Chicken Tetrazzini is a creamy baked pasta dish loaded with shredded rotisserie chicken, a rich and cheesy sauce, and plenty of tender fettuccine. This easy-to-make comfort food casserole is perfect for weeknight dinners, potlucks, or make-ahead meals.
Preheat the oven to 375°F (190°C). Grease a 9x13-inch baking dish with butter or non-stick cooking spray.
Cook the fettuccine in a large pot of salted boiling water according to package directions until al dente. Drain well.
In a large mixing bowl, whisk together the cream of chicken soup, softened cream cheese, minced garlic, sour cream, chicken broth, Italian seasoning, and black pepper until smooth.
Add the shredded rotisserie chicken, cooked fettuccine, and half of the mozzarella and cheddar cheeses to the sauce. Stir until well combined.
Transfer the mixture to the prepared baking dish. Top with the remaining mozzarella and cheddar cheeses.
Bake uncovered at 375°F for 35 minutes, or until the cheese is melted and bubbly.
Let cool for 5 minutes before serving.
Notes
Chef Jenn’s Tips
Use freshly shredded cheese for the best melt and texture. Pre-shredded cheese often has anti-caking agents that can make the sauce grainy.
A rotisserie chicken is a huge time-saver here, but you can also use any leftover cooked chicken or turkey.
Make this casserole up to one day in advance and refrigerate it, covered. Bake as directed when ready to serve; just add an extra 5 to 10 minutes of bake time if baking straight from the fridge.
