Who made this recipe viral? What's the TikTok origin?

The crispy smashed potato salad was popularized primarily by Poppy Cooks (@poppycooks), a British chef and food content creator whose version has accumulated millions of views. Her recipe combined two existing TikTok trends — crispy smashed potatoes (a long-running technique trend) and the move toward Greek yogurt-based potato salads — into a single dish that went viral in 2024 and has continued to circulate because it actually works as well as it looks on camera. The dish has since been covered by The Kitchn, Sugar and Soul, and multiple British food publications. Multiple other creators have posted variations with slight differences in dressing (some use sour cream, some add capers or pickled shallots, some use lemon juice instead of white wine vinegar), but the core technique — smash, roast hot, cool before dressing — comes from Poppy's approach.

Why does this potato salad stay crispy when a regular potato salad gets soggy?

Regular potato salad is made with boiled potatoes that are soft all the way through. When you coat them in mayo-based dressing, moisture transfers between the dressing and the potato surface until everything equilibrates — in practice, this means the potato absorbs dressing moisture and the dressing thins out over a few hours, producing the mush that makes everyone hate leftover potato salad. Smashed and roasted potatoes are fundamentally different objects: the high-heat roast drives off most of the internal moisture and builds a thick, dehydrated crust on every exposed surface. That crust acts as a moisture barrier. The dressing coats the outside of the crust; it can't penetrate very far because there's no moisture gradient pulling it in. The potatoes stay crispy for 20–30 minutes after dressing, which is the serving window this recipe is designed for. After that, they do begin to soften — this isn't a make-ahead dish in assembled form.

Why do you seed the cucumber? Is it really necessary?

Yes, genuinely necessary. English and Lebanese cucumbers contain a watery gel surrounding each seed cluster — it's the same liquid that runs out when you salt cucumbers. If you dice cucumber with the seeds intact and fold it into a mayo-yogurt dressing, that gel dilutes the dressing within about 10 minutes. The dressing becomes thin, the potatoes pick up less coating, and the whole bowl gets watery. Removing the seeds (takes about 30 seconds with a spoon) eliminates this completely. The cucumber flesh, once seeded, is crunchy and adds fresh flavor without releasing significant moisture. Some variations substitute quick-pickled cucumber (tossed in white wine vinegar and a pinch of salt for 15 minutes before adding) — this also prevents water release while adding extra acidity.

Do I have to use both mayo and Greek yogurt, or can I use just one?

Each ingredient does a different job. Mayo provides fat, body, and that distinctly creamy coating quality. Greek yogurt provides tang, lightness, and a slightly acidic brightness that cuts through the richness of roasted potatoes. Together they make a dressing that's rich but not heavy. Using only mayo produces a dressing that coats beautifully but is quite rich and fatty. Using only Greek yogurt produces a dressing that's tangy and light but thin — it runs off the potatoes rather than coating them, and the finished dish tastes more like potatoes in yogurt sauce than potato salad. The 50/50 combination is the balance Poppy's recipe arrived at for good reason. That said, if you strongly dislike one or the other: pure Greek yogurt works fine and is the healthier option; pure mayo works fine and produces the more traditional-feeling result.

Can I make this ahead?

Partially. You can roast the potatoes up to 4 hours in advance and hold them at room temperature on the baking sheet — don't refrigerate them or they'll turn starchy and dense. Make the dressing and prep all the add-ins (cucumber, herbs) in a separate container. Keep everything separate until 20–30 minutes before serving, then fold together. The finished salad is at its absolute best within the first 20 minutes of assembling. If you refrigerate the assembled salad, the potatoes will soften significantly overnight — it's still edible and tastes fine, but you lose the crispy contrast that makes the dish interesting.

What potatoes work best? Does the variety matter?

Baby new potatoes are the ideal choice for this recipe, and variety within that category matters less than size and age. You want small, waxy potatoes — anything sold as 'baby new potatoes,' 'baby Yukon Gold,' 'creamers,' or 'baby red' potatoes all work well. Waxy varieties (new potatoes, red potatoes, fingerlings) hold their shape when boiled and fan out cleanly when smashed. Starchy varieties (Russets, Idaho potatoes) fall apart when boiled and turn to paste when smashed — they can work for the oven step but produce a different texture that most people don't like for a salad. The 'baby' size matters because you get a high ratio of crispy edge to soft center. A large potato smashed flat produces a bigger slab with less surface-to-thickness ratio. Aim for potatoes no bigger than a golf ball; if your potatoes are larger, halve them before boiling.

Why 400°F / 200°C specifically? Will a lower temperature work?

