Prepare the eggs: Slice the hard-boiled eggs in half and remove the yolks. Place the yolks in a bowl and set the whites aside on a platter.
Mash the yolks: Use a fork, potato masher, or hand mixer to mash the yolks until they’re smooth and crumbly.
Add flavor: Stir in the mayonnaise, spicy brown mustard, and pickle juice. Keep mixing until the filling is creamy and well combined.
Fill the eggs: Use a piping bag or a spoon to fill the egg whites with the creamy yolk mixture.
Garnish: Sprinkle with paprika for a pop of color and a hint of flavor.
