If there’s one dish that disappears first at every summer cookout, it’s onion dip.

Creamy, savory, packed with sweet onion flavor, and impossible to stop eating—it has been a party favorite for decades. So I couldn’t help but wonder…what if you transformed those nostalgic flavors into the ultimate potato salad?

Instead of the traditional boiled potatoes, this version starts with crispy smashed Yukon Gold potatoes roasted until beautifully golden with irresistibly crunchy edges. They’re tossed in a creamy French onion-inspired dressing made with tangy Greek yogurt, sour cream, a touch of mayonnaise, and plenty of sweet caramelized onions.

The finishing touches are what take this potato salad over the top: crispy shallots for crunch, fresh chives and dill for brightness, and plenty of cracked black pepper.

It’s everything you love about classic onion dip and crispy kettle chips—but reimagined into a side dish that’s guaranteed to steal the show at your next barbecue, picnic, or Fourth of July celebration.

What Makes This Potato Salad Different?

Traditional potato salads are soft and creamy throughout.

This one is all about contrast.

Every bite combines crispy roasted potatoes with a silky onion dip-inspired dressing, buttery caramelized onions, crunchy shallots, and fresh herbs.

The potatoes soak up just enough dressing while keeping their crispy edges intact, creating layers of texture that make every forkful better than the last.

It’s comforting, nostalgic, and just elevated enough to feel like something you’d order at your favorite neighborhood restaurant.

G’s Tips For The Best Potato Salad

Roast Until Deeply Golden

Don’t rush the roasting step. The darker, crispier edges are what make this salad so special.

Use Yukon Gold Potatoes

Their naturally buttery texture holds together beautifully after smashing and roasting.

Caramelize the Onions Slowly

Low and slow is the secret. As the onions cook, their natural sugars develop into a rich, sweet flavor that gives the dressing its signature French onion taste.

Toss While the Potatoes Are Warm

Warm potatoes absorb the dressing more effectively, giving every bite extra flavor while still staying crisp.

Make Ahead Tips

The caramelized onions and dressing can be prepared up to two days in advance.
For the best texture, roast the potatoes just before serving and toss everything together while they’re still warm. This keeps the potatoes beautifully crisp and the dressing perfectly creamy.

Storage

Store leftovers in an airtight container in the refrigerator for up to 3 days.
While the potatoes will soften slightly after chilling, the flavors continue to develop and are still absolutely delicious.

Ingredients

Crispy Potatoes

2 lbs baby Yukon Gold potatoes
2 tbsp olive oil
1 tsp kosher salt
½ tsp black pepper

French Onion Dip Dressing

1 cup whole milk Greek yogurt
¼ cup sour cream
2 tbsp mayonnaise
1 tbsp fresh lemon juice
1 tsp Worcestershire sauce
½ tsp garlic powder
½ tsp onion powder
½ tsp kosher salt
¼ tsp black pepper

Caramelized Onion Mixture

2 large sweet onions thinly sliced
2 tbsp butter
1 tbsp olive oil
½ tsp salt

Toppings

¼ cup fresh chives finely sliced
2 tbsp fresh dill
½ cup crispy shallots
Fresh cracked black pepper

Crispy Shallots

2 large shallots very thinly sliced into rings
1 cup neutral oil such as avocado or algae for frying
¼ teaspoon kosher salt

Instructions

Roast the Potatoes

Boil potatoes until fork tender, about 15 minutes.
Drain and cool slightly.
Place on a parchment-lined baking sheet and gently smash.
Drizzle with olive oil and season with salt and pepper.
Roast at 425°F for 35-40 minutes, flipping once, until deeply golden and crispy.

Caramelize the Onions

While potatoes cook, melt butter and olive oil in a skillet.
Add onions and salt.
Cook over medium-low heat for 30-35 minutes, stirring occasionally, until deeply golden and jammy.
Cool slightly.

Make the Dressing

Whisk together: Greek yogurt, sour cream, mayonnaise, lemon juice, Worcestershire, garlic powder, onion powder, salt, and pepper.
Fold in half of the caramelized onions.

How To Make Crispy Shallots

Using a sharp knife or mandoline, slice the shallots as thinly and evenly as possible. Pat them completely dry with paper towels to remove excess moisture.
Pour the oil into a small saucepan until it’s about 1 inch deep. Heat over medium heat to 325°F (163°C).
Add the shallots in a single layer (work in batches if needed). Stir gently as they cook to ensure even browning. Fry for 4–6 minutes, or until they turn a light golden brown. Keep a close eye on them—they’ll continue to darken slightly after they’re removed from the oil.
Transfer the shallots to a paper towel-lined plate or wire rack using a slotted spoon. Immediately sprinkle with the kosher salt while they’re still hot.
Let the shallots cool completely. As they cool, they’ll become wonderfully crisp.
