Tips on making hash brown casserole
  • You can purchase a 20 oz bag of ready to cook hash brown potatoes or you can make your own
  • Use whole milk or 2% milk
  • Use a blend of shredded cheese - cheddar and Monterey Jack, or your favorite cheese
  • Place casserole dish on a baking sheet when baking. This helps prevent any messy overflow. It also helps prevent the bottom of the casserole from becoming too dark. 
  • Check casserole after 45 minutes of baking. If becoming too dark on the top, cover with a piece of foil. Return to oven for an additional 15 minutes. 


To make ahead
  • Place all ingredients in the casserole dish and cover with foil. Refrigerate overnight. Remove from refrigerator at least 30 minutes before baking. Increase baking time by 15 minutes.
