Ingredients for baked potato salad recipe with sour cream
These 13 ingredients deliver the perfect creamy, crispy potato salad magic you've been craving.
| Ingredient | Amount | Notes |
|---|---|---|
| Russet Potatoes 🥔 | 3 lb | Medium size, baked whole |
| Sour Cream 🧀 | 1 ½ cups | Full-fat for creaminess |
| Greek Yogurt 🥛 | ½ cup | Plain, full-fat preferred |
| Yellow Onion 🧅 | 1 whole | Medium size, finely diced |
| Celery Stalks 🥬 | 3 whole | Fresh, crisp variety |
| Dijon Mustard 🍋 | 2 tbsp | For tangy depth |
| Mayonnaise 🥫 | ¼ cup | Light mayo for balance |
| Fresh Dill 🌿 | ¼ cup | Chopped, for brightness |
| Salt 🧂 | 1 ½ tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ½ tsp | Freshly ground preferred |
| Butter 🧈 | 2 tbsp | Unsalted, for celery sear |
| Lemon Juice 🍋 | 1 tbsp | Freshly squeezed |
| Chives 🌱 | 2 tbsp | Chopped, for garnish |
The potatoes are the foundation, so Russet potatoes are your best bet—they're waxy enough to hold shape but fluffy when baked. Buy them fresh (within a week of harvest) for the best texture, and avoid those sprouting eyes. I always grab mine from Whole Foods or the organic section at Kroger—they're worth the few extra cents. For the celery, look for stalks that are crisp and bright green, not rubbery or yellowing. The full-fat sour cream is non-negotiable here—it's what gives this salad that signature velvety texture without being heavy. Trust me on this one, even if you're watching calories.
No full-fat sour cream? Plain Greek yogurt mixed with a splash of milk gets you close, though the texture will be slightly lighter. Short on celery? Green bell pepper works perfectly—same crunch, different flavor profile. The Dijon mustard can be swapped for regular yellow mustard, but you'll lose some depth. For the butter, margarine works in a pinch, though it won't have the same rich flavor. The lemon juice is key for brightness—bottled lemon juice works, but fresh is always better. And if you're prepping ahead, keep the celery and potatoes separate until mixing to maintain that all-important crunch.
This salad tastes even better the next day as the flavors meld. Store the dressing components (sour cream, yogurt, mustard, mayo) in one container and the potatoes/veggies in another—mix just before serving. Keeps for 4 days in the fridge. For meal prep, I portion it into individual containers with the celery on top so everyone can add their own crispy bite. The dressing can be made 3 days ahead—just stir before using. And if you're serving a crowd, double the batch—it disappears fast!

Step-by-step instructions for baked potato salad with sour cream
This method delivers that perfect balance of creamy richness and satisfying crunch every time.
Bake Potatoes Until Fork-Tender
Preheat your oven to 400°F. Scrub the 3 lb Russet Potatoes clean and prick each with a fork in several places to allow steam to escape. Place them directly on the oven rack or on a baking sheet for even browning. Bake for 60-75 minutes until completely tender when pierced with a fork.
Here's the thing—don't skip the fork test. You want them soft enough that a fork slides in easily with no resistance. If they're still firm in the center, give them another 15-20 minutes. The potatoes should be fluffy inside with crispy skin. Let them cool slightly before handling, about 10 minutes, but don't let them get cold.
Prepare the Creamy Base
In a large mixing bowl, combine the 1.5 cups Sour Cream, 0.5 cup Greek Yogurt, 2 tbsp Dijon Mustard, 0.25 cup Mayonnaise, 1.5 tsp Salt, and 0.5 tsp Black Pepper. Whisk together until smooth and fully combined. The mixture should be thick but still pourable.
This is where the magic happens—I like to add the 1 tbsp Lemon Juice now to brighten the flavors before mixing in the fresh herbs. The acidity balances the richness of the sour cream and mayo. Give it one final stir to make sure everything's evenly distributed before adding the vegetables.
Sear and Dice Celery for Crispy Bites
Heat a large skillet over medium heat and melt the 2 tbsp Butter. Add the 3 whole Celery Stalks, cut into ¼-inch dice, and cook for 5-6 minutes, stirring occasionally, until the edges turn golden brown. This step creates those crispy celery bits that add texture contrast.
Don't walk away during this step. You want the celery to develop color but not burn. It should be tender-crisp with slightly caramelized edges. Transfer the cooked celery to a cutting board and let it cool for 2 minutes before adding to the salad. The residual heat will continue cooking it slightly when mixed in.
Combine All Ingredients
Cut the cooled potatoes in half lengthwise and scoop out the flesh into your mixing bowl with the cream base. Add the seared celery, 1 whole Yellow Onion finely diced, and 0.25 cup Fresh Dill chopped. Gently fold everything together using a spatula or wooden spoon until fully incorporated.
This is where patience pays off. Don't overmix—just combine until everything is evenly distributed. The potatoes should be coated in the creamy dressing with no dry spots. If the salad seems too thick, you can add a splash of milk or potato water to reach your desired consistency.
