Ingredients in Cheesy Potato Casserole
Here’s the magic behind this cheesy masterpiece:
Potatoes
The heart of this casserole! Russet potatoes work best because they become fluffy and soft when baked, creating the perfect base.
Cheddar Cheese
A generous amount of shredded cheddar gives the casserole that creamy, melty goodness. If you’re feeling adventurous, try using a mix of cheddar and Monterey Jack for an extra layer of flavor.
Sour Cream
Sour cream brings a tangy creaminess to balance the richness of the cheese and potatoes, making the casserole irresistibly smooth.
Cream of Chicken Soup
This classic pantry staple provides extra creaminess and a savory flavor that makes the casserole even more delicious.
Butter
Butter adds richness and helps create that lovely golden-brown top as the casserole bakes. Plus, it enhances all those amazing flavors!
Garlic Powder
Just a little garlic powder goes a long way in adding depth of flavor to this dish.
Onion Powder
A pinch of onion powder gives the casserole that savory, aromatic edge that takes the flavor up a notch.
Salt & Pepper
Seasoning is everything! Salt and pepper bring out all the flavors in this dish, ensuring each bite is full of savory goodness.
Cornflakes (Optional)
For the topping, crushed cornflakes add a crunchy, golden layer that’s totally optional, but highly recommended for an extra bit of texture.

Instructions
Let’s get started on this cheesy goodness!
Preheat Your Oven
First, preheat your oven to 350°F (175°C). This step ensures that your casserole bakes evenly and turns out perfectly golden and bubbly.
Prepare the Potatoes
Peel and cube your potatoes into small bite-sized pieces. You can also choose to leave the skin on if you like a bit of texture. Place the cubed potatoes in a large pot and cover them with water. Bring to a boil and cook until the potatoes are fork-tender, about 10-12 minutes. Drain and set them aside.
Mix the Casserole Ingredients
In a large bowl, combine the cooked potatoes, sour cream, cream of chicken soup, melted butter, garlic powder, onion powder, salt, and pepper. Stir in the shredded cheddar cheese until everything is evenly mixed.
Transfer to a Baking Dish
Lightly grease a 9×13-inch baking dish, then transfer the potato mixture into the dish. Spread it out evenly to make sure it bakes uniformly.
Add the Topping
If you’re using cornflakes, sprinkle a generous layer of crushed cornflakes on top of the casserole. This will give it that irresistible crunchy topping. Drizzle a little melted butter over the cornflakes for an extra golden finish.
Bake to Perfection
Bake the casserole in the preheated oven for 30-35 minutes, or until it’s hot, bubbly, and golden on top. The cornflakes should be crisp and the cheese should be melted and bubbly.
Let It Cool (Slightly!)
Once baked, let the casserole sit for a few minutes before serving. This will allow it to firm up a little, making it easier to cut and serve.
