Cut chicken breasts into 1-inch cubes, ensuring uniform sizing for even cooking. Place cubed chicken in a large mixing bowl, ready for the marinade magic that transforms ordinary poultry into something extraordinary.
Combine smoked paprika, garlic powder, onion powder, and cayenne pepper in a separate small bowl. Whisk in olive oil, balsamic vinegar, Worcestershire sauce, brown sugar, salt, and black pepper until smooth and fully integrated.
Pour the marinade over chicken cubes and toss thoroughly to coat every piece. Let sit for 8-10 minutes while you prepare bell peppers and red onion chunks, allowing flavors to penetrate the protein deeply.
Thread marinated chicken alternately with bell pepper chunks and red onion onto your soaked wooden skewers. This juicy smoky tailgate grilled chicken skewers recipe comes alive when you create that visual appeal with colorful vegetable distribution throughout each skewer.
Preheat grill to medium-high heat (400°F). Brush grates with oil to prevent sticking and ensure beautiful char marks that signal proper cooking.
Place skewers directly on hot grill grates and cook for 6 minutes without moving them. This creates those coveted caramelized edges while keeping insides tender and juicy.
Flip skewers carefully and grill for another 5-6 minutes until chicken reaches 165°F internal temperature. An instant-read thermometer removes all guesswork about doneness, guaranteeing perfectly cooked poultry every single time.
