Despite its impressive flavor and appearance, this easy Chicken Tetrazzini recipe is straightforward, uses simple ingredients, and can be prepped ahead of time.

A Quick History of Chicken Tetrazzini

Chicken Tetrazzini is believed to have been named after Luisa Tetrazzini, a famous Italian opera singer in the early 1900s. Despite the Italian name, the dish itself is an American creation. Many culinary historians credit San Francisco as the birthplace of the recipe, though some claim New York.

What makes it distinctly American is the use of cream of mushroom soup or cream-based sauce combined with pasta and baked into a casserole—something you wouldn’t find in traditional Italian cuisine. Over time, Chicken Tetrazzini became a beloved comfort food, appearing in cookbooks, church potlucks, and holiday dinner tables across the U.S.

  • 3 cups cooked chicken (shredded or diced; rotisserie chicken works perfectly)

  • 1 medium onion, finely chopped

  • 2 cloves garlic, minced

  • 2 tablespoons butter

  • 1 can (10.5 oz) cream of mushroom soup

Optional Add-Ins:

  • 1 cup frozen peas or broccoli

  • ¼ cup breadcrumbs (for a crunchy topping)

Step-by-Step Instructions

Step 1: Cook the Pasta

  • Bring a large pot of salted water to a boil.

  • Cook spaghetti until just al dente (slightly firm to the bite, since it will bake further).

  • Drain and set aside.

Step 2: Prepare the Creamy Sauce

  • In a large skillet, melt butter over medium heat.

  • Add chopped onion and garlic; sauté until softened and fragrant.

  • Stir in both cans of cream soup, sour cream, and chicken broth.

  • Season with Italian seasoning, garlic powder, onion powder, salt, and pepper.

  • Mix until smooth and creamy.

Step 3: Combine Chicken and Pasta

  • Add shredded chicken into the sauce mixture.

  • Gently fold in the cooked pasta until everything is evenly coated.

Step 4: Assemble the Casserole

  • Preheat oven to 350°F (175°C).

  • Grease a 9×13-inch baking dish.

  • Pour the chicken and pasta mixture into the dish.

  • Sprinkle with mozzarella, cheddar, and parmesan cheese.

  • (Optional) Add breadcrumbs for a crunchy topping.

Step 5: Bake

  • Bake uncovered for 30–35 minutes, or until cheese is melted and bubbly.

  • If you like a golden top, broil for 2–3 minutes at the end.

Step 6: Serve

  • Let the tetrazzini cool for 5 minutes before serving.

  • Garnish with fresh parsley if desired.

What to Serve with Chicken Tetrazzini
