Gather your ingredients and turn your grill on high heat.
Wash the potatoes and chop them into cubes.
When you are finished, wash the potatoes once more since they have a habit of being dirty. :(
In a separate container, add 1 tbsp of olive oil. I usually make sure it has a lid so everything can be mixed together.
Add 4 tbsp of French onion soup to the oil. You can also add chicken, veggie, or beef stock. This really helps make the potatoes tender and delicious.
Add 1 tsp of garlic salt to the mixture.
Add 1 tbsp of minced onion flakes to the mixture.
Add 1 tbsp of rosemary to the mixture.
Add 1 tsp of minced garlic. (I know, it does have a lot of garlic, but it tastes great)
Mix everything together
Add the freshly washed potatoes to the mixture.
The potatoes added into the mixture.
Slice half an onion and add it to the mixture.
Put the lid on the tip and shake everything together.
I usually flip the container upside down to make sure it mixes evenly. If you do this, make sure the lid is sturdy.
Now, grab a large sheet of tin foil. You want to make sure the potatoes will all for. Spray the foil with Nonstick spray. You can also use oil if you like.
Take the potato mixture and evenly distribute on the tin foil.
I sprinkled additional rosemary on top because I love the taste of rosemary. :)
Fold the tin foil over so it makes a nice little container for the potatoes.
Make sure it's completely folded over and has no visible openings.
Make sure the grill is cleaned off and add the potatoes to the grill to cook. Turn the heat down to medium.
After 10 minutes, stir the potatoes and be careful not to burn yourself . After you are finished, cover it up and continue doing this every 10 minutes for 30 more mins or until the potatoes are soft.
When they are finished, take them off the grill and let them sit for 5 minutes.
Serve with your favorite entree and enjoy!
