Also known as Chicken Spaghetti, Chicken Tetrazzini is a perfect weeknight comfort meal. A creamy cheesy dish, everyone will love.
Preheat oven to 350 degrees F.
Grease a 9x13 baking dish with oil, set aside.
In a large bowl, whisk together both soups, sour cream, butter, chicken broth, salt, pepper and garlic powder until combined.
Stir in the cooked shredded chicken, frozen peas and cooked spaghetti; toss all together to fully coat in the sauce.
Pour mixture into the prepared baking dish and sprinkle with the cheeses.
Cover the pan with foil and bake for 30 minutes.
After 30 minutes remove the foil and bake for another 15 minutes until the cheese is melted and the casserole is hot throughout.
Let sit for 5-10 minutes before serving. Sprinkle with chopped fresh parsley, serve and enjoy!
