A while back (2018), we spent a year living in Kansas City, and it gave me a whole new appreciation for BBQ. The ribs are just next level. The best ever! This homemade version was inspired by those flavors just a chunkier bbq sauce, and itโ€™s still a favorite in my home.

How to Make Homemade BBQ Sauce

This sauce is simple and foolproof, but the flavor? Next level. Itโ€™s also very forgiving, so feel free to tweak it a bit. Donโ€™t like chunks of onion? Blend it. Want it spicier? Add more chili powder or hot sauce. But whatever you do โ€” donโ€™t skip the onions unless you absolutely have to. They add so much depth.

  1. Heat 1 tablespoon of vegetable oil or butter in a skillet over medium-high heat.

  2. Once hot, add 1/2 cup chopped red onions. Sautรฉ until soft and translucent, about 3 minutes.

  3. Transfer the onions to a medium saucepan. Add:

    • 1 cup ketchup

    • 1/4 cup molasses (use a good quality one!)

    • 1/4 cup apple cider vinegar

    • 1/4 cup brown sugar

    • 2 tablespoons Worcestershire sauce

    • 1 tablespoon spicy brown mustard

    • 2 tablespoons lemon juice

    • 1/2 teaspoon garlic powder

    • 1/2 teaspoon onion powder

    • 1/2 teaspoon chili powder

    • 1/4 teaspoon black pepper

    • Optional: 1/4 teaspoon liquid smoke (or less โ€” see notes)

  4. Stir everything together and bring to a boil over high heat.

  5. Reduce the heat to low and let it simmer for 20โ€“35 minutes, stirring occasionally, until thickened to your liking.

Tips for the Best BBQ Sauce

  • Simmer to your preference: The longer it simmers, the thicker, richer, and more flavorful it becomes. Want a thinner sauce? Cut the simmer time in half.

  • Smooth it out: For a silky texture, blend the finished sauce using an immersion blender, food processor, or blender.

  • Let it rest: Chill it in the fridge for a day before using. This helps all the flavors meld together beautifully.

  • Go easy on the liquid smoke: A little goes a long way. If youโ€™re unsure, stir a drop into a spoonful of sauce and taste before adding it to the full batch. Some people love it, others not so much.

  • Storage: Keep your BBQ sauce in an airtight container in the fridge for up to 1 week.

    Ways to Use This Sauce

    Itโ€™s incredibly versatile. Use it on:

    • Slather on, BBQ chicken sliders

    • BBQ chicken sliders

    • Burgers or meatloaf

    • Grilled ribs, drumsticks, or wings

    • Baked beans or even mac and cheese

    This is the kind of sauce that makes you excited for summer. But honestly, I use it all year long.

Notes

Tips to make this bbq sauce

  • For a smoother sauce: After itโ€™s cooked, use an immersion blender right in the pan or transfer it to a blender/food processor. Blend until silky smooth.
  • Flavor improves overnight: Let the sauce rest in the fridge for a day before using. The flavors will deepen and mellow beautifully.
  • Use good-quality molasses. It makes a noticeable difference in depth and sweetness.
  • Liquid smoke adds a backyard barbecue vibe without needing a smoker. Itโ€™s optional โ€” still fantastic without it. Start with a tiny amount (about 1/4 teaspoon) and taste as you go. A little truly goes a long way.
  • Pro tip: Some folks arenโ€™t into liquid smoke. To test if itโ€™s for you, stir a dab of it into a spoonful of sauce and taste before adding it to the whole batch.
