Follow these simple steps to create your very own Pretzel Chicken with Mustard-Cheddar Sauce:

1. Preheat the Oven: Begin by preheating your oven to 400°F (200°C). Line a baking sheet with parchment paper for easy cleanup.
2. Prepare Chicken: Take the chicken breasts and pound them to an even thickness for uniform cooking. Season both sides with salt and pepper.
3. Set Up Breading Station: In one bowl, place the flour mixed with garlic powder, onion powder, paprika, salt, and pepper. In a second bowl, whisk together the eggs and milk. In a third bowl, add the pretzel crumbs.
4. Bread the Chicken: Dredge each chicken breast in the flour mixture, shaking off the excess. Then dip into the egg mixture, allowing any excess to drip, and finally coat with pretzel crumbs, pressing gently to adhere.
5. Arrange on Baking Sheet: Place the breaded chicken breasts onto the prepared baking sheet and drizzle with olive oil.
6. Bake Chicken: Bake in the preheated oven for about 25-30 minutes or until the chicken is cooked through and reaches an internal temperature of 165°F (75°C).
7. Prepare the Sauce: While the chicken bakes, in a medium saucepan, combine shredded cheddar cheese, Dijon mustard, and sour cream over medium-low heat. Stir until the cheese melts and the sauce is smooth. Season with salt and pepper to taste.
8. Plate the Dish: Once the chicken is done, remove it from the oven and let it rest for a few minutes. Serve the chicken on a plate and drench it in the mustard-cheddar sauce.
9. Garnish: If desired, sprinkle with fresh parsley for an added touch of color and flavor.
