Step 1

Set the potatoes in a large pot; add 1 tablespoon salt and cover with cold water by 1 inch. Set over high heat and cook just until fork-tender, about 15 to 20 minutes. (You still want the potatoes to still have some shape to avoid turning the dish into mashed potatoes.) Drain potatoes, and set them aside to cool.

Step 2

As potatoes cool, make the dressing: To a large bowl, add mayonnaise, relish, mustard and granulated onion; whisk to combine.

Step 3

Add the potatoes to the dressing, along with the diced hard-boiled eggs, and celery, if using; stir gently to combine. Taste and season with salt and black pepper as needed.

Step 4

Chill for at least 2 hours, and up to overnight. Serve cold. Finish with a sprinkle of paprika. Potato salad will keep for 4 days in an airtight container.