400°F / 200°C is the lowest temperature that reliably produces truly crispy potato edges in a home oven within 40–45 minutes. At lower temperatures (say 350°F / 175°C), the potatoes heat through before the surface has time to dehydrate and brown — you get soft potatoes with golden-colored but not actually crispy edges. At very high temperatures (425–450°F / 220–230°C), you can shorten the time slightly (30–35 minutes) and get slightly more aggressive browning on the exterior, which some people prefer. The 400°F middle ground is reliable across most ovens without risk of burning. If you have a convection oven, reduce the temperature by 15°F (use 385°F / 195°C) — convection moves hot air and drives off surface moisture faster, so it achieves the same crisping with less heat.

My potatoes came out pale and not crispy. What went wrong?

Three most common causes: (1) The potatoes were still wet when they went in the oven — you need at least 2 minutes of steam-drying after boiling; visible moisture on the surface means they'll steam-roast rather than crisp. (2) The oven wasn't fully preheated — potatoes put into a cold or partially preheated oven start out steaming rather than browning. Always preheat fully. (3) The potatoes were too crowded — if they're touching, they trap steam between them and the edges don't crisp. Give each potato its own space. A fourth possibility: your baking sheet is insulated or very lightweight. Heavy, dark-colored baking sheets transfer heat more aggressively to the bottom surface. A dark, heavy sheet pan at 400°F will produce crispier bases than a thin, shiny, nonstick sheet at the same temperature.

Potato salad has a reputation problem. It’s the dish that shows up at every cookout in a giant Tupperware, gets left in the sun, goes gluey by hour three, and becomes the thing nobody trusts on the leftover shelf. The crispy smashed version — pushed onto everyone’s feed by British chef Poppy O’Toole (@poppycooks) — fixes the one flaw that makes people wary of potato salad: the potatoes are roasted until shatteringly crisp before they ever touch the dressing, so the “salad” part enhances them instead of drowning them.

It went viral because it films beautifully — the smash, the craggy golden edges, the dill-flecked dressing — but it stuck around because it genuinely tastes better than the thing it’s replacing. You get the crunch of a roasted potato and the cool, tangy freshness of a herby dressing in the same bite, and that contrast is the entire point.

Why this beats regular potato salad

A classic potato salad uses potatoes that are soft all the way through, which means the dressing has nothing to push against — moisture migrates back and forth until the whole bowl equalizes into that familiar mush. Roasting changes the physics. The high, dry oven heat builds a dehydrated crust on every smashed surface, and that crust acts as a barrier. The dressing coats the outside; it can’t soak in and turn the potato to paste. You get a comfortable 20-to-30-minute serving window where everything stays crisp — which is exactly why this is a serve-fresh dish, not a make-and-forget one.

The other quiet upgrade is the dressing itself. Swapping half the mayonnaise for Greek yogurt cuts the heaviness that makes a big scoop of traditional potato salad feel like a commitment. It stays creamy enough to cling, but it’s bright and tangy rather than rich and cloying — the right foil for a deeply browned potato.

The three details that decide the outcome

Most failed attempts trace back to moisture. Salt the boiling water like pasta water so the potatoes are seasoned from the inside, then let them steam-dry in the strainer for a full two minutes — a wet potato steams in the oven instead of browning, and that single step is the difference between shatter and sad. Smash decisively to about half an inch so the craggy interior fans open and gives the oven maximum surface to crisp, then leave the pan alone: no flipping. The bottom face welded to the hot sheet is where the best crust forms, and flipping snaps it and lets steam escape.

The last detail is patience at the finish. Let the potatoes rest ten minutes off the heat before they meet the dressing. Fold mayo into steaming-hot potatoes and it splits and turns greasy; fold it into warm ones and it stays glossy and coats cleanly.

Ways to change it up

Loaded. Crumbled bacon, extra chives, and a spoonful of sour cream fold the flavors of a loaded baked potato into salad form.
Herby and green. Blitz the dressing with a big handful of parsley and basil for a green-goddess lean — see our green goddess salad for that dressing template.
Extra tang. Fold in 2 tablespoons of capers or a spoonful of chopped cornichons for a briny, French-leaning bite.
Spiced. A half teaspoon of smoked paprika tossed on the potatoes before roasting adds smoke and color.

What to serve it with

This is a natural partner for anything off the grill — burgers, sausages, grilled chicken thighs, or a plank of salmon. Because it eats lighter than mayo-heavy potato salad, it also holds up next to richer barbecue without feeling redundant. For a fuller vegetarian spread, pair it with a dense bean salad and call it lunch.

Storage

Store the roasted potatoes and the dressing separately and combine within 20 to 30 minutes of serving. The potatoes hold at room temperature on the pan for a few hours; don’t refrigerate them undressed or they turn starchy and dense. Dressed leftovers are still tasty the next day — just accept that the crispy edges will have softened. Re-crisp bare leftover potatoes in a 400°F oven or air fryer for a few minutes and dress a fresh batch rather than reheating the whole salad.
