This sweet and savory maple-chili grilled chicken skewer recipe has become my summer grilling staple for both casual weeknight dinners and weekend gatherings with friends. The perfect balance of smoky heat and natural sweetness creates irresistible flavor in every bite.
I first developed this recipe during a summer when I was craving something beyond basic grilled chicken. After several iterations, this combination of maple and chili became the most requested dish at our backyard gatherings.
Ingredients
- Pure maple syrup: Provides natural sweetness and creates beautiful caramelization on the grill
- Olive oil: Helps transfer flavors and prevents sticking
- Apple cider vinegar: Tenderizes the chicken while adding subtle tanginess
- Chili powder: Forms the flavor foundation with its complex pepper blend
- Smoked paprika: Contributes essential smokiness even if you use a gas grill
- Ground cumin: Adds earthy depth that complements the sweetness
- Garlic powder: Infuses savory notes throughout the marinade
- Cayenne pepper: Optional but recommended for those who enjoy a pleasant heat
- Boneless chicken thighs: Preferred for juiciness but breasts work well too
- Bell peppers and red onions: Add color contrast and sweet vegetal flavors
Step-by-Step Instructions
- Create the marinade:
- Whisk all marinade ingredients together in a medium bowl until completely combined. The consistency should be slightly thick with a rich reddish-brown color. Make sure the maple syrup is fully incorporated with no separation.
- Marinate the chicken:
- Place your chicken pieces in a container and pour the marinade over every surface. Gently massage the marinade into the meat to ensure complete coverage. Cover and refrigerate for at least one hour to allow the flavors to penetrate. The longer you marinate the more pronounced the flavor will be.
- Prepare for grilling:
- If using wooden skewers soak them thoroughly in water for at least 30 minutes. Preheat your grill to medium-high heat around 375-400°F. You want it hot enough to get good caramelization but not so hot that the sugars burn before the chicken cooks through.
- Assemble the skewers:
- Thread the marinated chicken pieces alternating with colorful bell peppers and red onion chunks. Leave small spaces between each piece to ensure even cooking. Discard any remaining marinade that contacted raw chicken.
- Grill to perfection:
- Place skewers on oiled grill grates with space between each. Grill for 5-6 minutes per side turning just once to develop beautiful grill marks. The chicken should reach an internal temperature of 165°F and have a glossy caramelized exterior with slightly charred edges.
- Rest before serving:
- Transfer skewers to a clean platter and allow them to rest for 2-3 minutes. This crucial step allows juices to redistribute throughout the meat resulting in more tender flavorful chicken.

The smoked paprika is my secret ingredient here. I discovered its transformative power during a cooking class in Spain where the instructor showed us how it can add incredible depth even to the simplest dishes. Now I keep several varieties in my pantry at all times.
Make-Ahead Options
While best grilled fresh, you can prepare these skewers in advance for easy entertaining. Marinate the chicken for up to 8 hours in the refrigerator, then assemble skewers and keep them covered until about 30 minutes before grilling. Let them come to room temperature slightly for more even cooking.
Vegetarian Adaptation
This marinade works beautifully for plant-based alternatives too. Try using extra-firm tofu cubes, pressed and dried thoroughly before marinating, or substitute with portobello mushroom chunks. Increase vegetables like zucchini, yellow squash, or cherry tomatoes for colorful vegetarian skewers with the same delicious flavor profile.
Serving Suggestions
These flavorful skewers pair wonderfully with simple sides that complement without competing. Serve alongside fluffy coconut rice, a bright cucumber salad, or grilled corn on the cob with lime butter. For a complete meal, add warm pita bread and a bowl of tzatziki or creamy avocado sauce for dipping.
Regional Variations
This recipe draws inspiration from several grilling traditions. The maple syrup nods to New England flavors, while the chili and smoked paprika reflect Southwestern influences. In Latin American countries, similar skewers might use honey instead of maple and incorporate additional citrus elements. Make it your own by adjusting the spice blend to reflect your favorite regional flavors.

Common Questions
- → How long should I marinate the chicken?
Marinate the chicken for at least 1 hour to allow the flavors to penetrate, but you can marinate for up to 8 hours for more intense flavor. Don't exceed 8 hours as the acidity in the marinade can start to break down the chicken texture.
- → Can I make these skewers in the oven instead of a grill?
Yes! You can broil these skewers in the oven. Place them on a lined baking sheet and broil on high for 5-6 minutes per side, or until the chicken reaches an internal temperature of 165°F (74°C). You won't get the same smoky flavor as grilling, but they'll still be delicious.
- → What's the best way to prevent wooden skewers from burning?
Soak wooden skewers in water for at least 30 minutes (or up to several hours) before threading on your ingredients. This prevents them from burning during grilling. Alternatively, you can use metal skewers which don't require soaking.
- → Can I substitute the maple syrup with something else?
Yes, honey makes an excellent substitute for maple syrup in this marinade. Agave nectar or brown sugar dissolved in a bit of water would also work, though each will provide slightly different flavor notes.
- → How can I tell when the chicken is fully cooked?
Chicken is fully cooked when it reaches an internal temperature of 165°F (74°C). If you don't have a meat thermometer, cut into the largest piece - properly cooked chicken should be opaque all the way through with no pink remaining.
- → What can I serve with these chicken skewers?
These skewers pair beautifully with grilled corn on the cob, couscous or grain salads, cucumber-yogurt sauce, or a simple green salad. For a complete meal, consider serving with rice pilaf or warmed pita bread with hummus.
