Tips for the Best Egg & Hash Brown Casserole

Thaw the Hash Browns

Removing excess moisture keeps the casserole from becoming watery.

Brown the Meat First

Cooking the sausage or bacon beforehand develops deeper flavor.

Don’t Overbake

Once the eggs are set, remove the casserole to keep it soft and fluffy.

Let It Rest

Waiting a few minutes before slicing helps everything hold together beautifully.
