Step 1

Place potatoes into a large pot and cover with salted water; bring to a boil. Reduce heat to medium-low and simmer until tender, about 20 minutes. Drain and let cool enough to handle, 10 to 15 minutes. Cut into cubes.

Step 2

Mix mayonnaise, celery, onion, vinegar, mustard, salt, and pepper together in a large bowl. Add potatoes and mix to combine. Stir in eggs and sprinkle with paprika.
