2-for-1 Chicken Tetrazzini

A good friend shared a version of this recipe with me 35 years ago. I pay it forward by bringing the second casserole to friends when they are unable to cook. —Helen McPhee, Savoy, Illinois

    super easy and delicious. I was looking for something to use the rest of my rotisserie chicken and decided to try this. A nice change of pace and yummy!

    This was pretty good but I felt like it needed something. I made the full recipe and froze half of it for later. I omitted the mushrooms and subbed out the pimientos. Instead of pimientos, I cut up some sweet red pepper, then sauteed it with some onion after cooking the chicken. I think I didn't cut up enough though. I used about half a smallish onion, and half of a medium sized red pepper. Next time I'll try adding in other vegetables and see if that helps. I think this recipe could have also benefited from some garlic, maybe sauteed with the peppers and onions. I also think that the amount of chicken could be a little lower, maybe more like 3.5C. After baking the dish, I put it under the broiler for a couple of minutes to crisp up the grated parmesan, which worked out really well. Overall a good recipe, but I'll probably do some tweaks because it felt like it was missing something.

    Really good!! I didn't use the pimientos and added peas and used fresh mushrooms. This dish went over well for our group of friends and was easy to put together!!

    Very good. We left out the pimientos. I cut the recipe in half, I didn't need to freeze any. Rich, and filling. Easy to make.

    This was very good. I added peas and omitted the pimientos. I will definitely make this again. It was creamy and rich.

    I made this recipe without the pimientos, and added peas to it. I also bought two cooked chickens at the grocery store and used it in this recipe and it was great! I would definitely recommend this recipe. Very good, and the family loved it!!!

    I made this dish as directed except I did leave out the pimientos. It was wonderful! My husband who isn't much of a pasta person LOVED IT! He went back for seconds and thirds! haha
