Tetrazzini is one of the South's favorite casserole recipes. It's easy, comforting, and kid-friendly. At the base of a classic tetrazzini recipe is turkey, chicken, or seafood, sliced mushrooms, pasta, cream sauce, cheese, and some kind of topping—from these ingredients there are many variations and additions, making this dish flexible, popular, and delicious.

Our Favorite Turkey Tetrazzini

Our favorite Turkey Tetrazzini recipe requires minimal effort that yields big rewards. This recipe is easier than ever before thanks to convenience products like jarred Alfredo, cream of mushroom soup, packaged sliced mushrooms, pre-shredded cheeses, and seasoned croutons. Use up that leftover turkey from your Thanksgiving feast—other than that, cooking thin spaghetti is the only prep that involves your stovetop. This crowd-pleasing recipe makes eight hearty servings in an 11-by-15-inch baking dish.

Blend and Top with a Crispy, Cheesy Crust

Simply whisk together the soup, milk, and Alfredo sauce. Stir in chopped turkey, cooked thin spaghetti, peas, mushrooms, Swiss cheese, and ½ cup Parmesan cheese. Pour everything into a lightly greased baking dish before topping with crushed croutons, paprika, and remaining Parmesan cheese.

Bake for 45 Minutes

The casserole will need to bake covered for about 30 minutes at 375 degrees. Uncover and bake another 15 minutes until it's golden brown, bubbly, and absolutely delicious. Wait 10 minutes before letting your hungry family dig in.

No Turkey? No Problem

We love whipping together this tetrazzini with the last of the leftover Thanksgiving turkey but, of course, this casserole is too good to enjoy just once a year. So, don't worry if you don't have leftover turkey on hand. You can substitute cooked chicken or ham for an equally delicious dish. To speed things up, grab a rotisserie chicken from the deli section at your favorite grocery store.

Sneak in Those Veggies

For little ones who have a hard time eating their veggies, this casserole is a winner. They might finally eat peas when they're scattered throughout this warm and comforting casserole. The creamy sauce and cheesy topping will work wonders for picky eaters. Once you master this classic, feel free to add in some of your family's favorite ingredients for a spin all your own.

Divide and Make Ahead

This recipe can be divided into two 11 by 7-inch baking dishes, a helpful meal-prep solution for when you want to freeze one of the two casseroles for a dinner down the road. To make ahead: assemble and freeze for up to one month; when ready to eat, thaw overnight in the refrigerator; cover and bake at 350 F for 40 minutes; and to finish, uncover and bake 15 more minutes until cheese is melted and bubbly.

More Tetrazzini Recipes

If you want to try a different spin on this one-dish casserole, we have several recipes to explore. In our Classic Chicken Tetrazzini recipe, the cheese sauce is made from scratch, and once assembled, it's topped with slivered almonds and parmesan—even with the handmade sauce, it can be made in under an hour. For fewer steps, this similar almond-topped Chicken Tetrazzini recipe uses convenience items. To bump up chicken tetrazzini's flavor and nutrition, add prosciutto and peas. Finally, for an updated take, our New Turkey Tetrazzini includes loads of spinach, cremini mushrooms, and a garlic-herb cheese sauce.
