This keto barbecue sauce is perfect for those cutting out their sugar consumption. This sauce works well on pork and beef ribs, low-carb meatloaf, and chicken!

We’ve all been there. You want to enjoy some delicious grilled ribs, but you’re watching your sugar intake. So, you make a trip to the grocery store and pick up one of those keto barbecue sauces on the shelf. You take it home, open it up, taste it, and instantly regret your purchase. Why? Because it was too sweet or didn’t have that quintessential BBQ flavor you’re looking for; a little sweetness mixed with tartness, the piquant flavor of chilis, and the overall smokiness of low and slow BBQ.
Our keto barbecue sauce doesn’t suffer from that problem because we build the flavors and add the sweetener incrementally. Most keto-friendly sauces include sugar-free sweeteners like sucralose that are too sweet. Some contain erythritol, which can cause digestive upset in some people. We’ve sidestepped those options and used monk fruit sweetener in our recipe. The results were amazing! This recipe makes 3 cups of keto barbecue sauce, with 12 portions or 1/4 cup serving per person. Each serving contains 3 grams of carbs.
What is Monkfruit Sweetener?
Monk fruit or lo han guo is a small round-shaped fruit from China. These fruits have become globally popular with the emergence of sugar-free, paleo, and keto diets that require calorie-free, low sugar sweeteners. The mogroside, the sweetest part of the monk fruit, makes up the sweetener. The fruit is crushed, and the mogroside is lifted from the juice, processed, and turned into monk fruit sweetener. It is quite sweet, with 1/3 cup of monk fruit sweetener equalling 1 cup of sugar. When making items like keto barbecue sauce, it is best to start small and increase the amount incrementally.
