Ingredients You’ll Need

This section explains how to choose the best ingredients for sugar-free pizza sauce, what each one does in the recipe, and substitution options. For measurements, see the recipe card below.

Olive Oil – For the best tasting sauce, use a high quality variety. I recommend extra-virgin. Avocado oil will also work if that’s what you have, but the flavor is better with EVOO.Tomato Paste – Adds rich tomato flavor for a classic sauce.Dried Herbs – Oregano, basil, and marjoram are traditional herbs in this keto sauce for pizza. However, you could substitute an equivalent amount of homemade Italian seasoning if needed.Dried Spices – Garlic powder, onion powder, and fennel seed. You can also add a sprinkle of red pepper flakes if you like.Salt & PepperBalsamic Vinegar – Adds subtle sweetness and body to this sauce. You could skip it, or add Powdered Besti (which dissolves easily, unlike other sweeteners) if you like more sweetness.Water – To thin out the sauce.
