My sister holly has made these yummy potatoes several times for us at family gatherings and shared the recipe.
2 packages frozen hash browns, thawed (microwave helps)
1/2 medium onion, chopped
2 cans cream of chicken soup
1 1/2 tubs sour cream (total 24 oz.)
2-3 cups shredded cheddar cheese
additional 1-2 cups shredded cheese for topping
Mix together hash browns and onion, set aside. In a saucepan combine cream of chicken soup and sour cream and stir until smooth. Add shredded cheese and stir until melted. Add the potato mixture with sauce and stir until combined.
Pour into a dutch oven and bake at 350 degrees until hot and bubbly, approx 45 min to 1 hr. Add 1-2 cups additional shredded cheese and cook for additonal 15-minutes.
