Easy Cheesy Potato Casserole with Diced Potatoes


Easy cheesy potato casserole with diced potatoes is the BEST side dish, and a staple at holiday tables! I amped up the flavor, too!



  • 40 oz. refrigerated diced potatoes
  • 4 green onions
  • 1 cup cream of chicken soup (condensed)
  • 1/4 cup melted butter
  • 1/2 cup sour cream
  • 1 tsp. garlic powder
  • 1/2 tsp. sea salt
  • 1/4 tsp. black pepper
  • 2 cups sharp cheddar cheese, divided
  • 1 1/2 cups fried onions


  1. Prep ingredients:
    Thaw potatoes if frozen.
    Thinly slice green onions.
  2. Preheat oven to 375 degrees F.
  3. In a large bowl, whisk together the soup, melted butter, sour cream, garlic powder, sea salt, and black pepper.
  4. Fold in potatoes, green onions, and sharp cheddar cheese. Place mixture into a 9×13 inch pan.
  5. Top with fried onions and bake covered with foil for 40 minutes. Remove foil and bake another 10-15 minutes, or until potatoes are tender. 


  • I used Simply Potatoes Diced Potatoes, but you could also use the version with onions.
