This speedy chicken tetrazzini is the kind of no-fuss comfort food that feels like a warm hug after a long day. It’s creamy, cheesy, and packed with hearty ingredients like rotisserie chicken, Alfredo sauce, and tender spaghetti. A little bacon, some peas, and mushrooms round it out, while the crunchy almond topping gives it just the right contrast in texture.

With a short prep time and the help of pantry-friendly staples, this casserole is perfect for busy weeknights or when you need to feed a hungry crowd fast. It bakes up golden and bubbly and works well as a full meal on its own — or pair it with a crisp salad or green veggie for something extra.

Where the Name Comes From

It might sound Italian, but it is entirely American in origin. The dish is named after Luisa Tetrazzini, a famous Italian opera singer from the early 20th century. According to most accounts, it was created in her honor by a chef in the United States — likely at the Palace Hotel in San Francisco or possibly at the Knickerbocker Hotel in New York, depending on the source.

What to Serve with Chicken Tetrazzini
