Rosemary Butter Grilled Chicken with Foil-Packet Vegetables
Charred chicken pieces and summer vegetables infused with rosemary garlic butter, cooked via indirect grill heat. The foil packet steams vegetables while chicken develops a golden crust from basting. Perfect for casual summer entertaining when you want hands-off cooking with bold herb flavor. This version uses a drip pan setup for temperature control and allows the vegetables to soften while the chicken skin crisps.
Ingredients
- ½ cup butter, melted
- 1 tablespoon garlic, fresh finely chopped
- 1 tablespoon rosemary, fresh chopped
- 3 cup zucchini and/or yellow summer squash, cut into 1-inch pieces
- 2 medium onion, cut into eighths
- 1 cup eggplant, cut into 1-inch cubes (about 1 small)
- 1 3-4 pound chicken, whole frying chicken cut into 8 pieces skinned
Instructions
- 1
Heat one side of grill to medium (gas) or until coals turn ash white (charcoal). Push coals to one side; position drip pan opposite heat.
- 2
Whisk butter, garlic, and rosemary together.
- 3
Combine zucchini, onions, and eggplant in center of 18-inch aluminum foil square. Drizzle with half the butter mixture. Fold foil edges to center and seal tightly.
- 4
Place chicken skin-side up over drip pan. Grill 10 minutes.
- 5
Brush chicken with butter mixture and flip. Move foil packet directly over heat.
- 6
Continue grilling, turning chicken and brushing with butter every few minutes, until internal temperature reaches 165F and juices run clear when pierced. Vegetables should be crisply tender.
- 7
Serve chicken with foil packet vegetables.
Tips
Seal foil packet tightly to trap steam; crimp edges twice for security. Packet integrity prevents butter from escaping and ensures even vegetable cooking.
Brush chicken every 7-10 minutes with herb butter to build flavor layers and prevent drying. Reserve some uncooked mixture if handling raw chicken.
Use a meat thermometer inserted into thickest thigh (without touching bone) for foolproof doneness at 165F. Visual cues (clear juices) are less reliable.
Good to Know
Refrigerate cooked chicken and vegetables in airtight container up to 3 days. Do not store assembled foil packets uncooked beyond 4 hours.
Prep vegetables and measure butter mixture up to 8 hours ahead. Assemble foil packet 2 hours before grilling. Do not store chicken raw in foil packet.
Serve immediately while chicken is hot and vegetables retain slight firmness. Pair with crusty bread, salad, or grilled potato wedges.
Common Mistakes
Do not seal foil packet too loosely to avoid losing butter and creating uneven cooking.
Do not skip the drip pan setup to avoid flare-ups from butter dripping onto coals.
Do not grill chicken skin-side down initially if using charcoal without drip pan directly underneath.

FAQ
Can I use bone-in chicken skin-on instead?
Yes, but extend initial grill time to 12-15 minutes skin-side down before flipping. Skin adds fat that bastes the meat; aim for 160F internal temp since bone-in takes longer. Moisture will render during cooking.
What if my foil packet tears during grilling?
Wrap a second piece of foil around the damaged section immediately. Prevent tears by using heavy-duty foil and avoiding sharp vegetable edges. If juices spill, vegetables may cook faster; monitor closely and move packet away from direct heat if needed.
Can I prepare the foil packet ahead and freeze it?
Assemble uncooked packets and freeze up to 3 months. Thaw completely in refrigerator before grilling; do not grill from frozen as vegetables won't cook through evenly. Grilling time may increase 5-10 minutes from thawed state.
