Keto Spaghetti Sauce

As our Homemade Keto Spaghetti has been developed, one might need some sauces to complement them. And Bolognese Sauce should not be the only one. 

Together with white Alfredo and Carbonara, we for sure needed something additional, where tomatoes are involved. 

Who wants to keep buying expensive Rao’s Keto Marinara Sauce?

Maybe from time to time, but wouldn’t it be awesome if you can make your own Marinara Sauce with only a few ingredients, the same carb intake, and in no time? 

Keto Meal Plan

Our Marinara Sauce goes with so many dishes, that having it as a part of your Meal Plan is a must. 

It is extra easy to store and you can use it as a dip with our Twisted Bacon, French Fries, or Italian Breadsticks.

You can top up our Rainbow Pizza or spread it onto Fathead Bacon Pizza.  

And of course, use it on any of the Low Carb and Keto Pasta Noodles Variations

Or have a full dinner meal with homemade pasta and convert it all into a perfect Italian Keto Pasta Marinara.

What is Marinara Sauce?

Marinara Sauce is an Italian Tomato sauce also called “Sugo Finto” made with onion, garlic, and spices such as oregano and basil. 

In some instances, Olives or capers are added. 

Our version goes for a typical traditional way.

Have you heard of Rao’s Marinara Sauce?

Perfect Homemade Italian Low Carb Tomato Sauce, which is store-bought and fits fully with our Keto Lifestyle. 

But

Wanna Save Money? 

Choose the cost-effective way and make your own Sugar-Free Marinara Sauce with us. 

The carb intake per serving and ingredients are exactly the same as our homemade keto pasta sauce recipe, you can whip it up in no time. 

Can I eat Marinara Sauce on Keto?

Even though tomatoes are slightly higher in carbs, if you are using them properly and following the servings, you can perfectly add your Marinara Sauce into a Keto Diet.

Can I use Fresh Tomatoes instead of canned in Marinara Sauce?

Yes, you can certainly use fresh tomatoes instead of canned in this sugar-free tomato sauce, but blanch them and peel the skin if you would like to have that smooth consistency.

On the other side, the skin adds more fiber as well as antioxidants to your meal and if you use an Immersion blender, it should smooth it out fully.

Low Carb Marinara ingredients needed

Second Step: Brown Onions

First, let us start browning onions. I have used Extra Virgin Olive Oil, but you can as well use Avocado oil if you wish, which gives an additional flavor to this Keto Tomato Sauce.

Third Step: Herbs & Garlic

Once the onions are browned, add freshly chopped herbs and Garlic. 

Let it cook on medium heat for a minute or so, to get all of the flavors from basil, oregano as well as garlic out into the sauce.

Tips and tricks

Tomatoes – you can use Fresh tomatoes instead of Canned if you wish. I would suggest blanching them and peel the skin if you would like to have that smooth consistency. On the other side, the skin adds more fiber as well as antioxidants to your meal and if you use an Immersion blender, it should smooth it out fully.

Oil – Avocado Oil instead of Extra Virgin Olive Oil works perfectly as well

Herbs – in case you do not have fresh oregano, you can add any Italian fresh herbs you have available.

FREQUENTLY ASKED QUESTIONS AND ANSWERS

How do I smooth the sauce fully?

As you see on the video and images, I have not blended the sauce, because that is how our family likes it.

But just in case you would like to smooth the whole sauce, you can easily do that with an Immersion blender or just place the whole sauce into your Big Blender and blend for a few minutes to get that perfectly smooth consistency. 

How do you store Marinara Sauce?

To store Marinara sauce is extra easy same as BBQ sauce

As this Low Carb Pasta Sauce is perfect for your Meal Preps, it is great to double the recipe and store it in smaller mason jars, which you can use as portions. 

Alternatively, the big Mason Jar of this Sugar-Free Spaghetti Sauce can be perfectly stored for the whole family in the refrigerator for up to 3-4 days. 

Anything longer, I would suggest freezing. 

Can you freeze Marinara Sauce?

You can certainly freeze Low Carb Marinara sauce and that is exactly what I do. 

I fill few Mason Jars with it and have them ready whenever we are in a hurry or have no time in the evening to cook.
