This Keto Barbecue Sauce is bold & tangy, smoky, sweet & spicy and can be customized to your own tastes.

I like to add a little bourbon to mine but the possibilities are endless. There are some great ideas in the post in case you want to shake it up.

Hint: it’s also excellent on grilled veggies.

I know that there is a lot of disagreement as to whether or not BBQ should go on the meat before or after it’s grilled or baked.

We do it both ways around here because there is some difference of opinion right in my own family. This is just a sauce recipe though, so I’ll stick to that and keep my opinion out of it…

The Keto Barbecue Sauce Ingredients:

Your sauce will taste better with some sort of fat in it. You can use whatever type of fat that you want.

I just like this olive oil since it doesn’t have a lot of flavor of it’s own like coconut oil.

I have made a lot of BBQ Sauce in my time I have never understood blending the sauce after you cook it down. Every recipe that I see calls for blending with an immersion blender after the sauce has simmered.

It seems like an easy way to get scalded.

Why not blend the tomatoes before you start? There is no culinary reason to wait for this step.

  • 2 tbsp apple cider vinegar

Red wine vinegar is also excellent in this sauce. Use whatever you have and add more if you like it really tangy.

  • 2 tsp salt
  • 1 tbsp Worcestershire

If I were a gambler I would bet there are going to be some comments about Worcestershire sauce not being “Keto”.  Don’t listen.

A lot of times, well meaning commenters  get a little confused what the Keto Diet is actually about.

Fact: There are no “fat burning” or strictly “Non-Keto” foods.

Being on the Keto Diet means that you keep your personal macros (fat, carbs & protein) and calories under the specified amount for YOUR body. This is usually under 20 grams for most people.

The Keto way of eating is more complicated, but you can eat (gasp, even plain sugar) so long as you don’t go over your personal macros.

Food isn’t “NOT KETO” unless you go over your macros for the day or eat them all at once and trigger a huge insulin spike.

I guess all I really needed to say is that a Tablespoon of Worcestershire in this sauce is okay to have and won’t kick you out of Ketosis. Learn about Keto and do it your way, that’s the only way to get to your goals.

Check out the science behind the Keto Diet (if you are into that), here in the “how to cheat on Keto and get away with it” post….

Sweetness in your Keto Barbecue Sauce

1/4-1/2 cup Allulose

There is a lot of sugar in store bought sauces for a reason. Some sweetness makes Keto Barbecue Sauce delicious.

Of course, you can exchange the allulose with any sweetener that you like but check out this post on low carb sweeteners if you are new to Keto. They all have their their own risks and rewards.

  • 1 tsp Smoked Paprika

This ingredient gives it a smoky flavor.

* Optional and to taste ~ if you like your BBQ SPICY add red pepper flakes. Remember to test it before adding more.

Optional additions to the Keto Barbecue Sauce:

Keto Barbecue Sauce is really easy to customize to your own tastes and if you have ever read one post of mine you know that I encourage experimentation in the kitchen.

(Don’t forget to share your tips with us in the comments if you come up with something great!)

Here are just a few ideas to get you started:

  • A tablespoon of bourbon
  • Use Golden Allulose
  • Dried onions
  • Finely Chopped Jalapeno
  • Orange Zest
  • Coarsely ground black pepper
  • Dried Sage
  • Dried Thyme
  • Fennel Seed
  • Celery Seed
  • Liquid Smoke
  • Habanero Sauce

The Keto Barbecue Sauce Instructions:

Here come the super complicated instructions…

  • Blend canned or fresh tomatoes smooth.
  • Add all ingredients to a saucepan.
  • Bring to a boil, lower the heat and let simmer for about 30-40 minutes. If you want a thicker sauce let it simmer until it reaches the consistency you like.
  • Store in the fridge for 10 days in a glass jar. Or, do a canning bath or freeze if you won’t use it all by then.

Want to learn about home canning? It’s not as hard as you might think.

That’s it for the Keto Barbecue Sauce today~

I hope you love it, and I would be so happy if you left a comment about the awesome ways you changed yours up to fit your tastes!

Cheers for now beautiful Keto People!
