Prep the chicken: Pat the chicken breasts dry with paper towels. If they’re thick on one end, pound gently to an even 3/4–1-inch thickness.
This helps them cook evenly and stay juicy.
Mix the seasoning: In a small bowl, combine salt, pepper, garlic powder, onion powder, smoked paprika, and thyme. Zest half the lemon and stir the zest into the seasoning for a fresh, bright note.
Season lightly: Mist the chicken with olive oil spray on both sides. Sprinkle the seasoning over the chicken, pressing gently so it sticks.
Use about 3/4 of the seasoning on the chicken and reserve the rest for the veggies.
Prep the veggies: Toss your chosen vegetables with a light mist of olive oil spray and the remaining seasoning. Keep pieces similar in size so they cook evenly.
Preheat the air fryer: Set to 375°F (190°C) for 3 minutes. A preheated basket helps develop better browning.
Arrange in the basket: Place the chicken breasts in the center with a little space between them.
Arrange the vegetables around the chicken in a single layer. Avoid overcrowding; work in batches if needed.
Cook: Air fry for 9–12 minutes total, flipping the chicken halfway through. Start checking for doneness at 8 minutes.
The chicken is done when the thickest part reaches 165°F (74°C) on an instant-read thermometer and the juices run clear.
Rest and finish: Transfer chicken to a plate and let it rest for 3–5 minutes. Squeeze fresh lemon over the chicken and veggies. Sprinkle with chopped parsley or chives if using.
Serve: Plate the chicken with a generous scoop of veggies.
Add extra lemon wedges on the side. For a fuller meal that’s still light, serve with a small portion of brown rice, quinoa, or a leafy salad.
