Preheat the oven to 425F/220C, line a baking sheet with parchment paper.
Begin by halving the chicken breast horizontally, creating thinner pieces. Set them aside.
1 1/2 lb chicken breast
In a large mixing bowl, combine the mayonnaise, Dijon mustard, and a pinch of salt and pepper. Mix until these wet ingredients are well combined.
2 tbsp mayonnaise, 1 tsp Dijon mustard
Add the chicken to the wet mixture and use a silicone spatula to coat each chicken breast thoroughly with the mayo and mustard mixture. Ensure that they are evenly coated.
In a shallow bowl, whisk together the dry ingredients: panko breadcrumbs, parmesan cheese, Italian seasoning, garlic powder, smoked paprika, salt, and black pepper. Mix until everything is well combined.
3/4 cup panko breadcrumbs, 1/2 cup parmesan cheese, 1 tsp Italian Seasoning, 1 tsp garlic powder, 1 tsp smoked paprika, 1/2 tsp salt, 1/4 tsp black pepper
Dredge each chicken breast piece in the dry mixture, pressing the breadcrumb mixture onto the chicken to fully cover it. Coat each piece evenly with the seasoned panko mixture.
Transfer the chicken breast pieces to the prepared baking sheet and drizzle or brush with olive oil.
1 tbsp olive oil
Bake the chicken in the preheated oven for 20-25 minutes until it has a beautifully golden-brown crust or until it is cooked through.
