Creating Chicken Noodle Casserole is straightforward when you follow these simple steps:

1. Preheat the Oven: Preheat your oven to 350°F (175°C) to prepare for baking.
2. Cook the Noodles: In a large pot, cook the egg noodles according to package instructions. Drain and set aside.
3. Prepare the Sauce: In a mixing bowl, combine the cream of chicken soup, sour cream, milk, garlic powder, onion powder, salt, and pepper. Mix well until you have a smooth sauce.
4. Combine Ingredients: In a large bowl, combine the cooked chicken, drained noodles, sauce mixture, and if desired, frozen peas and carrots. Stir until everything is well coated.
5. Assemble the Casserole: Transfer the mixture into a greased 9×13-inch casserole dish. Spread it evenly across the dish.
6. Add Cheese: Sprinkle the shredded cheddar cheese on top of the casserole evenly for a gooey texture.
7. Top with Breadcrumbs: If you are using breadcrumbs, sprinkle them over the cheese layer for added crunch.
8. Bake in the Oven: Place the casserole in the preheated oven and bake for 30-40 minutes, or until the top is golden and bubbly.
9. Let it Cool: Remove from the oven and let it cool for a few minutes before serving. This helps the casserole set and enhances the flavors.

Following these steps will lead you to create an incredible Chicken Noodle Casserole effortlessly.
