In a medium mixing bowl, whisk together soy sauce, lemon zest, lemon juice, brown sugar, 2 tablespoons olive oil, minced garlic, and smoked paprika to make the marinade.
Place chicken in the marinade and cover (or place chicken and marinade in a Ziploc bag). Refrigerate for at least 30 minutes, even better if you can marinate overnight.
Just before assembling the foil packets, toss together baby potatoes, green beans, 2 tablespoons olive oil, 1 tablespoon of chopped parsley, and salt/pepper to taste.
Tear off four large (18”x18”) sheets of aluminum foil. Fold in half once to form a double layer rectangle.
Place 1⁄4 of the veggie mixture in the center of the foil. Place one chicken breast over the top of the vegetables. Fold in each side to the center and then fold in the top and bottom to form a secure packet. Repeat for the remaining ingredients to form four foil packets.
Cook over grill or campfire at 400°F for about 25-30 minutes or until potatoes are fork tender and the chicken registers 165°F internal temperature.
Season with salt, pepper, and a fresh sprinkle of parsley, if desired.
Leave a little room in the foil packets for the steam to escape.
You are essentially steaming the food in your foil packet. For this reason, the chicken doesn’t get a lot of color or char like it would over an open fire. Be careful not to overcook the chicken or it will dry out. A longer marination time (i.e., overnight) will also make for moister chicken.
You can add any of your favorite vegetables to this foil packet. The veggies cook in the juices from the chicken and take on the sweet and salty flavors of the marinade.
I would recommend mixing up the marinade at home and tossing the chicken and marinade into a gallon size Ziploc before heading out on your camping trip. This will give the chicken ample time to marinade AND you won’t have to carry the ingredients for the marinade on your trip!
