Transform Thanksgiving Leftovers into Slow Cooker Turkey Tetrazzini

Once Thanksgiving is over, it’s time to get creative in the kitchen and brainstorm different ways to use up all of those leftovers. While my go-to is simply turkey on white bread with way too much mayonnaise and cracked black pepper, you can only eat so many turkey sandwiches (that’s not true, I could eat them everyday). But for those of you who want something a little more exciting, try adding leftover turkey to soups, like Turkey Tortilla Soup, or using it as an add-on to your favorite fall salad.

If you are feeding the family or still have out-of-town guests staying with you, use up all of your turkey leftovers in Slow Cooker Turkey Tetrazzini.

The Test Kitchen decided to make this tetrazzini in the Hamilton Beach® Professional Sous Vide and 6QT Slow Cooker (but you could adapt this to whatever shape slow cooker you have) because the rectangular crock mimics a casserole dish.

This classic casserole is cooked on slow cooker mode and has all the usual suspects. The combination of pasta, turkey, and a creamy sauce makes for classic comfort food. The roasted red peppers and bright green peas add pops of color while the breadcrumbs on top add the crust you crave on a traditional casserole.

Skip the white bread and toss your turkey into the slow cooker. Turkey tetrazzini is sure to become one of your go-to recipes post-Thanksgiving.
