Creating an incredible Chicken and Potato Casserole can be straightforward if you follow these simple steps:

1. Preheat the Oven: Preheat your oven to 350°F (175°C) to prepare for baking the casserole.
2. Prepare the Potatoes: Peel and dice the potatoes into even-sized pieces to ensure uniform cooking.
3. Cook the Potatoes: Boil the diced potatoes in a pot of salted water for about 10-15 minutes, or until fork-tender. Drain and set aside.
4. Sauté the Onions: In a skillet, heat olive oil over medium heat. Add the chopped onions and sauté until they become translucent, about 5 minutes.
5. Mix Ingredients: In a large bowl, combine the cooked potatoes, shredded chicken, sautéed onions, cheddar cheese, cream of chicken soup, sour cream, garlic powder, onion powder, paprika, salt, and pepper. Mix well until all ingredients are combined.
6. Transfer to Baking Dish: Pour the mixture into a greased 9×13 inch baking dish, spreading evenly.
7. Add Topping (If Using): If you’re using bread crumbs, sprinkle them over the top of the mixture for added crunch and texture.
8. Bake: Place the dish in the preheated oven and bake for 45 minutes to an hour, until the top is golden and bubbly.
9. Cool Slightly: Once removed from the oven, allow the casserole to cool for about 10 minutes before serving. This cooling time helps it set a bit.
10. Garnish and Serve: Garnish with freshly chopped parsley for a touch of color and enjoy!

By following these simple steps, you’ll have a delicious Chicken and Potato Casserole ready to impress your family and friends.
