Step 1

Preheat the oven to 450 degrees F (230 degrees C).

Step 2

Season chicken breasts on both sides with salt, black pepper, and cayenne.

Step 3

Heat olive oil in an oven-safe skillet over high heat. Add chicken breasts. Sear, untouched, until bottoms release from the pan, about 2 minutes. Flip and cook for 2 minutes more.

Step 4

Reduce heat to medium-low. Add butter and let melt. Add panko bread crumbs. Cook and stir until breadcrumbs start to turn golden, 2 to 3 minutes. Stir in garlic and cook until fragrant, about 1 minute. Turn off heat and add parsley and Parmigiano-Reggiano. Set breading aside.

Step 5

Combine mayonnaise, balsamic vinegar, and Dijon mustard in a small bowl. Spread 'glue' over the top and sides of the chicken breasts. Spoon over the the breadcrumb mixture. Use a spatula to transfer chicken breasts back to the skillet. Pour chicken broth around the chicken.

Step 6

Bake in the preheated oven until no longer pink in the center, 10 to 12 minutes. An instant-read thermometer inserted into the chicken should read at least 165 degrees F (74 degrees C). Transfer chicken to a plate and let rest while you make the pan sauce.

Step 7

Pour chicken broth and lemon juice into the pan. Bring to a boil over high heat and add balsamic vinegar. Boil until sauce is reduced, about 2 minutes. Strain sauce and spoon around chicken.
