Prepare Chicken: Slice the chicken breasts into thin, even strips. If the chicken is slightly frozen, it will be easier to slice.
Make Marinade: In a bowl, combine soy sauce, Worcestershire sauce, honey, apple cider vinegar, minced garlic, onion powder, black pepper, and cayenne pepper.
Marinate Chicken: Place the chicken strips in the marinade, ensuring they are fully submerged. Marinate in the refrigerator for at least 2 hours, preferably overnight.
Oven Preparation: Preheat your oven to 175°F (80°C). Line a baking sheet with parchment paper and place a wire rack on top.
Arrange Chicken: Remove the chicken from the marinade and pat dry. Lay the strips on the wire rack, ensuring they don't touch each other.
Bake: Bake for 3 to 4 hours, or until the jerky is dry and firm yet still pliable.
Cool and Store: Let the chicken jerky cool completely before storing in an airtight container.
