Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
In a shallow bowl, combine the pretzel crumbs, breadcrumbs, garlic powder, onion powder, paprika, salt, and black pepper. Mix well until evenly combined.
In another bowl, whisk together the buttermilk, Dijon mustard, and half the honey (reserve the other half for drizzling later).
Take each chicken breast and dip it into the buttermilk mixture, making sure it’s well coated. Shake off any excess.
Immediately transfer the chicken to the pretzel crumb mixture, pressing down gently to ensure the coating adheres well. Place the coated chicken breasts on the prepared baking sheet.
Lightly spray the chicken with cooking spray (or drizzle a bit of oil on top) to enhance browning. Bake in the preheated oven for 20-25 minutes, or until the chicken has an internal temperature of 165°F (74°C) and is golden brown.
While the chicken is baking, prepare the honey mustard dip by combining the remaining honey with Dijon mustard in a small bowl. Mix until smooth and well combined.
Once cooked, remove the chicken from the oven and allow it to rest for a few minutes. Slice the chicken and serve warm with the honey mustard on the side for dipping.
Notes
For extra flavor, let the chicken marinate in the buttermilk mixture for 30 minutes before coating.
