Ingredient Notes + Variations

• Boneless, skinless chicken breasts – cook until tender, then shred right into the sauce for a hearty base.
• Cream of mushroom soup + cream of chicken soup – these create the creamy backbone and deep savory flavor.
• Sour cream – adds tang and keeps the sauce smooth and luscious.
• Chicken broth – loosens the mixture so the pasta cooks perfectly in the slow cooker.
• Garlic powder, onion powder, salt, black pepper, paprika – simple seasoning that brings balance and warmth.
• Spaghetti – breaks in half and cooks right in the sauce, soaking up all that flavor.
• Mozzarella + Parmesan cheese – melts into the pasta for that classic creamy finish.
• Parsley – fresh pop at the end for color and brightness, optional.

How to Make Chicken Tetrazzini

This chicken tetrazzini comes together in layers. Chicken and sauce cook first, then pasta joins the party, and finally the cheeses melt in for a creamy finish. For full recipe details, including ingredients and measurements needed, see the printable recipe card down below.

Step 1: Add Chicken + Sauce

Place chicken in the slow cooker. Stir together soups, sour cream, broth, and seasonings, then pour over the top.

Step 2: Cook Until Tender

Cover and cook on low until the chicken is cooked through and easy to shred. Remove, shred, and return it to the sauce.

Step 3: Add the Pasta

Break spaghetti in half and stir into the mixture. Cook on high until the pasta is tender, stirring halfway so everything cooks evenly.

Step 4: Finish with Cheese

Stir in mozzarella and Parmesan until melted and creamy. Garnish with parsley and serve warm.

Tips for Success

• Stir halfway through the pasta cooking time so nothing sticks together.
• Shred the chicken finely so it blends smoothly into the sauce.
• Add a splash more broth if the pasta needs extra moisture near the end.
• Let the dish sit for a few minutes before serving so the sauce thickens slightly.

What to Serve with Chicken Tetrazzini

• Garlic Bread– obviously.
• Roasted Green Beans– balances the richness with a little char.
• Caesar Salad– classic pairing with creamy pasta.
• Homemade Dinner Rolls– soft and fluffy on the side.
• English Pea Salad– peas and pasta just make sense.
