🥫 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.
