brown, then use tongs to turn them over and cook for 1 to 2 minutes on the other side. Transfer to the wire rack to drain while you cook the remaining chicken.
Serve warm, or at room temperature.
