FAQs

Is store-bought pizza sauces low-carb and keto-friendly?

In general, most store-bought pizza sauces include added sugars. There are some low-carb and keto pizza sauces available, but these options are pricey. 

Rao’s pizza sauce is my favorite store-bought pizza sauce made without sugar. It’s low carb, keto, and Whole30 compliant. The only issue is it cost between $4.50 – $5 for a 13-ounce jar. 

Yes, it’s possible to purchase low-carb pizza sauce from the store. However, it’s more cost-efficient to prepare homemade keto pizza sauce. If you want to use all organic ingredients or a particular tomato sauce brand, then cooking homemade allows you to have that control.

Can I freeze pizza sauce?

Yes, you can freeze pizza sauce. After the sauce has finished cooking, let it cool. After it’s cooled, freeze into 1 – 1 ½ cup portions to use on pizza or other recipes later on.

How to store pizza sauce?

After the pizza sauce is cooked and cooled then pour the sauce into an airtight glass container. I use one or two 16-ounce mason jars to store leftover sauce in. The sauce will keep in the refrigerator for up to 5 days. If you don’t use the pizza sauce within five days, then freeze.pizza sauce in a mason jar

Ingredients

low carb pizza sauce ingredients
  • Tomato sauce – Thrive Market and Muir Glen are both organic tomato sauce brands I love using.
  • Extra virgin olive oil – I use 2-3 tablespoons of olive oil.
  • Garlic – 2-3 medium to large garlic cloves will add delicious garlic flavor to the sauce. Although most of the time, when I make this sauce, I use about 4-5 cloves.
  • Oregano – traditional pizza sauce uses only oregano as a seasoning.

Substitutions

Use other seasonings. Dried basil and Italian seasoning are other seasonings to use in pizza sauce. 

Add butter. For a creamy, silky sauce, add 1-2 tablespoons of salted butter to the olive oil as you’re sauteing the garlic.  

Add crushed red pepper flakes. This gives the pizza sauce a spicy kick.

Add chopped mushrooms, or other vegetables, into the sauce. If you want to bulk up the pizza sauce’s nutrition, then saute mushrooms, zucchini, or eggplant before adding the garlic.

How to Make Keto Pizza Sauce

Like I said, this is the easiest homemade pizza sauce to prepare.

Start by chopping garlic and getting the rest of the ingredients together.

Then heat the olive oil over medium heat. Once the oil is hot, then add in the garlic. At this point, you’ll need to pay attention and move fast because garlic cooks quickly.

When the garlic starts to become fragrant and looks like it’s beginning to brown, then pour in the tomato sauce. Turn the heat down to low and give the sauce a few stirs until the garlic and sauce are combined. 

Then stir in the oregano.

Cook the sauce for 15 – 20 minutes or until it develops into a dark red color. 

Cooking the sauce for at least 15 minutes will help cook out the canned tomato taste and create a rich flavor.

This recipe creates about 3 cups of sauce. An individual serving size is two tablespoons. 

I use about ½ cup of sauce for 8-inch cauliflower pizza crusts. However, I use about 1 – 1 /2 cups of pizza sauce when making a sheet pan pizza. 

Leftover sauce can be store in the refrigerator for up to 5 days or frozen.

Use on your favorite pizza recipes.
