Pick out some potatoes. No more than 1 per serving you expect to make. If you make a lot of baked potatoes, this is your opportunity to get rid of the funky-shaped ones.
Cut them up into bite sized pieces. I prefer to keep the skins on them, but you can peel them if you'd like.
Add some olive oil, just enough to coat the potatoes with. Then add your other seasonings, whatever you want. You can add some diced onions, mushrooms, whatever floats your boat!
Mix the potatoes and other ingredients in a bowl. Make sure all pieces are coated with the oil and you have the seasonings mixed thoroughly.
You can use a spoon to mix but its more fun tossing them around like I do. Keep a towel handy to clean up. :)
Lay out squares of your parchment paper. One per serving you want to have.
Spoon out the potatoes, one serving on the paper.
Take all 4 corners and pinch them together with one hand, then bring the "new" corners caused by the folds up as well.
Twist the top tightly around, so you now have your potatoes wrapped up in a shape that's kind of like a Hershey's Kiss.
Put the rest of your potatoes together the same way.
On the grill put the papers away from the direct heat and fire. You can do this with a gas grill, charcoal (like mine), a smoker or heck even in the oven if you can keep the paper away from flame.
If you do them in an oven use a cookie sheet and put them on a lower rack if you have overhead heat. I'd cook at 350 for 45 minutes. The rest of this guide shows the results from the grill.
On the grill at 250 F these will take 1.5 hours max. If you have a higher heat going adjust times accordingly. I always prefer slower cooking. You can see the paper changes color but doesn't burn.
Inside the paper the potatoes are thoroughly cooked and delicious! I serve these still in the paper and everyone loves the presentation. A really interesting and different way to serve them!
