Great Keto Pizza is Possible on Your Low Carb Diet!

Following a low-carb or keto diet is easier than ever when you can enjoy great low carb pizza. The most popular keto friendly pizzas start with fathead dough, chicken pizza crust or a crispy cauliflower crust. All are great choices, so choosing a favorite depends on your preferred flavor and texture.

You'll be surprised to learn that the while today's keto pizza crusts are ultra low carb, it's the sauces and toppings you'll have to pay attention to. They may contain hidden sugars so make sure to read labels.

Carbs in Tomatoes

Tomatoes contain natural sugars and have a net carb count of 0.67 g per raw ounce. Tomato products, especially those which concentrate and thicken pureed tomatoes, are typically high in carbs. It’s common for popular canned/jarred tomato sauces and pizza sauce to add extra sugar to their recipes.

These hidden sugars often contribute to carb creep, causing stalls and weight gain for those on low carb keto diets. Luckily, my low carb sauce is so good you won’t even miss your old stand-by.

Keto Pizza Sauce

Several keto friendly pizza sauce recipes call for cooking-down fresh or canned whole tomatoes. And while I do that for pasta sauce, this method requires too much cooking time to make a quick pizza sauce.

Conversely, no-cook keto pizza sauce recipes mix a few dried seasonings with tomato paste and water. Yes, they are easy, but they lack the flavor of a cooked sauce.

My recipe takes the best parts of both methods, is easy and tastes great. While it's not ultra thick like store bought brands (Pizza Quick), it has less carbs and better ingredients. Here's how to make it:

  1. In a small pot, saute fresh chopped garlic in olive oil until softened and the raw smell cooks out.
  2. Add an 8 ounce can of tomato sauce to the pan and simmer with...
  3. Fresh chopped parsley, onion powder, dried basil, dried oregano, and red pepper flakes.
  4. Add a little sweetener because canned tomatoes are very acidic.
  5. Simmer about 5 minutes or until the sauce darkens a little and no longer smells raw.

Feel free to add chopped onion, fresh rosemary, dried marjoram, red pepper flakes or Parmesan cheese to make it your own.

NOTE: I had Contadina tomato sauce in the pantry but use your favorite brand. Just make sure that it doesn’t contain added sugars.

Other Keto Friendly Pizza Sauce Options

Some people can’t handle the acid in a tomato-based sauce anymore.* Still others want a new and exciting keto pizza flavor. Here are a few great keto pizza sauce options that will keep you loving your low carb pizza.

  • Alfredo sauce
  • Blue cheese dressing
  • Caesar dressing
  • Enchilada Sauce
  • Garlic and olive oil
  • Keto Barbecue Sauce
  • Pesto
  • Ranch dressing

TIP: Add a little baking soda to your tomato sauce to neutralize the acid. The amount of baking soda depends on the amount of sauce you make. Add ÂĽ teaspoon at a time until you notice the sauce is more mellow and no longer "bites". You can do this with your morning coffee, too. I add a pinch of baking soda to my coffee every morning!

What Can You Make with Sugar Free Pizza Sauce?

Spoon sugar free pizza over eggs for a quick-and-dirty Shakshuka (eggs-in-hell) recipe. It makes a great dipping sauce for cheesy keto breadsticks, mozzarella sticks or crispy fried eggplant . One of my favorite ways to use this sauce is for keto bagel pizzas. My kids love them as a snack!

Conclusion

It’s easy to make your own keto pizza sauce for your favorite low carb pizza crusts. It only takes a few minutes, you control the ingredients and it tastes great.

    Kim,
    This pizza sauce recipe is delicious. I’ve made a low carb keto pizza with it several times. It’s a no-fail recipe. I mince fresh garlic and lightly brown and use fresh parley instead of dried. I never have to use the full amount of keto sugar…just a little. It makes pizza sauce in a jar tastes terrible. It freezes well so you can make extra and have it ready for use; however, it’s quite quick and easy to whip up! Thank you for sharing your wonderful cooking skills and recipes! - Susan in Lafayette, Louisiana

    I love how easy this is and it is delicious. I just used half the sweetener and that was plenty and I love the flavor. It's great it can be frozen too so it can always be on hand. No need to buy pizza sauce anymore where I am looking to see what has the lowest carbs.

    Easy and ohhhh so tasty. Yummmmy... I used 2 cloves of garlic, dried parsley (didn't have fresh) and only 1 teaspoon of granulated monk fruit (my preference for sweetener). Froze the leftover sauce. Made my first keto pizza today, it was delicious. This recipe will be stored and shared. Very tasty sauce, try it you won't be disappointed. THANK YOU for this easy, quick and yummy pizza sauce.

    Would Stevia work in this for low carb sugar?

      If that's what you are used to, then go for it. I prefer stevia glycerite because it is MUCH less bitter than other stevia brands and forms, but use what you have. -Kim

          I would go drop by drop to taste. Some people (super-tasters) don't need as much as others. I really love using stevia glycerite to augment my other sweeteners. -Kim

      Hi Jacqueline. You will love this on the fathead pizza doughs or my cauliflower pizza crust (which is actually crispy!). Being able to whip up a pizza in less time than waiting for delivery is a game changer. I have also frozen extra dough and pre-cooked crusts. This pizza sauce recipe is easy enough to customize to your tastes. Enjoy! -Kim

      Hi Kim.

      Am I able to Use another brand name tomato sauce if I can’t find Contadina. Would you have any suggestions.

        You can use whatever you can find, Rosie. Just find one that has the least amount of carbs per an equal serving. You can use an already "flavored" one or plain. -Kim

    If tomato sauce has added sugar why not use tomato paste? Thats what I used and added all your suggestions with a half canvof wayer and it turned out great!

      Hi Cynthia. Tomato paste is fine, but since it is a concentrated product the sugars in the paste are concentrated, too. There are many recipes for pizza sauce with tomato paste and water. I feel this recipe is fresher in taste and I like the texture as it is more like a thick homemade sauce vs a paste-like product. -Kim

    Thanks for this simple pizza sauce recipe. I hate the store bought ones but somehow never got around to making the sauce myself.

    Would it be possible to convert to a large batch recipe and preserve by canning using traditional hot water bath methods? If so, would you exponentially convert measurements 1:1 as is in the original recipe?

      I'm sure you can, Andy. Make the small batch recipe first to make sure you like it as is - you might prefer more garlic or to add fresh basil or whatever per your tastes. The recipe card has a scaler that will scale the ingredients for you. -Kim
