Ingredient Talk
I skipped the onion once, thinking it would save carbs, but I didn’t love it. It tasted flat and too much like a can of tomato sauce for me.
I used crushed tomatoes, but if you have diced or whole tomatoes, add about 10 minutes to the cooking time. Puree the cooked sauce with an immersion blender to your desired texture.
The balsamic vinegar adds richness and a little sweetness. I tested it with red wine vinegar and skipped it entirely once. Both were fine, but balsamic is the version I keep coming back to. Just make sure you read the label, because carb counts can vary widely between brands of balsamic vinegar. If you don’t want to use vinegar, you can swap in tomato paste.
Ad-Ins
I do sometimes add extras to this sauce when I’m in the mood. I’ve added ¼ cup of freshly grated Parmesan cheese, a pinch of crushed red pepper flakes, onion powder, and dried basil. All worked great.
If you want a sweeter low-carb pizza sauce, make sure you choose one that will keep this pizza sauce keto. You can use your favorite, but I found that we liked 2 tablespoons of allulose better than 2 tablespoons of erythritol, which, to me, got a little too sweet.
As always, if you are tracking closely and make any adjustments, make sure you recalculate the net carbs.

Tips & Tricks
- If you find the pizza sauce bland, you may want to use pizza seasoning because it has a little more flavor. If you are using Italian seasoning and you want more flavor, you can add in ½ teaspoon of dried oregano.
- If dried spices aren’t your thing, and you’d prefer to use fresh herbs, stir them in in the last 5 minutes of cooking.
- This sauce is great to make ahead. This keto pizza sauce recipe actually improves after sitting. Store it in the fridge for up to five days or freeze in small portions so you have it ready to pull out any time you want to make homemade pizzas.
