Notes
Nutrition
Serve this yummy entree with a side salad and some crusty French bread, and you have an elegant meal that would be just as great for serving to company as it is for serving to your family. This delicious recipe from the Alabama Hometown Cookbook is one you will want to add to your weekly meal plan.

Tips for Perfect Pasta Bake:
- Cook pasta al dente. It will continue to cook in the oven, so slightly undercooked pasta gives you the best texture.
- Use cooked chicken. Rotisserie chicken or leftover baked chicken works great and saves time.
- Drain spinach well. Press out any excess moisture to prevent your pasta bake from turning watery.
- Add extra cheese. Mix some into the sauce, then sprinkle more on top for an extra-gooey finish.
- Make ahead. Assemble the dish, cover, and refrigerate up to a day in advance – bake when ready to serve.

cooked or uncooked pasta?
In step 2, it says to prepare pasta according to package directions. So, the 8 ounces of pasta listed in the ingredients is uncooked. (After you cook it, it will weigh more than that, but you don’t need to worry about the weight.)
This was absolutely AMAZING with the following modifications. I used a 10oz bag of fresh spinach and sauteed it with a tsp of minced garlic and olive oil instead of using the frozen spinach. I also doubled the cream cheese and canned tomatoes. It came out perfect and my family was making audible moans as they ate this. This is going in our regular rotation. A new favorite!
I left a couple of things out of my last review and comments so let me start all over with my modifications. I sauteed the chopped onion with a tsp of garlic for a couple minutes then added a 10 oz bag of fresh spinach and sauteed until wilted. I doubled the cream cheese and the canned tomatoes and used whole wheat bow tie pasta and it was absolute PERFECTION. The added cream cheese and tomatoes also kept the leftovers from being dry the next day.
Do I need to drain the tomatoes for the chicken spinach pasta bake?
No, you don’t. Just add it in with everything else. 🙂
Awesome! Thank you!
