Salads
This baked potato salad recipe with sour cream delivers the perfect balance—crispy celery crowns floating over a velvety herb-sour cream base. The secret lies in roasting the potatoes until tender yet firm, then topping them with a creamy dressing that clings to every bite.
I developed this version after years of testing, ensuring the texture stays creamy without turning soggy, and the celery adds satisfying crunch.
What sets this recipe apart is the technique: warm potatoes absorb the dressing better than cold ones, creating a harmonious blend of flavors. You'll start with classic boiled or roasted potatoes, then mix in a tangy sour cream base with mustard, herbs, and a touch of mayo for richness.
The celery, chopped fine and crisped in butter, becomes the star topping that elevates every forkful.
The result is a salad that's hearty enough for a main dish but light enough for a side—ideal for picnics, potlucks, or summer gatherings. The sour cream keeps it luscious, while the celery adds a refreshing contrast.
Whether you serve it warm or chilled, this recipe delivers restaurant-quality texture and flavor without the fuss.
Optional add-ins like crispy bacon or fresh chives let you customize it to your taste. Ready in about 45 minutes, this potato salad is the ultimate crowd-pleaser. Let's get started!
Ingredients for baked potato salad recipe with sour cream
Pantry staples plus fresh herbs and crunchy celery—everything you need for creamy, restaurant-style potato salad.
| Ingredient | Amount | Notes |
|---|---|---|
| Russet Potatoes 🥔 | 3 lb | Medium size, scrubbed clean |
| Celery Stalks 🧅 | 3 whole | Fresh, crisp variety |
| Sour Cream 🥛 | 1 ½ cups | Full-fat for creaminess |
| Mayonnaise 🥫 | ½ cup | Duck or avocado oil preferred |
| Yellow Mustard 🌶️ | 2 tbsp | Dijon for extra tang |
| Fresh Dill 🌿 | ¼ cup | Chopped, stems removed |
| Fresh Chives 🌱 | ¼ cup | Finely chopped, for garnish |
| Red Onion 🧅 | 1 whole | Thinly sliced, pickled option |
| Unsalted Butter 🧈 | 2 tbsp | For crisping celery |
| Salt 🧂 | 1 ½ tsp | Kosher or sea salt |
| Black Pepper 🌶️ | 1 tsp | Freshly ground preferred |
| Garlic Cloves 🧄 | 2 cloves | Minced for dressing |
| White Vinegar 💧 | 1 tbsp | For pickling onions |
| Granulated Sugar 🍬 | 1 tsp | For pickling balance |
The potatoes are the foundation, so grab Russet potatoes—they hold up best to baking and roasting. Trader Joe's or Costco usually have them pre-washed, which saves time. If you're making this ahead, bake the potatoes the night before and reheat them gently before mixing. The celery? Look for bright green stalks with no brown spots—those crispy crowns are what make this salad special. I always buy extra because I use half for this recipe and half for soups.
No fresh dill? Dried dill at one-third the amount works in a pinch, but honestly, fresh makes all the difference. Short on sour cream? Greek yogurt gives a tangy twist—just add a splash of lemon juice to balance. The mayo can be light if you're watching calories, but full-fat keeps it ultra-creamy. For the pickled onions, mix the vinegar, sugar, and salt together, let it sit for 10 minutes, then pour over the onions. No pickling time? A quick splash of vinegar on the raw onions works too.
This salad tastes even better the next day—make a double batch and store leftovers in the fridge for up to 4 days. The dressing clings better to warm potatoes, so reheat gently before serving. For crispy celery crowns, toast them in butter for just 2-3 minutes until golden. Freeze extras in portions for quick meals—just add fresh herbs when reheating.

Step-by-step instructions for baked potato salad with sour cream
Here's how to make a showstopping potato salad with crispy celery crowns and ultra-creamy dressing.
Bake Potatoes Until Fork-Tender
Preheat your oven to 425°F and line a baking sheet with parchment paper. Pierce each of the 3 lb russet potatoes all over with a fork—this prevents them from exploding while baking. Place them directly on the baking sheet (no need for oil) and bake for 60-75 minutes until completely tender when pierced with a knife.
