Recipe Notes

  1. Can I use fresh potatoes in this recipe?  If you don’t have frozen hash browns, you can use fresh potatoes in this cheesy hashbrown casserole. If you have fresh potatoes, you can go a couple of ways after peeling 2 pounds of either Russet or Yukon Gold potatoes. You can create your own hash browns using a grater or food processor. If you do this option, be sure to squeeze out any excess water after the potatoes are shredded. You could also dice the potatoes into very small ¼ inch by ¼ inch pieces. Follow the recipe the same way once you prep the potatoes
  2. Can I freeze this Hash Brown Potato Casserole?  This Cheesy Hash Brown Casserole is great to make ahead and freeze and save time for future meals! You can either prepare it entirely, then freeze or cook it and freeze it. To thaw, place in the refrigerator 24 hours in advance of cooking. Then place in a 350 degree oven for 30 minutes if already cooked or 45 minutes covered if not cooked then 10 minutes uncovered.
