Defrost the potatoes overnight in the fridge. This is a key step! If you forget, simply place the frozen bag of shredded potatoes into a bowl of cold water.
Spray your non-stick muffin tins with coconut oil non-stick spray.
Press potatoes really dry, this helps them crisp and avoids soggy hash browns. You can use a salad spinner to dry them, clean kitchen dish towels, paper towels, or a piece of cheese cloth. Squeeze to remove all the excess liquid. Dry them really well so you don't see much moisture.
Once defrosted and dry, transfer the potatoes into a large bowl, and add green onions, parmesan cheese, sea salt, cracked pepper, and olive oil. Stir until well combined.
Scoop into well-sprayed muffin tin, and distribute the potato mixture in each in an even layer. Press down just a little bit, this helps them form their shape and bake.
Bake 45 minutes at 400 degrees until crispy.
Store leftovers (if any!) in the fridge and reheat in the microwave.
