Put the eggs into a stock pot and cover with 1-2 inches of cold filtered water. Add 2 tablespoons of distilled white vinegar and bring it to a rolling boil. Cover the pot then turn off the stove. Allow the hard boiled eggs to sit on the stove burner, covered with a lid for about 11-12 minutes.
Drain the water from the hard boiled eggs and immerse them in ice cold water to stop them from cooking further. When they're cool enough to touch, carefully peel and slice each of your eggs in half lengthwise.
Carefully separate the yolks from the whites with a spoon then transfer the egg yolk to a small mixing bowl. Put the egg whites aside.
Add the avocado, lemon juice, mayonnaise and all spices to the mixing bowl with the egg yolks. Mash everything together until everything is well combined.
Fill each egg white half with a tablespoon of the avocado deviled eggs mixture and top with fresh chopped parsley. Serve your keto deviled eggs immediately on a deviled egg tray or later and enjoy the burst of flavor!
