Keto Pizza and Low Carb Marinara Sauce

I created my first keto pizza tonight.  My own recipe - a twist on fathead dough was the base and it was AMAZING.    I mean UHHHH-MAZING!

Making your own keto pizza sauce can make all the difference.  Traditional pizza sauces are rather high in carbs.

So, off I went to create something....  Something with a little kick but not with an overwhelming non-pizza-sauce flavor.  But here's the thing, the lasagna marinara sauce that I had already created can really double as both.  It is amazingly versatile.

Sauce and tomatoes are tough, though.  While I don't believe we need to stay away from tomatoes, I do think we need to be mindful of the carb count in them no matter how we eat them. 

This keto pizza sauce turned out to be quite versatile.  I'm thinking it might even be my sauce of choice to dip this keto flatbread into.  Hmm.... Why not?

Without further ado, let's dive into the flavors of choice for this sauce.

Low Carb Pizza Sauce Flavors

Fire Roasted Tomatoes - if you want to spice up tomatoes, this is the way to do it.  AND you can buy it!

This just adds a, well, fire flavor.  Not too spicy, but just enough!

Italian Seasoning - I chose Italian Seasoning because this is keto PIZZA SAUCE!  And because Italian Seasoning just makes everything taste better, right?

Garlic and Onion - What don't you use these spices with?  Anyone?

What Do You Need to Make This Keto Pizza Sauce

Food Processor - I use my Ninja to chop up the tomato chunks. 

See, I'm one of those weird people who LOVES a good pizza sauce or marinara sauce, but I cannot stand tomatoes.  I refuse to eat them whole or even eat chunks.

So, for all those out there like me, you'll be happy to know this sauce has NO chunks!

Sauce/Frying Pan - This sauce calls for heating it up to blend the flavors.  I use a frying pan so it is wide, but you can use a regular saucepan as well. 

Mason Jars - if you plan to store any of this sauce, it keeps very well in mason jars!

Is This Keto Pizza Sauce High in Carbs?

As I said above, tomato-based sauces can be high in carbs.  Even some keto ones. The serving size for this is 1/4 cup and it is about 1.8 net carbs.  Which really is not too bad.  

It makes about 2 cups, so there are 8 servings.

Another low carb and delicious sauce is this authentic Neapolitan pizza sauce and it is a no-cook sauce which is a bonus!

    How do you steralise your mason pot and lids so that the sauce won’t turn?
    You see i made a batch of spaghetti sauce and it all went bad

    1. Hi there! This is not a canning recipe or one that is meant to store long term. I use mason jars (and store in the fridge) if I have leftovers and will generally use it up within a week. I have not tried to keep it for longer.

    2. I often make tomato based sauces and put it in freezer bags. Lay each bag flat in the freezer and freeze. Once frozen you can stand them upright for slim storage. I do this with meat added for some recipes as well. Always tastes great when using. Just portion each bag to what you would use for a recipe and put it in the fridge the night before using.

  2. This was great. I’m using it for other things also. Was very good with burger added to it for a quick, fast, and easy pasta sauce.

  3. Can also be frozen in the canning jars. Just be sure to leave about 3/4 inch at top because it will expand when frozen.
