Preheat oven to 350º F. Spray a 2 or 2.5 quart casserole dish with cooking spray.
In a large bowl, combine Ore-Ida Shredded Hash Brown Potatoes, cream of chicken soup and sour cream. Stir to combine.
Spray a small saucepan with cooking spray and heat onions until softened. Add to bowl (can add them without cooking, if desired).
Add in coconut oil, salt, pepper and cheese to hash brown mixture. Stir well.
Pour into prepared dish and sprinkle with a little cheese. Cover pan with tin foil. Bake in preheated oven for approximately 45 minutes and then take foil off for five minutes to melt cheese on top.
