Place eggs in a saucepan and cover with cold water by about an inch. Bring to a boil over high heat, then immediately remove from heat, cover, and let stand for 10-12 minutes.
Drain the hot water and immediately fill the pan with ice water to stop the cooking. Let the eggs cool for at least 10 minutes.
Peel the cooled eggs, slice them in half lengthwise, and carefully scoop out the yolks into a medium bowl.
Add mayonnaise, Dijon mustard, white vinegar, salt, and pepper to the bowl with the egg yolks. Mash with a fork or a potato masher until smooth and well combined.
Spoon or pipe the yolk mixture back into the egg white halves. Top each deviled egg with crumbled bacon and chopped chives.
Cover and refrigerate until ready to serve. Enjoy!
Notes
For a smoother filling, you can use an electric mixer to blend the egg yolks and other ingredients. Adjust seasonings to your preference.
