Step-by-Step Instructions

- Assemble the Casserole: Pour the entire hash brown mixture into the prepared baking dish, spreading it evenly.

- Bake to Golden Perfection: Cover the baking dish tightly with aluminum foil. Bake for 45 minutes.
- Uncover and Brown: Remove the aluminum foil and bake for an additional 15-20 minutes, or until the top is golden brown and bubbly. The aroma filling your kitchen will be heavenly!

Storing and Reheating Tips
- Refrigeration: Allow Grandma’s Hash Brown Casserole to cool completely to room temperature. Once cooled, cover the baking dish tightly with plastic wrap or transfer the leftovers to an airtight container. It will stay fresh in the refrigerator for 3-4 days.
- Freezing: For longer storage, let the casserole cool completely. You can freeze it either in the baking dish (ensure it’s freezer-safe) or portion it into individual freezer-safe containers or bags. Well-wrapped, it can be frozen for up to 2-3 months.
- Reheating from Refrigerator: To reheat, preheat your oven to 350°F (175°C). Cover the casserole with foil and bake for 20-25 minutes, or until heated through. If the top isn’t as crispy as you’d like, remove the foil for the last 5-10 minutes of baking. You can also reheat individual portions in the microwave, covering them loosely with a paper towel, for a quick option.
- ** Reheating from Frozen:** If reheating from frozen, it’s best to thaw it in the refrigerator overnight first. Then, follow the reheating instructions for refrigerated leftovers. Alternatively, you can bake it directly from frozen, but increase the cooking time significantly and be sure to keep it covered with foil until heated through.
