Make the best homemade chicken sandwich with a super crispy coating and a bright, fresh dill flavor. This recipe uses buttermilk marinade for tender chicken.
Place chicken pieces in a bowl. Pour buttermilk and hot sauce over the chicken. Cover and refrigerate for at least 4 hours, or overnight for best results.
In a shallow dish, whisk together flour, cornstarch, salt, pepper, dried dill weed, garlic powder, onion powder, and cayenne pepper if using. This is your crunchy chicken coating secrets base.
Remove chicken from the marinade, letting excess drip off, but do not pat dry. Dredge each piece thoroughly in the flour mixture, pressing firmly to coat completely.
Heat 2 inches of vegetable oil in a deep skillet to 350°F (175°C). This is key for how to make crispy chicken fillet.
Carefully place chicken pieces into the hot oil, ensuring not to overcrowd the pan. Fry for 6-8 minutes per side, until golden brown and cooked through (internal temperature of 165°F).
Remove chicken and place on a wire rack set over a baking sheet to drain excess oil.
While chicken drains, prepare the aioli: Mix mayonnaise, fresh dill, lemon juice, and minced garlic.
Lightly butter the cut sides of the brioche buns and toast them in a dry pan until golden.
To assemble your ultimate chicken sandwich build: Spread a generous layer of lemon dill aioli on both the top and bottom buns. Place the crispy dill chicken fillet on the bottom bun. Top with desired lettuce or pickles if desired. Place the top bun on. Serve immediately.
Notes
For an air fryer crispy chicken sandwich, spray the coated chicken lightly with cooking spray and air fry at 400°F (200°F) for 15-18 minutes, flipping halfway.
Using cornstarch in the dredge helps achieve an extra crunchy coating.
The buttermilk marinade tenderizes the meat, making it perfect for dill flavored chicken breast.
