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.

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 1/4 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!


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.
