1. Start by placing the eggs in a medium saucepan. Cover them with 1 inch of water, ensuring they are fully submerged. Turn the heat to high and bring the water to a rolling boil.
2. Once the water is boiling, remove the pan from heat, cover it with a lid, and let it sit for 10 minutes.
3. While the eggs are resting, prepare an ice water bath in a medium bowl by filling it with 1 quart of cold water and adding ice cubes.
4. After 10 minutes, carefully transfer the eggs to the ice water bath using a slotted spoon. Let them sit for about 5 minutes.
5. Once cooled, gently tap each egg on a hard surface and peel off the shell. Rinse them under cold water to remove any stubborn bits of shell.
6. In a medium mixing bowl, combine the diced eggs with the other ingredients: mayonnaise, minced red onion, parsley, chopped celery, Dijon mustard, lemon juice, salt, and black pepper.
7. Gently mix all the ingredients together, ensuring the eggs are well coated in the mayonnaise and the flavors are evenly distributed.
8. Once combined, taste the mixture and adjust seasoning as needed.
9. Finally, transfer the salad into an airtight container. If you're not serving it right away, cover and refrigerate it overnight.
10. When you're ready to serve, scoop the Classic Egg Salad onto your favorite bread, crackers, or a bed of fresh greens. Enjoy!
