Preheat oven to 350°F. Place one egg into each cavity of a 12-cup muffin tin.
Pour water into each cavity to fill about ⅓ of the way.
Place muffin tin in oven and bake eggs for 30 minutes.
Remove from the muffin cups (use a large spoon) and place eggs immediately into a large bowl filled with ice water for 2-3 minutes.
