Roughly chop the onion, potatoes, and carrots into bite-sized pieces.
You’ll need 3 large pieces of foil per foil packet. Layer potatoes, carrots, and onions onto the first layer of foil. (For the first layer only, a piece of parchment paper can also be used if you don't want food to cook directly on aluminum foil.)
Use a fork to drop bite-sized clumps of ground turkey on top of the veggies. No need to roll the turkey into meatballs. Just take a spoon or fork and scoop the meat right onto the foil.
Drizzle your favorite BBQ sauce on top, followed by about 1 tablespoon of butter (per packet) cut into smaller pieces.
To fold the packets, bring the two longest edges towards each other and roll them together to create a seal. Then, fold in the sides. Rip off another piece of foil. Place the packet seam side down, and repeat the same folding process. Do this one more time for a total of 3 pieces of foil per packet. (If using parchment paper for the first layer, still use 3 pieces of foil on top of that.)
Place the packets on top of campfire coals (not flames). Cook for 40 minutes, flipping the packets every 10 minutes until the veggies are tender and the turkey is fully cooked.*
Once done, top the meal with more BBQ sauce, salt, pepper, and sour cream if desired. Enjoy!
Notes
*Cooking times will vary based on how big or small you chopped your ingredients, how big you made your foil packets, and how hot your coals are. If you notice that the coals have cooled, simply bring in some new ones to heat things back up until you hear a faint sizzle sound. You can always take a packet off of the coals and carefully open it up to check on doneness. If it needs more time, simply fold it back up and let it cook longer.
