The first thing you’ll need to do is preheat your oven to 350 and grease a 13×9 inch pan.

Now in a skillet melt 1 tablespoon of butter and add in your diced onion. Sauté your onions for about 10 minutes or until translucent and soft.

In a large bowl combine the hash browns, sour cream, cream of chicken soup, and shredded cheddar cheese stir well.

Now spread the potato mixture in the bottom of your prepared pan.

Now in the skillet you sautéed your onions in melt the other 2 tablespoons of butter. Pour the cornflakes in the pan and stir to coat them with the melted butter. You can leave the cornflakes relatively in tact or crunch them up into crumbs.

Spread the cornflakes evenly across the potato mixture

Place the pan in the oven and bake for 40-45 minutes or until warm and bubbly and golden brown on top. Serve to your friends and family who are sure to love them!
