Is Pizza Sauce Keto?

Although pizza sauce contains keto-friendly ingredients, like herbs and tomatoes, not all tomato sauces are good for a keto diet, because they contain added sugar. Skip the extra carbs and make the best keto friendly pizza sauce at home instead — it’s so easy and tastes authentic!

Ingredients You’ll Need

This section explains how to choose the best ingredients for sugar-free pizza sauce, what each one does in the recipe, and substitution options. For measurements, see the recipe card below.

Olive Oil – For the best tasting sauce, use a high quality variety. I recommend extra-virgin. Avocado oil will also work if that’s what you have, but the flavor is better with EVOO.
Tomato Paste – Adds rich tomato flavor for a classic sauce.
Dried Herbs – Oregano, basil, and marjoram are traditional herbs in this keto sauce for pizza. However, you could substitute an equivalent amount of homemade Italian seasoning if needed.
Dried Spices – Garlic powder, onion powder, and fennel seed. You can also add a sprinkle of red pepper flakes if you like.
Salt & Pepper
Balsamic Vinegar – Adds subtle sweetness and body to this sauce. You could skip it, or add Powdered Besti (which dissolves easily, unlike other sweeteners) if you like more sweetness.
Water – To thin out the sauce.

How To Make Keto Pizza Sauce

Stir. To make low carb pizza sauce, simply add all ingredients to a bowl and stir until smooth. If desired, thin the sauce out with additional water.

TIP: For extra smooth sauce, blend ingredients in a blender instead.

Use. The sauce is ready to use on your favorite pizza (see ideas below). No cooking required!

I made this, with a slight variation because of a shortage in my pantry. I used a small can of tomato sauce, and a little squeeze tube of Paste, and proceeded without adding water. It worked fine. Good stuff!!

I took the time to combine all of the seasonings together making a big batch and put in a storage bowl so that I can just sprinkle/add to the tomato sauce as needed. I love these seasonings combined, tastes so much like pizza sauce!

I made this and it turned out good. I used a 6 oz can of tomato paste because that’s what I had. I don’t like fennel so I left that out. I used parsley in place of the marjoram since I didn’t have marjoram. I did use a little bit, 1/2 tsp, of sweetener and extra garlic powder. Oh, also needed more water because I cooked it on low for about an hour.

The added sugar in most tomato sauces was not something I was aware of until just a few years ago! So making a sugar-free tomato sauce is so helpful!

This pizza sauce had so much flavor! Using store-bought is frustrating because it’s hard to find one that’s low in sugar, there’s always some added. Glad I have this recipe now!

This pizza sauce was PERFECT for my cauliflower crust pizza! It was super easy and quick to whip up, and it really did taste better than any store bought sauce I’ve bought. This is definitely going to be my go-to recipe when making homemade pizza from now on!
