Super Tasty Low-Carb Pizza Sauce

This low-carb pizza sauce doesn’t contain all the added sugar most store-bought sauces have, which makes it delightfully low carb, but still super tasty.

The difficult thing about store-bought pizza sauce is that it’s often not appropriate for a low-carb or keto diet, because it’s packed with added sugars. Making your own at home is an easy way to avoid that.

Since tomatoes themselves have some carbs, it’s imperative not to add any extra sugar. This recipe has absolutely no added sugar, and it’s incredibly tasty.

With just 4 ingredients, this is probably the easiest pizza sauce you’ve ever made. I’ve seen recipes that include 10 or more ingredients, but I really don’t think that’s necessary.

The real key to great sauce is in the amount of time it’s stewed. A pizza sauce can be mixed together in minutes, but if it’s not cooked on the stovetop for at least 20 minutes, it’s just not going to have the same flavor and intensity, no matter how many ingredients you add.

One consideration you’ll need to make is whether to puree the tomatoes or leave them in chunks. The sauce will be a bit chunky when using chopped tomatoes in the can.

That’s never bothered me enough to take the time to puree the sauce, but if you prefer smooth sauce, you can puree it very quickly in the pot with an immersion blender.

What About the Crust?

There are a few different variations of low-carb pizza crust out there. Here’s our recipe for fathead pizza crust, which is the one I prefer most. You can also make a cauliflower crust.

We’ve even got a recipe for a ground chicken pizza crust if you’re feeling like trying something different.

One serving of fathead pizza crust has 4 net grams of carbs. So when you’re totalling up all the carbs in the pizza you make, be sure to add the crust and the sauce together. In 1/4 of a pizza, you will get 5 net grams of carbs between the crust and the sauce.

    Such a great idea to make your own sauce to keep the sugar and carb count as low as possible. It sounds like the perfect pizza sauce to me!
