Easy Turkey Tetrazzini
Turkey tetrazzini is a turkey casserole recipe made with pasta, mushrooms, peas, and a creamy béchamel sauce, all topped off with a crunchy bread crumb topping.
Although the name tetrazzini might lead you to believe this is an Italian recipe, it’s actually an American dish supposedly named after the Italian opera singer Luisa Tetrazzini.
My family absolutely loves this recipe. They want me to make turkey more often so I can make it. I have made it with rotisserie chicken and it is equally as good.

- Add half of your butter to a large skillet along with the diced onion. Cook on medium-high until the onions are translucent.
- Then, add flour and whisk until a thick paste forms a roux. Slowly add chicken broth and then milk, whisking until smooth and creamy, to form your béchamel.
