Ingredients You’ll Need
To make this easy cheesy potato casserole, gather the following:
2 pounds frozen shredded hash brown potatoes, thawed (about 32 ounces)
3 cups shredded cheddar cheese, divided
1 can (10.5 ounces) condensed cream of chicken soup
(Use cream of mushroom or cream of celery for a meatless option)
That’s all you need to create a rich, satisfying casserole.
Step-by-Step Instructions
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish with butter or cooking spray to prevent sticking.
Step 2: Mix the Ingredients
In a large mixing bowl, combine the thawed hash brown potatoes, 2½ cups of shredded cheddar cheese, and the condensed cream of chicken soup.
Stir until everything is evenly coated. The mixture will be thick and slightly sticky—this is exactly what you want for a creamy casserole.
Step 3: Adjust Seasoning (Optional)
Taste a small spoonful of the mixture if you like. Add a pinch of salt or black pepper if needed, keeping in mind that the cheese and soup already provide plenty of seasoning.
Step 4: Assemble the Casserole
Spoon the potato mixture into the prepared baking dish. Spread it into an even layer, gently pressing it into the corners so it bakes evenly.
Step 5: Add the Cheese Topping
Sprinkle the remaining ½ cup of shredded cheddar cheese evenly over the top of the casserole. This creates a melted, lightly golden finish.
Step 6: Bake Until Bubbly
Place the casserole in the preheated oven and bake uncovered for 40–50 minutes, or until:
The casserole is bubbling around the edges
The cheese on top is fully melted and lightly golden
If you prefer a deeper golden color, leave it in the oven for an additional 5–10 minutes.
Step 7: Rest and Serve
Remove the casserole from the oven and let it rest for about 10 minutes before serving. This helps the casserole set so it scoops neatly and allows the flavors to come together.
Serve warm and enjoy.
Variations & Helpful Tips
This casserole is a classic Midwestern favorite because it’s incredibly adaptable.
Make It Extra Creamy
Stir in ½ cup sour cream along with the soup for extra richness. This adds a fourth ingredient but is a very popular variation.
Meatless Option
Use cream of mushroom or cream of celery soup instead of cream of chicken for a vegetarian-friendly version.
Turn It Into a Main Dish
Add 1–2 cups diced ham or cooked crumbled bacon to make it hearty enough to serve as a main course.
Change the Potato Texture
Swap shredded hash browns for cubed frozen potatoes if you prefer a chunkier casserole.
Add Color and Flavor
Sprinkle a little paprika or black pepper over the cheese before baking for extra flavor and visual appeal.
Add Crunch
For a crispy topping, mix crushed cornflakes or buttered breadcrumbs with a small handful of cheese and sprinkle over the casserole during the last 15 minutes of baking.
This is a forgiving, farmhouse-style recipe—use what you have and make it your own.
