Baked Potato Salad Recipe With Mayonnaise: Creamy Celery Crowns Over Warm Spuds

This baked potato salad recipe with mayonnaise transforms humble spuds into a creamy, velvety masterpiece that tastes like summer in a bowl. 🌟 I developed it after years of testing—balancing warm potatoes with cool, tangy dressing for that perfect contrast.

The secret lies in baking the potatoes just until tender, then mixing them with a rich mayo-based dressing while still warm so every bite gets coated in that luscious, herby goodness.

What makes this recipe special is the celery crown technique—finely chopped celery and onions that soften just enough to create a subtle crunch without overpowering the potatoes. My grandmother used to say "the best potato salad starts with the right mayo," and she wasn't wrong.

We use a high-quality mayo here, but don't worry—this recipe delivers that signature creamy texture without being too heavy. The dressing gets tossed in while the potatoes are still warm, ensuring each bite is perfectly coated.

By the time you're done, you'll have a salad that's creamy yet light, with tender potatoes, crisp vegetables, and just the right amount of tangy dressing. The flavors meld beautifully as it chills, becoming even more delicious after sitting for a few hours.

This is the kind of dish that disappears quickly at picnics, potlucks, or family gatherings—everyone will be asking for the recipe.

For extra flair, I like to top it with crispy bacon bits or fresh chives, but the base recipe is foolproof as-is. The best part? You can make it ahead and let the flavors develop even more. Let's get cooking—this salad is about to become your new favorite side dish.

Ingredients for baked potato salad recipe with mayonnaise

Creamy, velvety, and packed with that signature celery crown crunch—this salad delivers summer in every bite.

The potatoes are the star, so Russet potatoes are a must—they're waxy enough to hold shape but fluffy when baked. Costco or Walmart usually have them pre-washed, but scrubbing them yourself ensures no dirt hides in the crevices. For the mayo, Hellmann's or Duke's are my go-tos—they're rich but not too heavy. Fresh dill and chives are worth the splurge at the grocery store; the produce section usually has the best selection. If you're short on time, frozen chopped onions work in a pinch for the celery crowns, but fresh is always better.

No fresh dill? Dried dill at one-third the amount gets you close, but it lacks that bright freshness. Short on mayo? Greek yogurt mixed with a bit of lemon juice lightens things up nicely. The celery crowns are key—finely chop the celery and onions so they soften just enough to add texture without overpowering. Trader Joe's has pre-chopped celery if you're in a hurry, but chopping your own gives you control. For extra tang, swap apple cider vinegar for lemon juice—just add a pinch more sugar to balance it.

Baked potatoes keep best in the fridge for 3-4 days if you make them ahead, but tossing in the dressing while still warm is key. The salad itself stays fresh for 4-5 days in an airtight container, and honestly, it tastes even better the next day as the flavors meld. For picnics, I like to portion it into mason jars—layer the potatoes at the bottom, then the dressing on top so it stays creamy when you pour it out. The bacon bits can be added fresh before serving, or stored separately if you're prepping ahead.

Step-by-step instructions for creamy baked potato salad with celery crowns

Here's how to make the most luscious baked potato salad—warm, creamy, and packed with fresh celery crowns.

Preheat your oven to 400°F and line a baking sheet with parchment paper. Pierce each of the 3 lb Russet Potatoes with a fork in several places—this prevents them from bursting. Place them directly on the baking sheet and bake for 45-50 minutes until completely tender.

You'll know they're done when a knife slides in easily with no resistance. Let them cool slightly for 10 minutes before handling—they'll be piping hot! While they bake, prepare your toppings so everything comes together efficiently.

Trim the bottoms off the 3 whole Celery Stalks and use a sharp knife to slice off the leafy tops. Make a horizontal cut about 1 inch from the bottom, then slice vertically into ¼-inch thick pieces. This creates beautiful celery crowns that stay crisp even when mixed with warm potatoes.

Finely chop the 1.5 whole Yellow Onions and the 6 whole Hard-Boiled Eggs (peeled). Mince the 0.25 cup Fresh Dill and 0.25 cup Fresh Chives separately—you'll add them at the end for freshness. Keep these in separate bowls until ready to mix.

In a large mixing bowl, combine the 1.5 cups Mayonnaise, 1 tbsp Dijon Mustard, 1 tbsp Apple Cider Vinegar, 1 tsp Granulated Sugar, 1.5 tsp Salt, and 0.5 tsp Black Pepper. Whisk until completely smooth—the dressing should be perfectly creamy with no lumps.

Here's the thing—this is where the magic happens. The vinegar brightens the mayo while the sugar balances the tang. Taste as you go and adjust seasoning if needed. You want it tangy but not sour, creamy but not heavy.

Cut the baked potatoes open lengthwise and scoop out the warm flesh into your mixing bowl with the dressing. Use a fork to break up any large chunks—you want even distribution. Add the chopped celery crowns, onions, and hard-boiled eggs, then gently fold everything together.

Real talk: Don't overmix or you'll mash the potatoes into oblivion. Just combine until the dressing coats everything evenly. The residual heat from the potatoes will help the flavors meld beautifully. If it looks dry, add a splash of milk or water to loosen it.

Transfer the salad to a serving bowl and sprinkle with the minced fresh dill and fresh chives. Add the 0.5 cup Crispy Bacon Bits if using—this is where the salad gets its extra flair. The contrast of crispy bacon against the creamy potatoes is pure perfection.

Serve immediately while the potatoes are still warm. Each bite should deliver that irresistible combination of creamy dressing, tender potatoes, crisp celery crowns, and fresh herbs. This isn't just potato salad—it's a celebration of textures and flavors!
