If your household was anything like mine, your condiment selection would be quite overwhelming. If hoarding condiments were a sport, my mom would win first prize. Seriously, she has a condiment or sauce for anything you are craving. Hot sauces, sweet sauces, spicy sauces, sour sauces, the list could go on. 

Even though she had a treasure trove of sauces in her collection, there was only one that caught my eye- the classic bbq sauce. 

I can’t remember the first time I tried bbq sauce,  but I was instantly converted. I think it comes down to me being a man who loves plenty of flavors and texture. It’s sweet, smokey, savory, and pairs well with pretty much every savory dish.

Is bbq sauce keto? 

Now traditional barbecue sauce is definitely not keto or low carb. In fact, they contain more sugar than even ketchup does, and ketchup is loaded with it! While there are many sugar free sauces available on the market, it is so easy to make your own!

Traditional barbecue sauces can contain up to 100 calories per 2 tablespoon serving, with 25 grams of carbs and sugar. In my sugar free version, each serving contains a mere 12 calories and 2 grams carbs, for a total of 1 gram net carb. Bonus? None of those carbs are from sugar! 

This keto bbq sauce will be your new go-to condiment. It’s so simple to make and requires just a handful of ingredients. It has ALL the necessary flavors of any barbecue sauce out there, minus the sugar and carbs!

How do you make sugar free bbq sauce?

The Ingredients

  • Tomato paste– Tomate paste is a concentrated version of tomato sauce or passata. It is much thicker and has a more intense flavor. Only a small amount will be used and thinned out with water. 
  • Apple cider vinegar– Unlike my ketchup recipe (which used a mix of white vinegar with apple cider vinegar), we will be using strictly apple cider vinegar here. The subtle apple flavor is perfect for the barbecue flavor. 
  • Liquid smoke– A secret ingredient to give this sauce the more smoky bbq flavor. While relatively flavorless on its own, it intensifies once mixed with all the other ingredients. 
  • Keto Brown sugar– A keto substitute for brown sugar, this ingredient has such a distinct flavor that is synonymous with any good bbq sauce. If you don’t have any of this, you can use erythritol or monk fruit, but the sweetness won’t be as distinct. 
  • Garlic and onion powder– Adds extra flavor. 
  • Salt– To taste!
  • Smoked paprika– Intensifies the smoky flavors of the sauce. Contrary to popular belief, smoked paprika is not spicy! 
  • Water– To thin everything out! 

The Instructions

Add all your ingredients into a small saucepan and whisk well. On medium heat, heat it up until it begins to simmer. Reduce to very low, and mix for 4-5 minutes, until thick. Remove from the heat and let the sauce cool and thicken.

Tips to make the best low carb bbq sauce

  • The longer you simmer the sauce, the thicker it will be. If you’d prefer a thinner sauce, add extra water to it.
  • Taste the barbecue sauce before you remove it from the heat. If it is too tangy, add a little extra sweetener. If it isn’t salty enough, add a dash more salt. 
  • For a spicy kick, add some cayenne pepper or red pepper flakes. Alternatively, you can even stir through some hot sauce or buffalo sauce after it has thickened up.

    1. How will this turn out using Lakanto brown? Have you tried using that? I am celiac and unable to use Sukrin gold as it contains barley malt (gluten) which is a big no,no for celiacs.
