WW Recipe of the Day: Low Sugar Slow Cooker Marinara Sauce

Marinara sauce is one of my favorite ingredients to have on hand for quick and easy meals.

When you don’t have the time to cook tomato sauce from scratch, jarred marinara sauce is life-saver. I always have a jar or two in the pantry. But I’ve learned to read the ingredient and nutritional labels to avoid unnecessary extra sugar, fat and calories.

As a Lifetime Weight Watcher, I am always on the lookout for a brand that tastes good for the fewest Points and a reasonable price. I like Classico Tomato & Basil Pasta Sauce. A good value, a jar usually costs $3 or less and each 1/2 cup serving has just 2 WW Points.

Making homemade marinara is almost as easy as jarred, especially when you use your slow cooker. And because it has much less sugar, each serving of this easy healthy marinara has just 1 WW Point.

This simple slow cooker marinara sauce is perfect for busy days since the longer it simmers, the better it is.

I used my new favorite slow cooker, my Instant Pot (affiliate link), to whip up a batch recently. I love that I can saute and slow cook all in the same pot.

The leftovers can be portioned out and frozen for future quick and easy meals.

  1. Anytime I make marinara sauce, I substitute a shredded carrot for sugar. The natural sweetness is just right and doesnโ€™t add any points.

  2. I signed up for your recipes some time ago, and even paid for my membership, however I never received anything from you.

    1. Hi Harriet, I don’t have a paid membership here on Simple Nourished Living, just a signup for free emails with recipes and other weight loss tips & hints. I sell eBooks but they are a one time purchase that you download. Hope this helps. Warmly, Martha

  3. Martha., you’ve shared some really yummy marinara recipes. Thanks so much for including my Simple Summertime Fresh Roasted Marinara Sauce on your list!
