To hard-boil eggs: Place them in a saucepan and cover with water approximately ½ inch above the eggs. Bring the water to a vigorous boil over high heat. Once boiling, remove from heat, cover, and let the eggs sit for 15–17 minutes. Immediately transfer them to a bowl filled with ice water for 5 minutes to cool.
Refrigerate any leftovers in a sealed container for up to 4 days.
