Step‑by‑Step Instructions for Million Dollar Potato Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C) while you prepare the other ingredients. Grease a 9×13-inch baking dish with a bit of butter or oil to ensure your Million Dollar Potato Casserole doesn’t stick, helping to achieve a perfectly golden crust on top.
Step 2: Boil the Potatoes
Next, peel and dice your Yukon Gold potatoes into uniform cubes. In a large pot, bring salted water to a boil and add the potatoes. Cook them for about 10-15 minutes, or until fork-tender—be careful not to overcook! Drain the potatoes thoroughly and set them aside to cool slightly.
Step 3: Mix the Casserole Filling
In a large mixing bowl, combine the sour cream, cream of chicken soup, shredded cheddar cheese, diced onions, melted butter, garlic powder, salt, and pepper. Stir the ingredients together until smooth and creamy, making sure everything is well-blended, which will be the delicious base for your Million Dollar Potato Casserole.
Step 4: Combine Potatoes and Mixture
Once your potatoes have cooled a bit, gently fold them into the creamy mixture in the bowl. Use a spatula to ensure each piece is evenly coated, creating a comforting and rich filling that will make your casserole delightful.
Step 5: Assemble the Casserole
Pour the potato mixture into the greased baking dish, spreading it out evenly. The creamy blend of potatoes and cheese should fill the dish nicely.
Step 6: Add the Topping
Now it’s time to add that irresistible crunch! Evenly sprinkle a generous layer of crushed cornflakes or potato chips over the top of the casserole. This will create a crispy texture that contrasts beautifully with the creamy filling.
Step 7: Bake to Perfection
Place the assembled Million Dollar Potato Casserole in the preheated oven and bake for 30-35 minutes. Keep an eye on it; once it’s bubbly and golden brown on top, you’ll know it’s ready to come out, filling your kitchen with an enticing aroma.
Step 8: Cool and Serve
After baking, allow the casserole to cool for about 5-10 minutes before serving; this will help it set up just a bit, making it easier to spoon out portions. Serve your delicious Million Dollar Potato Casserole warm as a satisfying side dish everyone will love.

Make Ahead Options
These Million Dollar Potato Casserole preparations are a dream for busy home cooks!
