Isn’t it funny the things that excite us when we become adults? I finally got a nice chest freezer to store all of my frozen foods and Costco finds. I was so excited to get it and put it in my basement it felt like Christmas. My boys are getting to an age where they are always hungry and eating, and our freezer upstairs just wasn’t going to cut it anymore.

I love to make a big casserole and freeze the other half for later. Now I have my own little section in my chest freezer with all of my frozen meals. Does anyone else get excited over little things like this? Maybe I am the only one out there to get so excited about a chest freezer. 🙂

This casserole made a big 9×13 batch and I was able to divide it into two and freeze the other half for later. And to tell you the honest truth, I think this is one of the best casseroles that I have ever had.

Not only is it made with my famous and amazing alfredo sauce, it has the added flavor of pesto. Two of my favorite things combined to make this casserole creamy, flavorful, and delicious. It also had spinach and crushed tomatoes hidden throughout. This casserole is simple but so delicious!

Oh and don’t forget the ooey gooey cheese inside with each and every bite. This casserole just keeps getting better. I loved how it is topped with bread crumbs adding a crunchy texture to the top. It is seriously awesome!

This became an instant family favorite and I know that it will be a hit at the dinner table!

  1. I love freezing foods for future use. this recipe looks worthy of trying. I always purchase fresh vegetables, onions, peppers, tomatoes, celery, chop and blanche them and freeze to take out for recipes, soups, casseroles;
    even better when buying fir a great sale price to freeze

  2. This was such a great recipe. I’m glad I tried it! I did add 3 cups of heavy cream instead of 2 cups and my jar of pesto was 6.5 ounces instead of 8. It was delicious.

  3. This was fantastic! I subbed rotini for the penne and diced tomatoes instead of crushed tomatoes.
