This 4-ingredient potato Sullivan salad is the kind of old-school side dish that shows up once and immediately becomes part of the family routine. It has that simple, creamy, comforting flavor people expect at late-summer cookouts, and it comes together without a long shopping list or any fussy prep. Recipes like this stuck around for decades for a reason: they’re affordable, dependable, and somehow always one of the first bowls to be emptied on the table.
Serve this chilled alongside ribs, burgers, grilled chicken, or pulled pork for an easy backyard meal. It also fits right in with baked beans, sliced tomatoes, corn on the cob, watermelon, and soft dinner rolls. Because it’s creamy and mild, it balances smoky or spicy main dishes especially well, and it’s a great make-ahead side for potlucks and picnic tables.
4-Ingredient Potato Sullivan Salad
Servings: 8
Ingredients
3 pounds potatoes, peeled and cut into bite-size chunks
6 large hard-boiled eggs, chopped
1 medium sweet onion, finely chopped
1 1/2 cups mayonnaise
Directions
1. Place the potato chunks in a large pot, cover with cold salted water, and bring to a boil. Cook until the potatoes are fork-tender but not falling apart, about 10 to 12 minutes. Drain well and let them cool until no longer steaming.
2. In a large mixing bowl, gently combine the cooled potatoes, chopped hard-boiled eggs, and finely chopped sweet onion.
3. Add the mayonnaise and fold everything together gently until the potatoes are evenly coated and the eggs start to blend into the dressing for a creamy texture.
4. Cover and chill for at least 2 hours before serving so the flavors can come together. Transfer to a serving bowl and, if you like, finish with a little cracked black pepper right before bringing it to the table.
Variations & Tips
Make-ahead tip: This salad is even better after a few hours in the fridge, so it’s ideal for busy workweeks or party prep. If it thickens up too much after chilling, stir in a small spoonful of mayonnaise before serving to loosen it back up.
Potato choice: Yukon Gold potatoes give this salad a buttery texture and pale yellow color, while russets create a softer, fluffier finish. Just be careful not to overcook them, since potatoes that are too soft can turn the salad mushy.
Add a little seasoning: Even simple recipes benefit from a final taste before serving. A pinch of salt, a few grinds of black pepper, or a tiny splash of pickle juice can brighten the flavor without changing the classic feel of the dish.
Texture variation: If your family likes a little crunch, stir in a spoonful of finely diced celery right before serving. It goes beyond the original four ingredients, but it adds a fresh bite that works really well for picnics and potlucks.
