Rotisserie Chicken Spaghetti Casserole

Recipe by HeatherFeather

This is one of those casseroles with many versions. What makes mine somewhat different is the use of rotisserie chicken, there are also no tomatoes, as well as some other slight differences. This is a kid pleaser and makes a nice potluck dish. If you can't find the chicken soup with herbs in it, just use regular Cream of Chicken and add a bit of dried herbs (perhaps 1 tsp of mixed dried green herbs). I used the reduced sodium versions of the soup because otherwise the sauce base can be too heavy and salty. If you dislike cream of mushroom, you may use a different flavor of "cream of..." soup however.

I was pleasantly surprised that my family really enjoyed this dish. I put too much garlic powder for my tastes, but they ate it 2 nights in a row. This recipe makes a MASSIVE amount! I used 2 small cans of mushrooms since I didn't have fresh on hand. I also used yellow onions and I added a few stalks of chopped celery. And since I didn't have the Velveeta cheese, I tore up American Cheese slices and also added a little bit of shredded mozzarella cheese. The casserole stayed in the oven for nearly an hour - perfect for an evening when I don't know what time to have dinner ready. I would make this again, but for my own tastes would omit the garlic powder and use fresh garlic instead.
