- 1/2 cup of milk
- 1/4 cup of chopped green onions
- 1 teaspoon of garlic powder

Ingredient Notes and Substitutions
- Potatoes: Diced potatoes provide a hearty base. You can use frozen diced potatoes for convenience.
- Cheddar cheese: Adds a rich flavor. Feel free to substitute with your favorite cheese like Monterey Jack.
- Sour cream: Contributes creaminess. Greek yogurt can be a lighter alternative.
- Cream of mushroom soup: Gives depth to the flavor. You can use a homemade version or cream of chicken soup.
- Cornflakes: Add crunch on top. Panko breadcrumbs or crushed Ritz crackers work well too.
How to Make Cheesy Potatoes Casserole
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). This ensures that the casserole cooks evenly and gets that perfect golden crust.
Step 2: Prepare the Potatoes
Peel and dice the potatoes into small cubes. Uniform pieces allow for even cooking and a consistent texture throughout the dish.
Step 3: Mix Ingredients
In a large mixing bowl, combine the diced potatoes, cheddar cheese, sour cream, cream of mushroom soup, milk, green onions, garlic powder, salt, and pepper. Stir until everything is evenly mixed, making sure the potatoes are well coated.
Step 4: Transfer to Baking Dish
Pour the potato mixture into a greased 9×13 inch baking dish. Spreading it evenly helps it cook uniformly and prevents any parts from burning.
Step 5: Add Topping
If desired, sprinkle the crushed cornflakes over the top of the casserole. This adds a delightful crunch that complements the creamy interior.
Step 6: Bake the Casserole
Place the baking dish in the preheated oven and bake for 45 minutes. This allows the flavors to meld beautifully while the top turns golden.
Step 7: Check for Doneness
After 45 minutes, check if the potatoes are tender by inserting a fork. If they are still firm, continue baking and check every 5 minutes.
Step 8: Serve and Enjoy
Once done, remove the casserole from the oven and let it sit for a few minutes before serving. This waiting time allows the dish to set, making it easier to serve.
Pro Tip: Let the casserole sit for a few minutes before digging in; it makes serving much easier and allows the flavors to settle.
Tips for the Best Cheesy Potatoes Casserole
- Use freshly grated cheese for better melting and flavor.
- For creamier potatoes, consider adding more sour cream or a splash of heavy cream.
- Experiment with different types of cheese to find your favorite flavor combination.

- For added flavor, mix in some cooked bacon or ham.
Common Mistakes to Avoid
