Instructions

  2. Place the tomatoes in boiling water for 30-60 seconds.
  3. Gently remove the skin.
  4. Cut the tomatoes into quarters and place in a microwave safe bowl.

Your low carb pizza sauce is ready! It can be used immediately or canned for later use. If you want to spic it up, sprinkle in some red pepper flakes.

What pizza sauce is keto

You can find a lot of keto friendly pasta sauces at the store these days. However, pizza sauces may be harder to find.

Rao’s pizza sauce has just 3 net carbs per ¼ cup with no added sugar. It’s pretty common to find at the store, too!

You could use a keto marinara, but it will be thinner than this low carb pizza sauce. I personally don’t like substituting pasta sauces on my pizza.

That’s why I usually make my own keto pizza sauce. I know exactly what ingredients are going into it, and I can make extra for future use!

Carbs in tomatoes

Tomatoes are a low sugar fruit, so you can enjoy them in moderation on keto.

A medium tomato is going to have about 4.8 total carbs and 1.5 grams of fiber. So your average tomato will have about 3.3 net carbs.

This recipe calls for 4 pounds of tomatoes and makes 16 servings. At that size, each serving will only have about 3 net carbs.
