These spooky spider deviled eggs are a fun and festive Halloween appetizer that looks like you spent hours on them but are actually quick and easy to make. Classic deviled eggs get a creepy makeover with black olive spiders, perfect for parties and guaranteed to be a crowd-pleaser.
For perfectly hard-boiled eggs, use eggs that are at least a week old—they peel easier. Add a teaspoon of baking soda to the boiling water to help loosen shells. If filling is too dry, add a teaspoon of mayo at a time; if too runny, add another yolk or a pinch of breadcrumbs. Olive legs may fall off—press them deeper into the filling, which acts like glue once set. Make ahead: boil and peel eggs, make filling, and store separately in fridge. Assemble spiders just before serving to prevent soggy olives. Store leftovers in an airtight container in the fridge for up to 2 days; do not reheat.
