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 in a glass bowl

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.

  1. I loved how quick this sauce was to whip up and the texture came out smooth and rich without any fuss. It clung perfectly to the fathead pizza crust and didn’t make it soggy. Definitely my go-to sauce now.

  2. I liked how simple the steps were especially for someone new to making sauces. The garlic flavor was strong in a good way and made my whole kitchen smell amazing. It also reheated really well the next day which was a nice bonus.

  3. Blending the tomatoes right before cooking made a big difference in the richness of the sauce. I used a blender for about 10 seconds and the texture came out really smooth. The low heat at the beginning helped keep the garlic from burning, and the olive oil gave the sauce a nice glossy finish. I cooked it for around 12 minutes and loved how it thickened just enough without reducing too much volume. The balance between the tomatoes and the olive oil was perfect for a base sauce without needing sweeteners.

  4. Can I use diced tomatoes instead of whole tomatoes for this keto pizza sauce, or will that change the texture or flavor when it’s blended in step 1?

  6. I really liked how blending the whole tomatoes right before cooking gave the sauce such a fresh and vibrant flavor. The olive oil carried the garlic aroma beautifully after that short sauté, and it really came through in the final sauce. I simmered for the full 15 minutes and got a nice thick consistency that didn’t make my pizza soggy. I might add some basil or oregano next time for an herbier kick.

  7. I was impressed with how quickly this sauce came together using just a few simple ingredients. The 28 ounce can of whole tomatoes had a really fresh taste after blending and didn’t need any extra seasoning beyond salt and pepper. Cooking it for about 13 minutes gave me the perfect thick consistency without over-reducing. I loved that the olive oil added a silky texture and helped the sauce cling to the crust beautifully. Definitely a great staple for keto pizza nights.
