Mix the ground beef, ketchup, Worcestershire sauce, onion powder, garlic powder, salt, paprika, pepper and water in a large bowl until well combined and set aside.
Mix the potatoes, carrots, olive oil, garlic powder, salt, and pepper in a large bowl until well combined.
Lay out (6) 18x12 sheets of foil (use heavy-duty foil if you can) and spray with nonstick cooking spray.
Add 1/6th of the potato and carrot mixture into the center of each foil packet.
Divide the meat mixture into 6 patties and place one on top of the vegetables.
Evenly distribute the onion slices on top of the burgers.
Last, add 1 tablespoon of butter on top of each one.
Crimp and secure each packet well so no air can escape.
Preheat the grill to 400°F (medium-low to low heat). I like to add an oven thermometer to the grill so I can make sure of the temperature.
Once at 400°F, add the packets to the grill and shut the top. Cook until the burgers reach 160°F and the vegetables are tender, about 30-40 minutes.
