Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper.
In a shallow dish, combine the flour, garlic powder, paprika, salt, and pepper. In another dish, whisk the eggs until well beaten. In a third dish, pour the crushed pretzels.
Dip each chicken breast into the flour mixture, shaking off excess, then into the beaten eggs, and finally coat with the crushed pretzels, pressing gently to adhere.
Heat olive oil in a large skillet over medium heat. Add the pretzel-coated chicken breasts and cook for about 3-4 minutes on each side until golden brown. Transfer the chicken to the prepared baking sheet.
Bake the chicken in the preheated oven for 15-20 minutes, or until the internal temperature reaches 165°F (75°C).
While the chicken is baking, prepare the mustard cheddar sauce: In a saucepan over medium heat, combine the milk, Dijon mustard, and honey. Stir in the cheddar cheese and cook until melted and smooth. Remove from heat.
Once the chicken is done, remove from the oven and drizzle the mustard cheddar sauce over the top or serve it on the side for dipping.
Notes
Serve the chicken on a wooden board for rustic charm, garnished with fresh parsley.
