Homemade BBQ Sauce with Molasses and Smoked Paprika
Not rated yet. Be the first.
Onion and garlic go into butter first, then molasses and smoked paprika, and the whole kitchen smells like a Sunday cookout. Make it the day before and the fridge finishes the job.
The short version
Soften onion and garlic in butter, stir in ketchup, vinegar, brown sugar, molasses, mustard and spices, then simmer 15 to 20 minutes until thick. It tastes better after a night in the fridge, so make it a day ahead if you can.
What makes ours better
small changes, very loud compliments
-
Cook fresh onion and garlic first. Five minutes in butter takes the raw edge off and gives the sauce body and a savory backbone that powders alone can't.
-
Use smoked paprika and molasses. Smoked paprika gives real smoke without the chemical edge of liquid smoke, and molasses brings a dark, bittersweet depth that plain sugar misses.
-
Stir in the last splash of vinegar off the heat. Long simmering mutes vinegar. Adding a spoonful at the end brings the tang back so the sauce tastes bright, not just sweet.

Steps
go slow. the good part can’t be rushed.
-
Soften the onion and garlic
Melt the butter in a medium saucepan over medium heat. Add the onion and cook, stirring, for about 5 minutes until soft and translucent. Add the garlic and stir for 30 seconds, until you can smell it.
About 5 min. Cook mode has a timer for this step.
-
Stir in the spices
Add the smoked paprika, chili powder, black pepper and cayenne. Stir for 15 seconds so the spices toast in the butter.
-
Add the rest
Stir in the ketchup, ⅓ cup of the vinegar, brown sugar, molasses, Worcestershire, mustard and salt until smooth.
-
Simmer until thick
Bring to a bubble, then lower the heat to medium-low and simmer for 15 to 20 minutes, stirring often. The sauce is ready when it's glossy and thick enough to coat the back of a spoon, and a line drawn through it with a spatula stays open for a second.
Use a pan with a lid ajar or splatter screen. Ketchup sauce spits, and it stains.
About 15 min. Cook mode has a timer for this step.
-
Finish and taste
Off the heat, stir in the last tablespoon of vinegar. Taste and adjust. Add salt if it's flat, a little brown sugar if it's sharp, or more cayenne for heat. If it's too thick, stir in a splash of water.
-
Cool and rest
Let the sauce cool, then spoon it into a jar. Use it right away, or refrigerate overnight for the best flavor.
Good to know
the stuff I’d tell you over the phone
- For a smooth sauce, whiz it with an immersion blender after simmering. That's useful if you find onion pieces off-putting on a brushed-on glaze.
- On ribs and chicken, brush the sauce on during the last 10 minutes of cooking. The sugar burns if it goes on earlier.
- For smoky heat, stir in 1 to 2 teaspoons of chopped chipotle in adobo in step 3.
- Storage. Refrigerate in a jar for up to 2 weeks. Freezes for 3 months; thaw overnight in the fridge. This sauce is not tested for canning.
Questions, answered
asked and answered at the kitchen counter
Can I make BBQ sauce without liquid smoke?
Yes, and this recipe does. Smoked paprika gives a clean, natural smokiness. For more, add a teaspoon of chipotle in adobo.
How do I thicken BBQ sauce?
Simmer it longer with the lid off; it thickens as the water cooks out. It also thickens in the fridge, so stop when it's a little looser than you want.
How do I thin BBQ sauce?
Stir in water or a splash of cider vinegar, a tablespoon at a time, over low heat.
Can I use brown sugar instead of molasses?
Yes. Use 3 tablespoons more brown sugar. You'll lose some of the dark, slightly bitter depth, but it will still taste good.
How long does homemade BBQ sauce last?
Up to 2 weeks in the fridge in a clean jar, and 3 months in the freezer.
How do I make it spicier or sweeter?
For heat, add cayenne or chipotle in small amounts. For sweetness, add brown sugar a tablespoon at a time, tasting between additions.
