Place the chicken breasts on a plate and pat them dry with paper towels. Poke each breast 3 to 4 times with a fork.
In a small bowl, mix the lemon pepper, garlic powder, salt, and celery seeds.
Sprinkle the seasoning mix evenly over both sides of the chicken. Pat gently to help it stick.
Place the seasoned chicken in a 9x13-inch baking dish and cover with plastic wrap. Refrigerate for at least 2 hours or up to overnight.
Preheat your grill to 400°F. If using a charcoal grill like a Big Green Egg, let it heat for an extra 5 to 7 minutes after reaching temperature for a better sear.
Place the chicken in the center of the grill. Cook for 6 minutes per side, or until the internal temperature reaches 165°F.
If the chicken breasts are uneven in thickness, trim or butterfly them for more even cooking. You can also place thicker pieces on earlier to give them a head start.
Remove the chicken from the grill and let it rest for 5 to 6 minutes.
Serve and enjoy!

Air Fryer: Preheat to 350°F. Reheat sliced or whole pieces for 4-6 minutes, flipping halfway through. Mist with a bit of water or broth if needed.
Microwave: Place slices on a microwave-safe plate. Cover with a damp paper towel and heat in 30-second bursts until warmed through.

💡 TIPS FOR BEST RESULTS
Do not marinate the chicken longer than overnight, or it may become tough.
Let the grill heat fully before adding the chicken for better grill marks.
Trim uneven breasts or butterfly them to ensure even cooking.
