Grilled Caprese Chicken Foil Packs

Boneless chicken breasts butterflied and stuffed with pesto, fresh mozzarella, and tomato, then grilled in foil packs with baby potatoes. The chicken cooks through while potatoes become tender, all seasoned with Italian herbs and finished with fresh basil.

- 1 ½ lbs little potatoes
- (to taste) extra virgin olive oil

- 8
Season chicken with salt, pepper, and Italian seasoning, then drizzle with olive oil.
- 9
Bring the two long ends of foil up to meet and fold down a few times, leaving air to circulate. Bring up the sides inward so packs will not leak.
- 10

Remove packs from grill and carefully open as they will be hot.

Tips
Do not slice chicken all the way through to keep the breast intact for stuffing.
Leave foil loosely sealed to allow air circulation for even cooking.
Use a meat thermometer to ensure chicken reaches 165 degrees F for food safety.
Good to Know
Refrigerate leftovers in airtight container for up to 3 days. Reheat gently in oven to avoid drying chicken.
Prepare foil packs up to 4 hours in advance. Store in cooler until ready to grill.
Serve immediately after opening foil packs while hot. Garnish with fresh basil at table.
Common Mistakes
Do not seal foil tightly to avoid steaming instead of grilling.
Do not slice chicken completely through; keep skin and bottom intact for stuffing.
Do not skip checking chicken internal temperature to avoid undercooked meat.
