Weight Watchers Recipe of the Day: Slow Cooker Lasagna Soup {Instant Pot Variation}
(202 calories | 4 4 3 myWW *SmartPoints value per serving)
I’ve been on a bit of an Italian food kick recently.
I just can’t seem to get enough of it.

WW Low Calorie Slow Cooker Lasagna Soup
So, when I came across this recipe for a lighter version Paula Deen’s Tastes Like Lasagna Soup on Spectacled Owl’s Roundup of 50 Weight Watchers Recipes for Weight Loss, it went right to the top of my “Recipes to Try” list.
The Skinny on Slow Cooker Lasagna Soup
I adapted Paula Deen’s Sons’ Take It Lighter recipe, turning it into an even lighter slow cooker lasagna soup.
The lighter recipe already was much skinnier than Paula’s original, with 404 fewer calories and 28 fewer grams of fat.
By using the microwave (affiliate link) and slow cooker, I was able to eliminate the need for additional oil altogether, shaving off about 1 WW Point per serving.

Easy Slow Cooker Lasagna Soup
I also used fewer lasagna noodles and added 1 cup chopped fresh mushrooms.
This slow cooker lasagna soup was even more delicious than I had hoped.
So much easier than lasagna, but with all the same delicious flavors, I’ll be making this easy lasagna soup again the next time I need an Italian food fix!
