Look no further than this slow cooker ziti pasta bake recipe! Using a slow cooker is a game changer when it comes to simplifying dinner.

I love that the slow cooker does all of the work for this recipe, including cooking the noodles.

How I Lightened It Up:
Store bought pasta sauce has points in it, even if it’s a light marinara sauce. By making your own sauce you can save points.
I used a 28 oz. can of crushed tomatoes, which is 0 points. Adding garlic powder, onion powder, oregano, basil, Italian seasoning, grated Parmesan, salt, and pepper helped transform it into a delicious marinara sauce.
As always, I used a food scale to weigh the noodles. Since I used 12 oz. of noodles, I wanted to ensure the points were accurate.
Topping the pasta dish with cheese is the star of the show in my eyes. I used part-skim mozzarella cheese to help keep the points low.
