Place eggs in a saucepan, cover with cold water, and bring to a boil. Remove from heat, cover, and let sit for 12 minutes. Transfer to an ice water bath for 5 minutes, then peel and pat dry.
In a large bowl, chop the eggs into small pieces, leaving a few chunky bits for texture.
Finely chop the celery, dill, onion, and pickles. Add them to the bowl with the eggs.
Stir in mayonnaise, yellow mustard, stone ground mustard, garlic salt, and black pepper until well combined.
Refrigerate for at least 30 minutes. Garnish with dried parsley if desired. Enjoy on sandwiches, lettuce wraps, or with crackers.
