This Crispy Smashed Potato Salad has become my shortcut to bringing people together. I first made it on a sunny weekend when pantry staples and an overflowing box of baby potatoes collided in a moment of inspiration. The result was crunchy on the outside, pillowy on the inside potatoes coated in a bright, tangy dressing that felt both familiar and new. It quickly replaced the heavy, mayo-only versions at our table—everyone loved the contrast between the crisp edges and the creamy herb dressing.

I cook this when I want something that feels special without a lot of fuss. The technique of boiling the potatoes just until fork tender and then smashing them thin before roasting creates a texture that soaks up the herbed yogurt while still delivering delightful shards of crunch. This recipe is ideal for potlucks, weeknight dinners, or as a make-ahead side for brunch. Over the years I've learned small tweaks—like reserving the extra crispy bits for a finishing crunch—that elevate the dish from good to unforgettable.

Ingredients

• Baby potatoes (2 pounds): Mini yellow or baby new potatoes roast beautifully because of their thin skins and even size. Choose firm potatoes with no soft spots—brand doesn’t matter but look for uniform pieces so they cook evenly.
• Olive oil (3 tablespoons, divided): Use a good-quality extra-virgin for flavor when brushing before roasting; reserve a tablespoon for the dressing to round it out.
• Salt & pepper: Coarse kosher salt for the boiling water and fine salt for seasoning after roasting gives the best seasoning control.
• Greek yogurt (3/4 cup): Adds tang and body. Full-fat Greek yogurt yields the creamiest dressing; nonfat works if you prefer a lighter result.
• Kewpie mayonnaise (1/2 cup): Or regular mayonnaise—Kewpie gives a subtle sweetness and umami thanks to rice vinegar and MSG, but classic mayo keeps it familiar.
• Dijon mustard (2 teaspoons): Adds a sharp, savory note that balances the mayo and yogurt.
• Lemon (1/2, juiced): Fresh lemon brightens the dressing more cleanly than vinegar; adjust to taste.
• Garlic (1 clove, minced): Fresh garlic offers a gentle kick; grate it if you want it to disappear into the dressing.
• Fresh parsley (1/4 cup, chopped): Flat-leaf parsley is ideal—bright and slightly peppery.
• Dill pickle (1, finely chopped): Adds crunch and a vinegary pop; use a dill spear or bread-and-butter for milder sweetness.
• Shallot (1, finely chopped): Mild onion flavor that melts into the dressing; substitute red onion if needed (use less).
• Scallions (1–2, for garnish, optional): Thinly sliced for a fresh oniony finish.

Instructions

1. Preheat and prepare: Preheat your oven to 425°F and line a rimmed baking sheet with parchment paper. If your potatoes are very small you may want two sheets so they roast evenly. Make sure your oven reaches full temperature so the potatoes crisp instead of steaming. 2. Boil the potatoes: Place the 2 pounds of baby potatoes in a large pot and cover with cold water by 1–2 inches. Add 1 teaspoon kosher salt and bring to a rolling boil over medium-high heat. Cook 7–8 minutes until a paring knife slips into the largest potato with slight resistance—don’t overcook or they’ll fall apart when smashed. Drain well and let cool just until you can handle them. 3. Smash and oil: Pat the potatoes dry with paper towels to remove surface moisture—this helps them crisp. Transfer to the prepared sheet and, using a potato masher or the bottom of a wide drinking glass, press each potato to about 1/4 inch thick. Brush with 2 tablespoons olive oil and season generously with salt and pepper so every edge has flavor. 4. Roast to crispy perfection: Roast in the preheated oven 45–60 minutes, flipping halfway through so both sides brown. Look for deep golden edges and crackly bits; thinner smashed potatoes may finish sooner—start checking at 35–40 minutes. The steam should have escaped and the surface should feel crisp when tapped. 5. Whisk the dressing: While the potatoes roast, whisk together 3/4 cup Greek yogurt, 1/2 cup mayonnaise, 2 teaspoons Dijon, juice of 1/2 lemon, 1 minced garlic clove, 1 tablespoon olive oil, and 1/4 cup chopped parsley until smooth. Stir in the finely chopped dill pickle and 1 finely chopped shallot. Taste and adjust salt and pepper; refrigerate until ready to use so flavors meld. 6. Toss and finish: When potatoes are done, remove from oven and let rest on the sheet for 10 minutes. Reserve about a tablespoon of the crispiest brown bits for topping. Transfer the rest to a large bowl and gently fold with the herbed yogurt dressing until evenly coated but not mashed further. Garnish with chopped scallions and reserved crispy bits; serve warm or at room temperature.

Storage Tips

Store leftovers in an airtight container in the refrigerator for up to 3 days. If you’ve already tossed the potatoes in dressing, expect softer texture on day two; to revive crunch, spread potatoes on a parchment-lined sheet and reheat in a 375°F oven for 8–12 minutes until edges re-crisp. If you’d like to freeze, freeze the roasted potatoes plain (without dressing) on a tray, then transfer to a freezer bag for up to 3 months; thaw and re-crisp in a hot oven before dressing.

Ingredient Substitutions

If you don’t have Kewpie mayo, use regular mayonnaise or a light mayo for fewer calories. Swap Greek yogurt for sour cream for a richer tang. If you prefer dairy-free, use a dairy-free yogurt and an egg-free mayo—note the texture will be slightly thinner. Replace Dijon with whole-grain mustard for a pop of texture, and swap parsley for dill or chives to shift the herb profile.

Serving Suggestions

This salad pairs beautifully with grilled chicken, smoked salmon, or a simple green salad for a balanced plate. For brunch, serve alongside eggs and roasted tomatoes; for a summer spread, present it with barbecued meats and pickled vegetables. Garnishes like extra chopped parsley, a sprinkle of smoked paprika, or a scattering of crumbled feta can lift the dish for different occasions.

Cultural Background

Smashing and roasting small potatoes is a technique found in many cuisines as a way to maximize surface area and texture—crispy edges are prized in American and European home cooking. This version leans on classic American potato-salad flavors but borrows the lightness of yogurt-based dressings common in Mediterranean cuisine. Adding a dill pickle nods to Central and Eastern European traditions where tangy pickles are often paired with potatoes.

Seasonal Adaptations

In spring, add blanched asparagus tips and chopped radishes. In summer, fold in halved cherry tomatoes and fresh basil for brightness. For autumn and winter, stir in roasted shallots or swap parsley for thyme and finish with a drizzle of browned butter instead of extra oil for a warmed, comforting profile.

Meal Prep Tips

Boil and roast the potatoes a day ahead and refrigerate them un-dressed. Make the dressing in advance and keep chilled; on the day you plan to serve, reheat potatoes briefly to crisp and toss with chilled dressing for the best contrast of warm and cool. Portion into individual containers for grab-and-go lunches; re-crisp in a toaster oven before eating.

Whether you’re feeding a crowd or making dinner for two, this dish brings comfort and brightness in equal measure. Try it once and you’ll find small ways to make it your own—more heat, more herbs, or a tangier pickle—and that’s the joy of cooking: a simple base that invites creativity.
