1-First Step: Mix the marinade In a medium bowl, combine the Greek yogurt, extra-virgin olive oil, paprika, cumin, cinnamon, red pepper flakes, lemon zest, lemon juice, salt, black pepper, and minced garlic. Stir until the mixture looks smooth and well blended. This is the flavor base for your grilled kabobs, so take a moment to make sure the spices are evenly mixed through the yogurt. If you want a stronger garlic flavor, you can double the garlic here. That is an easy trick for people who love bold middle eastern kabobs.

2-Second Step: Prepare the chicken Trim any excess fat from the chicken thighs, then cut them into 1 1/2-inch pieces. Keeping the pieces about the same size helps them cook at the same speed, which is important for all grilled chicken kabobs. If some pieces are much smaller than others, the smaller ones can dry out before the bigger ones are done. Chicken thighs are the best choice here because they stay juicy over high heat. That is one of the reasons these are such dependable summer chicken kabob recipes.

3-Third Step: Skewer the kabobs Thread the chicken onto skewers, alternating with the red onion chunks. Leave a little room between pieces so the heat can move around each one. If you are using wooden skewers, soak them in water for 30 minutes first so they do not burn on the grill. For a quicker version, you can skip the skewers and grill the chicken pieces and onion wedges directly. That trick works well when you need easy dinner ideas and do not have time to assemble every kabob.

4-Fourth Step: Marinate and chill Place the kabobs on a foil-lined baking sheet and brush them with the marinade. Cover the tray and refrigerate for at least 8 hours, or overnight if possible. The long marinating time helps the chicken absorb the lemon, garlic, and spice flavors, which is what makes these grilled chicken kabobs taste so good. For the best flavor, do not rush the marinating step. Eight hours or more gives you more tender, more flavorful kabobs.

5-Fifth Step: Preheat and prep the grill When you are ready to cook, preheat the grill to medium-high heat. That usually means about 375 to 400°F. Brush or wipe the grates with vegetable oil to help prevent sticking. This small step makes a big difference, especially with yogurt-based marinades. If you are cooking outdoors for a crowd, this is one of the most practical kabob recipes because the grill does most of the work while you prep sides and drinks.

6-Sixth Step: Grill the kabobs Place the kabobs on the hot grill and cook them for 13 to 15 minutes, turning occasionally so they brown on all sides. You want the chicken to look golden and lightly charred, while the onion turns soft and a little caramelized. The internal temperature of the chicken should reach 165°F. Try not to move the kabobs too much at first. Letting them sit on the grate for a minute or two helps you get those nice grill marks that make summer kabobs look as good as they taste.

7-Seventh Step: Rest and serve Once the chicken reaches 165°F, take the kabobs off the grill and let them rest for a few minutes. This helps the juices settle back into the meat. Then serve them warm with rice, pita, chopped salad, or a simple dip. If you want to round out the meal with a dessert, try a chilled treat or a bright citrus sweet like homemade lemon curd for a fresh finish.
