Tuscan chicken casserole tips
-
-
- Use your chicken leftovers: You can use your leftover chicken to make this Tuscan chicken casserole. Just bake in the oven for 15 or 20 minutes, depending on the amount of chicken used.
- Add a pinch of mustard powder or cayenne for an extra kick.
- If you want a crisp, crunchy topping, sprinkle your chicken casserole with breadcrumbs. Panko is wonderfully flaky and delicate, while crushed pork rind might be a good option for those following a low carb or keto diet.
- You can cut the chicken breasts into strips or pieces and mix them with the spinach and cream cheese mixture and seasoning for a “family-style” dinner that cooks quicker!
- Chop the sundried tomatoes if you don’t like big chunks.

This was really tasty. I substituted some chopped kale instead of the spinach, cause that's what I had in my fridge. I also realized that what I thought was a jar of sundried tomatoes in my pantry turned out to be chipotle peppers, so I threw in some cherry tomatoes instead and it was great. Looking forward to trying this next time with actual sundried tomatoes!

This recipe is fabulous!!! Chicken was tender, dried tomatoes on top gave it a savory flavor, and I even left it in the oven (on off) while I got the rest of dinner ready... definitely one to impress guests...thank you!

Outstanding!!! Restaurant quality! I did put a small amount of oil in the pan before cooking (9x13 glass pan) to keep it from sticking but otherwise followed the recipe as written. I don’t see how some have had dry chicken; mine was swimming in liquid. One issue I do have is that parsley is listed as an ingredient but was not used in the steps. I realize it would be chopped and sprinkled over (likely) but don’t list it if you don’t tell how to use it.
