Isn’t it the worst when you’ve got your pizza dough all rolled and ready for pizza sauce, yet you look through you cupboards and panic, because there aren’t any tins of pizza sauce?

With this Sugar Free Pizza Sauce in your recipe book, you’ll never have to freak out again. Of course there is the added bonus that you can add, or minus, any ingredient you like or don’t like.

I hate that store bought pizza sauce has sugar in it. I mean, I get it. Tomatoes are super acidic, so sugar has a more important role than just sweetening up the sauce. It cuts the acidity down.

But honestly? Pizza sauce does not need sugar. Homemade pizza sauce, minus all the preservatives, tastes amazing. With a few simple ingredients, you’ve got yourself a sugar free pizza sauce you can make in just a few minutes, so you never have to buy pizza sauce, ever again.

What you’ll need to make a sugar free pizza sauce

Besides spices, there are only two other ingredients that go into the sugar free pizza sauce : tomato paste and water.

I always buy organic tomato paste, unless it’s made somewhere like Italy where GMO products are banned.

For spices you will need oregano, basil, garlic, onion, salt and pepper.

Pretty simple, right?

Sugar Free Pizza Sauce recipe

You won’t even believe how easy it is to make this sugar free pizza sauce. The hard work of blanching and peeling tomatoes, then simmering them down into a sauce has already been taken care of for us by buying organic tomato paste.

Don’t get me wrong, making things from scratch is super exciting and I just love to do it, but sometimes you just don’t have the hour and a half to spare.

Bowl with tomato paste and the dried herbs, ready to be mixed.

Instead we will just empty that can of tomato paste into a bowl and add oregano, basil, onion powder, garlic powder, sea salt and pepper. Whisk it well then add water until you have the desired consistency. I like 3/4 cup water, but you may like a thicker or thinner sauce.

Now it’s ready to be spread over a Fathead Pizza Crust or any other pizza crust you may have.

Can you eat pizza sauce on keto?

You sure can!

If you are going the store bought route, be careful which pizza sauce you choose because they tend to have large amounts of sugar.

  1. Gloria | Homemade & Yummy

    Homemade everything is so much better. We love making pizza on the grill. This is perfect. I think I might even try freezing some so I will always have some on hand.

  2. Yes! Sugar is needed in tomatoes when making large batches of tomato sauce. But if making a small quantity you barely need any, really. I just don’t get why there’s so much sugar in all tomato products. I remember this used to be an issue when we were living in Poland as too many pasta sauces tasted just too sweet. Easiest option was for me to always make my own. My husband and I are Italian and we just don’t agree with this crazy use of sugar in tomato sauce, it doesn’t even taste right. Even if I’m not on a no-sugar diet I’m totally with you on this one. No sugar in pizza and pasta sauce; just a half teaspoon if making a huge pot.

    • Wow, thanks Eva! It is crazy, isn’t it? I completely agree, it starts to not even taste like tomatoes after a certain point.

  3. It looks so good, and easy to make! The best part is that its sugar free. Love it.

  4. Love it! I’ve been making a lot of homemade pizza lately and always just use a premade sauce (cause I’m lazy to make my own). Love that your recipe is so simple, so I can just make a big batch and use it for the whole week!

  5. Homemade is always the way to go. Pizza, to me, should be a food group. I love how simple your recipe is as I’ve seen others that are just so complex with 47 ingredients. This would be great to make in bulk and freeze too!

    • Thanks Lori! I thinking making pizza from whole tomatoes is pretty awesome too, but this recipe is just so great and simple, never mind fast!

  6. I’m SO guilty of buying jarred pizza sauce…but I have been working hard to cut extra sugar out of my diet and this pizza sauce could not have come at a better time!

    • I hear ya, Kylie, it’s a hard one to cut out at first, but it gets easier and easier until you don’t think about sugar at all!

  7. I make pizza pretty often, so having a solid sauce recipe is a must. I can’t wait to try yours and see how it turns out – I am sure it will be perfect!

  8. Sounds perfectly seasoned! Love that’s is low carb too 🙂

  9. Homemade pizza is simply the best. It’s so fresh, flavorful and I love the fact that we can customize it as per ones preference.

  10. The TRUTH!! I have had numerous occasions when I have dinner started and go to the pantry and think NOOOOOOO. This recipe is gonna be my life saver!

    • Hahaha right?! It used to be the most horrible feeling, which is why I decided enough was enough, I would make it so that this never happens again!

  11. I love making meals from scratch – everything from the sauce to the dough and beyond. Your sauce looks so delicious and I love that it doesn’t have any added sugar. Can’t wait to give it a try next time I make pizza!
