Preheat the oven to 400 degrees.

Add half of the French Onion soup mix to the ground beef and gently mix. Form the beef into four evenly sized patties; set aside.

Slice the carrots, potatoes and onions into thin slices. Drizzle the olive oil over the veggies and add the remaining French Onion soup mix. Toss to combine.

Place one patty in the center of each large sheet of tin foil.

Add an equal amount of potato, carrot and onion to each foil packet.

Fold the long sides of the tin foil sheets up and over the contents, and roll closed to secure.

Roll up the remaining sides of each piece of tin foil to form a secure packet.

Bake for 40 minutes.

Carefully open the foil packets and serve.
