Ingredients
- 60 pounds russet or Yukon Gold potatoes
- 5 dozen large eggs (60 eggs)
- 2.5 gallons mayonnaise (about 10 quarts)
- 1.5 gallons yellow mustard
- 4 quarts celery (about 32 cups), finely diced
- 3 quarts red onions (about 12 cups), finely diced
- 2 quarts dill pickles (about 8 cups), finely diced
- 2 cups white vinegar
- 2 cups granulated sugar
- 1.5 cups kosher salt (plus more to taste)
- 1 cup ground black pepper
- 1 cup fresh parsley, chopped (optional, for garnish)
- Paprika for garnish (optional)
Instructions
- Prepare the potatoes: Scrub and peel the potatoes. Cut them into 1- to 1.5-inch cubes for even cooking. Place in large stock pots (you may need to work in batches), cover with cold water, and add a pinch of salt per pot.
- Cook the potatoes: Bring the pots to a boil over high heat, then reduce to a simmer. Cook until potatoes are just tender when pierced with a fork, about 15-20 minutes. Avoid overcooking to prevent mushiness.
- Drain and cool: Drain the potatoes thoroughly and spread them in shallow hotel pans or on large baking sheets to cool quickly. Allow to cool to room temperature before mixing with other ingredients. (You can refrigerate to speed this up.)
- Boil the eggs: Place the eggs in another large pot, cover with cold water, and bring to a gentle boil. Once boiling, cover, turn off heat, and let sit for 12 minutes. Drain and transfer to an ice bath. Peel when cool, then chop into small pieces.
- Prepare vegetables: While potatoes and eggs are cooling, finely dice celery, red onion, and dill pickles. For best texture, keep pieces small and uniform.
- Mix the dressing: In a very large mixing bowl (or food-grade bucket), combine the mayonnaise, mustard, white vinegar, sugar, salt, and black pepper. Whisk until smooth and well-blended.
- Combine salad: In a series of large mixing bowls or clean tubs, gently combine cooled potatoes, chopped eggs, celery, onion, and pickles. Pour dressing over in batches, folding gently with a large spatula or gloved hands to avoid breaking up potatoes too much. Mix until everything is evenly coated.
- Taste and adjust: Taste for seasoning—add more salt, pepper, or vinegar as needed. If the salad is too thick, add a little milk or pickle juice to loosen.
- Chill: Cover tightly and refrigerate for at least 4 hours, preferably overnight. This allows flavors to meld and the salad to fully chill for safe serving.
- Serve: Transfer to serving trays or chafing dishes. Garnish with chopped parsley and a light dusting of paprika if desired. Keep chilled until serving time.
Tips
- Substitutions: For a lighter salad, substitute up to half the mayonnaise with plain Greek yogurt or sour cream. For added crunch, include diced bell peppers or radishes.
- Scaling down: To halve or quarter the recipe, simply divide all ingredients accordingly. This recipe is easily scaled for smaller crowds.
- Common mistakes: Overcooking potatoes leads to mushy salad, while undercooking leaves them hard. Always cool potatoes before mixing to prevent watery salad.
- Storage safety: Use hotel pans or shallow containers for even cooling and safe storage. Never leave potato salad at room temperature for more than 2 hours.
Serving Suggestions
- Serve as a classic side at barbecues, picnics, or graduation parties.
- Pair with grilled meats like chicken, burgers, sausages, or ribs.
- For a buffet, offer alongside coleslaw, baked beans, and fresh rolls.
- Garnish with extra chopped herbs or sliced hard-boiled eggs for an attractive presentation.
- Keep the salad chilled in insulated coolers or on ice trays to maintain food safety during outdoor events.
Variations
- Sour Cream & Chive: Replace half the mayonnaise with sour cream and add 2 cups chopped fresh chives for a tangier flavor.
- Southern-Style: Add 4 cups sweet pickle relish and 4 tablespoons celery seed for a sweeter, more traditional Southern taste.
- Bacon Ranch: Mix in 5 pounds cooked, crumbled bacon and substitute 2 quarts of the mayonnaise with ranch dressing. Add 2 cups chopped green onions.
- German Potato Salad: For a warm, vinegar-based version, omit mayonnaise, increase vinegar to 1.5 gallons, add 3 pounds cooked, crumbled bacon, and toss with 2 gallons sautéed onions while potatoes are still warm.
- Vegan/Dairy-Free: Use vegan mayonnaise and leave out eggs. Add extra pickles and fresh herbs for more flavor.
Storage and Reheating
Store potato salad in tightly covered, food-safe containers in the refrigerator. For a batch this size, divide into multiple shallow hotel pans or plastic tubs to ensure rapid, even cooling. Potato salad should be kept below 40°F (4°C) at all times. It can be made up to 24 hours in advance for best flavor, and will keep safely for up to 3-4 days refrigerated. Do not freeze, as the texture will deteriorate upon thawing.
Potato salad is best served cold, not reheated. If you do need to bring it to room temperature, set it out no more than 1 hour before serving, and return leftovers to the fridge promptly. Discard any salad left out for more than 2 hours (or 1 hour if the temperature is above 90°F/32°C).
Frequently Asked Questions
- How much potato salad should I plan per person?
- For a side dish at a large event, plan on 1/2 to 2/3 cup of potato salad per person. This recipe yields about 10 gallons, or roughly 150 generous 2/3-cup servings, which is ideal for a crowd where other sides are also offered.
- Can I make potato salad ahead of time?
- Yes, potato salad improves in flavor when made a day ahead. Prepare it up to 24 hours before your event and store covered in the refrigerator. Stir gently before serving to redistribute dressing and check for seasoning.
- How can I transport potato salad safely?
- Use sealed, food-grade containers and pack them in coolers with plenty of ice or ice packs. For very large events, consider renting refrigerated transport or using large insulated food carriers. Always keep potato salad below 40°F (4°C).
- What’s the best way to peel and chop so many potatoes?
- Enlist helpers if possible! Use a sturdy vegetable peeler and a large chef’s knife. Work in batches, and keep peeled potatoes in cold water to prevent browning before cooking. For large quantities, a food processor with a dicing attachment can speed up chopping.
- How do I keep my potato salad from turning watery?
- Always cool cooked potatoes completely before mixing with dressing. Excess moisture can be drained off by spreading potatoes on baking sheets after cooking. Use full-fat mayonnaise, which is less prone to separating than low-fat varieties.
- What if I don’t have enough refrigerator space?
- If refrigerator space is tight, use multiple coolers packed with ice or gel packs to chill and store the salad. Place containers in a single layer for best cooling, and monitor temperatures with a food-safe thermometer to ensure safety.
