These oven baked 3-ingredient crispy smashed potatoes are the kind of thing you make once and then find yourself planning dinners around them. My neighbor down the hall showed me this trick years ago: par-cook baby potatoes until just tender, then smash them flat so the skins crack open and expose lots of rough edges. A hot oven and a good drizzle of olive oil do the rest, turning those edges into shatteringly crisp, golden-brown bits while the centers stay creamy. Smashed potatoes are a relatively modern American riff on boiled potatoes, but the idea—cooking whole potatoes and then roasting them for texture—echoes rustic European cooking. This is the stripped-down, weeknight version: just potatoes, olive oil, and salt, nothing to distract from that incredible crispy skin.
Serve these hot, straight from the baking sheet, while the edges are still audibly crisp. They’re fantastic alongside roast chicken, grilled steak, or seared salmon, and they hold their own next to a simple green salad or sautéed greens. For a casual spread, pile them onto a board with roasted vegetables and a protein of your choice, and let everyone grab with their fingers. They also make an easy appetizer: set out the tray with a small bowl of sour cream or Greek yogurt and let people dunk. Leftovers (if you have any) reheat well in a hot skillet and are terrific with eggs for breakfast.
Oven Baked 3-Ingredient Crispy Smashed PotatoesServings: 4
Ingredients
2 pounds baby red potatoes, similar size, scrubbed
4 tablespoons extra-virgin olive oil, plus more if needed
1 1/2 teaspoons coarse kosher salt, plus more to finish
Directions
Heat the oven to 450°F (230°C). Line a dark, heavy baking sheet with parchment paper; this helps the potatoes release easily while still allowing the bottoms to brown deeply.
Place the baby red potatoes in a medium pot and cover with cold water by about 1 inch. Add 1/2 teaspoon of the salt to the water. Bring to a boil over medium-high heat, then reduce to a steady simmer and cook until the potatoes are just fork-tender, 12–18 minutes depending on size. You want them soft enough to smash without crumbling, but not falling apart.
Drain the potatoes well and let them sit in the colander for 2–3 minutes so excess steam escapes; drier potatoes crisp better. Transfer them to the parchment-lined baking sheet, spacing them a couple of inches apart.
Use the bottom of a sturdy glass, a small flat measuring cup, or a potato masher to gently press each potato until it’s flattened to about 1/2 inch thick. The goal is to crack and spread the skins so you see lots of jagged edges and exposed interior, but keep each potato in one piece.
Drizzle the flattened potatoes with the olive oil, making sure to hit both the centers and edges. If any spots look dry, add a touch more oil; those rough, uneven surfaces are what will turn extra crispy. Sprinkle evenly with the remaining 1 teaspoon of coarse salt, plus a bit more if you like a saltier bite.
Roast the potatoes on the center rack for 20–25 minutes, until the bottoms are deeply golden and the edges are crisp and browned. For extra crunch, you can carefully flip them during the last 5–10 minutes, but it’s not essential if your baking sheet browns well.
Remove the baking sheet from the oven and let the potatoes rest for 3–5 minutes; this helps the crust set and makes them easier to lift. Taste one and, if needed, finish with a pinch more coarse salt while they’re still hot so it clings to the surface.
Transfer the smashed potatoes to a serving platter or bring the baking sheet right to the table for a rustic presentation. Serve immediately, while the skins are at their crispiest.
Variations & Tips
For such a simple recipe, there are a few easy ways to play with technique while keeping the 3-ingredient spirit. If you like an even crisper crust, let the boiled potatoes cool completely before smashing; the drier surface will brown more aggressively in the oven. You can also increase the oven temperature to 475°F (245°C) for the last 5 minutes of roasting, watching closely to avoid scorching. If you don’t have baby red potatoes, use other small waxy potatoes (like baby Yukon Golds) and keep the size as uniform as possible so they cook evenly. For a slightly different texture, try gently roughing up the surface of each smashed potato with a fork after pressing; those extra ridges catch more olive oil and turn wonderfully crunchy. To stay within the 3-ingredient framework but adjust flavor, vary the salt: a flaky sea salt gives a delicate, briny finish, while a coarse kosher salt reads more assertive and rustic. Finally, if you’re cooking for a crowd, you can boil and smash the potatoes a few hours ahead, hold them on the parchment-lined tray at room temperature, then oil, salt, and roast just before serving so they hit the table blistering hot and irresistibly crisp.