Chill and Garnish
Cover the salad and refrigerate for at least 2 hours, preferably 4 hours, to allow the flavors to meld together. The chilling time is crucial for developing that perfect creamy texture and letting all the flavors come together.
Before serving, give the salad one final taste and adjust seasoning if needed. Garnish with 2 tbsp Chives chopped and serve chilled. The contrast of the cool, creamy salad with those crispy celery bits is what makes this dish truly special. Enjoy it as a side dish or even as a main course with some crusty bread!
Pro Tips For Making Baked Potato Salad Recipe With Sour Cream
- Boil Potatoes Until Fork-Tender: I learned this the hard way—undercooked potatoes turn to mush when dressed. Boil Russets in salted water until you can pierce them with a fork without resistance, then let them cool in the pot with cold water for 10 minutes. That pause keeps them from falling apart when chopped.
- Chop Onion and Celery Small: The texture of this salad hinges on even distribution. Dice the yellow onion and celery into 1/4-inch pieces—no bigger, or you’ll get crunchy surprises. If you’re impatient, pulse them in a food processor, but don’t overdo it; you want texture, not paste.
- Mix Dressing Last, Gently: Adding sour cream and Greek yogurt too soon makes the potatoes soggy. Wait until everything’s cooled, then fold in the dressing with a rubber spatula—just until combined. Overmixing turns the salad into a clumpy mess, and under-mixing leaves dry spots. Aim for a "just combined" look.
- Use Full-Fat Sour Cream: I was skeptical until I tried it: full-fat sour cream adds richness and prevents the salad from tasting watery. Skip the low-fat version—it separates and makes the whole dish taste flat. If you’re watching calories, at least mix in a little mayo for stability.
Make-ahead tips for this dish
Prep Ahead Strategy
I always make the dressing components 3 days ahead—just whisk the sour cream, Greek yogurt, mustard, mayo, salt, and pepper together, then store in an airtight container.
The flavors develop beautifully over time, and it saves you from mixing everything last-minute. Keep the potatoes and celery separate until ready to assemble. 🧀
Potato Prep Timeline
Bake the potatoes the night before and store them at room temperature in a paper bag for up to 24 hours. This makes them easier to scoop later and gives you a head start.
If you're really planning ahead, you can even bake them 2 days ahead—just reheat in the microwave for 1-2 minutes before scooping to restore some moisture.
Celery Storage Hack
For maximum crunch, store the celery stalks in a sealed container with a damp paper towel. This keeps them crisp for 5-6 days in the fridge.
When ready to use, just dice and sear them fresh—no soggy celery here! I swear by this trick for maintaining that perfect crisp-tender texture. 🥬
Assembling for Serving
Keep the celery and potatoes separate until the very last minute. Mix the dressing with the potatoes first, then fold in the crispy celery just before serving. This ensures every bite has that satisfying crunch.
For large gatherings, I portion the salad into individual containers with the celery on top—guests can add their own crispy bites as they eat.
Make-Ahead Serving Suggestions
This salad actually tastes better the next day as the flavors meld together. Store the fully assembled salad (without celery) in an airtight container for up to 4 days. When ready to serve, simply add the freshly seared celery and garnish with chives.
The contrast of cool, creamy salad with warm, crispy celery is what makes this dish shine at picnics and potlucks.
Freezer-Friendly Option
For longer storage, you can freeze the dressing portion (without celery or potatoes) for up to 3 months. Thaw overnight in the fridge before using. When ready to assemble, bake fresh potatoes and add the thawed dressing.
Just add the celery fresh to maintain that essential crunch. This is my go-to for holiday meal prep! ❄️

Frequently asked questions
Why does this recipe use baked potatoes instead of boiled?
The baking method creates a more tender, fluffy texture that holds up better in the creamy dressing without turning mushy. Baked potatoes also develop a slightly crispy skin that adds an extra layer of texture contrast, making every bite more satisfying than boiled potatoes would provide.
Can I make this salad ahead of time?
The fully assembled salad (without celery) keeps well in the fridge for 4 days. For best results, store the dressing components separately from the potatoes and mix just before serving. Add the crispy celery fresh to maintain that perfect crunch. The flavors actually develop beautifully overnight!
What if I don't have fresh dill?
No problem! You can substitute with 1 tbsp dried dill or even 1 tbsp chopped parsley for a slightly different but still bright flavor. For a more robust taste, try 1 tsp dried tarragon—it pairs wonderfully with the sour cream and potatoes. Just reduce any other herbs you're using to maintain balance.
How do I keep the celery crispy?
Sear the celery in butter until golden brown (about 5-6 minutes) and add it to the salad just before serving. For extra crunch, store celery stalks in a sealed container with a damp paper towel in the fridge—this keeps them crisp for 5-6 days. Never add celery to the salad more than 30 minutes before eating.
Can I make this salad without mayo?
Yes! Simply reduce the sour cream to 1 cup and increase the Greek yogurt to 1 cup for a lighter, tangier version. The recipe already uses a mayo-light approach, so this swap keeps it creamy while cutting back on richness. For extra protein, stir in 0.5 cup crumbled bacon or 0.5 cup shredded rotisserie chicken.
