Ingredients You'll Need

Every ingredient pulls double duty in this recipe—flavor plus function—so let’s break them down.

Red potatoes are the star thanks to their thin, nutrient-rich skin and moist, waxy flesh that holds together after smashing. Look for golf-ball-size tubers; they cook evenly and give you the ideal crunchy-to-creamy ratio. Avoid extra-large bakers—they need longer boiling and can turn mealy.

Kosher salt in the boiling water seasons the potatoes from the inside out. I keep two bowls on hand: one for salting water, one for finishing the roasted potatoes so the crystals stay visible and provide little pops of salinity.

Extra-virgin olive oil helps the edges brown, but I blend it with butter for its milk-solids flavor. Clarified butter or ghee work if you need dairy-free.

Garlic powder disperses more evenly than fresh minced garlic, which can burn under high heat. Pair it with a whisper of smoked paprika for subtle barbecue undertones.

For the dip, use full-fat sour cream. Reduced-fat versions contain stabilizers that weep when mixed with salt. Fresh chives give a gentle onion bite and a pop of color; snip with kitchen scissors to avoid bruising. A dash of lemon juice brightens the richness, while white pepper adds a mellow heat that won’t leave flecks in the snowy dip.

Optional upgrades: fold grated Parmesan into the potato seasoning for umami, or spike the dip with prepared horseradish for steak-house vibes.

How to Make Crispy Smashed Red Potatoes With A Chive Sour Cream Dip

Pre-heat & prep

Set your oven to 450 °F (232 °C). Position a rack in the lower-middle to encourage browning. Line a rimmed half-sheet pan (13 × 18 in) with parchment for effortless cleanup, or brush lightly with oil if you like extra-crispy undersides.

Boil until fork-tender

Place 2 lb (900 g) red potatoes in a large pot, cover with cold water by 1 in, and season generously with kosher salt—think ocean water. Bring to a boil, then reduce to a lively simmer. Cook 18–22 min until a paring knife slides in with zero resistance. Drain; let steam-dry 2 min so excess moisture evaporates.

Flatten for ridges

Transfer potatoes to the sheet pan. Using the bottom of a heavy drinking glass or a measuring cup, press straight down until each potato is ½–¾ in thick. Pro tip: grease the glass bottom with spray oil to prevent sticking. Rough edges = more crunch later.

Season & fat-coat

Brush or drizzle 3 Tbsp melted butter + 2 Tbsp olive oil across all surfaces. Sprinkle 1 tsp kosher salt, ½ tsp garlic powder, ½ tsp smoked paprika, and ¼ tsp freshly ground black pepper.

Roast until golden

Slide the pan into the oven and roast 25 min. Rotate pan 180°, then continue 10–15 min more until bottoms are caramel-brown and tops look deeply blistered. If you crave even more crunch, flip each potato and broil 1–2 min—watch closely.

Whip the chive sour cream

While potatoes roast, stir together 1 cup sour cream, 2 Tbsp finely chopped fresh chives, 1 tsp lemon juice, ½ tsp kosher salt, and ¼ tsp white pepper. Cover; chill so flavors meld. Stir once more before serving.

Serve & devour

Pile potatoes onto a warm platter, shower with extra chives or flaky salt if desired, and present the dip in a ramekin center-stage. Encourage communal dunking; forks optional.

Expert Tips

Hot pan hack

Preheat the oiled sheet pan inside the oven for 5 min before adding potatoes; the sizzle jump-starts crust formation.

Dry = crisp

After boiling, spread potatoes on a clean tea towel and blot tops; removing surface moisture maximizes crunch.

Freeze flat

Freeze boiled, smashed potatoes on a tray; once solid, bag them. Roast from frozen, adding 5 extra minutes.

Smash uniformity

Aim for equal thickness so every potato finishes at the same time; rotate pan halfway for even browning.

Overnight option

Boil and smash the night before; cover tightly with plastic wrap and refrigerate. Oil & season just before roasting.

Color cue

Edges should be deep amber—any lighter and they’ll taste starchy; any darker and the flavor turns bitter.

Variations to Try

Storage Tips

Refrigerate: Cool leftovers completely, then store in an airtight container up to 4 days. To re-crisp, place potatoes on a wire rack set over a sheet pan in a 400 °F oven for 8–10 min; microwaves turn them rubbery.

Freeze: After boiling and smashing, flash-freeze in a single layer; transfer to freezer bags for up to 2 months. Roast from frozen at 450 °F for 30–35 min, flipping halfway.

Dip storage: Keep the chive sour cream covered in the fridge for 5 days. Stir before serving; drain any accumulated liquid for best texture.

Frequently Asked Questions

Absolutely. Yukon Golds yield a slightly creamier interior; choose the smallest ones so skins remain intact while smashing.

Likely two things: the pan wasn’t preheated enough and the potatoes weren’t oiled on their bottoms. Use parchment or a preheated, lightly oiled metal surface next time.

Yes. Preheat air-fryer to 400 °F. Arrange smashed potatoes in a single layer and cook 10–12 min, shaking halfway. Work in batches for best browning.

Use full-fat sour cream, add salt gradually, and keep refrigerated until serving. Stirring in 1 tsp cream cheese also stabilizes the mixture.

The potatoes can be vegan if you use all oil. For the dip, substitute unsweetened coconut yogurt or cashew cream blended with lemon and chives.

Anything grilled—steaks, pork chops, portobello mushrooms—or roasted proteins like herb-crusted salmon or lemon-garlic chicken thighs. They also elevate casual mains like rotisserie chicken or veggie burgers.
