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.
