How Much Potato Salad for 50 People (Perfectly Scaled Recipe)
Ingredients
- 8 lbs Yukon Gold or red potatoes, cut into 1-inch chunks
- 2 tablespoons kosher salt (for boiling water)
- 1½ cups mayonnaise
- ½ cup sour cream or plain Greek yogurt
- 3 tablespoons yellow mustard
- 3 tablespoons apple cider vinegar
- 1½ teaspoons celery salt
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- 1 teaspoon black pepper
- 8 large hard-boiled eggs, roughly chopped
- 1½ cups celery, finely diced (6-7 stalks)
- ¾ cup red onion, finely diced
- ¾ cup dill pickles, finely chopped (or ⅓ cup sweet relish)
- 2 tablespoons fresh dill, chopped (or 2 teaspoons dried)
- Smoked paprika to garnish
Instructions
- 1Cut potatoes into 1-inch chunks — no need to peel Yukon Gold or red potatoes. Keep pieces uniform for even cooking.
- 2Place potatoes in a large pot and cover with cold water by 2 inches. Add 2 tablespoons kosher salt. Bring to a boil over high heat, then reduce to a steady simmer.
- 3Cook for 12-15 minutes until a fork slides in easily but the potatoes still hold their shape. Do not overcook — they will continue softening as they cool.
- 4Drain immediately and spread across two large sheet pans in a single layer to cool. Speed this up by placing the pans in the fridge for 20-30 minutes.
- 5While the potatoes cool, whisk together mayo, sour cream, mustard, apple cider vinegar, celery salt, garlic powder, onion powder, and black pepper in a large bowl.
- 6Once potatoes are completely cool (not warm — warm potatoes will make the dressing greasy), add them to the dressing along with the eggs, celery, red onion, and pickles.
- 7Fold everything together gently with a large rubber spatula. Taste and adjust — more vinegar for tang, more salt, more mustard if needed.
- 8Fold in fresh dill, cover tightly, and refrigerate for at least 2 hours. Overnight is better.
- 9Before serving, stir gently, taste again, and adjust seasoning if needed. Transfer to a serving container and dust with smoked paprika.
The question comes up every time someone is planning a cookout, a reunion, a graduation party, or any event where the guest list hits 50. How much potato salad do you actually need? Get it wrong and you either run out in the first 20 minutes or spend the rest of the week eating leftovers. After making this for more large gatherings than I can count, I have the math locked in.
The short answer: plan for half a cup of potato salad per person if it is one of several sides. That works out to about 25 cups of finished salad — made from roughly 8 lbs of potatoes. If potato salad is the main side dish at the event, bump it to three-quarters of a cup per person and use 10-12 lbs of potatoes.
The Quantity Breakdown
Half a cup sounds small but it is the standard catering portion for a side dish. People take what they see — at a full spread with multiple options, most guests serve themselves between a half cup and three-quarters of a cup. Where things go wrong is when hosts plan for a full cup per person, end up making twice as much as needed, and wonder why there are 20 lbs of potato salad left at the end of the night.
For 50 people: 8 lbs of potatoes, this recipe as written, feeds the crowd comfortably with a small amount to spare. For 25 people cut everything in half. For 100 people double it and use two large mixing bowls — trying to toss 16 lbs of potato salad in a single bowl is how dressing ends up on the floor.
Choosing the Right Potato
Waxy potatoes — Yukon Gold, red potatoes, or fingerlings — are the right call for potato salad. They have lower starch content than russets, which means the cells stay intact during boiling instead of breaking down into a paste. The result holds its shape in the bowl and on the plate rather than turning into a mashed texture once the dressing hits it.
Russets will work in a pinch but they absorb a lot of dressing, can turn mealy, and tend to fall apart when stirred. For a crowd of 50, Yukon Golds are the most forgiving — consistent texture, buttery flavour, and they look good on the plate without peeling.
Make It the Day Before
Potato salad for a crowd is a make-ahead dish. The flavour is noticeably better after a night in the fridge — the potatoes absorb the dressing, the vinegar mellows, and everything tastes like it was meant to be together. Make it up to 24 hours ahead, cover tightly, and refrigerate. Pull it out 20 minutes before serving so it is not ice cold.
The one thing to hold back until right before serving: the paprika garnish and any fresh herbs. Add those just before it goes on the table — they will look fresh and intentional rather than soggy and oxidized.
Transport and Food Safety
Keep potato salad in a cooler with ice until serving time. At room temperature, potato salad should not sit for more than 2 hours — less if it is a hot day. Use a large food-grade container with a tight lid rather than plastic wrap over a bowl. At an outdoor event in summer heat, keep it in the cooler and serve in smaller batches, refreshing from the cooler as needed.
Roasted Potato Variation
For something different, skip the boiling and roast the potatoes instead. Cut Yukon Golds into 1-inch cubes, toss with olive oil, salt, and smoked paprika, and roast at 425°F for 30-35 minutes until golden and crispy at the edges. Let them cool completely, then dress with a dijon vinaigrette instead of a mayo base. It is a warm-weather salad that holds up without refrigeration for longer than the mayo version — useful when you cannot guarantee a cooler will be available.
Serving
Serve in a wide, shallow container so guests can see the full salad and serve themselves easily. A deep bowl makes it harder to scoop and leads to uneven distribution of the toppings. Garnish with a dusting of smoked paprika and a few sprigs of fresh dill. Simple, recognizable, and it tells people exactly what they are about to eat. Save this recipe to Pinterest before your next big event — this is the one you will come back to every summer.
Why This Works
Waxy potatoes (Yukon Gold, red) have lower amylose starch content than russets. During boiling, their cell walls stay more intact, which is why they hold shape instead of crumbling. Starting potatoes in cold water and bringing everything to a boil together (rather than adding to boiling water) ensures the exterior and interior cook at similar rates, reducing the chance of mushy outsides and raw centres. Dressing the potatoes while they are slightly warm — not hot, not fully cold — allows the vinegar in the dressing to penetrate deeper into the flesh and season the interior of each piece, not just the surface. By the time the salad is fully chilled, the flavour is built into the potato rather than sitting on top of it.
Frequently Asked Questions
How much potato salad do I need per person?▾
Plan for ½ cup per person if potato salad is one of several sides. If it is the main side dish, go with ¾ cup per person. For 50 people at a full spread: 8 lbs of potatoes. For 50 people where potato salad is the star: 10-12 lbs.
Can I make potato salad for 50 people the day before?▾
Yes — and you should. The flavour is noticeably better after the potatoes have had time to absorb the dressing overnight. Make it up to 24 hours ahead, cover tightly, and refrigerate. Hold the paprika garnish and fresh herbs until just before serving.
What potatoes are best for potato salad?▾
Waxy potatoes — Yukon Gold, red potatoes, or fingerlings — hold their shape better than russets. Russets absorb more dressing and can turn mealy once stirred. For a large batch, Yukon Golds are the most consistent and forgiving.
How do I safely transport and serve potato salad at an outdoor event?▾
Keep it in a cooler with ice until serving. Potato salad should not sit at room temperature for more than 2 hours — less on a hot day. Serve in smaller portions from the cooler and replenish as needed rather than putting the whole batch out at once.
How do I scale this recipe up or down?▾
The base ratio is 1 lb of potatoes per 6 servings (½ cup each). For 25 people use 4 lbs of potatoes and halve all dressing quantities. For 100 people use 16 lbs and double everything — mix in two separate large bowls for easier handling.
