I’ve been staring down a slow cooker tomato sauce recipe for ages, mentally adding it to my “to-make” list and then promptly forgetting about it. But with vegetables being zero points on Weight Watchers, it just made sense to whip up a big batch to save on points for all those future pasta dishes! Plus, there’s the added bonus of sneaking in some extra veggies – because let’s be honest, sometimes the love for veggies is a bit of a struggle (I totally get the love-hate relationship!). Homemade Zero Point Tomato Sauce turned out to be a total win! 
Super easy to throw together, it simmered away in the slow cooker and emerged as a delicious and flavorful sauce. I know there are a million and one pasta sauce recipes out there, but this one is definitely a keeper for me – it gets two big thumbs up! So, if you’re looking for a simple, veggie-packed sauce to elevate your pasta nights (or any other dish that needs a flavorful tomato base!), give this recipe a try!
Three reasons why you need to make this recipe!
You get pasta sauce full of nutrients and not sugar.
Unfortunately, many store bought pasta sauces are full of unnecessary sugar, and very little nutritional value. That’s why making your own is so helpful!
It tastes much better than store bought.
Most homemade recipes taste better than their store bought counterparts, and this one is no different. Plus, you get the added benefit of the wonderful aroma as it cooks away all day.
You can vary the veggies so they don’t go to waste.

Tips and Tricks for Making Homemade Zero Point Tomato Sauce:
- Store the sauce in mason jars. Once filled and sealed, cover the jars with at least 1-inch of water. Bring to a rolling boil and process for 15 minutes (20 minutes for altitudes 1000 to 6000 ft, 25 minutes above 6000 ft). Then turn off the heat and let the jars sit in the hot water for 5 minutes. Or you can use your own “canning” process if you have one.

I made this and it is delicious. I put into mason jars and straight to the freezer. I thaw it in the fridge and it has been fine. I also use for pizza sauce on Flatout thin flatbread crust. Delish!!
Hi Sally, so glad you are enjoying the sauce š
Hi! What size mason jar did you use?
I don’t have a crock pot- is it possible to make this on a stove top?
Yes I don’t see why not, I’d leave it on low heat for a few hours to give the veggies time to cook and soften
I canāt wait to try this! It sounds so yummy! This may be a silly question but I have never worked with mason jars before! Why do you have to do the boiling thing? Can mason jars be stored in the freezer? Thanks!
You need to seal the jars if you google “mason jar process” you might find other ways.. you can definitely freeze the sauce but you can just put in tupperware or freezer bags
Have you used fresh tomatoes instead of canned?
No, but I am sure you could š
Please tell me this sauce has flavor! I’ve tried other zero points sauce recipes on other sites and feel like they are really lacking flavor….
Hi Michelle, I think it does but we all have different taste buds, I say give it a go and you can always throw in extra seasonings/spices š
