Reinventing Leftovers in a Cheesy Casserole

After a holiday, sometimes leftovers just need a little pizzazz! Turkey a la King is a favorite of mine, and now this easy, cheesy Turkey Tetrazzini is another great way to completely transform leftovers.

The recipe uses two cans of cream of mushroom soup as the shortcut ingredient, along with shredded cheese, to generously coat the pasta, turkey, and whatever mix-ins you choose (I used jarred pimentos, but it’s easily customizable). And if you don’t have turkey leftovers, cooked and chopped chicken works great.

I found the recipe in my grandma’s recipe book, typed out on her typewriter. It’s a classic comfort food casserole that the whole family will enjoy.

Enjoy! Kate

Ingredients

This is what I used, but see the “Variations” section for ideas on how to use what’s in your pantry/fridge already.

turkey, spaghetti, cream of mushroom soup, and other tetrazzini ingredients.

How to Make Turkey Tetrazzini with Cream of Mushroom Soup

  1. Cook the spaghetti according to package directions. While it’s cooking, whisk together the cream of mushroom soup, milk, onion, and pimentos.
  2. Add the cooked and drained spaghetti and half the cheese to the mushroom soup mixture, and toss to coat.
  3. Transfer to a casserole dish and top with the remaining cheese.
  4. Bake for 30 minutes at 350°F.

Variations

  • Use a different pasta shape, even a short pasta like macaroni, in place of the spaghetti.
  • Cream of chicken or cream of celery soup can be swapped for the cream of mushroom soup.
  • Don’t have pimentos? Try a diced bell pepper, a can of sliced mushrooms (drained), or a cup of frozen peas instead.
  • I used shredded mozzarella, but you can substitute a different shredded cheese such as colby jack, cheddar, or pepper jack. You can also dial back the shredded cheese a bit and add some parmesan on top.
  • No turkey? Two cups of chopped cooked chicken works as a substitute, or even canned tuna.
