This homemade onion sauce is everything! It is the perfect topping to any hot dog that you are grilling up this summer. You can even serve it as a side to steaks, chicken or hamburgers. I mean the flavor just rocks! And this homemade version is SO much better for you than those store bought bottle that have preservatives and added colors.

The best tip I could give you for this recipe is to make sure that your onions are caramelized before adding in the other ingredients. It takes a little bit, so be patient, because it is totally worth it!

Get them nice and caramelized!

Add in the spiced ketchup mixture.

  • pinch ground nutmeg
  • 1/8 tsp chili powder

In a medium sauce pan, heat vegetable oil over medium heat.
Add in the sliced onions and cook, stirring occasionally, until the onions start to turn golden brown. This can take up to 10 minutes.
Meanwhile, in a small mixing bowl, add ketchup, cinnamon, nutmeg, chili powder, garlic powder, tabasco and salt and whisk together to combine.
Pour the ketchup mixture and the water into the sautéed onions and stir to combine. Bring to a boil and reduce the heat to a simmer and let cook uncovered for about 10 minutes.
NOTE: this can be made up to 3 days ahead and stored in an airtight container in the refrigerator.
