French Onion Hot Dogs

Yeah, now we’re talking about some great hot dogs! Savory and sweet. All-beef dogs smothered in caramelized onions (well worth the 30 or so minutes they take to make), melted Swiss cheese, and topped with thyme. French onion hot dogs are amazingly tasty, and a taste unlike your standard yellow mustard dog. You’ll be very happy devouring one of these.

French Onion Hot DogsI used Vidalia onions for a little sweeter flavor, but any sweet or white onion will do on these French Onion hot dogs. Shallots would be great too, though you’re going to need a good handful or two of them. In a pinch, red onions will work just nicely also.

Also try my Greek hot dogs.

  • Olive oil
  • 2 large sweet onions
  • 1 teaspoon sugar
  • Sea salt
  • Balsamic vinegar
  • 6 all-beef hot dogs
  • 6 hot dog buns
  • 1 cup Swiss cheese shredded
  • Fresh thyme chopped, or dried thyme


  • Heat enough oil to cover the bottom of a large skillet over medium-high heat.
  • Halve the onions and slice thin. Add to skillet and stir to coat in oil. Spread the onions out and let cook for 10 minutes.
  • Stir in the sugar and a few good pinches of salt.
  • Let the onions cook for about 30 minutes, making sure they don't get dry (if they do, add a bit more oil). Do not stir them too much, the idea is get them good and browned and soft.
  • When the onions are just about done add a few splashes of Balsamic vinegar, to taste. Stir.
  • Cook dogs as desired and lightly toast the buns if you wish.
  • Place dogs into buns. Divide the onions and cheese between the dogs. If you want the cheese to get good and melted, throw the dogs under the broiler for a minute.
  • Sprinkle tops with thyme and serve.
