I have worked at two pizza places in my life I delivered pizza for one of the places and was a waitress at another. What I am trying to say is I was around a lot of pizza and I ate my fair share. More than my fair share.

I still really love pizza to this day. But now, I make it at home. There is so little that is needed to make good pizza and making your own homemade sugar-free pizza sauce is so easy.

Ingredients for Low Carb Pizza Sauce

  • Canned tomato sauce
  • Canned tomato paste
  • Fresh garlic (if fresh garlic is too strong for you, try using Air Fryer Roasted Garlic)
  • Italian seasoning
  • Baking soda

I have made this sauce for years and used to add dried seasonings, tasting as I went. I finally realized I can get a large container of organic Italian seasoning at Costco for under $5 and it works just great. So while this recipe calls for pre-made Italian seasoning, I have also included a link to a DIY recipe for those interested.

My secret weapon ingredient to keep this sugar-free is a pinch of baking soda. You’ve seen me use baking soda in my Crockpot Spaghetti Sauce, Healthy Sweet Tea Recipe and Whole30 Tomato Soup. Baking soda is perfect for neutralizing acidic flavors with no added sugar. 

Can you Freeze Pizza Sauce?

Yes, absolutely! In fact, I recommend it. I freeze the sauce in canning jars – 8 oz jam jars hold enough for four pizzas, and 4 oz mini jars will hold two pizza’s worth of sauce. For more details on jars I recommend, check out this Canning Supplies List.

How Long Will Sugar-Free Pizza Sauce Last in the Fridge?

You can keep your sauce in air-tight containers for up to a week in the fridge.

How to Use Homemade Pizza Sauce

Besides combining it with Whole Wheat Pizza Dough, it’s so good on tons of other things! Replace it for the marinara in Meatless Gluten-Free Lasagna, add it to Fried Halloumi and Bruschetta Zoodles, or this Whole30 Bruschetta Chicken recipe.

Like to dip appetizers into marinara? Of course, you do! Try it with Air Fryer Ravioli, Air Fryer Zucchini Chips, Cheesy Garlic Bread, or Air Fryer Artichoke Hearts.

Pro Tips/Recipe Notes

  • The baking soda will react with the acidity in the tomatoes and it will foam a bit and separate. Just stir gently for another few seconds and the sauce will come back together.
  • If you prefer a thinner sauce, add a bit of water or broth until it reaches your desired consistency.
  • If possible, let the sauce sit for 30-60 minutes before using. This will allow all the flavors to develop. It’s still usable right away but tastes better if it can sit.

  1. Love this sauce! I always try to have some in the freezer!

  2. Baking soda! Who knew that was the magic ingredient! I’ve tried so many homemade recipes and always go back to can cause it’s easier and they don’t have that acidic taste.
