I came up with this recipe because I needed something quick for friends who dropped by. It's very easy and takes only 35 minutes to bake. Enjoy!

Blue Ribbon Recipe

Casseroles were created for back-to-school season. This creamy chicken Alfredo casserole is super yummy and comes together very quickly. It has a nice flavor and is super creamy. We loved the addition of garlic and Parmesan to the jarred Alfredo sauce. Peas give the casserole a pop of sweetness. Buttery Ritz crackers on top get all toasty while this bakes. It's a wonderful meal on a busy weeknight.
