French Onion Baked Potato (Can be made Vegan)

Dig that title.  It's like eating onion soup and instead of croutons, you've got a potato.  Next time at the end of the cooking time I might try to open up the packet, put some Swiss or Gruyere cheese on top and let it melt!  I was so full from one half of this potato, I had the other half for lunch the next day!  You will need:
Idaho baking potatoes
1/2 small vidalia onion per potato
Beef or Vegetable soup base
tabs of butter or vegan margarine
2 sheets of foil per potato
1.)  Preheat your oven to 375 degrees.  (This can also be cooked on the grill).  Wash and scrub your potatoes.  Pat them dry. 
2.)  Cut slices in the potatoes about 1 inch apart.  Being careful not to cut all the way through the potato.  Place each potato onto the sheets of foil.
3.)   Slice the onion into moons.  Insert the moons in between the slices.  Put some additional slices of onions on top.  
4.)  Top each potato with a few tabs of butter/margarine.  Gather the foil to the top and crimp.
5.)  Place the potatoes on a cookie sheet and bake until the potatoes are done.  This will depend on the size of your potatoes.  Check for doneness by inserting a knife in the top of the potato.  Being careful not to go through the bottom of the foil.  (You don't want to lose the juices on the bottom!)
6.)  Carefully remove the potatoes from their foil packets and drizzle the sauce in the bottom of the packet over the potatoes.

Oh and excuse the plated picture,  my husband had at it before I remembered to take a picture!
