I love the contrast in crispy smashed potato salad: browned edges, soft potato centers, and a cool, tangy dressing with plenty of herbs. Each potato stays in a rough little round, so the bowl has more texture than a finely chopped potato salad.

The potatoes are boiled until tender, pressed flat, and roasted before meeting the creamy dressing. Sour cream or Greek yogurt forms the base, with mayonnaise, Dijon, and lemon juice or vinegar to bring it together. Finely chopped onion adds a little bite.

I first made it for a weekend BBQ with my family, and everyone went back for seconds. This recipe takes a little patience between boiling and serving. Letting steam escape before roasting helps the edges brown, and a short cooling period afterward keeps the dressing from meeting piping-hot potatoes. Fold gently at the end to save those crisp pieces.

Why This Dish Is Great

• Baby potatoes keep their skins, which help hold the tender centers together when they are pressed and roasted.
• The uneven smashed surfaces create small edges that brown nicely in a hot oven.
• The creamy dressing needs only a bowl and whisk, and it can be mixed while the potatoes roast.
• Parsley, dill, or chives offer easy ways to change the herbal flavor without changing the method.
• The four side servings fit comfortably beside a main dish, eggs, or a simple green salad.
• Optional feta or pickles give a finishing touch, but the measured base recipe is complete on its own.

The Best Potatoes For Smashing

Choose similar-sized red or yellow baby potatoes so they soften at about the same pace. Firm potatoes with sound skins are easiest to work with. Scrub them under running water and dry them. Discard spoiled potatoes and avoid green or heavily sprouted ones.

The boiling step should soften the center enough for a fork to slide in easily. A potato that still resists will split awkwardly when pressed. One that falls apart in the water is harder to transfer, so check the largest potato as the smaller ones become tender. Let the cooked potatoes dry before pressing them to about half an inch thick.

Ingredients

• 1 ½ pounds baby potatoes (red or yellow)
• 2 tablespoons olive oil
• Salt and black pepper, to taste
• ½ teaspoon garlic powder (optional)
• ½ cup sour cream or Greek yogurt
• 2 tablespoons mayonnaise
• 1 tablespoon Dijon mustard
• 1 tablespoon lemon juice or vinegar
• ¼ cup chopped fresh herbs (parsley, dill, or chives)
• 2 tablespoons finely chopped red onion or green onion
• Optional: feta cheese, or chopped pickles

Use either sour cream or plain Greek yogurt, and either lemon juice or vinegar. The optional garlic powder seasons the potatoes; it is not a second dressing ingredient. All the measured herbs and onion go into the dressing, with no extra garnish required.

How To Make Crispy Smashed Potato Salad

Plan for about 95 minutes: 15 minutes active preparation, about 10 minutes to bring the water to a boil, up to 20 minutes simmering, 10 minutes drying, 30 minutes roasting, and 10 minutes cooling. The card groups the 60 minutes of heating and cooking together. Oven preheating and dressing preparation overlap the potato cooking. Allow longer if your potatoes, water, or oven need it.

Step 1:

Scrub the 1 ½ pounds baby potatoes under running water. Put them in a large pot, cover with cold water, and add salt to taste. Bring to a boil, allowing about 10 minutes, then simmer for 15–20 minutes until a fork slides easily into the largest potato. Drain in a colander and leave to steam dry for 10 minutes. Meanwhile, preheat the oven to 425°F (220°C).

Step 2:

Line a large rimmed baking sheet with parchment rated for 425°F. Arrange the potatoes in one layer and gently press each to about ½ inch thick with a potato masher. Brush all 2 tablespoons olive oil over the potatoes, then season with salt, pepper, and the optional ½ teaspoon garlic powder. Leave space between the flattened potatoes.

Step 3:

Roast for 25–30 minutes, until the edges are golden and crisp. Turn gently with a spatula halfway through if they release easily; leave them a little longer before turning if they stick. Remove from the oven and cool on the sheet for about 10 minutes, until warm rather than steaming hot.

Step 4:

While the potatoes roast, rinse and dry the fresh herbs and onion before chopping. Whisk the ½ cup sour cream or Greek yogurt, 2 tablespoons mayonnaise, 1 tablespoon Dijon mustard, and 1 tablespoon lemon juice or vinegar in a small bowl. Stir in all ¼ cup chopped herbs and 2 tablespoons chopped onion. Season to taste with salt and pepper, then refrigerate until needed.

Step 5:

Transfer the warm potatoes to a serving bowl and gently fold through all the dressing. Add optional feta cheese or chopped pickles if desired. Serve promptly for the best edges. Refrigerate leftovers in shallow containers within 2 hours, or within 1 hour when the temperature is above 90°F.

