This Keto BBQ Sauce has no added sugar and uses Sukrin Gold all natural brown sugar substitute, and it tastes just as good as store-bought BBQ sauce.

The ingredient you have to watch out for when you’re on a keto diet using store-bought sauce is added sugar. The sugar content can add quite a few carbs to every serving of sauces like ketchup and BBQ sauce.

This Keto BBQ sauce is easy to make at home and allows you to continue on with your summer barbecuing, even while on a keto diet. You won’t even miss the regular store-bought product you used to buy.

This recipe makes just about 1 cup of bbq sauce. The serving size is about 1 1/2 tbsp. Each serving contains 2 grams of carbs. Keep that in mind if you’re slathering more than this amount on your food.

Ingredients in Keto BBQ Sauce

You don’t need a lot of “keto” products to make this BBQ Sauce happen. That’s the great part about it. It mostly uses ingredients you likely already have on hand.

The two things that help make this a keto sauce is the no-sugar added ketchup and the Sukrin Gold brown sugar substitute. The other ingredients don’t add much in the way of carbs.

Here are the ingredients you’ll need (quantities in the recipe below):

  • Onion and garlic
  • No sugar added ketchup
  • Apple cider vinegar
  • Liquid smoke (don’t leave this out!)
  • Worcestershire sauce
  • Sukrin Gold
  • Salt and pepper

I don’t use a lot of ketchup, but sometimes you need it for something, so we’ve gotten used to eating only no-sugar-added ketchup from Heinz. You don’t have to use that version, there are plenty of others from small producers that are great.

Once you’ve gotten used to no-sugar added ketchup, it’s actually hard to go back to the regular. It’s so sweet!

I use Sukrin Gold in this recipe to replace the brown sugar. I think it has a bit more flavor than white sugar, but if you don’t want to buy Sukrin Gold for this purpose alone, you can use Erythritol, Swerve, Xylitol… whatever granulated sugar substitute you normally use.

Just be aware that some of these might be sweeter than Sukrin, so you might have to adjust the amount used.

The other highlight in this sauce is the liquid smoke. I use a hickory flavored one. You can get many other flavors. Try a few and see what you like best. I wouldn’t suggest leaving it out. This is what makes it taste like BBQ Sauce instead of just vinegary ketchup.

About the Onions

You might know that onions have a high carb count. To keep this sauce low in carbs, and super smooth, I add onion chunks for flavor, that can be removed when the sauce is complete. I just fish them out of the sauce at the end, or strain the sauce through a mesh sieve.

It makes a great tasting smooth sauce, without actually including the onion.

If you don’t care about the extra carbs, or you just love onions, you can leave them in, but then I would suggest chopping them finely, so they blend in. You can puree the sauce at the end to incorporate the onions.

How to Make Keto BBQ Sauce

Start by adding the onion and garlic to a small sauce pan and allow that to simmer over medium-low heat for about 5 minutes, until it becomes really aromatic.

Then add all the remaining ingredients, stir it all together, and let it simmer over medium-low for about 15 minutes. It will cook down a little bit and become browner and more concentrated.

After 15 minutes, turn off the heat and allow the sauce to cool. You can remove the onions with a fork (the lazy version that I’m guilty of sometimes!), or strain it through a mesh sieve to get a super smooth sauce.

Storing Leftover Sauce

You can store any left over sauce in the refrigerator for a couple of weeks. I put it in an air-tight container and use it throughout the week for various dishes.

You could even freeze the BBQ sauce, if you wanted to. When you’re ready to use it, just take it out and reheat it on the stove top. I’ve seen people add sauce to an ice cube tray to freeze, so you can store individual servings. Not a bad idea!

  • Add the onion and garlic to a small saucepan. Saute on medium for 5 minutes until aromatic.
  • Add all additional ingredients and stir well.
  • Bring to the boil, then reduce to medium-low and simmer for 20 minutes.
  • Take the pan off the heat and allow to cool.
  • Strain the sauce into a bowl, discarding the solids.


  • If you don’t want to use ketchup, or can’t find a no-sugar added version, you can substitute with 1/2 cup tomato puree mixed with 1/2 cup water.
  • Any type of liquid smoke works, but I particularly like hickory.
  • The servings size is just about 1.5 tbsp for 2 grams of carbs.
  • If you don’t want to discard the onions, you can finally chop them and keep them int the sauce. If you want a smooth sauce, just puree it in the blender.
  • The sauce can be stored in the refrigerator for up to a week.

    I love a good thick bbq sauce and I wasn’t aware of this brown sugar substitute which I so want to try since I use a lot of brown sugar.
