Baked Potato Sour Cream Salad Recipe: Crisp Celery Crowns Over Cool Creamy Bliss

This baked potato sour cream salad recipe delivers the perfect balance of crisp celery crowns and cool, creamy potato chunks—restaurant-quality without the fuss. The secret lies in baking the potatoes until tender yet firm, then tossing them with a tangy sour cream dressing that binds everything together.

I developed this version after years of perfecting the texture, ensuring each bite delivers that satisfying contrast of warm, fluffy potatoes and crisp vegetables.

The foundation of this salad is simple yet transformative: creamy sour cream blended with mayonnaise, mustard, and fresh herbs creates a dressing that clings beautifully to the potatoes.

The celery gets the crisp treatment by baking instead of boiling, which preserves its snap and adds a subtle sweetness that complements the earthy potatoes. This method also eliminates the need for soggy lettuce or wilted herbs—every ingredient stays vibrant until the very last bite.

What you'll end up with is a salad that's rich, satisfying, and packed with texture—creamy potato chunks, crisp celery, and just enough tang to keep it fresh. The dressing coats each potato perfectly, while the celery adds a satisfying crunch that makes every forkful exciting.

It's the kind of side dish that turns a simple picnic into a memorable meal, or elevates any summer gathering from ordinary to extraordinary.

Perfect for potlucks, BBQs, or a hearty side to grilled meats, this salad keeps well for 2-3 days in the refrigerator, making it ideal for meal prep. The flavors actually deepen over time, so it tastes even better the next day.

Let's get started on creating this crowd-pleasing classic that's sure to become a staple at your table.

Ingredients for baked potato salad recipe with sour cream

Six ingredients make this creamy, crisp potato salad shine—no soggy textures here.

The potatoes are everything. Russets are your best bet—they hold their shape when baked and stay fluffy. Grab the biggest ones you can find at Whole Foods or your local grocery store's organic section. Skip the waxy potatoes; they turn mushy. Celery needs to be crisp, so look for stalks with a vibrant green core—Trader Joe's usually has the freshest. Fresh herbs are non-negotiable here: the dill and chives add that bright, fresh note that makes this salad sing. If you're short on time, dried dill works at half the amount, but it won't be the same. For the sour cream, full-fat is a must—it's what gives this salad its signature richness.

No sour cream? Greek yogurt mixed with a splash of milk gets you close, but it won't be quite as creamy. Short on dill? Fresh parsley at double the amount works in a pinch, though it'll have a different flavor profile. The mayonnaise can be any good-quality brand—Hellmann's or Duke's are safe bets. For the vinegar, white or apple cider both work, but white keeps the flavor cleaner. The garlic can be roasted for a sweeter taste—just toss the minced cloves with a drizzle of olive oil and bake at 400°F for 10 minutes before adding to the dressing. If you're watching calories, you can reduce the mayo by half and add an extra tablespoon of Greek yogurt, but trust me on the full-fat version.

This salad tastes even better the next day—2-3 days in the fridge is perfect. Store it in an airtight container with a layer of plastic wrap pressed right on top to keep the celery from getting soggy. For serving, I like to sprinkle the green onions on top right before eating—they add a fresh pop of color and flavor. If you're making this ahead for a potluck, assemble everything except the celery crowns until the last minute. Bake the celery just before serving so it stays crisp. Leftovers? It reheats beautifully in the microwave—just add a splash of milk to restore creaminess.

Step-by-step instructions for creamy baked potato salad

Here's how to make this ultra-creamy, crisp-crowned potato salad that's perfect for picnics and potlucks.

Preheat your oven to 400°F and line two baking sheets with parchment paper. Scrub the 3 lb Russet Potatoes clean and pierce each with a fork in several places. Brush them lightly with 2 tbsp Olive Oil and sprinkle with ½ tsp Salt—this helps crisp the skin.

