In my opinion, this sauce is the BEST topping for hot dogs. Maybe I’m biased, having grown up in New York where this sauce is extremely popular, but I LOVE this sauce. After playing with several recipes, I have decided this is my favorite among them.
Start by thinly slicing six yellow onions. White would work just as well, or even vidalia. I always have plain old yellow onions on hand though.
While you are slicing the onions, get a skillet heating over medium heat. Once hot, two turns of extra virgin olive oil go in to heat.
Saute the onions, adding in six to eight cloves of finely minced garlic. Salt well to start the onions sweating.
Once the onions have started to soften, add in two-thirds cup of your favorite ketchup, one tablespoon red chili flakes and one tablespoon of smoked paprika. Depending on taste, adjust the amount of red chili flakes. We are not shy about a little heat!
Turn heat down to low, and simmer for about fifteen minutes. Add in a half of a cup of good old-fashioned white vinegar. Simmer for an additional forty-five minutes.
If needed, add salt to taste. Serve over your favorite hot dog! If I may make one more suggestion? Spicy yellow mustard, then the red onion sauce is a perfect match!
By the way, my husband loved this sauce so much he declared it would be good “on just about anything”!
