Crockpot Turkey Tetrazzini

Thanksgiving is such a wonderful meal to share with friends and family. We always make a spatchcock turkey, green beans with bacon, mini pecan pies or chocolate bourbon pecan pie.

And then, we usually have a lot of turkey leftovers.

Go beyond the basic leftover turkey sandwich and make this easy, hearty, oh so flavorful Crockpot Turkey Tetrazzini!

5 things you'll love about leftover turkey tetrazzini

I love this dish for so many reasons, but here are the top five reasons I think YOU will love this dish too:

1. The recipe calls for simple, wholesome ingredients. A lot of turkey tetrazzini recipes call for canned cream of mushroom soup, which gives the dish an artificial flavor. This recipe uses real heavy cream and cream cheese (sub your fave dairy-free alternatives if you are dairy-free), making it richer and much more flavorful.
   
2. You can use fresh or frozen vegetables. I use fresh mushrooms and frozen peas, because we always have frozen peas in the house. But you can also use frozen mushrooms.
   
3. It cooks in one pot. One pot meals are amazing for easy clean up!
   
4. No waste. This recipe makes the most of those turkey leftovers and transforms them into a whole delicious new dish!
   
5. It's a great freezer meal. You can make the entire dish, cool, and then freeze to reheat for a future dinner.

Kitchen tools and equipment

For this recipe, you just need a few basic kitchen tools:

Slow cooker - I use my 6-Quart MyTime Crockpot. This dish requires a 6-quart or larger slow cooker.

Knife and cutting board - to prep the ingredients.

Turkey - You'll need about 2 to 2-½ cups of cubed turkey meat. You can use dark meat and light meat - whatever you have leftover. You can use less than 2 cups but you may need to lower the amount of chicken broth a bit so that it doesn't end up too watery.

Mushrooms - Use baby bella (also known as cremini) mushrooms. They add the best flavor. But you can also use white mushrooms instead.

Onions and garlic - You'll need a half cup of finely chopped yellow onion and two cloves of minced garlic. Feel free to adjust these amounts according to your tastebuds.

Chicken broth - use homemade chicken stock or canned chicken broth. You can also use beef broth for a richer flavor, or vegetable broth for a lighter flavor.

Herbs - Dried or fresh thyme, basil, and oregano make this dish full of flavor throughout. You can also use 1-½ teaspoons of Italian Seasoning instead of the individual herbs.

Salt and pepper - Use kosher salt and freshly ground black pepper if you can. I usually also add a bit more of one or the other, or both, after the dish is fully cooked. Adjust your seasoning according to taste.

Spaghetti - You'll need to break the spaghetti in half before adding it to the Crockpot. This helps it cook a bit faster.

Cream - Use heavy cream or half and half.

Cream cheese - Be sure to cut the cream cheese into 1-inch cubes and distribute all around the Crockpot when you add it. This helps it cook faster and evenly, and also distributes the cream cheese better throughout the whole dish.

Peas - You can use fresh peas but I always use frozen peas. You can toss them in directly from the freezer, since they cook up quickly.

How to make crockpot turkey tetrazzini

Before beginning, make sure you chop up all of your ingredients and have everything ready to go.

1. To your Crockpot or other slow cooker, add the turkey meat, mushrooms, onions, garlic, thyme, oregano, basil, salt and pepper.

2. Then pour in the chicken broth and stir the ingredients so they are mostly submerged in the broth. Cover with the Crockpot lid.

3. Set your Crockpot on HIGH and cook for 2 hours.

4. After 2 hours, add the broken spaghetti and heavy cream. Stir ingredients together to submerge as much of the pasta under the liquid as possible. Some will stick up, and that's fine.

5. Add the cubed cream cheese on top, placed throughout the Crockpot. This helps it cook evenly. Cover.

6. Lower the heat level to LOW and set the timer for 30 minutes.

7. After 30 minutes, remove the cover, and stir the ingredients together. The pasta should be cooked al dente at this point. If it is not cooked enough to your liking: return the lid and cook for another 5 or 10 minutes.

Add the frozen peas, stir, and allow the ingredients to sit uncovered on LOW for 5 minutes, just until the peas have cooked through. Turn off the Crockpot and serve.

How to make it a freezer reheat meal

Turkey tetrazzini freezes and reheats beautifully!

To freeze: first allow the dish to cool completely. Then vacuum seal using your FoodSaver Multi-Use Food Preservation System, either into FoodSaver bags or, my favorite option: FoodSaver Preserve and Marinate Containers. These vacuum seal and stack neatly in the freezer.

Freeze turkey tetrazzini for up to one month in the freezer. Transfer to the refrigerator a day or two before you plan to reheat it.

To reheat: place turkey tetrazzini in an oven safe baking dish and cover with aluminum foil. Bake at 300°F for 30 minutes. Then remove the foil and bake for another 10 to 15 minutes, or until the dish is warmed up the whole way through.
