Looking for a great recipe to take to…A dinner party? A friend who just had a baby? A potluck? Or just your own family dinner at home? Well, look no further because this Chicken Tetrazzini is a comforting classic that will please just about any hungry crowd. The creamy cheese sauce baked into lots of pasta, chicken, and veggies makes this casserole a well-rounded meal.
How to Make Chicken Tetrazzini
Place chicken in a large pot and cover with water. Bring to a boil and let chicken simmer until cooked through (at least an hour). Remove chicken (reserve broth) and let cool, then remove meat from the bone. Or just remove meat from a store-bought rotisserie chicken to use.
Bring the reserved broth to a boil. Cook the spaghetti in the broth until al dente. Set aside. If not using broth, cook the spaghetti in a large pot of boiling water.
Preheat oven to 350°F. Sauté the onion, green pepper, and mushrooms together until tender, about 5-10 minutes. Set aside.
In a saucepan over medium heat, melt the butter and whisk in the flour to make a roux. After 1-2 minutes, remove from heat and whisk in the milk. Return to low heat and simmer until the sauce starts to thicken, about 5 minutes. Stir the cheeses into the cream sauce until smooth.
In a large bowl, mix together the chicken, spaghetti, onion, peppers and mushrooms. Stir in the cheese sauce until well combined.
Pour into a lightly greased 13 x 9 x 2-inch glass baking dish and bake for 30 minutes or until starting to brown on top.
