1. Prepare the Chicken: Start by patting the boneless, skinless chicken breasts dry with paper towels. This helps the seasoning adhere better and promotes a crispier exterior. Cut the chicken into 1-inch bite-sized pieces. Aim for uniform sizes so they cook evenly.

2. Season the Chicken: In a medium bowl, combine the cut chicken pieces with 1 tablespoon of olive oil, garlic powder, dried thyme, crushed dried rosemary, dried dill, salt, and black pepper. Toss everything together thoroughly until all the chicken pieces are well coated with the seasoning mixture.

3. Prepare the Broccoli: Wash the fresh broccoli florets and pat them dry. In a separate bowl, toss the broccoli florets with the remaining 1 tablespoon of olive oil. You can add a pinch of salt and pepper to the broccoli if desired, but the chicken seasoning will also flavor the overall dish.

4. Preheat the Air Fryer: If your air fryer requires preheating, set it to 375 F (190 C) and let it preheat for 3-5 minutes. This helps ensure even cooking and a crispy texture.

5. Arrange in the Air Fryer: Place the seasoned chicken bites in a single layer in the air fryer basket. Do not overcrowd the basket; cook in batches if necessary to allow air to circulate properly, ensuring the chicken cooks evenly and gets crispy. Add the broccoli florets alongside the chicken, also in a single layer if possible.

6. Air Fry to Perfection: Air fry the chicken and broccoli for 15-18 minutes, shaking the basket halfway through the cooking time (around the 8-minute mark). This ensures both the chicken and broccoli cook evenly and become golden brown. The chicken should be cooked through with an internal temperature of 165 F (74 C), and the broccoli should be tender-crisp.

7. Check for Doneness: Before serving, ensure the chicken is fully cooked by checking the internal temperature with a meat thermometer. The broccoli should be tender but still have a slight bite.

8. Serve Immediately: Transfer the cooked chicken bites and broccoli to a serving platter and enjoy them hot.
