Baked Potato Salad Recipe With Sour Cream: Creamy Chunky Picnic Classic

This baked potato salad delivers the creamy texture and rich flavor of a loaded baked potato in every bite.

I developed this recipe to capture the essence of a classic side dish while adding the comforting elements of a fully dressed baked potato. The potatoes are roasted until tender, then combined with a tangy sour cream dressing.

What makes this version special is the balance of flavors—smoky, crispy, and creamy all at once. It’s the perfect dish for picnics, potlucks, or a cozy family dinner.

You’ll love how the familiar flavors come together in a new way. Here’s how to make it.

Ingredients for Baked Potato Salad Recipe with Sour Cream

Everything you need for that loaded baked potato taste in a picnic-perfect salad.

The potatoes are the foundation here. Russets give you that classic baked potato texture—fluffy inside, crisp outside. Look for firm, dry skins without green spots (those taste bitter). Whole Foods or your local farmers market usually has the best selection. I roast mine with olive oil and salt until golden and tender, about 40 minutes at 400°F.

No sour cream? Greek yogurt at a 1:1 ratio works fine, but the tang won’t be quite the same. For a lighter version, low-fat sour cream is acceptable (just don’t tell anyone). The cheddar can be swapped for Colby Jack or Monterey Jack if that’s what you’ve got. Bacon haters can skip it entirely—sun-dried tomatoes add a nice chewy contrast if you want to keep it meat-free.

This salad keeps well, covered, in the fridge for 3-4 days. The flavors actually get better after a night in the cold. Don’t freeze it though—the potatoes turn mushy. Best served slightly chilled, not straight from the ice chest.

Step-by-Step Instructions for Baked Potato Salad With Sour Cream

Here’s the method I use to create this creamy, crowd-pleasing dish every time.

Step 1: Roast the Russet Potatoes to Perfection

Preheat your oven to 400°F. While it heats, toss the 2.5 lb Russet Potatoes with 2 tbsp Olive Oil, 1 tsp Salt, and 0.5 tsp Black Pepper in a large bowl. I make sure every cube is well coated—this ensures even browning and maximum flavor.

Spread the potatoes in a single layer on a baking sheet. Roast for 25-30 minutes, flipping halfway through, until they’re golden brown and crispy on the edges but still tender inside. Watch them closely toward the end—they should be fork-tender but not mushy. Let them cool completely before mixing with the dressing; hot potatoes will make it runny.

Step 2: Prepare the Creamy Dressing Base

In a large mixing bowl, combine the 1.5 cups Sour Cream and 0.5 cup Mayonnaise. I always use full-fat sour cream for that ultra-creamy texture it promises. Whisk until smooth—this is your foundation for the rich, tangy dressing that makes this dish special.

Add the 1 tbsp Dijon Mustard, 1 tbsp Apple Cider Vinegar, 1 tsp Garlic Powder, and 1 tsp Onion Powder. Stir well to combine. The vinegar cuts through the richness, while the mustard adds a subtle tang that balances the creaminess perfectly. Taste and adjust seasoning if needed before adding the potatoes.

Step 3: Combine All Ingredients Gently

Once the potatoes have cooled, add them to the bowl with the dressing. I pour them in while they’re still just warm to the touch—this helps them absorb the flavors better. Gently fold everything together with a spatula, being careful not to break up the potato chunks too much. You want that rustic, chunky texture.

Stir in the 1 cup Sharp Cheddar Cheese, 0.5 cup Green Onions, and 2 tbsp Chives. The cheese should be shredded from a block for the best melt and texture. I save a handful of cheese and a sprinkle of green onions to use as garnish later for a beautiful presentation.

Step 4: Chill and Add the Final Touches

Cover the bowl and refrigerate for at least 1 hour. This chilling time allows the flavors to meld together beautifully. I’ve found that overnight chilling makes it taste even better, so I often make it the day before serving.

Just before serving, give it a good stir and taste again. If needed, adjust the seasoning with a bit more salt or pepper. Sprinkle the reserved cheese and green onions on top, then add the 0.5 lb Cooked Bacon crumbled over the surface. The bacon adds a smoky crunch that takes this dish to the next level, and it stays crispy when added last.

Best Sauces and Condiments for This Recipe

Classic Toppings

For that true loaded baked potato feel, I always keep extra sharp cheddar cheese and crumbled bacon on hand for garnishing. The combination of melted cheese and crispy bacon on top takes this salad to the next level. 💛

Fresh Herb Boost

Fresh herbs add brightness to the creamy dish. I love sprinkling extra chives or green onions just before serving. A handful of chopped fresh dill adds a refreshing contrast that balances the richness beautifully.

Tangy Additions

A drizzle of hot sauce like Tabasco or a spoonful of pickled jalapeños cuts through the creaminess with a spicy kick. I also recommend adding 1-2 tbsp of the potato cooking liquid to the dressing for extra depth.

Crunchy Elements

For texture, add ½ cup crushed potato chips or buttered breadcrumbs right before serving. The crunch contrasts perfectly with the creamy potatoes. I’ve also used toasted pepitas for a nutty twist.

Sauce Enhancements

A swirl of sriracha mayo or chipotle cream sauce adds a smoky dimension. I mix 2 tbsp mayo with 1 tsp adobo sauce from canned chipotles for an easy upgrade. 🔥

Fresh Veggie Crunch

Diced celery or bell peppers add color and crunch. I fold in ½ cup finely diced celery with the potatoes for a subtle freshness that doesn’t overpower the dish.
