The rhubarb is the star here—look for firm, crisp stalks with vibrant color at your local farmers market or grocery store. Avoid woody or limp pieces. I like using organic ketchup (like Annie’s Natural) for a cleaner base, but any quality brand works. The molasses adds that deep, rich backdrop—Brer Rabbit is a reliable choice if you’re not making it from scratch.

No fresh rhubarb? Frozen works in a pinch—just thaw and drain well first. Out of molasses? Honey or maple syrup can substitute (but remember, use maple for strict vegan). Want more heat? Add a pinch of cayenne. The vegan Worcestershire is non-negotiable for authentic flavor—Annie’s or Edward & Sons are widely available and taste great.

This sauce keeps beautifully. Store in an airtight jar in the fridge for up to 2 weeks, or freeze for 6 months. The flavors deepen over time, so making it a day ahead is actually ideal. Perfect for slathering on ribs, chicken, or even as a dipping sauce for fries.

Step-by-Step Instructions for Rhubarb BBQ Sauce

This method ensures a perfectly balanced sauce with the ideal consistency for grilling.

Step 1: Cook the Fresh Rhubarb

Combine the 4 cups Fresh Rhubarb in a medium saucepan over medium heat. Stir occasionally as it begins to soften and release its juices. This should take about 5-7 minutes.

You’ll notice the rhubarb breaking down into a chunky puree. Keep cooking until it reaches a soft, mashable consistency. The tart aroma will become more pronounced as it cooks down.

Step 2: Add Wet Ingredients and Simmer

Stir in the 1 cup Ketchup, 0.5 cup Apple Cider Vinegar, 2 tbsp Molasses, and 1 tbsp Worcestershire Sauce. Bring the mixture to a gentle boil, then reduce heat to maintain a steady simmer.

Let this cook for 10-12 minutes, stirring frequently to prevent sticking. The vinegar’s sharpness will mellow as it reduces, while the molasses adds rich depth to the base.

Step 3: Incorporate Sweetener and Spices

Add the 0.75 cup Brown Sugar, 1 tsp Smoked Paprika, 1 tsp Garlic Powder, 1 tsp Onion Powder, and 0.5 tsp Salt. Stir well to dissolve the sugar completely and distribute the spices evenly.

Continue simmering for another 8-10 minutes until the sauce thickens enough to coat the back of a spoon. The smoked paprika will deepen the color to a rich reddish-brown.

Step 4: Finish and Cool

Remove from heat and let the sauce cool for 5 minutes. It will thicken slightly as it cools. Taste and adjust seasoning if needed, though the measured ingredients should provide perfect balance.

For a smoother texture, blend with an immersion blender until smooth. Transfer to an airtight container once completely cooled. The sauce will keep in the refrigerator for up to 2 weeks.

Best Sauces and Condiments for This rhubarb bbq sauce

Classic Pairings

This sauce works beautifully with pork ribs—the tartness cuts through the fat perfectly. I especially love it on baby back ribs slow-cooked for 3-4 hours. Brush it on during the last 30 minutes of cooking for best results. 🔥

Poultry Perfection

For chicken, use it as a glaze on grilled thighs or wings. Toss 2 lbs of wings in ½ cup sauce during the final 10 minutes of grilling. The sauce caramelizes beautifully, creating a sticky, finger-licking coating.

Beef and Burgers

Slather it on pulled beef sandwiches or use as a topping for smash burgers. The acidity from the rhubarb balances the richness of beef. I like adding a spoonful to the meat while cooking for extra moisture.

Unexpected Uses

Try it as a dipping sauce for sweet potato fries or crispy Brussels sprouts. The contrast between the sweet, smoky sauce and the veggies is incredible. It also makes a killer marinade for tofu or tempeh—let it soak for at least 2 hours.

Cheese Pairings

For a gourmet touch, serve with sharp cheddar or smoked gouda. The tang of the sauce complements the bold cheese flavors. I often make grilled cheese sandwiches with this sauce as a spread. ✨

Salad Dressing

Thin it with a little apple cider vinegar and olive oil to create a unique salad dressing. Drizzle over spinach salad with strawberries and feta for a sweet-tart twist that always impresses at my local BBQ competitions.
