Low Carb Pizza Sauce

Low Carb Keto Pizza Sauce
When it comes to pizza sauce, I used to just use a tomato sauce with the lowest carb count possible for our low carb pizzas. There are a couple at my local supermarket that have about 3 grams of carbohydrates per ¼ cup of sauce; however, they contain added sugar. On top of that, canned tomato sauce is completely bland. It has zilch authentic Italian flavor.

In order to find a pizza sauce that was both low in carbohydrates and flavorful, I decided to make my own sauce. But it had to be easy, of course. If I get the urge to make pizza on the fly, I want a sauce that’s quick to put together.

How to make homemade keto pizza sauce?

This is a simple pizza sauce recipe with just four ingredients :

  • olive oil
  • garlic
  • canned whole tomatoes
  • salt

After puréeing the tomatoes in a food processor, the crushed tomatoes are added to a saucepan of fragrant, sautéed garlic in olive oil and cooked over medium heat for up to 15 minutes. The sauce will thicken as it cooks. Salt is added at the end for that Italian zing to the tomato based pizza sauce.

Adding four tablespoons of olive oil to this red pizza sauce helps to bring up the fat count in this keto recipe. Canned tomato sauce doesn’t contain any fat. This keto pizza sauce has 2.3 grams per tablespoon of sauce. The olive oil also provides more flavor to the sauce.

Besides being easy to make, keto pizza sauce makes about 12 servings (serving size is 2 tablespoons) which is enough for six to twelve pizzas, depending on how much red sauce you like to add.

  • Canned vs fresh tomatoes to make pizza sauce

    Canned tomatoes are a great option for this red pizza sauce when fresh tomatoes are in short supply during the off season. You don’t want to use store bought, fresh tomatoes during the winter season as they will not be as flavorful as canned tomatoes. Some of my favorite brands of canned whole peeled tomatoes are Muir Glen and Hunt’s Whole Plum Tomatoes.

    If you grow your own tomatoes and they are prime for the picking, go ahead and use fresh tomatoes. I would roast them first with some olive oil and salt. Then peel the tomatoes and pulse in a food processor.

    Canned tomatoes come in different varieties - diced, stewed, crushed and whole

    Canned whole tomatoes are sold peeled in their own juice or puree. They are the highest quality of canned tomato product since the tomato is still intact and now broken down, which is when the flavor can start to disappear.

    Diced tomatoes are tomatoes cut up and packaged in their own juice. As long as you are going to puree the diced tomatoes, you can substitute them for the whole tomatoes in this recipe for pizza sauce. However, canned diced tomatoes are treated with calcium chloride to preserve their firmness so it can be difficult for them to break down during the cooking process.

    Crushed tomatoes are a mixture of pureed and chunks of tomatoes. There are variations of chunk sizes between brands.

    Stewed tomatoes are cooked and canned with sugar and other seasonings. Avoid using stewed tomatoes because of the higher carbohydrate content.

    For this red pizza sauce recipe, you want to buy canned whole tomatoes as they offer the most flavor for your sauce.

    Add seasonings to your low carb pizza sauce

    You can add other seasonings to the pizza sauce! Try adding basil, oregano, crushed red pepper flakes or other Italian seasonings to the sauce.

    Storing your keto pizza sauce

    Extra sauce can be stored in the refrigerator for up to five days or the freezer for up to three months. This makes it a convenient way to always have keto pizza sauce on hand when your pizza cravings hit.
