Instructions
Cut a large piece of heavy duty aluminum foil.
Place the shiny side up and fold the foil up to make a large casserole shaped "boat."
Spread the butter on the foil.
Lay the onion slices on the foil in a single layer.
Wash and slice the potatoes in ⅛" slices.
Place the sliced potatoes on top of the onions.
Pour the milk into the foil boat, over the potatoes and onions.
Sprinkle with salt and pepper.
Fold each side of the foil together and seal the edges by folding the foil over itself, making a sealed package for grilling.
Place the package on a medium hot grill (about 350F degrees), with onion side down.
Bake the package for about 40 minutes with the onion side down. You want the onions to caramelize.
Turn the package over and continue baking for about 20 more minutes, until the potatoes are tender and the juice is bubbly.
Remove the package of potatoes from the grill and let rest 5 minutes before serving.
Notes
Note: If you don't have a waxy variety of potato, you can use any potato and add a tablespoon of flour or gluten free flour to the milk to help it thicken. Another option is to mix in a tablespoon of mashed potato flakes. They are a terrific thickener. Be sure to mix the thickener in the milk before you pour it over the potatoes.
