Turn Your Morning Coffee Waste into Smoky Barbecue Sauce

Don't toss those spent coffee grounds! With a few simple ingredients, you can transform them into a rich, smoky barbecue sauce that adds depth to grilled meats and vegetables. This zero-waste recipe not only reduces kitchen waste but also infuses your sauce with the subtle bitterness and aroma of coffee, complementing the sweetness of ketchup and molasses.

Ingredients

• 1 cup spent coffee grounds (from your morning brew)
• 1 cup ketchup
• 1/2 cup apple cider vinegar
• 1/4 cup molasses
• 2 tablespoons brown sugar
• 1 tablespoon Worcestershire sauce
• 1 teaspoon smoked paprika
• 1 teaspoon garlic powder
• 1/2 teaspoon black pepper
• 1/4 teaspoon cayenne pepper (optional)

Instructions

1. In a saucepan, combine all ingredients. Stir well to incorporate the coffee grounds.
2. Bring to a gentle simmer over medium heat, then reduce heat to low.
3. Let the sauce cook for 20–25 minutes, stirring occasionally, until it thickens slightly.
4. Remove from heat and let cool. For a smoother texture, blend the sauce with an immersion blender or in a countertop blender.
5. Transfer to a jar and refrigerate. The sauce will keep for up to two weeks.

Use this barbecue sauce as a marinade, basting sauce, or condiment. The coffee grounds add a subtle earthiness that pairs beautifully with pork, chicken, and grilled vegetables.
