Creating Pretzel Chicken with Mustard-Cheddar Sauce is a straightforward process. Follow these easy steps to achieve an incredible dish:

1. Preheat the Oven: Set your oven to 400°F (200°C). Line a baking sheet with parchment paper for easy cleanup.
2. Prepare Chicken: Slice the chicken breasts into smaller portions for even cooking and easier serving.
3. Set Up Breading Station: In three separate bowls, prepare the flour, whisked eggs, and pretzel crumbs mixed with garlic powder, onion powder, salt, and pepper.
4. Coat the Chicken: Roll each piece of chicken in the flour, then dip it into the egg, and finally coat it with pretzel crumbs, pressing down to adhere well.
5. Arrange on Baking Sheet: Place the breaded chicken on the lined baking sheet, ensuring they are spaced out evenly.
6. Bake Chicken: Drizzle olive oil over the coated chicken pieces, and bake in the preheated oven for 25-30 minutes, or until they are golden brown and fully cooked through.
7. Prepare the Sauce: While the chicken is baking, mix the mustard, heavy cream, and shredded cheddar cheese in a saucepan over low heat, stirring until the cheese melts and combines into a creamy sauce.
8. Serve the Chicken: Once the chicken is out of the oven, let it rest for a few minutes before serving it with the mustard-cheddar sauce drizzled generously over the top.
