  7. Bake until browned and set. Bake uncovered for 45 to 55 minutes, until the edges are lightly browned and the center is set and reaches 160°F. If the top browns too quickly, loosely cover it with foil during the final 10 minutes.

    Use oven mitts when removing the hot baking dish.

    Verify that the center reaches at least 160°F before serving.

  8. Rest, portion, and serve. Remove the casserole from the oven and rest for 10 minutes. Cut into 8 equal portions and serve warm.

    Use care when handling the hot casserole and baking dish.

Notes

For make-ahead preparation, assemble the casserole, cover tightly, and refrigerate for up to 24 hours. Let it stand at room temperature while the oven preheats, then bake as directed, adding 5-10 minutes if needed.

Thoroughly squeezing the thawed potatoes prevents a watery casserole and helps the edges brown.

Store cooled leftovers in an airtight container in the refrigerator for up to 4 days. Reheat individual portions in the microwave until they reach 165°F.

Cooking safety

Thaw the hash browns in the refrigerator rather than at room temperature.

Cook the egg mixture until the center reaches at least 160°F.

Keep eggs and milk refrigerated until needed, and do not leave the assembled casserole at room temperature for more than 2 hours.

Use oven mitts when handling the hot baking dish.

Refrigerate leftovers promptly and reheat them to 165°F.
