Ingredients

Pasta

• 16 oz linguini (or fettuccine, spaghetti, bucatini, etc.)

Casserole

• 1/4 cup butter, softened (for buttering the casserole dish)
• 1 rotisserie chicken, shredded
• 2 cups shredded mozzarella cheese
• 1 cup shredded cheddar cheese
• 1/4 cup grated parmesan cheese

Tetrazzini Sauce Base

• 2 cans (10.5 oz each) cream of chicken condensed soup
• 8 oz block cream cheese, softened
• 5 garlic cloves, minced
• 1 cup sour cream
• 1.5 cups chicken broth
• 1 tsp dried parsley (plus more for topping)
• 1/2 tsp black pepper
• 1 tsp Italian seasoning

Optional add-ins:

• Sautéed mushrooms or onions for extra flavor
• A pinch of crushed red pepper for mild heat

Preparation Method

Preheat your oven to 350°F (175°C). Lightly butter a 9×13-inch casserole dish with softened butter and set aside.

Cook the pasta in a large pot of salted boiling water until al dente, according to package instructions. Drain the pasta, reserving about 1/2 cup of the pasta water, and set aside. This ensures the sauce has a little moisture if needed later.

Prepare the sauce by combining the cream of chicken soup, softened cream cheese, sour cream, chicken broth, minced garlic, dried parsley, black pepper, and Italian seasoning in a medium saucepan. Cook over medium heat, whisking constantly until the cream cheese is fully incorporated and the sauce is smooth. If the sauce seems too thick, add a splash of reserved pasta water to loosen it.

In a large mixing bowl, combine the cooked pasta, shredded rotisserie chicken, and sauce. Stir until all ingredients are evenly coated. Taste and adjust seasoning if needed.

Pour the mixture into the prepared casserole dish. Sprinkle the shredded mozzarella, cheddar, and parmesan cheeses evenly over the top. For an extra touch of flavor and color, sprinkle a bit of additional parsley over the cheese layer.

Cover the casserole loosely with aluminum foil and bake for 25 minutes. Remove the foil and bake for another 10-15 minutes, or until the cheese is melted and slightly golden on top. Allow the casserole to rest for 5-10 minutes before serving to let the flavors meld and make it easier to serve.

Tips and Variations

• Cheese: Feel free to experiment with cheese combinations. Gruyère, Monterey Jack, or Fontina can add a gourmet twist.
• Vegetables: Adding sautéed mushrooms, peas, spinach, or bell peppers can increase both nutrition and flavor.
• Protein options: Use leftover rotisserie chicken, poached chicken breasts, or even turkey for a holiday twist.
• Make-ahead: Assemble the casserole ahead of time and refrigerate until ready to bake. Bake for a few extra minutes if it’s coming straight from the fridge.
• Crispy topping: For a crunchy topping, mix 1/2 cup breadcrumbs with 2 tbsp melted butter and sprinkle over the cheese layer before baking.
