Step 1: Prepare the Chicken. Start by preheating your oven to 400°F (200°C). Place the chicken breasts in a mixing bowl. If desired, gently pound them for even thickness.
Step 2: Make the Glaze. In a separate bowl, combine 1 tablespoon of Dijon mustard, 1 tablespoon of mayonnaise, and 1 tablespoon of honey. Mix until smooth.
Step 3: Coat the Chicken. Using a brush or your hands, evenly coat each chicken breast with the honey mustard mixture.
Step 4: Prepare the Coating Mixture. In another bowl, combine finely chopped pecans, panko breadcrumbs, paprika, garlic powder, salt, and black pepper. Mix well.
Step 5: Crust the Chicken. Press each glazed chicken breast firmly into the pecan-breadcrumb mixture until well-coated.
Step 6: Bake. Place the coated chicken on the prepared baking sheet and bake for about 25-30 minutes until cooked through and golden brown.
Step 7: Prepare the Drizzle (Optional). Whisk together the remaining Dijon mustard, mayonnaise, and honey for an optional drizzle.
Step 8: Serve and Enjoy. Let the chicken rest for a few minutes and serve with your favorite sides.
