Keto Pizza Sauce Ingredients

One of the best parts about this easy keto pizza sauce is that it’s made with just a few pantry staples. You probably already have everything you need:

  • Tomato Paste & Tomato Sauce – These are the base of the sauce. Make sure to check the labels and choose ones with no added sugar to keep the carbs low.
  • Dried Herbs – I love using oregano and basil for that classic pizza flavor. Feel free to add a pinch of thyme or Italian seasoning if you like.
  • Garlic Powder & Onion Powder – These add a great depth of flavor without needing fresh ingredients.
  • Salt & Pepper – Season to taste. You can also add a pinch of crushed red pepper flakes if you like a little heat.

How To Make Keto Pizza Sauce

This keto pizza sauce is so quick and easy, you’ll never need to buy the store-bought version again. Here’s how to make it:

  1. Gather all the ingredients – Make sure your tomato paste and sauce are unsweetened, and have your seasonings ready.
  2. Mix everything in a bowl – Add all the ingredients to a mixing bowl and whisk until smooth and well combined.
  3. Taste and adjust – Give it a quick taste and add more salt, pepper, or herbs if needed.
  4. Store or use right away – Transfer the sauce to a jar or airtight container. It’s ready to spread on your favorite low-carb pizza crust or use as a dip.

Yep, it’s that easy!

Tips and Variations For This Sugar-Free Keto Pizza Sauce Recipe

  • Let it rest – For the best flavor, let the sauce sit in the fridge for at least 30 minutes before using. This gives the herbs and spices time to blend together.
  • Make it spicy – Add a pinch of red pepper flakes or a dash of hot sauce if you like a little heat in your pizza sauce.
  • Thicker sauce option – If you prefer a thicker texture, simmer the sauce in a small saucepan over low heat for 10–15 minutes until it reaches your desired consistency.
  • Add a touch of sweetness – If your tomatoes are a bit too acidic, add a pinch of keto-friendly sweetener (like erythritol or allulose) to balance the flavor.
  • Boost the flavor – Stir in a tablespoon of olive oil or a splash of balsamic vinegar for a richer taste.
  • Make it extra garlicky – If you’re a garlic fan, feel free to add a minced fresh garlic clove for more depth.
  • Customize your herbs – Play around with seasonings like thyme, rosemary, or even a dash of smoked paprika for a twist on the classic flavor.
