Step 1: Preheat Your Oven. Start by preheating your oven to 350°F (175°C). This ensures your cheesy potatoes will bake evenly and get that perfect golden color.
Step 2: Prepare the Potato Mixture. In a large mixing bowl, combine the thawed diced potatoes, softened butter, sour cream, and cream of chicken soup. Stir until well combined and creamy.
Step 3: Season It Up. Add kosher salt, pepper, and dried parsley to the potato mixture. Taste and adjust the seasoning as needed, ensuring the flavors are just right.
Step 4: Cheese It Up. Fold in the freshly grated sharp cheddar cheese into the potato mixture. This adds a wonderful cheesiness that will make your dish irresistible.
Step 5: Transfer to Baking Dish. Pour the potato mixture into a greased 9x13 inch baking dish, spreading it evenly.
Step 6: Add the Crunch. Sprinkle the crushed kettle-cooked potato chips generously over the top of the potato mixture. This will create a deliciously crispy topping.
Step 7: Bake. Place the baking dish in the preheated oven and bake for 45-50 minutes, or until the top is golden brown and the edges are bubbling.
Step 8: Serve and Enjoy. Once baked, allow the dish to cool for a few minutes before serving. Dig in and enjoy each cheesy, creamy bite of My Moms Cheesy Potatoes!
