Ingredients
- 20 pounds russet or Yukon Gold potatoes
- 4 cups mayonnaise (preferably full-fat for best texture)
- 2 cups sour cream
- 1 cup yellow mustard
- 2 1/2 cups finely diced celery (about 6-7 large stalks)
- 2 cups finely diced red onion (about 2 large onions)
- 2 cups dill pickles, finely chopped
- 16 large eggs
- 1 cup chopped fresh parsley (optional)
- 1/2 cup chopped fresh dill (optional, but recommended)
- 2 tablespoons celery seed
- 1/2 cup apple cider vinegar
- 1/4 cup sugar
- 4 teaspoons kosher salt (plus more, to taste)
- 2 teaspoons black pepper (plus more, to taste)
- Paprika, for garnish
Instructions
- Prepare the potatoes: Peel the potatoes and cut them into 1-inch cubes. Place them in a large stockpot and cover with cold water by at least 2 inches. Add 2 teaspoons of salt to the water.
- Cook the potatoes: Bring the water to a boil over high heat. Reduce to a simmer and cook for 10-15 minutes, or until the potatoes are fork-tender but not falling apart. Drain well and spread on baking sheets to cool slightly. Drizzle with apple cider vinegar while still warm to absorb flavor.
- Boil the eggs: Place the eggs in a large saucepan, cover with cold water, and bring to a boil. Once boiling, remove from heat, cover, and let sit for 12 minutes. Drain and transfer eggs to an ice bath. Peel and chop 12 eggs; reserve 4 for garnish.
- Mix the dressing: In a very large mixing bowl (or two if needed), combine mayonnaise, sour cream, mustard, sugar, 2 teaspoons salt, pepper, celery seed, diced pickles, celery, onions, parsley, and dill. Stir until well blended.
- Combine salad: Gently fold the cooled potatoes and chopped eggs into the dressing. Stir carefully to avoid mashing the potatoes. Taste and adjust seasoning with more salt, pepper, or vinegar as needed.
- Chill: Cover and refrigerate the potato salad for at least 4 hours, preferably overnight, to allow flavors to meld.
- Garnish and serve: Before serving, slice the reserved eggs and arrange on top. Sprinkle with paprika and extra herbs if desired. Serve cold.
Tips
- Potato choice: Yukon Golds hold their shape well; russets are creamier but can break down if overcooked. Use a mix for texture.
- Mayonnaise substitutions: For a lighter salad, replace up to half the mayo with plain Greek yogurt or use light mayo.
- Make ahead: Potato salad tastes best when made the day before. This allows the flavors to develop and meld.
- Don’t overcook potatoes: Overcooked potatoes become mushy; check frequently and drain as soon as they’re just tender.
Serving Suggestions
Potato salad is a versatile side that pairs well with grilled meats such as burgers, hot dogs, barbecue chicken, or pulled pork. It’s also a great side for sandwiches, fried chicken, or as part of a buffet spread with coleslaw, baked beans, and corn on the cob. For a picnic, serve it in chilled bowls over ice packs to keep it food-safe.
Variations
- Classic Southern Style: Add 1/2 cup sweet pickle relish and 1-2 tablespoons yellow mustard for a tangier, sweeter flavor.
- Bacon & Chive: Stir in 2 pounds cooked, crumbled bacon and 1 cup finely sliced chives for a smoky, savory twist.
- German Potato Salad: Omit mayonnaise and sour cream. Dress warm potatoes with a mixture of 2 cups cooked diced bacon, 1 cup diced onion sautéed in bacon fat, 1 cup apple cider vinegar, 1/2 cup sugar, and fresh parsley.
- Egg-Free: Omit eggs for allergies or preference. Add extra celery and pickles for crunch.
- Veggie-Loaded: Add 2 cups finely diced bell peppers, carrots, or peas for color and nutrition.
Storage and Reheating
Store potato salad tightly covered in the refrigerator. For food safety, do not leave it at room temperature for more than 2 hours. Potato salad keeps well for up to 4 days. Stir before serving to redistribute the dressing. Potato salad should not be frozen as the texture becomes watery and mushy upon thawing. Serve straight from the fridge; reheating is not recommended, as this is a cold dish. If serving at an outdoor event, keep the salad chilled in a cooler or over ice.
Frequently Asked Questions
- How much potato salad should I make per person?
For a side dish, plan on about 1/2 cup to 3/4 cup per person. This recipe makes approximately 25-30 cups, ensuring generous servings for 40 people, with some extra for seconds or leftovers. - Can I make potato salad in advance?
Yes, potato salad is actually better when made a day ahead. The flavors meld and the texture improves. Mix everything together, cover tightly, and refrigerate until serving. - How do I prevent watery or mushy potato salad?
Drain potatoes very well and let them cool before mixing with the dressing. Use waxy potatoes like Yukon Gold to help prevent mushiness, and avoid overcooking. Adding the vinegar while potatoes are warm helps flavor them without excess moisture. - Can I use red potatoes or other varieties?
Absolutely! Red potatoes hold their shape well and have a pleasant texture. You can substitute them for all or part of the potatoes in this recipe. Just be sure to cook until just fork-tender. - Is it safe to leave potato salad out at a picnic?
Potato salad should not sit out for more than 2 hours (or 1 hour if above 90°F). Keep it chilled in a cooler or over ice to prevent spoilage. Discard any leftovers that have been at room temperature for longer periods. - What if I need to make this gluten-free?
Potato salad is naturally gluten-free, but always check your mayonnaise, mustard, and pickles for hidden gluten or cross-contamination, especially if serving to those with celiac disease or gluten sensitivity.
