Equipment

Instructions
- Preheat the oven to 350°F (175°C). Lightly grease a 9x13-inch baking dish with nonstick spray.
- In a large mixing bowl, whisk together cream of chicken soup, sour cream, salt, and black pepper until smoothish and combined.
- Add shredded cheddar cheese, green onions, and thawed hash brown potatoes to the bowl. Fold everything together with a spatula until evenly coated.
- Spread the mixture in the prepared baking dish, smoothing the top lightly but don’t pack it down too tightly.
- In a separate bowl, toss the crushed cornflakes with the melted butter until flakes are well coated and glossy.
- Sprinkle the buttery cornflake mixture evenly over the potato layer.
- Bake uncovered for 45–50 minutes, until bubbly at the edges and golden brown and crispy on top.
- Let the casserole rest at least 5 minutes before serving—this helps it settle and spares your tongue!
Notes
This casserole is excellent for prepping ahead—assemble up to 24 hours in advance and refrigerate until ready to bake (add 5–10 minutes extra cook time if cold). For a vegetarian version, use cream of mushroom soup instead of chicken. Easily add crumbled bacon, ham, or try panko or crushed potato chips for the topping if you’re out of cornflakes.
