This sweet and spicy Fireball Chicken delivers an irresistible combination of cinnamon whisky, tangy ketchup, and spicy jalapeño jelly that transforms ordinary chicken breasts into a memorable meal. The sauce caramelizes beautifully on the grill, creating sticky, flavorful chicken that balances heat with sweetness.
I first made this recipe for a summer barbecue with friends who love bold flavors. The combination of Fireball whisky and jalapeño jelly raised some eyebrows at first, but it quickly became our go-to grilling recipe for gatherings where we want to surprise guests with something unexpected.
Ingredients
- Boneless skinless chicken breasts: Essential protein that absorbs the flavorful marinade beautifully; look for even-sized pieces to ensure consistent cooking
- Ketchup: Creates the tomato base for the sauce; use a quality brand for best flavor
- Jalapeño pepper jelly: Provides both sweetness and heat; try homemade for extra flavor points
- Fireball cinnamon whisky: The star ingredient that gives this dish its distinctive warm cinnamon kick
- Unsalted butter: Adds richness and helps the sauce cling to the chicken
- Light brown sugar: Enhances the caramelization and balances the heat
- Apple cider vinegar: Provides necessary acidity to cut through the sweetness
- Spices including paprika, garlic powder, onion powder, cinnamon: Creates depth of flavor without overwhelming the signature Fireball taste
Step-by-Step Instructions
- Prepare the Chicken:
- Place chicken breasts in a 9x13 baking dish, ensuring they are pounded to an even thickness of about 3/4 inch. This uniform thickness guarantees the chicken will cook evenly on the grill without drying out before the center is done.
- Create the Signature Sauce:
- Combine all sauce ingredients in a 2-quart saucepan over medium heat. Whisk together ketchup, jalapeño jelly, Fireball whisky, butter, brown sugar, vinegar, and all spices until completely incorporated. The melting butter will help emulsify the sauce, creating a smooth consistency.
- Simmer to Perfection:
- Bring the mixture to a boil before reducing heat to low. Allow the sauce to simmer for exactly 5 minutes, stirring occasionally. The sauce will thicken slightly but remain pourable enough to coat the chicken properly. Remove from heat and let cool for 5 minutes to allow flavors to meld together.
- Marinate the Chicken:
- Reserve 1/2 cup of sauce, setting it aside for basting during grilling. Pour remaining sauce over chicken breasts, ensuring each piece is completely coated. Cover the dish and refrigerate for at least 2 hours, ideally overnight to allow the flavors to penetrate the meat fully.
- Grill with Precision:
- Preheat your gas grill to exactly 425°F. Place marinated chicken on clean, oiled grates, cooking the first side for 7 to 9 minutes depending on thickness. Flip once and cook the second side for another 7 to 9 minutes until internal temperature reaches 165°F.
- Glaze for Final Flavor Boost:
- Brush reserved sauce onto each side of the chicken during the final minutes of cooking, allowing it to caramelize slightly without burning. Cook each side an additional minute after glazing to set the sauce and create that sticky, delicious exterior.
- Rest Before Serving:
- Transfer finished chicken to a serving platter and allow to rest for 5 full minutes. This crucial step lets the juices redistribute throughout the meat, ensuring moist, tender chicken with every bite.

You Must Know
The jalapeño pepper jelly is truly the unsung hero of this recipe. I discovered this ingredient years ago at a local farmers’ market and now keep jars of it in my pantry for recipes exactly like this one. The way it combines with the cinnamon notes from the Fireball creates a complexity that tastes like you spent hours developing the flavors.
Make-Ahead Options
This chicken shines when marinated overnight, allowing the flavors to fully penetrate the meat. You can prepare the sauce up to three days ahead and keep it refrigerated in an airtight container. For busy weeknights, I often prepare everything the night before so I can simply fire up the grill when I get home from work.
Serving Suggestions
Fireball Chicken pairs beautifully with simple sides that complement without competing with its bold flavors. A classic coleslaw with a vinegar-based dressing cuts through the richness, while corn on the cob echoes the sweetness in the sauce. For a complete meal, consider serving with cilantro lime rice, which provides a fresh, citrusy counterpoint to the spicy-sweet chicken.

Adjusting the Heat Level
The beauty of this recipe lies in its adaptability to different spice preferences. For a milder version, reduce the jalapeño jelly to 1/4 cup and increase the brown sugar slightly. If you prefer more heat, add a teaspoon of your favorite hot sauce or a pinch of cayenne pepper to the sauce mixture. The cinnamon notes from the Fireball whisky will still shine through regardless of how you adjust the spice level.
