This Kansas City BBQ sauce is the thick, sweet and tangy red barbecue sauce most people picture when they think of BBQ. Ketchup makes the base, molasses and dark brown sugar add deep sweetness, cider vinegar and yellow mustard balance it, and chili powder, smoked paprika and a little cayenne bring warmth. A sautéed onion and garlic start gives it extra depth. It simmers for about 20 minutes and makes about 2 cups. Brush it on ribs, chicken and pork, or serve it on the side. Below you’ll find how it compares with Carolina sauce, how to adjust it, and how to use it safely on the grill.
What Is Kansas City BBQ Sauce?
Kansas City-style barbecue sauce is a tomato-based sauce that’s thick enough to cling to meat and sweet enough to caramelize. Its signature flavors come from ketchup, molasses and brown sugar, sharpened with vinegar and rounded out with chili powder and other warm spices. It’s the style found on most supermarket shelves.
Carolina vs. Kansas City BBQ Sauce
| Kansas City | Eastern Carolina | Alabama white | |
|---|---|---|---|
| Base | Ketchup, molasses, brown sugar | Cider vinegar, pepper flakes | Mayonnaise, vinegar |
| Texture | Thick, sticky | Thin, watery | Creamy |
| Flavor | Sweet, smoky, tangy | Sharp, peppery | Tangy, peppery |
| Best with | Ribs, chicken, burnt ends | Pulled pork | Smoked chicken |
Kansas City sauce is brushed on and caramelized; Carolina vinegar sauce is splashed onto pulled pork to cut its richness. Try our Carolina vinegar BBQ sauce for pork shoulder, or our Alabama white sauce for smoked chicken. If you prefer a lighter, honey-sweetened sauce, see our honey BBQ sauce.
Ingredients You’ll Need
- Butter (1 tablespoon), yellow onion (1/4 cup, finely minced) and garlic (2 cloves, minced): a savory base. Mince the onion very finely so the sauce stays smooth.
- Ketchup (1 1/2 cups): the thick tomato base.
- Molasses (1/4 cup): deep, slightly bitter sweetness and dark color.
- Dark brown sugar (1/4 cup, packed): extra sweetness that helps the sauce caramelize.
- Apple cider vinegar (1/4 cup): tang to balance the sugar.
- Yellow mustard (1 tablespoon): a little sharpness.
- Chili powder (2 teaspoons) and smoked paprika (1 teaspoon): warmth and a smoky note.
- Black pepper (1/2 teaspoon), cayenne (1/4 teaspoon) and salt (1/4 teaspoon): seasoning and gentle heat.
- Water (1/4 cup): loosens the sauce while it simmers.
How to Make It
- Soften the aromatics. Melt the butter in a medium saucepan over medium-low heat. Add the onion and cook for about 3 minutes, until soft, then add the garlic for 30 seconds.
- Add everything else. Whisk in the ketchup, molasses, brown sugar, cider vinegar, mustard, chili powder, smoked paprika, black pepper, cayenne, salt and water.
- Simmer. Bring to a gentle bubble, then lower the heat and simmer, uncovered, for about 20 minutes, stirring often, until it clings to the back of a spoon. Partly cover the pan if it spatters.
- Finish. Taste and adjust. For a perfectly smooth sauce, blend it briefly. Let it cool slightly before using.
Sweeter, Hotter or Smokier
| You want | Change |
|---|---|
| Sweeter | Add 1 to 2 tablespoons more brown sugar |
| Tangier | Add 1 tablespoon more cider vinegar |
| Hotter | Increase cayenne to 1/2 teaspoon, or add hot sauce |
| Smokier | Add 1/2 teaspoon chipotle chili powder |
| Thicker | Simmer 5 to 10 minutes longer |
Grilling With BBQ Sauce
Sugary sauces burn quickly, so brush the sauce on during the last 10 to 15 minutes of grilling or smoking, and turn the meat often. Pour the sauce you’ll baste with into a separate bowl, and don’t dip a brush that has touched raw meat back into the sauce you’ll serve. Cook chicken to 165°F and pork chops or ribs to at least 145°F, as the CDC recommends.
Storing Leftover Sauce
Let the sauce cool, then refrigerate it in a covered jar within 2 hours of cooking, and keep your refrigerator at 40°F or below, as the CDC recommends. It thickens in the fridge; warm it gently or stir in a splash of water before using.
