Creating the Crispy Dill Chicken Sandwich is simple if you follow these steps:

1. Marinate Chicken: In a bowl, combine the buttermilk and chicken breasts. Allow to marinate for at least 30 minutes (or up to overnight in the refrigerator).
2. Prepare Breading: In a shallow dish, mix the flour, dried dill, garlic powder, onion powder, smoked paprika, salt, and pepper.
3. Coat Chicken: Remove the chicken from the marinade, allowing excess buttermilk to drip off. Dredge each piece in the flour mixture, ensuring it is fully coated.
4. Coat with Breadcrumbs: Dip each floured chicken piece into the breadcrumbs, pressing gently to adhere. Place on a plate and let rest for 10 minutes.
5. Heat Oil: In a large skillet, heat about 1/2 inch of vegetable oil over medium-high heat until hot.
6. Fry Chicken: Carefully add the chicken pieces to the skillet. Fry for 5-7 minutes on each side or until golden brown and cooked through. Use a meat thermometer to ensure the internal temperature reaches 165°F (75°C).
7. Drain: Once cooked, transfer the chicken to a paper towel-lined plate to drain excess oil.
8. Make the Creamy Dill Sauce: In a small bowl, combine mayonnaise, chopped dill, lemon juice, salt, and pepper. Mix well and adjust seasoning to taste.
9. Assemble Sandwiches: Spread creamy dill sauce on the bottom half of each sandwich bun. Place a piece of crispy chicken on top, followed by lettuce, tomato, and dill pickle slices. Top with the other half of the bun.
10. Serve: Enjoy your Crispy Dill Chicken Sandwich while it’s hot and crispy.
