Chicken spaghetti is a uniquely American dish in the lineup of classic comforting casseroles. With tender noodles and shredded chicken baked in a creamy, cheesy sauce, it’s historically made with canned cream soups and some kind of vegetable like tomatoes or bell peppers. My version delivers the same comforting flavors but with no canned cream soups, though it still has the defining hallmark of breaking up the spaghetti into small pieces before it’s cooked. Chicken spaghetti is a great way to use up leftover rotisserie chicken or even cooked roasted turkey should you find yourself looking for a new way to eat poultry.
