Skinny Alfredo, Tuna Noodle Casserole

I’m bringing back an oldie but goodie. It’s a comfort food classic with a twist, super skinny with an Italian flair! And it comes together very simply by using a jarred light Alfredo sauce and whole-grain noodles. So delicious and very satisfying. Each serving has 184 calories and 5 grams of fat.

You can find reduced-fat Alfredo sauce in most supermarkets in the pasta sauce aisle. Classico and Bertolli both make one. I used Classico to calculate the skinny facts.

  1. Another winner to add to my collection
    I usually add peas but decided to serve the peas on the side. It was great as is. My first time using Alfredo sauce, where have i been? Used Classico 4 cheese, 45. Calories in 1/4 cup. It didn’t say light on the label, but I assumed it was the lowest calorie they make. Thanks for the delicious recipe

  2. Fantastic feedback, Jackie. Thanks so much. Yes jarred Alfredo sauce is a wonderful find. That’s why I’ve shared so many recipes using it. And you’re right, most of the brands of jarred Alfredo sauce are Light even when the jat doesn’t say it.
    My very best,

  3. Thank you, Robin! I agree, the alfredo sauce works amazingly in this casserole.
    All the best,
