This sauce leans more towards KC Masterpiece - so thick, quite sweet, but good on everything.

Stuff You’ll Need

  • 1 teaspoon vegetable oil (any neutral oil)
  • ½ sweet onion, minced
  • 2 cups low-sodium chicken broth
  • ½ cup root beer
  • 2 tablespoons cider vinegar
  • ½ cup dark corn syrup
  • ¼ cup molasses
  • ¼ cup tomato paste
  • ¼ cup ketchup
  • 1 tablespoon brown mustard
  • 1½ teaspoons hot sauce (like Frank’s)
  • ¼ teaspoon garlic powder
  • 1/8 teaspoon liquid smoke (optional)

Notes Before Making

If you prefer a smoother, thinner texture, you can strain it after cooking or use an immersion blender.

Cook the Onions First

Heat oil in a saucepan over medium-high until shimmering; Add onion and cook until softened and fragrant, ~5 minutes.

Add Everything Else

Whisk in all remaining ingredients except the liquid smoke.

Bring to a boil, then reduce heat to medium and simmer until the sauce thickens and reduces to about 2 cups, this will take ~30 minutes.

Optionally, Add Liquid Smoke and then Store

Stir in liquid smoke, if using.

Let cool, then refrigerate in an airtight container for up to 2 weeks.
