Why You'll Love This Recipe
- It cuts down on prep time: The chicken, sauce, and veggies are added directly to the pot with minimal prepping, and then they are left to cook. The only other steps are shredding the chicken once it's ready and making the pasta.
- It's versatile: I love that you can serve this in many ways. Enjoy it over pasta, rice, or with more vegetables.
- It's budget-friendly: This is an inexpensive recipe, which makes it perfect for a family dinner. It's a great addition to your weekly rotation!
Ingredients
I use common ingredients for this chicken tetrazzini recipe, with cream of chicken soup being one of the most important.

- Chicken breast: You can use thighs in a pinch, but I find that they take longer to cook and aren't easy to shred. Ensure that your chicken breasts are boneless and thawed before they go in the slow cooker.
- Cream soup: Cream of chicken soup is one of my favorite crockpot ingredients because it's a great way to thicken and add flavor to a sauce or gravy with little effort. I use cream of mushroom soup as well to enhance the mushroom flavor.
- Cheese: I use shredded mozzarella and Parmesan cheese. I recommend shredding them yourself because they melt better without the anti-caking ingredients added to pre-shredded bags.
- Veggies: Fresh mushrooms and frozen peas are used to make this a classic tetrazzini recipe.
- Breadcrumbs: The breadcrumbs add a little texture to the dish. I toast the panko to get it perfectly crispy! You may use regular breadcrumbs if you prefer, but they won't have the same crunch.
- Spaghetti: This is traditional, but you can choose another shape like linguine, fettuccine, or even bowties for fun!

Variations
- Italian-style: Stir in freshly chopped basil and sundried tomatoes for a delicious Italian twist.
- Gluten-free: Use gluten-free soups and choose a gluten-free pasta, or use cooked cauliflower as the base.
- Try turkey: Turkey breast is a great alternative to this recipe, but ensure that it is fully cooked before shredding, especially if it is larger than average chicken breasts.
How to Make Crockpot Chicken Tetrazzini
These are instructions on how to make chicken tetrazzini in the crockpot. It doesn't take a lot of work before you get started. All you have to do is cook the pasta once the other components are ready.

Step 1: Add the chicken and mushrooms. Place the chicken breasts in the bottom of the pot and season them. Then, sprinkle in the mushrooms and cubes of cream cheese.

Step 2: Combine and add the soup mixture. Next, whisk the cream soups with chicken broth until smooth, and then pour over the top of the chicken.

Step 3: Cook and shred the chicken. Pop the lid on and cook on low for 4-5 hours or until the chicken is fully cooked and tender. Then, remove the chicken breasts and shred them with two forks.

Step 4: Stir cheese and chicken into the sauce. Next, mix the cheese into the sauce, and then put the shredded chicken back into the pot with the peas. Let it cook for about 15 minutes.

Step 5: Toast the panko. Now grab a skillet and toast the panko breadcrumbs over medium heat until golden brown.

Step 6: Serve. Spoon the chicken tereazzini over the cooked spaghetti and sprinkle the toasted panko on top!
Recipe Tips
- Use leftover chicken as a shortcut: Cook the veggies in the sauce on low for 2-3 hours and then add the cooked, shredded chicken for the last 30 minutes to warm it through. Try a rotisserie chicken or leftovers from another recipe.
- Don't overcook the pasta: Even though you are cooking it separately, I would still only cook it to al dente. Sometimes, I like to add it to the pot and mix it with the chicken and sauce, and this prevents the spaghetti from becoming mushy.
- Add broth or cream if it's thick: If the sauce is too thick for your liking, add a splash of chicken broth or heavy cream to thin it out slightly.
This crockpot chicken spaghetti is a perfect example of another slow-cooked creamy chicken meal.

Storage Directions
- Storing: Store leftover chicken tetrazzini in an airtight container for up to 3 days in the refrigerator. You may freeze the chicken and sauce for up to 2 months, and make the pasta fresh before serving.
- Reheating: You may reheat a portion in the microwave for 2-3 minutes or until warm (I recommend covering the plate with a paper towel). Use a saucepan over low heat as well. Add a splash of broth or water to loosen it up as needed.
Serving Suggestions
- Enjoy a tasty green veggie side dish with this crockpot chicken tetrazzini. I enjoy Parmesan zucchini bites and bacon-wrapped asparagus!
- Brighten up the meal with a side of cucumbers and onions in vinegar.
- You can't go wrong with some fluffy dinner rolls to soak up the extra creamy sauce.
- Prepare a refreshing drink like this white linen cocktail to make your dinner feel fancy.

Recipe FAQs
I don't recommend it because it won't cook properly or evenly. It's best to cook the components separately and then bring them together just before serving.
Sure! Cook the chicken breasts with the veggies and sauce mixture for about 20-25 minutes at high pressure, and make the spaghetti separately.
This can happen as it cools. Drizzle a little olive oil and toss the spaghetti to coat it, and that will keep it from clumping and sticking together.

I am making this tonight. I don't see in the recipe where you are supposed to add the onions. I guess they get sauteed with the mushrooms?
