Uncle Bill’s Onion Soup Mix Potatoes

Picture of cooked onion soup mix potatoes in foil


This is a recipe my mom always called “Uncle Bill’s Potatoes”. I don’t have an uncle Bill, so don’t worry about the nomenclature if you want to call them that too. Some other folks will call them onion soup mix potatoes, or foil pack onion potatoes. Whatever you call them, they are Dan Good, super easy, and Dan-O’s Seasoning takes them to the next level! 

There are 4 simple ingredients here: butter, potatoes, Dan-O’s Seasoning, and a packet of onion soup mix. What I do is slice my potatoes pretty thin, then add them to a bowl. Mix in the dry ingredients and a half stick of melted butter, and that’s it! Wrap these bad boys in foil, and then you can bake them, throw them on the grill, or cook them on a campfire. Which you should always have Dan-O’s when you’re camping, duh…. 

I’ve done this onion soup mix potatoes recipe with red potatoes, gold potatoes, and your standard russet potatoes. I’ll be the first to tell you, they’re all delicious! The main flavor savers, however, are as follows: use the Dan-O’s Seasoning… quite a bit of it. And cook these on a charcoal grill for the best flavor.

And there you have it! Rich, tender, oniony and buttery potatoes, with the best herb and spice blend known to man. A little smoky taste from the coals, and the other good food items you’re eating these with. Now your next job is to pass this on to your nephews and nieces… because Uncle Bill (whoever he was) made some mean potatoes!


  • 2 large potatoes
  • 1 pack of dry onion soup mix
