Defrost the potatoes overnight in the fridge.
Spray your non-stick muffin tins with non-stick spray.
Press potatoes dry (this helps them crisp) in a large mixing bowl with paper towels.
You can also use a salad spinner to help dry the potatoes.
Mix all ingredients in the bowl.
Scoop about 1/2 cup of potato mixture into each muffin cup.
Bake 25-30 minutes at 400 degrees until crispy.
Store leftovers in air tight container. Reheat in microwave.
