Side Dishes
A baked potato salad with sour cream transforms a classic side into something creamy, herby, and irresistibly tender. The secret lies in baking the potatoes until fork-tender—never mushy—so they absorb the rich sour cream dressing without falling apart.
This isn’t your grandmother’s dry salad; it’s a velvety, herb-packed dish with crisp celery crowns for texture that holds up for potlucks or picnic spreads.
Start by baking russet potatoes until their edges crisp and centers yield to a fork—a process that takes about 45 minutes at 400°F. While they cook, mix together sour cream, mayo, Dijon mustard, and a blend of fresh chives, parsley, and dill for bright, layered flavor.
The chilling step (at least 2 hours) lets the flavors meld and the potatoes soak up the dressing just right, ensuring every bite is creamy and cohesive.
What sets this recipe apart is the celery crown crunch—thinly sliced celery tossed in a touch of vinegar and lemon zest before mixing in. It adds a refreshing bite that cuts through the richness, while optional add-ins like crispy bacon or crumbled blue cheese elevate it for special occasions.
The result? A salad so satisfying, it’ll disappear faster than you can say "second helping."
Perfect for summer gatherings, game days, or as a hearty side to grilled meats, this baked potato salad delivers restaurant-quality comfort without the fuss. Let’s get started—your taste buds (and leftovers) will thank you.
Ingredients for baked potato salad recipe with sour cream
Six creamy ingredients plus crispy celery crowns—this salad is anything but basic.
| Ingredient | Amount | Notes |
|---|---|---|
| Russet Potatoes 🥔 | 3 lb | Medium size, scrubbed clean |
| Sour Cream 🥛 | 1 cup | Full-fat for best creaminess |
| Mayonnaise 🍳 | ½ cup | Dijon-infused preferred |
| Fresh Chives 🌿 | ¼ cup | Finely chopped, stems removed |
| Fresh Parsley 🌿 | ¼ cup | Flat-leaf, finely chopped |
| Fresh Dill 🌿 | 0.15 cup | Finely chopped, stems removed |
| Dijon Mustard 🍯 | 1 tbsp | For tangy depth |
| Celery Stems 🧅 | 2 whole | Thinly sliced, crowns only |
| White Vinegar 💧 | 1 tbsp | For celery crunch |
| Lemon Zest 🍋 | 1 tsp | Freshly grated |
| Salt 🧂 | 1 ½ tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ½ tsp | Freshly ground |
| Crispy Bacon 🥓 | 4 oz | Optional, crumbled |

Russets are your best bet—their fluffy texture soaks up the dressing like a dream. Store-bought pre-washed saves time, but scrubbing them yourself ensures no dirt hides under the skin. For even baking, poke them with a fork first—400°F for 45 minutes until fork-tender is key. The sour cream is non-negotiable here; full-fat gives that velvety richness, while low-fat turns it into sad, watery dressing. If you're short on time, Trader Joe's sells pre-cooked baby potatoes that work in a pinch—just halve them before baking.
No fresh herbs? Dried chives and parsley at half the amount get you close, but fresh is worth hunting down at the grocery store's produce section—look for vibrant green leaves, not wilted ones. The celery crowns are the secret weapon—slice them thinly (a mandoline makes this easy) and toss with vinegar and lemon zest immediately before mixing. That acidity keeps them crisp. For the mustard, Dijon adds complexity, but yellow mustard works if that's all you've got. Bacon lovers, cook it crispy first—it'll soften when mixed in, but you want that crunch to stay.
This salad tastes even better the next day—chill for at least 2 hours before serving. Store leftovers in an airtight container with a layer of plastic wrap pressed right on top to keep the potatoes from drying out. Keeps 4-5 days in the fridge, though I rarely have any left that long. For potlucks, portion it into individual containers—celery crowns stay crispest when served fresh, so add those last minute. Freezes surprisingly well too, though texture changes slightly after thawing.

