Follow these steps to create The Best Chicken Bacon Ranch Casserole with Potatoes:

1. Preheat the Oven: Start by preheating your oven to 375°F (190°C) to prepare for baking.
2. Prepare Potatoes: In a pot, boil the diced potatoes in salted water until they are fork-tender, usually about 10-12 minutes. Drain well.
3. Mix Ingredients: In a large bowl, combine the shredded chicken, crumbled bacon, boiled potatoes, ranch dressing, garlic powder, onion powder, salt, and black pepper. Mix until evenly coated.
4. Add Cheese: Fold in 1 ½ cups of shredded cheddar cheese, reserving the remaining ½ cup for the topping.
5. Prepare Baking Dish: Drizzle olive oil in a 9×13 inch baking dish and spread it around to prevent sticking.
6. Transfer Mixture: Pour the chicken and potato mixture into the prepared baking dish, spreading it out evenly.
7. Add Topping: Sprinkle the remaining cheddar cheese evenly over the top of the casserole.
8. Bake: Place the casserole in the preheated oven and bake for 40-45 minutes, or until the cheese is bubbly and golden brown.
9. Cool Down: Once baked, remove the casserole from the oven and let it cool for 10-15 minutes before serving.