Arrange the potatoes on the baking sheets and bake for 45-50 minutes until they feel soft when squeezed gently. You want them fully cooked but not falling apart. Let them cool slightly before handling—they'll be hot! I like to let them sit for about 10 minutes before peeling, which makes the skins slip off easily.

While the potatoes bake, trim the 2 bunch Celery Stalks and cut each stalk into ½-inch thick slices. The key here is to keep them whole—no need to chop them small. Spread them on a separate baking sheet and drizzle with 1 tbsp Olive Oil, tossing gently to coat.

Roast the celery at 400°F for 15-20 minutes until the edges are deep golden brown and crispy. You're going for that perfect celery crown texture—almost like little celery chips. Watch them closely so they don't burn. Once done, transfer to a plate and let cool slightly before adding to the salad.

In a large mixing bowl, combine the 1.5 cups Sour Cream, 0.5 cup Mayonnaise, 2 tbsp Yellow Mustard, 1 tbsp White Vinegar, 1 tsp Salt, and 0.5 tsp Black Pepper. Mix well until smooth and creamy—this is your flavor foundation. I like to use a rubber spatula for this step to make sure everything gets fully incorporated.

Next, add the 2 cloves Garlic Cloves (minced), 0.25 cup Fresh Dill, and 0.1 cup Fresh Chives. Stir gently to fold in the herbs without breaking them down too much—you want those pretty green flecks throughout the salad. Taste the dressing and adjust seasoning if needed, adding more salt, pepper, or vinegar as desired.

Once your potatoes are cool enough to handle, cut them in half lengthwise and scoop out the flesh into a large bowl. I use a spoon to scrape out all that creamy potato goodness—don't worry about getting every last bit, but try to keep it chunky. Add the crisp celery crowns to the bowl along with the dressing mixture.

Gently fold everything together until the potatoes are fully coated in the creamy dressing. You want to mix just enough so the celery crowns stay intact and the potatoes maintain their texture. If the salad seems too thick, you can stir in 1-2 tablespoons of cold water or reserved potato water to loosen it up.

Cover the salad bowl and refrigerate for at least 2 hours (or up to 24 hours) to let the flavors meld together. This chilling time is crucial for developing that perfect creamy texture and letting all the flavors come together. The longer it chills, the better it gets!

Before serving, give the salad a final stir and garnish with the 3 whole Green Onion (sliced). The bright green color and mild onion flavor make a beautiful contrast to the creamy potatoes. Serve chilled and enjoy the perfect balance of crisp celery crowns and cool, creamy potato goodness!

Pro cooking tips for baked potato salad recipe with sour cream

Potato Baking Secrets

Always bake your Russet Potatoes at 400°F until they yield to gentle pressure but don't collapse. I pierce them with a fork first to prevent explosions, then brush with 2 tbsp olive oil and sprinkle with ½ tsp salt for crispy skins.

The 10-minute rest after baking makes peeling effortless—just slip off those skins while still warm. 🥔

Celery Crown Perfection

For crisp celery crowns, slice stalks into ½-inch thick rounds and roast at 400°F for 15-20 minutes until edges turn golden. Toss lightly with 1 tbsp olive oil and watch closely—they burn fast! Keep them whole for that satisfying crunch. 🧅

Dressing Balance

Your dressing ratio is key: 1.5 cups sour cream to 0.5 cup mayo creates the perfect creaminess. Add 2 tbsp Dijon mustard for tang and 1 tbsp vinegar for brightness. Fold in fresh herbs last to preserve their texture—no pulverizing! Taste as you go. 🥛

Texture Control

Keep potatoes chunky by scooping flesh with a spoon—no food processor! For extra creaminess, stir in 1-2 tbsp reserved potato water if needed. The 2-hour chill lets flavors meld while maintaining that perfect texture contrast. 💫

Make-Ahead Magic

Assemble this salad 24 hours ahead—flavors deepen overnight. Store in an airtight container with plastic wrap pressed against the celery to prevent sogginess. Reheat gently if needed, adding a splash of milk to restore creaminess. 📅
