Ingredients Method Notes

Ingredients
  

  • 1/2 teaspoon onion powder – optional but adds savory depth
  • 32 ounce bag of frozen cubed hash brown potatoes – approx. 7 1/3 cups
  • 1/2 cup unsalted butter, melted and slightly cooled 113 g
  • 1 cup full-fat sour cream or Greek yogurt substitute 227 ml
  • 2 1/2 cups crushed cornflake cereal topping 70 g
  • 21.5 ounces canned condensed cream of chicken soup – reduced-fat variety
  • 12 ounces extra-sharp cheddar cheese, freshly shredded – around 3 cups approx. 3 cups

Method
 

Step 1: Preheat the Oven
  1. Start by preheating your oven to 350°F (175°C). This will ensure a warm environment for baking the casserole, promoting even cooking.
Step 2: Prepare Your Baking Dish
  1. Grab a large 9x13-inch baking dish. Lightly grease it with cooking spray or a little melted butter. This keeps the casserole from sticking to the pan, making cleanup a breeze.
Step 3: Mix Ingredients
  1. In a large bowl, combine the frozen hash browns, melted butter, sour cream, cream of chicken soup, onion powder, and half of your cheese. Mix everything well until it's evenly distributed. This is the core of your casserole — creamy and loaded with flavor!
Step 4: Pour Into Baking Dish
  1. Spoon the mixture into the prepared baking dish. Spread it out evenly using the back of a spoon or a spatula. Ensuring even layers helps with consistent cooking.
Step 5: Add Toppings
  1. Sprinkle the remaining cheese across the top of your casserole. Then, cover with a generous layer of crushed cornflakes. This is where the magic happens! The cornflakes will crisp up beautifully in the oven.
Step 6: Bake It Up!
  1. Place the casserole in your preheated oven. Bake for about 45-55 minutes, or until bubbly and golden brown on top. Around the 30-minute mark, check on it and cover with foil if it’s browning too quickly.
Step 7: Cool and Serve
  1. After baking, let the casserole cool for about 10-15 minutes before serving. This resting period helps it set up a bit, making it easier to scoop out those perfect portions.

Notes

  • Experiment with Cheeses: If cheddar isn't your favorite, try Monterey Jack or pepper jack for a twist in flavor.
  • Add Vegetables: Consider throwing in chopped spinach or broccoli for added nutrition. It also brings a nice color contrast.
  • Use Fresh Herbs: Sprinkle a little fresh parsley or chives on top before serving for a pop of freshness in flavor and presentation.
  • Make It Ahead: You can prepare the casserole a day in advance. Just cover it tightly and store it in the fridge. Bake it when you’re ready to serve.
  • Adjust Seasonings: Feel free to tweak amounts of onion powder, salt, or pepper based on your taste preferences.
