Looking for an easy meal to make this week? Try this delicious Crock-Pot Chicken Tetrazzini and let your slow cooker do all the heavy lifting. 

Creamy mushroom chicken alfredo pasta served on a white speckled plate with fresh parsley garnish. A light, healthy, and delicious meal perfect for food lovers and fitness enthusiasts.

Oh, the Crock-Pot. Where do I start? It’s probably one of my favorite kitchen appliances, and boy, does it get used a lot during the week! It’s perfect for those busy weeknights when the last thing you want to think about is cooking dinner. Just set it and forget it—it’s that easy!  

Now that summer is transitioning into autumn, I’m bringing back all of my favorite Crock-Pot recipes—like this delicious chicken tetrazzini. Everything from the fork-tender chicken breast to the creamy, tangy mushroom-packed sauce reminds me why I love Italian-American recipes in the first place. The comforting and hearty elements of Italian-American dishes bring me so much joy, and this chicken tetrazzini recipe covers all the bases.

Last week, I whipped this up for dinner and served it to my nephews and partner. Let me tell you, this recipe is picky-eater-approved. Everyone around the table had their plates clean and cleared within minutes and were checking the Crock-Pot for seconds. Serve it with cooked spaghetti noodles like the recipe, or switch it up like I did and spoon it over some toasted sourdough bread. The crispy bread soaks up the creamy mushroom sauce perfectly, and will definitely make you want to add it to your weekly dinner rotation.

Can I use chicken thighs instead?

Yes! You can totally use chicken thighs instead of breast. I actually prefer chicken thighs in this recipe since the slow-cooking of the Crock-Pot perfectly tenderizes the meat, locking in the moisture and making it super juicy. The cooking method stays the same; just make sure to use boneless and skinless chicken thighs to avoid having to carve around the bone and remove the skin.

How do I store leftovers?

You can store any leftover chicken tetrazzini in an airtight container in the refrigerator for up to 3 days. You can also store it in the freezer for up to 2 months. To defrost, I recommend leaving it in the refrigerator to fully thaw. Once it’s thawed, reheat it in a lightly oiled pan over medium heat until it’s heated through. If it seems a bit dry or thick, add a bit of chicken broth or water to add back some moisture.

Serving suggestions

This chicken tetrazzini would be great served over cooked pasta, egg noodles, or even a thick slice of toasted sourdough bread. If you want to get some greens on the table, I recommend serving it with this lovely Spring Salad, some Roasted Zucchini, or this Sautéed Spinach. You can also serve it alongside this tasty Italian Salad and one of my favorite side dishes, Roasted Broccoli And Cauliflower.
