Creating This Easy Chicken Tetrazzini Recipe

In the past 10 years, I’ve made many changes to the original cheesy chicken tetrazzini recipe that my mom used to make for our family growing up.

My remastered chicken tetrazzini casserole recipe nixes the over salted cream of chicken soup in favor of a homemade creamy chicken sauce created from a roux, chicken broth and whole milk.

My mom never added mushrooms to her version of this recipe, but seeking to increase the vegetables and nutrients I have been adding mushrooms for a while. I think they are a great addition. I also opted for half red and half green bell peppers to add color to this otherwise monotone dish.

Can I Substitute Leftover Turkey in this Chicken Tetrazzini?

Absolutely! This chicken tetrazzini recipe is a great one to use if you have a lot of leftover turkey after the holidays and want to make a comforting casserole.

Can This Recipe Be Doubled?

Chicken Tetrazzini is a great recipe to have in your files because it is so useful around the Holiday season.

For my family, this recipe bakes up perfectly in the Le Creuset 3 1/2 quart braiser, one of my favorite pans for delicious one-pot comfort foods, but it is easily doubled to feed a crowd (use a larger pan for a double recipe) and simple to put together when you have leftover roasted chicken or turkey.

What to Serve with Chicken Tetrazzini

I like to serve this cheesy chicken tetrazzini with a simple green side salad or some roasted veggies. There are plenty of veggies in the casserole itself, so I like to keep things easy!

Tips for Making Chicken Tetrazzini Casserole

  • When making the creamy sauce, be sure to constantly whisk the mixture to prevent any lumps from forming.
  • You’re welcome to add any extra veggies you have lying around to this cheesy chicken tetrazzini. The pasta and cheese hide lots of finely diced vegetables from picky eaters!
  • I recommend using spaghetti or fettuccine noodles in this recipe — anything long and thin will work.

I make this chicken stew recipe at least once a week. Here is the recipe from Food Network, although I will vary it sometimes by adding chopped spinach, extra tomatoes, or orzo.

I've also used a store-bought rotisserie chicken instead of poaching my own.

http://www.foodnetwork.com/recipes/giada-de-laurentiis/chicken-stew-recipe/index.html

Ingredients 2 tablespoons olive oil 2 stalks celery, cut into bite-size pieces 1 carrot, peeled, cut into bite-size pieces 1 small onion, chopped Salt and freshly ground black pepper 1 (14 1/2-ounce) can chopped tomatoes 1 (14-ounce) can low-salt chicken broth 1/2 cup fresh basil leaves, torn into pieces 1 tablespoon tomato paste 1 bay leaf 1/2 teaspoon dried thyme leaves 2 chicken breast with ribs (about 1 1/2 pounds total) 1 (15-ounce) can organic kidney beans, drained (rinsed if not organic) Serving suggestion: crusty bread Directions Heat the oil in a heavy 5 1/2-quart saucepan over medium heat. Add the celery, carrot, and onion. Saute the vegetables until the onion is translucent, about 5 minutes. Season with salt and pepper, to taste. Stir in the tomatoes with their juices, chicken broth, basil, tomato paste, bay leaf, and thyme. Add the chicken breasts; press to submerge.

Bring the cooking liquid to a simmer. Reduce the heat to medium-low and simmer gently uncovered until the chicken is almost cooked through, turning the chicken breasts over and stirring the mixture occasionally, about 25 minutes. Using tongs, transfer the chicken breasts to a work surface and cool for 5 minutes. Discard the bay leaf. Add the kidney beans to the pot and simmer until the liquid has reduced into a stew consistency, about 10 minutes.

Discard the skin and bones from the chicken breasts. Shred or cut the chicken into bite- size pieces. Return the chicken meat to the stew. Bring the stew just to a simmer. Season with salt and pepper, to taste.

Ladle the stew into serving bowls and serve with the bread.

I like this Spicy Coconut Chicken Casserole (from Martha) since I am not a fan of 'traditional' casseroles like my mother used to make!

Ingredients

* 1 tablespoon olive oil * 4 whole chicken legs (about 3 pounds total) * Coarse salt and ground pepper * 1 can (14.5 ounces) light coconut milk * 1 1/2 cups canned reduced-sodium chicken broth * 1 to 2 teaspoons Thai red curry paste * 1 cup jasmine rice * 2 red bell peppers (ribs and seeds removed), cut into 1-inch pieces * 8 ounces green beans (stem ends removed), cut into 1-inch lengths * 1/2 lemon, cut into wedges, for serving

Directions

1. In a 5-quart Dutch oven or heavy pot, heat oil over medium-high. Season chicken with salt and pepper. Working in two batches, cook chicken until browned, 6 to 8 minutes; transfer to a plate (chicken will cook more in step 2). 2. To pot, add coconut milk, broth, 1/2 cup water, and curry paste; bring to a boil, and stir in rice. Add chicken (with any juices), arranging pieces in a single layer. Cover, and reduce heat to medium-low. Cook, without stirring, until rice is almost tender, 15 minutes. 3. Scatter bell peppers and green beans on top of chicken mixture; cover, and cook until vegetables are crisp-tender, 8 to 10 minutes. Serve with lemon wedges on the side.

I am confused by the mention of bell peppers twice in the ingredient list... a total of 2 cups??? ( celery is listed twice too?)
