Can I prepare the filling ahead of time?
Yes. Mix the yolk filling (mayonnaise, mustard, pickle juice, hot sauce, Old Bay) up to 2 days ahead and refrigerate. Stuff the egg whites just before breading and frying.
How do I keep the filling from leaking during frying?
Make sure the egg white halves are dry before dipping in the egg wash. Fill them just before breading. Fry at 350°F to cook the outside quickly before the filling heats through.
Can I bake these instead of deep-frying?
Yes. Arrange on a greased baking sheet and spray lightly with cooking oil, then bake at 375°F for 12–15 minutes until golden. They won't be quite as crispy but will still have a satisfying crunch.
How long do fried deviled eggs keep?
Store in an airtight container in the refrigerator for up to 2 days. Reheat in a 350°F oven for 5–7 minutes to restore crispness, or eat cold.
