Scoop 1/4 cup of potato mixture into each muffin cup. Use a small glass to press the potato mixture firmly into the bottom and up the sides of each cup.
Alternately, drizzle each with melted butter.
Bake for 22-25 minutes or until cooked through and golden. Sprinkle with shredded cheese in the last few minutes of baking.
Remove from the oven and gently run a knife or an offset spatula around each nest to loosen the edges.
Allow to cool in the pan for around 2 minutes before attempting to remove.
