- This sauce will last three months in the refrigerator
- This recipe is naturally gluten-free and vegan
Ingredients
You will see many recipes that call for dried onion powder or granulated garlic. While dried spices are fine (and we use them too), taking the extra step to sauté and use fresh ingredients will go a long way in the flavor arena.
- Yellow onion – for the right balance of onion flavor and sweetness. As it sautés in the pan it will mellow out and even sweeten slightly. If you use a red onion, the sauce will have a more pronounced onion flavor.
- Ketchup – to make it easy so you don’t have to balance a ratio of tomato sauce and tomato paste to get the right flavor.
- Molasses – key for a KC-style sauce as it adds the element that makes it authentic. As the molasses simmers and the sauce reduces it takes on the smoky flavor without the need for liquid smoke.
- Brown sugar – this sweetens the sauce and provides the right balance with the acid.
- Apple Cider Vinegar – to finish to the sauce. We add water to thin out the sauce as needed.
- Cayenne pepper – for a touch of heat. If you don’t want heat you can leave this out, or cut it in half.
- Dried spices – to add more flavor, like chili powder, paprika, salt, and pepper.
How to Make BBQ Sauce From Scratch
It’s quite simple. All you really need to think about is finding the balance between sweet, which will come from your sugar, molasses, and ketchup, savory and heat, which is driven by onions, garlic, peppers, or dried spices. And the final touch is acid, which helps with a strong and complex finish to the sauce. You can get acid from apple cider or white vinegar, or even mustard.
Let the combination simmer together and you have sauce!
How to Make Kansas City BBQ Sauce
- Soften Fresh Ingredients: Start by warming up a stock pot, then sautéing the onions until translucent and soft, but not caramelized then add garlic and stir for another minute.
- Add Liquids: Add ketchup, molasses, apple cider vinegar, and water and bring to a simmer.
- Add Seasonings: Finally add everything else.
- Blend: Using a hand immersion blender, blend the ingredients to grind up the onion and garlic and get a nice smooth consistency.
- Simmer: Bring back to a simmer and cover for another 20 minutes. Remove from heat, and then using a funnel, pour the sauce into a mason jar. This helps the sauce reduce slightly and brings the flavors together.

Frequently Asked Questions (FAQ)
Adding a little apple cider vinegar is a great way to maintain a shelf life on your sauce. How long can you keep a fresh BBQ sauce you may ask? Up to three months in the refrigerator.
Sauces come in all flavor profiles. Really it reflects the flavors regionally that evolved around the country. In the Carolinas, you have vinegar-based sauces (among others). In Texas, you’ll find less of a sauce and more of a flavor mop while cooking. And in Alabama you’ll find a mayo-like white sauce.
But in Kansas City, it’s all about the sweet and slightly spicy tomato and molasses based sauce. The kind that many of us grew up with. The kind that KC BBQ joints tend to toss their famous burnt ends in. If you haven’t been to Oklahoma Joe’s, or some of the other pit houses in the state, it is worth the trip. You can learn more about other styles of BBQ sauces at this post about BBQ sauce styles.

I bbq low ‘n slow on a pellet grill and it’s perfect for its bark and its bite 😉 I’ve made it at least 5 times and it’s always fantastic. So easy I can’t see why anyone would buy sauce off the shelf
That is so awesome! Thanks so much for leaving such great feedback!
Classic, easy, delicious!
The ingredients list calls for apple cider vinegar, but it is never used in the description.
I cannot believe we did not catch that! Updated and thanks for pointing out! Add to the other liquids is the right answer. 🙂
KC BBQ Sauce is my absolute favorite! Sweet, sticky and a little spicy- this recipe is perfect!
