How to Make Homemade Rhubarb Barbecue Sauce

Making your own rhubarb barbecue sauce is simple and requires just a few ingredients. Here’s how to create this sweet, tangy sauce from scratch.

Ingredients for Rhubarb Barbecue Sauce:

  • 3 cups chopped rhubarb (fresh or frozen)
  • ½ cup brown sugar
  • 1 tablespoon olive oil
  • 1 small onion, finely chopped
  • 2 cloves garlic, minced
  • 1 cup apple cider vinegar
  • 1 cup tomato paste
  • 1 tablespoon soy sauce (or vegan Worcestershire sauce for a vegan version)
  • 1 teaspoon smoked paprika
  • ½ teaspoon ground black pepper
  • 1 teaspoon ground mustard
  • 1 teaspoon chili powder (optional for heat)
  • 1 tablespoon lemon juice

Instructions:

  1. Prepare the Rhubarb: In a medium saucepan, combine the chopped rhubarb, brown sugar, and olive oil. Cook over medium heat, stirring occasionally, for about 5 minutes until the rhubarb begins to soften and release its juices.
  2. Cook the Onion and Garlic: Add the chopped onion and minced garlic to the saucepan. Continue cooking for an additional 3-4 minutes until the onion is softened and fragrant.
  3. Add the Liquids: Pour in the apple cider vinegar, tomato paste, soy sauce (or vegan Worcestershire sauce), and stir to combine. Bring the mixture to a simmer.
  4. Season the Sauce: Add the smoked paprika, black pepper, ground mustard, and chili powder (if using). Stir the sauce and let it simmer gently for 15-20 minutes, or until the rhubarb has broken down and the sauce thickens. Stir occasionally to prevent burning.
  5. Blend the Sauce (Optional): If you prefer a smooth sauce, use an immersion blender to blend the sauce directly in the pan. Alternatively, you can transfer the sauce to a blender and puree it until smooth.
  6. Finish the Sauce: Stir in the lemon juice and adjust the seasoning with more salt, pepper, or sugar, if necessary. Let the sauce cool slightly before using it to glaze meats or serve as a condiment.
  7. Serve and Store: Store leftover rhubarb barbecue sauce in an airtight container in the refrigerator for up to 1 week, or freeze it for longer storage.

This rhubarb sauce for pork is also perfect as a glaze or dipping sauce. For more vegetarian BBQ ideas, consider using this sauce as a topping for grilled veggie skewers or tempeh!

Variations of Rhubarb Barbecue Sauce

While the basic rhubarb barbecue sauce recipe is delicious on its own, here are some variations you can try:

  1. Strawberry Rhubarb Sauce: Add 1 cup of fresh or frozen strawberries to the rhubarb mixture for a strawberry rhubarb barbecue sauce that’s extra sweet and fruity. The strawberry flavor will complement the tartness of the rhubarb beautifully.
  2. Smokier Flavor: For a deeper smoky flavor, increase the amount of smoked paprika or add a teaspoon of liquid smoke to the sauce. This will give your sauce a more robust, charred taste perfect for grilled meats.
  3. Spicy Rhubarb Barbecue Sauce: Add more chili powder or toss in a chopped jalapeño pepper to give the sauce some heat. This spicier version is great for those who love a little extra kick with their BBQ.
  4. Sweet and Tangy Version: For a sweeter sauce, increase the amount of brown sugar or maple syrup. This will balance the tangy flavors of the rhubarb and vinegar, creating a more traditional BBQ fruit flavor.
  5. Vegan Version: Use vegan Worcestershire sauce in place of regular Worcestershire sauce for a fully vegan-friendly version of this rhubarb barbecue sauce.
