This crispy potato salad transforms the humble classic into something extraordinary by roasting the potatoes after boiling, creating an irresistible contrast between the crispy exteriors and creamy dressing. The combination delivers a potato salad that breaks all the rules in the best possible way.
I discovered this technique during a summer potluck disaster when I realized my standard potato salad needed something special. The crispy version received so many compliments that it's now my signature dish at every family barbecue.
Ingredients
- Yukon gold potatoes: Give you the perfect balance of starch and waxiness for crispy exteriors and creamy centers
- Olive oil: Helps potatoes achieve that golden exterior in the oven
- Garlic powder: Adds aromatic flavor without burning like fresh garlic would
- Sour cream: Provides tanginess and richness to the dressing
- Mayonnaise: Creates the creamy base that coats each potato perfectly
- Fresh scallions: Deliver mild onion flavor and beautiful color contrast
- Fresh dill: Brings its distinctive herbaceous flavor that pairs perfectly with potatoes
- Fresh parsley: Adds bright color and a clean peppery finish
- Dijon mustard: Adds complexity and helps emulsify the dressing
- Lemon juice: Cuts through the richness with necessary acidity
Step-by-Step Instructions
- Prepare the Potatoes:
- Start with cold water for even cooking and add salt to season the potatoes from within. Boiling them until just fork tender ensures they'll hold their shape during roasting while being fully cooked inside.
- Seasoning for Roasting:
- Gently toss the potatoes with olive oil and seasonings to ensure even coating without breaking them apart. The oil is crucial for developing that crispy exterior.
- Roast to Perfection:
- Arrange potatoes in a single layer with space between pieces to promote browning. The high temperature creates caramelization and texture contrast that makes this salad special.
- Create the Dressing:
- Combine all dressing ingredients while potatoes roast. This allows flavors to meld and develop while you wait, making the final dish more cohesive and flavorful.
- Reserved Garnish:
- Setting aside some herbs creates a beautiful presentation and adds a fresh flavor burst right before serving. This small step elevates the dish significantly.
- Final Assembly:
- Wait until serving time to combine potatoes with dressing to maintain maximum crispiness. The warm potatoes will slightly melt the dressing creating an incredible flavor marriage.

The first time I served this at a family gathering, my grandmother who rarely comments on new recipes asked for seconds and then the recipe. The combination of fresh dill with the crispy potatoes reminds me of the Swedish potato dishes from my childhood but with an American picnic twist.
Storage Tips
For maximum crispiness, store the roasted potatoes separate from the dressing in airtight containers in the refrigerator for up to 3 days. When ready to serve, allow potatoes to come to room temperature before combining with the dressing. If you've already mixed everything, the salad will still taste delicious but the potatoes will lose their crunch. Reheat leftover dressed potato salad in the oven at 350°F for 10 minutes to revive some texture.
Seasonal Variations
In summer, add fresh corn kernels and chopped cherry tomatoes to the finished salad for a farmers market twist. During fall, try mixing in some chopped apple and celery for extra crunch. Winter versions work beautifully with added crispy bacon and a sprinkle of smoked paprika. Spring calls for additional fresh herbs like chives and tarragon that complement the existing herb profile.
Make It A Meal
Turn this side dish into a complete meal by adding protein. Top with sliced grilled chicken, crumbled feta cheese, or hard boiled eggs for a satisfying lunch. For a vegetarian option, add roasted chickpeas or white beans. Serve alongside a simple green salad with vinaigrette for a perfect light dinner that requires minimal additional preparation.
