In a medium bowl, combine 2 tablespoons olive oil, lemon juice, lemon zest, paprika, oregano, basil, thyme, garlic, shallot, 1 1/4 teaspoons salt and 1 1/4 teaspoons pepper.
Stir in chicken until well combined; marinate for at least 2 hours to overnight, turning occasionally. Drain the chicken from the marinade.
Thread chicken onto skewers. Brush with remaining 2 tablespoons olive oil; season with salt and pepper, to taste.
Preheat grill to medium heat.
Add skewers to grill, and cook, turning occasionally, until the chicken is completely cooked through, reaching an internal temperature of 165 degrees F, about 10 minutes.
Serve immediately.
Notes
An outdoor grill is not necessary. Too cold to grill outside? A cast iron grill pan can be used to get those favorited grill marks and charred flavor.
Use freshly squeezed lemon juice. While bottled lemon juice can work in a pinch, freshly squeezed is ideal here for its vibrant, stronger flavors.
Mix it up. Thread bell peppers, zucchini, tomatoes or mushrooms to the kabobs for added veggies.
Work in batches. An overcrowded grill or pan can lead to uneven cooking and poor browning. Work in batches to maintain high heat for a good sear and crispy crust on each chicken skewer.
Use an instant-read thermometer for the most accurate results. The internal temperature should reach 165°F.
Let your meat rest. Let your chicken kabob rest for at least 5 minutes prior to serving, allowing the juices to redistribute – this will allow for maximum flavor and juiciness.
Reheat in the oven. Leftover chicken can be rubbery when reheated. For best results with leftovers, reheat in the oven at 350°F, covered in aluminum foil until warmed through.
