This Million Dollar Ritz Chicken Casserole recipe is packed with flavor; rotisserie chicken in a savory creamy sauce with a buttery crushed Ritz cracker topping! You can serve it with a vegetable on the side, and I also give instructions on how to add veggies and/or rice to the casserole if you like. And I have a ton of helpful tips to make this meal budget-friendly!
Melt the butter in a medium saucepan over medium heat. Once melted, whisk in the flour and cook 1 minute, whisking constantly.
Whisk in the milk, chicken broth, dried minced onions, salt, garlic powder, and black pepper, and bring to a boil. Let it boil until thickened, about 1 to 2 minutes, stirring constantly.
Whisk in the cream cheese until fully incorporated. Remove from the heat.
To Assemble:
Preheat the oven to 375F. Spray the inside of a 9 by 9-inch baking dish (or another oven-safe dish with an equivalent capacity) with olive oil cooking spray.
Add the chicken, mozzarella, cottage cheese, sour cream, scallion, and sauce to a large bowl and mix to combine.
To Bake:
Pour the filling into the prepared baking dish and spread it out.
Sprinkle the Ritz mixture evenly on top of the filling.
Bake uncovered until the casserole is golden on top and bubbling, about 20 minutes.
Serve warm garnished with minced parsley.

Notes
Use Store-Bought Cream of Chicken Soup to Save Time: If you’re running short on time, you can use store-bought Cream of Chicken Soup instead of making your own! Use 1 (10.5 ounce) can of soup + 4 ounces cream cheese.
Rotisserie Chicken Alternatives: For a more economical option, you can roast chicken leg quarters at 400F for 35 to 40 minutes, let them cool until they’re not too hot to touch, and then chop up the meat. Alternatively, check out canned chicken! You can sometimes find them buy one get one free, which makes them a budget-friendly option. Or if you already have cooked chicken on hand, feel free to use that instead.
To Add a Vegetable to This Casserole: I like to serve this casserole with a vegetable on the side. However, if you want to make this a one-dish meal you can stir in 3 cups of steamed broccoli or 1 (12 ounce) package of frozen vegetables (thawed and drained) along with the other filling components. Use a 9 by 13-inch casserole dish instead of a 9 by 9-inch dish.
To Add Rice to This Casserole: Stir 2 cups of cooked rice in with the other filling components. Use a 9 by 13-inch casserole dish instead of a 9 by 9-inch dish.
