Place eggs in a saucepan and cover with cold water. Bring to a boil, then reduce heat and simmer for 10 minutes. Drain and rinse with cold water. Peel the eggs.
Chop the peeled eggs and place them in a medium bowl.
Add mayonnaise, Dijon mustard, celery, red onion, and dill to the bowl. Mix well.
Season with salt and pepper to taste.
In a small skillet, melt the butter over medium heat. Add the panko breadcrumbs and toast until golden brown and crispy, stirring frequently.
Stir the toasted breadcrumbs into the egg salad mixture.
Serve immediately.
Notes
For extra crispiness, you can toast the breadcrumbs in the oven at 350ยฐF (175ยฐC) for 5-7 minutes.
You can add a pinch of paprika for color and a hint of spice.
This egg salad is great on toast, crackers, or in a sandwich.
