Peel eggs and slice the eggs in half. Cut the eggs in half down their length, from tip to bottom.
Remove the yolks. Gently squeeze the yellow yolk out of the egg. Place the yolks into a medium-sized bowl. Place the eggs on a plate, cut side up.
Make the filling. In the bowl with the egg yolks add 3/4 cup mayonnaise, 1 tablespoon minced red onion, 2 teaspoons mustard, 1 teaspoon truffle oil, 1/4 teaspoon salt, and the minced dill pickle. Stir to combine. Mash the egg yolks as you stir. Stir until the egg mixture is creamy.
Fill the egg whites. Fill the eggs by spooning the egg yolk mixture into the egg whites. You can fill a piping bag, and pipe the filling into the egg whites.
Garnish - if desired. You can garnish with fresh herbs or a sprinkling of paprika if desired.
Recipe Tips
Chef's Notes
For the ultimate presentation, use a piping bag with a star tip to fill your egg whites. This simple technique elevates the appearance from homemade to restaurant-quality with minimal effort. If you don't have truffle salt, finishing with a light sprinkle of flaky sea salt and a drop of truffle oil works beautifully.