I like to test doneness by gently squeezing—if the skin gives slightly and a knife slides in easily, they're ready. Let them cool for 10 minutes before handling, then cut each potato in half lengthwise and scoop out the flesh into a large mixing bowl. You should have about 6 cups of potato flesh. Don't skip this cooling step—warm potatoes make the salad watery.
Crisp the Celery Crowns Perfectly
While the potatoes bake, wash and trim the 3 whole celery stalks, cutting off the leafy tops. Melt 2 tbsp unsalted butter in a large skillet over medium heat. Add the celery stalks cut-side down and cook for 5-6 minutes until the cut surfaces are deep golden brown and crispy. Flip and cook another 3-4 minutes until evenly browned.
Here's the thing—don't walk away. Celery burns fast once it starts browning. Remove from heat and let cool for 5 minutes before chopping into ¼-inch slices with a sharp knife. The crispy texture is what makes this salad special, so handle them carefully to maintain that crunch.
Make the Creamy Herb Dressing
In a separate bowl, combine the 1.5 cups sour cream, 0.5 cup mayonnaise, 2 tbsp Dijon mustard, 2 cloves minced garlic, 1.5 tsp salt, and 1 tsp black pepper. Mix until completely smooth—this is your base. Then fold in the 0.25 cup chopped fresh dill and 0.25 cup chopped fresh chives, reserving a little for garnish.
The dressing should be thick but pourable. If it's too thick, add 1-2 tablespoons of the potato water from the mixing bowl to loosen it. Taste and adjust seasoning—this is where the magic happens. The dressing should be tangy, herby, and perfectly balanced between creamy and slightly sharp.
Combine and Pickle the Onions
Add the scooped potatoes to the dressing and gently fold together using a large spoon. Be careful not to mash the potatoes—you want some texture. Stir in the crispy celery slices and set aside. For the onions, thinly slice the 1 whole red onion and place in a small bowl. Add 1 tbsp white vinegar, 1 tsp granulated sugar, and ½ tsp salt, mixing well. Let sit for 15 minutes to pickle.
This pickling step keeps the onions crisp and adds a nice tangy contrast to the creamy salad. The sugar balances the vinegar, so don't skip it. While the onions pickle, give the salad one final taste and adjust seasoning if needed—this is your last chance to perfect the flavor.
Chill and Serve with Crispy Garnish
Cover the salad bowl and refrigerate for at least 2 hours (overnight is even better). The flavors will meld beautifully, and the potatoes will absorb the dressing perfectly. Before serving, drain the pickled onions and sprinkle them over the top along with the reserved fresh chives. The contrast of crispy onions and celery against the creamy potatoes is what makes this salad special.
Serve chilled with a side of crusty bread or a simple green salad. The texture should be a perfect balance—creamy from the dressing, crisp from the celery and onions, and tender from the baked potatoes. This isn't your grandma's potato salad—it's a restaurant-worthy dish that'll impress everyone at your table.
Pro Tips For Making Baked Potato Salad Recipe With Sour Cream
- TEST THE POTATOES FIRST: Russet potatoes vary wildly—some are mealy by 50 minutes, others need 70. Pierce two with a fork, then bake at 400°F (200°C) until they give slightly when squeezed. Overcooked potatoes turn to mush in the salad, and no one wants that sad, gluey texture.
- SALT THE BOILING WATER: I learned this the hard way—skipping salt makes the potatoes absorb too much water, leading to a watery salad. Use a full tablespoon of salt in the boiling water, and don’t drain them until they’re just cool enough to handle. The starch clings to the potatoes longer, keeping the salad creamy and not sad.
- CHILL THE SALAD LONG ENOUGH: Cutting celery and mixing the dressing right after baking is tempting, but resist. Let the potatoes cool completely (at least 30 minutes) before tossing with sour cream and mayo. Warm ingredients thin the dressing, and you’ll end up with a runny mess—no one wants to eat soup for dinner.
