Slow Cooker Veggie Loaded Spaghetti Sauce
I have made this spaghetti sauce for years now and really it could not be simpler or healthier for you. No added oil, no added sugar, high-fructose corn syrup or anything bad for you. When you make your own spaghetti sauce you know exactly what is in it and in this one I load it up with healthy veggies. This recipe makes 4 quarts of spaghetti sauce which I use some right away the day I make it and then freeze the rest in quart sized Ziploc brand Twist ‘n Loc containers. And then I have sauce for whatever meal I want right in my freezer.
You can of course cut this recipe in half if you do not want to make so much. But I think it is a frugal and time-saving idea to make a big batch for later.
Also our family likes this sauce chunky. However, when my kids were littler they would balk at the big chunks of veggies so I would just run this in my blender to smooth it out some. Now that the kids are older they don’t mind the veggies. So feel free to blend it up to suit your texture needs. Either way it is still healthy and delicious! This recipe is vegetarian, vegan, low-fat, low sugar, low sodium, gluten-free and full of flavor!
Freezer Meal: Toss all your ingredients into 2 gallon sized zippered freezer bags, lay flat and freeze. When you are ready to cook, thaw bag slightly (leave out at room temp for 1 hour or microwave for 5 minutes) just enough to remove contents from the bag easily and put into your slow cooker. Adjust the cooking time by 1 – 2 hours to allow for thawing and the slightly more moisture that will be released from the frozen vegetables.

Nutrition

I am confused about the amount of crushed tomatoes. How much crushed tomatoes does this take?
Hi Virginia, I just looked at the recipe and can totally see where your confusion comes in. The recipe should have read “87 ounces crushed tomatoes) not 8 ounces! I have gone ahead and edited the recipe to reflect the proper number….87 ounces. Again, sorry about that and thanks for commenting and letting me know about the error.
What’s the amount of sodium in the sauce?
Hi LW. I just ran the nutrition data on this recipe and it contains 112mg of sodium per serving.
This sounds amazing!!! I would like to put ground beef in it while it cooks all day. Would I need to add any extra liquid like beef stock? I’m going to brown the beef before putting it in the crock pot with all the other ingredients. Thanks in advance!! 🙂
If you want to add pre-cooked ground beef to the recipe that will be just fine. There should be no need to add extra liquid.
