Chicken Alfredo Penne Casserole

Imagine creamy, rich alfredo sauce drizzled over pasta cooked al dente. Are you craving it yet? But holding back from making up a batch tonight, because you want to avoid the heaping amounts of fat, cholesterol, and calories in traditional alfredo dishes? We’ve concocted an alfredo sauce in our kitchen that has all of the creamy goodness of the classix recipe, without the whopping fat and calories. This Chicken Alfredo Penne Casserole is a dish you can dig into without the guilt.

It’s amazing what a little creativity can to boost a recipe’s nutritional value and lower its fat, cholesterol, and calories. For this alfredo sauce, we’ve taken cauliflower and blended it until smooth with Parmesan cheese. No heavy cream required. Cauliflower has virtually no fat and is low in calories, and contains a hefty amount of fiber and antioxidants to boot! You’ll be amazed at how good this sauce tastes, and when you serve it to friends and family, they won’t believe that it’s not the traditional recipe!

We’ve taken pasta alfredo one step further by baking it as a casserole. Talk about the ultimate in comfort food! We’ve crumbled chicken or turkey sausage into this casserole to add lean protein, and just the right amount of mozzarella. Combining the sauce, pasta, cheese, and meat is easy to do and baking it up is a snap. Have this alfredo sauce on hand for an easy weeknight meal!

    This was absolutely amazing! I ate this at my desk on a cold, rainy day in Dallas and it went down really well! I’ve decided to make a batch of the Alfredo sauce for next time and for other recipes. Can you tell me whether it freezes well?

      Irene, You’re so right, this is perfect weather for this Alfredo Casserole. I haven’t frozen the alfredo yet but it should do fine. Just be sure to defrost
      in the fridge before heating in this or other dishes. So happy you enjoyed it! 🙂
