Use Leftover Turkey

Raise your hand if you have leftover Thanksgiving turkey? My hand is up. Turkey tetrazzini is a ‘I have leftover Thanksgiving turkey’ recipe. While there’s no universal standard recipe for turkey tetrazzini (hence why no two versions are the same), the one thing that’s universal is that is uses cooked turkey.  I don’t know about you but I don’t usually have leftover, cooked turkey in my frig, usually only on holidays. If you don’t have turkey, you can substitute cooked chicken.

Low-Carb Turkey Tetrazzini

Traditionally, turkey tetrazzini is made by baking the leftover turkey with mushrooms and pasta in a butter/cream sauce.  To make this version low-carb, I used spaghetti squash in place of the pasta and a homemade cheese sauce.  The spaghetti squash needs to be cooked beforehand. The fastest way to cook spaghetti squash is to pierce it all over with a fork and then pop it in the microwave. It’ll be done in less than 10 minutes depending on the size of your squash. You can also bake your spaghetti squash or even cook it in the slow cooker.

Low-Carb Sauce

No canned ‘cream of soups’ here. Rather than use a can of processed cream of mushroom soup, the sauce for this turkey tetrazzini is a homemade sauce. It took me a while to get this cheesy sauce right. It’s a combination of butter, broth, whipping cream (heavy cream works too), and mozzarella cheese. Xanthan gum is added as a thickening agent. You can omit it or use your preferred thickening agent like arrowroot flour/starch. If you have a particular cream sauce you like, you can substitute it for my homemade one.

Optional Steps

Adding More Cheese

When the tetrazzini is done cooking, add 1 cup of shredded mozzarella cheese on top and cook an additional 15-30 minutes or until the cheese is melted. While this is optional, think the dish is better with the additional cheese added.

Oven Instructions

I don’t provide baking instructions too often because this is a page mainly dedicated to healthy slow cooker & electric pressure cooker (Instant Pot) recipes. However this recipe is a good one for baking too. Preheat your oven to 375. Follow the slow cooker instructions but instead of adding the food to the slow cooker, add it to a greased casserole dish.  Bake uncovered 25-30 minutes.
