Start by slicing and pounding the chicken breasts until they are thin and even. This helps them cook quickly and evenly without drying out. Lightly season both sides with salt and pepper, keeping it minimal due to the salty coating.
Add pretzels to a blender or food processor and pulse until mostly fine crumbs form. Avoid leaving large chunks because they can burn quickly during frying. The texture should resemble coarse breadcrumbs for the best crunch.
In a bowl, whisk together eggs, mustard, and honey until smooth. This mixture acts as a flavorful glue that helps the pretzel coating stick properly. It also adds a subtle sweet and tangy flavor to the chicken.
Dip each chicken piece into the egg mixture, ensuring it’s fully coated. Then press it into the crushed pretzels, covering all sides evenly. Press gently so the crumbs adhere well and don’t fall off during cooking.
Heat vegetable oil in a large pan over medium-high heat. Fry the chicken for about 3 minutes per side until golden and cooked through. Be careful not to overheat the oil, as pretzels can burn faster than breadcrumbs.
Transfer the cooked chicken onto a wire rack and let it rest for a few minutes. This keeps the coating crispy instead of soggy. Avoid placing it directly on paper towels for best results.
In a small bowl, whisk together Dijon mustard, yellow mustard, mayonnaise, honey, lemon juice, and red pepper flakes. Taste and adjust seasoning if needed. The sauce should be creamy, sweet, tangy, and slightly spicy.
Drizzle the sauce over the crispy chicken or serve it on the side for dipping. Enjoy immediately while the coating is still crunchy and fresh.