Notes

• Do not crowd the roasting sheet. Overlapping potatoes trap moisture; use a second sheet if necessary and allow extra time if batches must roast separately.
• Let the drained potatoes release their steam before brushing with oil. A wet surface makes crisp browning more difficult.
• Press slowly with the masher, keeping the potato in one rough piece. A few cracks are useful, but thin scattered crumbs can darken quickly.
• Use parchment with a suitable temperature rating and keep it inside the pan edges. This recipe uses the oven bake setting, not a broiler.
• Spread the measured oil across all the potatoes instead of letting it collect in one spot. A pastry brush helps reach the uneven surfaces.
• Keep the dressing chilled while the potatoes finish. Warm potatoes are pleasant here, but very hot ones can make the creamy coating loose.
• Dress close to serving. The coating softens the crust over time, so stored salad will have a different texture from the freshly assembled bowl.

Ingredients You Can Add

• Cooked, crumbled bacon adds a smoky topping. Use ready-to-eat bacon or bacon cooked according to its package, and refrigerate it until needed.
• Feta gives a tangy, crumbly finish. Fold it in gently so some small pieces remain distinct.
• Extra chives or green onion can be offered as an optional garnish, separate from the measured herbs already in the dressing.
• Paprika or smoked paprika brings a warm spice note. Sprinkle it lightly over the finished salad.
• Drained pickled jalapeños add heat. Chop them finely so one bite does not get a large piece.
• Chopped pickles or capers give a briny contrast. Drain them well before adding so their liquid does not thin the dressing.

What To Serve

Serve this beside grilled chicken, a sandwich, or scrambled eggs. For a cool lunch pairing, Avocado Chicken Salad has a smooth texture that works alongside the roasted potato edges.

At a cookout, spoon out only what will be eaten promptly and refrigerate the remainder. Greek Pasta Salad is another side option when you want a chilled pasta dish with cucumber and olives.

For a table with several salads, Strawberry Chicken Salad adds fruit and leafy greens. Keep the potatoes separate from those greens so each dish keeps its own texture and dressing.

Recipe Variations And Swaps

• Greek yogurt dressing: use the listed half cup of plain Greek yogurt instead of sour cream. Its tang and thickness vary by brand.
• Lemon or vinegar: either listed tablespoon works. Choose a mild vinegar you enjoy, since its flavor remains noticeable in the finished dressing.
• Herb blend: use parsley, dill, chives, or a combination for the same measured quarter cup. Chop them finely for even distribution.
• Loaded style: add already cooked, chilled chopped egg and cheddar. Keep the base dressing and use these as optional toppings.
• Roasted vegetables: fold in previously roasted, cooled zucchini or peppers. Preparing them from raw adds cooking and cooling beyond the base timing.
• Pesto finish: pesto is an alternative coating with a different flavor. Treat it as a separate version instead of piling another full dressing over this one.
• Crunchy toppings: ready-to-eat roasted chickpeas, sunflower seeds, or pumpkin seeds can go on at serving. Keep them separate during storage.
• Sweet potato version: small sweet potatoes make a sweeter variation, but size and softness change cooking times. Check tenderness carefully and roast until browned, allowing extra time as needed.

How To Store

Refrigerate leftovers promptly in shallow airtight containers at 40°F or below and use within 3 days, or sooner if a component has an earlier limit. Do not leave cooked potatoes out for a long cooling period. Discard portions left out beyond 2 hours, or 1 hour above 90°F; their appearance does not show whether they are safe.

For preparation ahead, store cooked potatoes and dressing separately under refrigeration. Reheat only the undressed potatoes on a baking sheet in a 400°F oven until they reach 165°F, checked with a food thermometer; timing depends on size and amount. Cool briefly before adding cold dressing. Already dressed leftovers are best served cold because reheating can separate the sauce.

FAQ

Why are my potatoes soft rather than crisp?

They may have been wet, crowded, or pressed too thick. Dry after boiling, leave gaps on the sheet, and roast until the edges brown. Dressing also softens the crust naturally.

Can I use larger potatoes?

Baby potatoes are easiest. Larger potatoes can be cut into similar-sized pieces before boiling, but the cooking time and final shape will change. Judge doneness by a tender center.

Should I peel the potatoes?

No peeling is needed for the listed red or yellow baby potatoes. Scrub the skins well before cooking, and choose potatoes with sound skins.

Can I make the dressing ahead?

Yes. Keep it covered in the refrigerator and stir before using. Keep prepared herbs and utensils clean, and count storage from the oldest perishable ingredient.

Can I use plant-based substitutes?

Plain plant-based yogurt and mayonnaise are possible alternatives with different thickness and flavor. Check the labels for your needs; the rest of the ingredients and toppings still matter.

Will a second batch change the total?

Yes. The 95-minute estimate assumes the potatoes roast together. If your oven or sheet cannot fit them with space around each piece, allow another 25–30 minutes for a separate batch, plus any extra handling.
