Grilled Onions and Potatoes

Grilled Onions and Potatoes


"My family loves these tasty potatoes. There are never leftovers. Once the potatoes are all tucked in their foil packets, they can wait overnight to be grilled the next day. Great for camping. Check foil packets at 15 and 30 minutes to ensure they are not burning. May require a few more minutes to ensure all is cooked through."

  2. Stir mayonnaise, Parmesan cheese, garlic, red pepper flakes, paprika, salt, and pepper together in a large bowl. Add potatoes and onion; stir to coat completely.

Delicious! We thinly sliced the potatos, mixed all together, then baked @ 400 degrees in the oven for 1 hour in a covered pan.

I followed the recipe exactly. They were tasty, but not a recipe I would use often.

I don't think anyone is ever going to find, let alone rate this recipe so I am going to do it myself. 2 thumbs up Ally :-)

This recipe is delicious as written. The only change I made, I use smoked paprika for that added "grilled" flavor. After I flip them on the grill, I poke holes in the foil to let out the steam...
