Root Beer Grilled Chicken

Father’s Day grilling calls for something a little memorable, but still simple enough to enjoy without fuss. This Root Beer Grilled Chicken uses a classic upright roasting method with a sweet, savory, nonalcoholic root beer blend that helps the chicken cook up juicy, golden, and full of backyard flavor.

The root beer adds a gentle sweetness and warm spice note, while garlic-infused oil, smoked paprika, thyme, mustard, and black pepper keep the flavor balanced. Choose a gluten-free root beer made with cane sugar and no high-FODMAP add-ins, then pair it with Low-FODMAP chicken broth for a grill-friendly recipe that feels festive and practical.

The result is a tender whole chicken with crisp skin and a subtle smoky-sweet finish. Serve it with grilled vegetables, roasted potatoes, rice, or a simple green salad for a Father’s Day plate that feels generous without being complicated.

Ingredients

For the Chicken

• 1 whole chicken, about 4 to 5 pounds
• 2 tablespoons garlic-infused olive oil
• 1 1/2 teaspoons fine sea salt
• 1 teaspoon smoked paprika
• 1 teaspoon dried thyme
• 1/2 teaspoon ground mustard
• 1/2 teaspoon black pepper
• 1/2 teaspoon dried oregano
• 1/4 teaspoon cayenne pepper, optional
• 1 teaspoon maple syrup

For the Root Beer Can Liquid

• 1/2 cup gluten-free root beer, preferably cane sugar-sweetened
• 1/4 cup Low-FODMAP chicken broth, gluten-free and free from onion or garlic
• 1 tablespoon apple cider vinegar
• 1 teaspoon gluten-free tamari, optional
• 1/4 teaspoon smoked paprika

For Serving

• Fresh parsley or chives, finely chopped
• Lemon wedges
• Grilled zucchini, carrots, potatoes, rice, or a simple green salad

Materials Needed

• Grill with lid or oven
• Clean empty 12-ounce can or vertical chicken roaster
• Small bowl
• Measuring cups and spoons
• Paper towels
• Large plate or tray
• Tongs
• Instant-read meat thermometer
• Cutting board
• Sharp carving knife

How to Make It

1. Prepare the grill. Heat the grill to medium heat, about 350°F to 375°F. Set it up for indirect cooking so the chicken is not directly over the flame or coals.
2. Mix the root beer liquid. In a measuring cup, stir together the gluten-free root beer, Low-FODMAP chicken broth, apple cider vinegar, gluten-free tamari if using, and smoked paprika.
3. Fill the can. Pour the root beer mixture into a clean empty 12-ounce can until it is about half full. You can also pour the liquid into a vertical chicken roaster if you prefer not to cook with a can.
4. Dry the chicken. Remove any giblets from the chicken cavity, then pat the chicken very dry with paper towels. Dry skin helps the outside roast more evenly and crisp better.
5. Make the rub. In a small bowl, combine the garlic-infused olive oil, sea salt, smoked paprika, thyme, ground mustard, black pepper, oregano, cayenne if using, and maple syrup.
6. Season the chicken. Rub the seasoning mixture over the outside of the chicken and lightly inside the cavity. Try to cover the breast, legs, thighs, and wings evenly.
7. Set the chicken upright. Carefully lower the chicken cavity over the prepared can or vertical roaster. The legs and can should help create a stable tripod shape.
8. Cook over indirect heat. Place the chicken on the cooler side of the grill, close the lid, and cook for 1 hour 15 minutes to 1 hour 30 minutes. Rotate only if needed for even browning.
9. Check for doneness. Cook until an instant-read thermometer reaches 165°F in the thickest part of the thigh without touching bone. If needed, continue cooking in 10-minute intervals.
10. Rest before carving. Carefully remove the chicken from the grill and let it rest upright for 10 to 15 minutes. Lift it off the can with care, then carve and serve with herbs and lemon wedges.

Low-FODMAP Notes

Root beer can vary by brand, so check the label before using it in this recipe. For a more Low-FODMAP-friendly option, choose a gluten-free root beer made with cane sugar and avoid products with high-fructose corn syrup, inulin, chicory root fiber, honey, or added fruit juice concentrates.

This recipe also avoids garlic powder, onion powder, wheat-based ingredients, and dairy. Garlic-infused oil gives the rub savory flavor, while Low-FODMAP chicken broth helps balance the sweetness of the root beer.

Recipe Tips

• Use a stable vertical roaster if you are not comfortable cooking with a can.
• Choose a root beer with a clean ingredient list and no high-FODMAP add-ins.
• Pat the chicken very dry before seasoning for better browning.
• Keep the chicken over indirect heat so the outside does not burn before the inside is cooked.
• Use an instant-read thermometer instead of relying only on cooking time.
• Let the chicken rest before carving so the juices settle back into the meat.
