How to Make Crockpot Turkey Tetrazzini
Get ready to experience the magic of a truly simple crockpot turkey tetrazzini recipe. This method ensures a tender, flavorful meal with minimal fuss.
- Step 1: Place the 1.5 lb turkey tenderloins in the bottom of your crockpot. Season them generously with 2 teaspoons Italian seasoning, ¾ teaspoon salt, and ½ teaspoon black pepper. This initial seasoning layers in so much flavor right from the start.
- Step 2: Add the 8-12 oz sliced mushrooms, 1 medium onion, diced, and 3 garlic cloves, minced on top of the turkey. The aroma of the onions and garlic will start to build, promising a delicious outcome.
- Step 3: Pour in the 10.5 oz can cream of mushroom soup, ½ cup half and half, and ½ cup chicken broth. Stir gently to combine these liquids around the turkey and veggies. This forms the base of our incredibly creamy sauce.
- Step 4: Scatter the 8 oz block cream cheese, cut into cubes over the top. Don’t worry about spreading it evenly; it will melt into the sauce beautifully. This is what makes our creamy crockpot turkey tetrazzini so decadent.
- Step 5: Cover and cook on low for 5–7 hours, or on high for 3–4 hours, until the turkey is cooked through and fork-tender. You’ll know it’s ready when it shreds easily. The house will fill with a comforting, savory scent.

- Step 6: Carefully remove the tenderloins from the slow cooker and shred them into bite-sized chunks using two forks. This is a key step in achieving the perfect texture for this turkey tetrazzini slow cooker method.
- Step 7: Return the shredded turkey to the slow cooker. Stir in the 1 cup frozen peas, thawed and 1 cup shredded parmesan cheese or mozzarella.
- Step 8: Cover again and cook for another 10–15 minutes, just until the cheese is melted and everything is heated through. The sauce will thicken beautifully.
- Step 9: While the tetrazzini finishes, cook your 8 oz spaghetti noodles according to the package directions until al dente. Make sure not to overcook them!
- Step 10: Drain the spaghetti and gently stir it directly into the creamy sauce and turkey mixture in the crockpot. This step truly brings our turkey tetrazzini in a slow cooker all together.
- Step 11: Serve immediately, sprinkled with more parmesan cheese and fresh parsley if desired. Enjoy this delightful slow cooker tetrazzini turkey pasta!
Pro Tips for the Best Slow Cooker Turkey Tetrazzini
I’ve made this dish countless times, and these little tricks really elevate it from good to unforgettable. Follow these tips for the ultimate homemade crockpot turkey tetrazzini experience.
- For the creamiest sauce, ensure your cream cheese is at room temperature before adding it to the crockpot.
- Don’t overcook the pasta! It will continue to cook slightly in the hot sauce, so al dente is perfect.
- If using leftover cooked turkey, add it in the last hour of cooking just to heat through, rather than shredding raw tenderloins.
- Taste and adjust seasonings before serving. Sometimes a little extra salt or pepper is all it needs.

What’s the secret to perfect Crockpot Turkey Tetrazzini?
The secret lies in the combination of cream cheese and cream of mushroom soup creating an incredibly rich sauce. Using room temperature cream cheese ensures it melts smoothly for that signature velvety texture in your turkey tetrazzini crock pot recipe.
Can I make Crockpot Turkey Tetrazzini ahead of time?
Yes! You can assemble the ingredients (except the pasta and peas) in the slow cooker the night before. Refrigerate it, and then start it on low in the morning. Add the peas and pasta during the last 30 minutes of cooking.
How do I avoid common mistakes with Turkey Tetrazzini in a Slow Cooker?
A common pitfall is overcooking the pasta, making it mushy. Cook it al dente separately. Another mistake is not shredding the turkey enough, leading to large chunks. Ensure it’s well-shredded for even distribution in the sauce.
Best Ways to Serve Crockpot Turkey Tetrazzini
This hearty and comforting dish is fantastic on its own, but I love pairing it with a few simple sides to round out the meal. Serving this slow cooker tetrazzini turkey pasta feels so satisfying!
- Fresh Green Salad: A crisp, simple green salad with a light vinaigrette is the perfect contrast to the rich, creamy tetrazzini. It adds a refreshing element that cuts through the decadence beautifully.
- Steamed Broccoli or Asparagus: For a touch of green and some extra nutrients, a side of steamed vegetables like broccoli or asparagus works wonderfully. They are mild enough not to compete with the main dish.
- Crusty Bread: Don’t forget some crusty bread! It’s ideal for soaking up any of that delicious, cheesy sauce left on your plate. This is a must for enjoying every last bit of this turkey tetrazzini in a slow cooker.

Frequently Asked Questions About Crockpot Turkey Tetrazzini
Can I use leftover cooked turkey instead of tenderloins for this Crockpot Turkey Tetrazzini?
Absolutely! This is actually my favorite way to make it, especially after Thanksgiving. If you have about 3-4 cups of cooked, shredded turkey, just add it in during the last 30 minutes of cooking, along with the peas and cheese, to heat through. This makes for an even quicker turkey tetrazzini in a slow cooker.
What kind of pasta is best for this slow cooker turkey tetrazzini recipe?
While spaghetti is classic and works wonderfully for this turkey tetrazzini crock pot recipe, you can also use other shapes like fettuccine, penne, or rotini. Just make sure to cook your pasta separately until al dente, as it will continue to soften in the hot sauce. Adding it at the end prevents it from becoming mushy. For pasta cooking tips, see this guide on how to cook pasta.
How do I make Crockpot Turkey Tetrazzini creamier?
To achieve an extra creamy texture in your creamy crockpot turkey tetrazzini, you can add an extra ounce or two of cream cheese or a splash more half-and-half in the final stages of cooking. Stirring in a bit more shredded parmesan cheese right before serving also adds to the creamy, cheesy goodness. It’s all about that rich, comforting sauce!
Can I make this a healthier Crockpot Turkey Tetrazzini?
You can lighten this up a bit by using low-fat cream cheese and skim milk or a lighter half-and-half. Swapping out some of the pasta for extra vegetables like broccoli florets or spinach can also boost the nutritional value. This healthy crockpot turkey tetrazzini is still incredibly satisfying!
Variations of Crockpot Turkey Tetrazzini You Can Try
While this classic recipe is amazing, don’t be afraid to get creative! There are so many ways to adapt this dish to your tastes and needs. Trying these variations makes your turkey tetrazzini casserole crockpot experience even more exciting.
- Vegetarian Delight: Skip the turkey altogether and load up on extra mushrooms and veggies like bell peppers and zucchini. You can also use plant-based chicken or extra firm tofu for a hearty meatless option.
- Spicy Kick: Add a pinch of red pepper flakes or a dash of your favorite hot sauce to the slow cooker along with the other liquids. This transforms the dish into a zesty, flavorful meal.
- Cream of Chicken Swap: If you’re not a fan of mushroom soup, or just want a change, substitute the cream of mushroom soup with cream of chicken soup. It creates a slightly different, but equally delicious, flavor profile for your slow cooker tetrazzini turkey pasta.
- Gluten-Free Version: Use gluten-free pasta and ensure your cream of mushroom soup is also gluten-free. This adaptation makes the dish accessible for those with gluten sensitivities while keeping all the classic comfort.
