There are three key things necessary for a truly good pizza; the crust, the toppings, and the sauce. Here’s how to make the best homemade (and low carb) keto pizza sauce from scratch in only 5 minutes.

How to Make Low Carb Keto Pizza Sauce

  • Combine the ingredients. Add the tomato paste, hot water, apple cider vinegar, olive oil, sweetener, grated Parmesan cheese, minced garlic cloves, dried oregano, dried basil, dried thyme, cayenne pepper, salt, and pepper in a small bowl and mix to combine. Use the best quality ingredients you can find for this because it will make a difference!
  • Refrigerate. You can either use the sauce immediately or transfer it into a jar to refrigerate until you’re ready to use it.

Can I Use Canned Keto-friendly Tomato Sauce Instead?

If you’re trying to keep your homemade pizzas as low carb and keto-friendly as possible, then I really don’t recommend using canned tomato sauces. They’re usually full of hidden sugars, preservatives, and other harmful additives.

However, if you do find canned tomatoes with no sugar added, you can blend it with an immersion blender until smooth.

Canned tomato paste is different in that it usually only contains a dried out, thick tomato concentrate. It’s also quite good for you, with studies finding it beneficial with helping to protect against cardiovascular disease. (1)

  1. This was great. However, I sauteed the combined sauce to thicken it a bit. I like a tangy pizza sauce and this fits the bill.