Step-by-step instructions for herb-packed baked potato salad
Here's how to make creamy, herby potato salad with a perfect crunchy celery crown finish.
🍳 Step 1: Bake the Potatoes Until Fork-Tender
Preheat your oven to 400°F and line a large baking sheet with parchment paper. Pierce each of the 3 lb Russet Potatoes with a fork 4-5 times to allow steam to escape. Place them directly on the baking sheet and bake for 45-50 minutes until a knife slides in easily with just slight resistance.
I like to rotate the pan halfway through baking for even browning. The potatoes should feel soft when squeezed gently at their thickest point. Let them cool slightly before handling—they'll be hot! This baking method keeps them fluffy and prevents the salad from becoming watery later.
👨🍳 Step 2: Prepare the Celery Crown Crunch Mix
While the potatoes bake, slice the 2 whole Celery Stems thinly on a diagonal, keeping only the crisp crown portions. In a small bowl, combine the celery with 1 tablespoon White Vinegar and toss gently. Let this sit for 5 minutes—this preserves the celery's crisp texture and adds a pleasant tang.
Add the 1 tablespoon Dijon Mustard and 1 teaspoon Lemon Zest to the celery mixture. This combination brightens the flavors and prevents the celery from becoming soggy. Set this aside while you make the creamy base—it'll be ready to fold in at the perfect moment.
🥘 Step 3: Create the Creamy Herb Base
In a large mixing bowl, combine the 1 cup Sour Cream and 0.5 cup Mayonnaise using a rubber spatula. Whisk in the 1.5 teaspoons Salt and 0.5 teaspoon Black Pepper until fully incorporated. This is where the magic happens—the sour cream adds tang while the mayo provides that classic creamy texture.
Gently fold in the 0.25 cup Fresh Chives, 0.25 cup Fresh Parsley, and 0.15 cup Fresh Dill. I like to use a folding motion with the spatula to keep the herbs evenly distributed without crushing them. The herbs should be finely chopped but still visible—this gives the salad that fresh, vibrant flavor in every bite.
⏰ Step 4: Assemble and Chill for Perfect Texture
Once your potatoes are cool enough to handle, cut them into 1-inch chunks (no need to peel them—the skins add texture). Add them to the herb mixture and gently fold until every potato piece is coated. Fold in the celery crown mixture last, reserving a few pieces for garnish if desired.
If using, crumble the 4 oz Crispy Bacon and fold it in now for extra savory depth. For a tangy twist, sprinkle in the 0.25 cup Blue Cheese Crumbles and gently stir. Cover the bowl and refrigerate for at least 2 hours, or up to overnight. This chilling time lets the flavors meld beautifully and ensures the perfect creamy consistency.
🍽️ Step 5: Serve with Fresh Garnishes
Before serving, give the salad one final gentle fold to redistribute any settled ingredients. Taste and adjust seasoning if needed—sometimes the potatoes absorb more salt than expected. Transfer to a serving bowl and garnish with the reserved celery pieces and any remaining fresh herbs.
This potato salad keeps well for 3-4 days in the refrigerator, making it perfect for meal prep. The flavors actually improve as it sits, with the herbs releasing more aroma and the celery maintaining its crispness. Serve it at room temperature for the best texture and enjoy the perfect balance of creamy, herby, and crunchy elements in every bite.
Pro Tips For Making Baked Potato Salad Recipe With Sour Cream
- BOIL UNTIL FIRM: Russets stay gluey if you undercook them—test with a fork, not just time. Aim for 15-18 minutes in salted boiling water, then let them cool in the pot for 10 minutes before handling. I learned this the hard way after mashing a batch that turned into potato pudding.
- CHOP CHIVES LAST: Fresh chives lose their bright color and crispness if soaked in dressing too long. Fold them in just before serving, or sprinkle them on top as a garnish. This keeps their flavor sharp and the salad looking fresh.
- DON’T SKIP THE ICE BATH: After boiling, plunge the potatoes into an ice water bath for 5 minutes. This stops the cooking process and prevents them from turning gummy when mixed with sour cream. Trust me, your salad will thank you later.
- BALANCE CREAMY TEXTURES: Too much sour cream makes the salad heavy; too little mayo makes it dry. Start with a 1:1 ratio of mayo to sour cream, then adjust based on your potatoes’ moisture. If they’re extra wet, add a splash of Greek yogurt for tang without bulk.

Frequently asked questions about creamy baked potato salad
Why does my baked potato salad turn watery?
The most common cause is overcooking the potatoes—they release too much moisture when boiled. Baking them until fork-tender (not mushy) prevents this. Also, avoid adding cold potatoes to warm dressing; let everything cool first. For extra insurance, chill the salad for 2+ hours before serving.
Can I make this salad ahead of time?
This salad actually tastes better the next day as flavors meld. Store in an airtight container with plastic wrap pressed directly on the surface to prevent drying. Keep it refrigerated for up to 5 days. Just give it a gentle stir before serving and add fresh celery crowns for crunch.
What's the best way to keep celery crowns crisp?
Toss them with 1 tbsp vinegar and 1 tsp lemon zest immediately before mixing into the salad. The acidity preserves their texture. For extra crunch, slice them just before serving and store separately. If your celery softens after mixing, add a pinch of salt and a splash of cold water to revive it.
Can I substitute Greek yogurt for sour cream?
Yes, but use ¾ cup full-fat Greek yogurt instead of 1 cup sour cream for similar creaminess. Add 1 tsp lemon juice to balance tanginess. The texture will be slightly lighter but still delicious. For best results, let the salad chill longer (up to 4 hours) to thicken properly.
How do I make this salad spicier?
Add ½-1 tsp cayenne pepper or 1 tbsp hot sauce to the dressing. For depth, fold in 1 tbsp chipotle powder or 2 tbsp pickled jalapeños** (chopped). For heat lovers, top with sriracha drizzle or crumbled chorizo before serving. Adjust to taste!
