17th Street Barbecue Sauce Recipe: Sweet and Smoky Competition-Style Blend

This competition-style sauce delivers the perfect balance of sweet and smoky that defines legendary barbecue. I developed it after years of tweaking blends for local cook-offs.

What sets it apart is the deep caramelized base that clings to ribs or chicken, creating that signature sticky glaze. It keeps well for weeks in the fridge.

Ingredients for 17th Street Barbecue Sauce

Nine simple ingredients. One legendary sauce. Sweet, smoky, stick-to-your-ribs good.

The molasses and brown sugar create that signature caramelized base—use the good stuff. Bragg or Annie’s for the vinegar if you want organic. Ketchup matters more than you think; Heinz is my go-to for consistent flavor. Liquid smoke can be polarizing, but Colgin hickory is the gold standard for competition sauces. Most grocery stores carry it near the BBQ supplies.

No molasses? Honey or maple syrup work in a pinch (but adds different sweetness). Out of apple cider vinegar? White vinegar plus a pinch of sugar gets close. Want more heat? Add cayenne at 0.25 tsp. If you’re skipping liquid smoke (I get it), smoked salt at 0.5 tsp can help. The sauce thickens as it cooks down—don’t rush it.

This keeps for 3-4 weeks in the fridge—if it lasts that long. Glass jar works best. For longer storage, freeze in ice cube trays (about 3 months). The flavors actually deepen after a day or two, so make it ahead if you’re using it for a cookout.

Step-by-Step Instructions for Sweet and Smoky Barbecue Sauce

This method guarantees a glossy, well-balanced sauce with perfect consistency.

Step 1: Combine Wet Ingredients in Saucepan

In a medium saucepan over medium heat, add the 2 cups Ketchup, 0.5 cup Apple Cider Vinegar, and 0.25 cup Molasses. Stir with a silicone spatula to fully incorporate. The ketchup’s thickness will help suspend the vinegar and molasses evenly.

Watch for tiny bubbles forming at the edges—that’s your signal the mixture is warming through. Don’t let it come to a boil yet; we’re just bringing everything to the same temperature before adding the rest. This gentle start prevents the sugars from caramelizing too early.

Step 2: Incorporate Dry Ingredients and Seasonings

Add the 0.75 cup Brown Sugar, 2 tbsp Worcestershire Sauce, 1 tsp Liquid Smoke, 1 tsp Garlic Powder, 1 tsp Onion Powder, 1 tsp Smoked Paprika, and 0.5 tsp Black Pepper to the saucepan. The brown sugar will start dissolving immediately in the warm liquid.

Stir constantly for 2-3 minutes until the brown sugar fully dissolves and the sauce takes on a uniform dark red color. The liquid smoke and smoked paprika will deepen the aroma at this stage—you should start smelling that characteristic barbecue scent.

Step 3: Simmer to Thicken the Sauce

Reduce heat to medium-low and let the mixture simmer uncovered for 15-20 minutes. Stir every 2-3 minutes to prevent sticking, especially at the bottom where sugars can burn.

You’ll notice the sauce gradually thicken and darken in color. It’s ready when it coats the back of a spoon and leaves a clear trail when you run your finger through it. The volume will reduce by about 20-25% during this process.

Step 4: Adjust Consistency and Cool

Remove from heat and let the sauce cool for 5 minutes. It will continue to thicken slightly as it cools. If it’s too thick after cooling, thin with 1-2 tablespoons of water or apple cider vinegar.

Taste and adjust seasoning if needed, though the balance of sweet, tangy, and smoky should be spot-on with these proportions. The sauce will have a glossy sheen and cling beautifully to meats when used for basting or serving.

Pro Cooking Tips for 17th street barbecue sauce

Perfect Simmer Technique

Keep your sauce at a gentle simmer—not a boil—to prevent burning the sugars. Use a heavy-bottomed saucepan for even heat distribution. I learned this the hard way when my first batch scorched at the bottom.

Stirring Strategy

Stir every 2-3 minutes during simmering, using a silicone spatula to scrape the bottom. The molasses and brown sugar love to stick, especially in the final stages when the sauce thickens.

Thickness Test

Your sauce is ready when it coats the back of a spoon and leaves a clear trail. If it’s too thin after 20 minutes, simmer 5 more minutes. Too thick? Thin with 1-2 tbsp apple cider vinegar. 🌡️

Flavor Development

The liquid smoke and smoked paprika bloom best when added to warm liquid. Let them sit in the sauce for 2-3 minutes before simmering to deepen those smoky notes we all crave.

Resting Matters

Always let your sauce rest for 10 minutes after cooking. The flavors meld and the consistency evens out. I taste mine at this stage to confirm the sweet-tangy-smoky balance is just right.

Storage Pro Tip

Transfer to a glass jar while still warm to create a vacuum seal as it cools. This extends fridge life to 4 weeks and prevents mold growth. 💡
