How to Make Easy Chicken Tetrazzini

Step 1: Preheat and Prep

Preheat your oven to 350 degrees Fahrenheit. Coat a 9×13 inch baking dish with nonstick cooking spray.

Step 2: Make the Sauce

In a large bowl, whisk together the cream of chicken soup, cream of mushroom soup, sour cream, melted butter, chicken broth, salt, pepper, and garlic powder until well combined.

Step 3: Combine the Ingredients

Stir in the frozen peas, chopped or shredded cooked chicken, and cooked spaghetti. Toss to combine until everything is fully coated in the sauce.

Step 4: Assemble and Bake

Pour the mixture into the prepared baking dish. Sprinkle the mozzarella cheese, cheddar cheese, and Parmesan cheese evenly over the top. Cover the dish with foil and bake for 30 minutes. Remove the foil and continue baking for another 15 minutes, or until the cheese is melted and bubbly and the casserole is heated through.
