  • Green Onions Substitute fresh chives or leeks.

Premade mashed potatoes from the store are a perfect way to cut down on prep time! Although your house won’t smell like buttery mash, this recipe won’t hurt from not having homemade.

Best Casserole Tips

  • You can use creamy or chunky potatoes. For more color, try Yukon gold or mini red potatoes and leave the skins on.
  • Shred your own cheese. Store bought shredded cheese doesn’t melt as well.
  • A potato masher makes the perfect consistency in my opinion!
  • Avoid extra prep fuss and buy Pre-made mashed potato and precooked bacon or cooke the bacon and potatoes ahead of time.
  • Forget the mess of potato being glued onto the baking dish and spray a nice layer of cooking spray.
  • Make this in the slow cooker too!
  • Serve your potato casserole with filling entrees like chicken, or crispy salad.
  • Make and freeze in advance for up to two months to have an easy dinner ready ahead of time!
