This Keto Marinara Sauce has none of the sugar, additives, and thickeners you’ll find in store-bought versions. But this low-carb marinara sauce has heaps of flavor.

We dip our Cauliflower Tots in it, top our Chicken Parmigiana with it, and toss our vegetables in it. It’s one versatile keto tomato sauce. We even use our keto marina sauce as an ingredient for our Keto frypan pizza recipe.

    • Hi Miranda, you can certainly try Splenda. Just be aware that some Splenda products may spike insulin, we never use it.

      • In my opinion if you add sugar (or substitute) to your Marinara you might as well add ketchup instead of tomato paste.
        My Italian chef friend taught me to finely chops carrots and fries it in with the onions (after the onions and garlic are sautéed) before adding tomatoes… which is enough sweetness if you really want it, and then it’s 100% natural and nutritious + fiber.

        • Hi, Gail thank you for that. We’ll definitely give it a go. FYI all of the sweeteners we use are natural sweeteners.

    Wow this sauce is amazing! I used one can of diced tomatoes in place of some of the tomato puree as I like a little ‘chunk’ to my sauce. The flavors are awesome and it is so easy to throw together. This is going to be a staple on my menu. Thank you = )

  4. I just made this tonight! It is amazing and delicious! Thank you, I will be using it as a keto pizza sauce as well. We loved it, taste so much better than the jar. I used dried oregano and thyme 1tsp each and still came out fabulous!

    • Hi Elicia,

      I can’t see any reason why it couldn’t be canned – it also freezes well if you want to keep some on hand for a quick defrost.