- DRESS IT IN STAGES: Don’t dump all the sour cream and mayo at once. Start with half the dressing, mix gently, then taste. Add the rest gradually—this keeps the texture light and prevents a heavy, cloying flavor. My grandmother swore by this, and she was right: patience here makes a real difference.
Pro cooking tips for this recipe
Potato Texture Secrets
Baked potatoes are the foundation, so never skip the 10-minute cooling step after baking—they should be warm, not hot, when mixing. If they're too hot, the dressing will release moisture and make your salad watery.
I like to bake mine at 425°F until they're fork-tender but still hold their shape. For extra tenderness, pierce them with a fork before baking to prevent explosions. 🥔
Celery Crisp Perfection
Celery crowns are the star topping, so crisp them just right—5-6 minutes per side in butter over medium heat. Watch closely after the first 3 minutes, as celery burns quickly once it starts browning.
Let them cool for 5 minutes before chopping to maintain that perfect crunch. A sharp knife makes all the difference—use a chef's knife for clean, even slices. 🧅
Dressing Balance
The dressing is where the magic happens: 1.5 cups sour cream gives richness, while 2 tbsp Dijon mustard adds tang. For extra depth, add 2 minced garlic cloves and 1 tsp black pepper.
If the dressing is too thick, loosen it with 1-2 tbsp potato water—never milk or water, as it can make the salad taste flat. Taste as you go and adjust seasoning before mixing with the potatoes. ✨
Pickling Onions Right
Thinly sliced red onions need 15 minutes in a vinegar-sugar-salt brine to soften and pickle properly. The 1 tsp sugar balances the 1 tbsp vinegar, so don’t skip it—this step keeps the onions crisp and adds a bright tang.
Drain them well before adding to the salad to avoid sogginess. For a quicker version, toss raw onions with just 1 tsp vinegar and let sit for 10 minutes. 🧅
Chilling for Flavor
Refrigerate the salad for at least 2 hours (overnight is ideal) to let flavors meld. The potatoes absorb the dressing better when chilled, resulting in a creamy, cohesive texture.
Before serving, sprinkle with pickled onions and fresh chives for color and crunch. The contrast of warm, creamy potatoes with crisp toppings is what makes this salad shine. ❄️
Make-Ahead Mastery
This salad tastes even better the next day—double the batch and store leftovers in an airtight container for up to 4 days. The flavors deepen over time, and the potatoes stay tender.
To reheat, warm gently in the microwave or on the stovetop with a splash of water. For extra crispiness, toast fresh celery crowns before serving. 💡

Frequently asked questions
Can I use boiled potatoes instead of baked ones?
Yes, but baked potatoes give the best texture! Boiled potatoes work in a pinch, but they'll make the salad slightly waterier. For perfect results, bake them at 425°F until fork-tender—this keeps them creamy without being mushy. If using boiled, drain well and pat dry before mixing.
How do I make this salad ahead of time?
This salad tastes even better the next day! Assemble everything except the crispy celery crowns and pickled onions, then refrigerate for up to 4 days in an airtight container. Add the crisp toppings fresh before serving to maintain that satisfying crunch. The flavors meld beautifully overnight.
What if I don't have fresh dill?
No problem! Use 1 teaspoon dried dill (about 1/3 the fresh amount) or substitute with a mix of 1/4 cup parsley and 1/4 cup chives for a similar fresh flavor. The herbs are key for brightness, so don't skip them entirely. A pinch of lemon zest also adds great depth if you're feeling adventurous.
Can I make this salad without mayo?
For a lighter version, replace the mayo with 1/4 cup Greek yogurt plus 1 tablespoon lemon juice to balance the tang. The sour cream will still provide creaminess while keeping it dairy-free friendly. For extra richness, stir in 1 tablespoon melted butter instead of mayo.
Why does my celery turn mushy instead of crispy?
Celery loses crispness when overcooked or chopped too soon. Cook it in butter over medium heat for exactly 5-6 minutes per side** until golden brown, then let cool completely before chopping. Use a sharp knife and handle gently—celery's water content makes it fragile. For extra insurance, add a pinch of salt to the butter to help draw out moisture.
