All you need to make a keto-friendly pizza sauce at home are (details and quantities in the recipe cards at the bottom of the post):

  • Olive Oil
  • Crushed Garlic Cloves
  • Can of Crushed Tomatoes – check the ingredients listed on the box. You should only see tomatoes and evenly some preservatives or added salt but no sugar listed.
  • Tomato Puree – same here. Check the ingredient list and select a brand with no added sugar. I am using the Mutti brand, also known as a tomato passata.
  • Tomato Paste – most tomato pastes are sugar-free made of concentrated tomatoes but still, check the ingredients listed to select the best brand.
  • Salt
  • Pepper
  • Onion Powder
  • Italian Seasoning or Italian herbs – my seasoning doesn’t contain salt, so I added salt to the recipe. Italian seasonings combine oregano, marjoram, parsley, basil, and rosemary.
  • Keto Sweetener of Choice for a touch of sweetness. It’s optional, but I like a pinch of erythritol or allulose in my pizza sauce.


First, warm some olive oil in a non-stick saucepan and stir fry the garlic until fragrant.

Then, stir in the remaining ingredients: can crushed tomatoes, tomato puree, tomato paste, salt, pepper, onion powder, Italian herbs.

Stir, cover, and simmer for 10 minutes until the low-carb pizza sauce recipe is fragrant.

Remove from heat and stir a keto sweetener if desired.

Frequently Asked Questions

Can I Skip The Sugar-free Sweetener?

Absolutely yes! A traditional pizza sauce contains added sugar, and if you are used to this kind of sauce, you may want a sweet pizza sauce.

That’s why I love to add erythritol as a keto-friendly sweet touch to my keto pizza sauce. But, this is optional, and the recipe works very well without it.

Can I Use Fresh Tomatoes?

Yes, you can replace the can crushed tomatoes with fresh diced tomatoes if in season.

Can I Freeze The Pizza Sauce?

Yes, you can freeze the pizza sauce in plastic bags. First, fill the bag, remove as much air as possible, then place the sealed bags flat in the freezer.

The pizza sauce can be kept frozen for up to 6 months.
