Watched my aunt make these at Sunday dinner and finally got her to share the secret after 20 years.

These oven baked 3-ingredient brown butter potato chunks are exactly what my aunt set on the table every Sunday for nearly 20 years before finally walking me through her method. They look simple—just potatoes, butter, and salt—but the secret is taking the butter all the way to nutty brown and roasting the potatoes hot enough that they caramelize and turn deeply golden. The result is a bowl of glistening, crisp-edged potato chunks with soft, fluffy centers, the kind of unfussy side dish that quietly steals the show at family dinners.

Serve these potatoes piled into a warm ceramic bowl so the brown butter gathers at the bottom and stays glossy. They’re perfect alongside roast chicken, pork chops, grilled steaks, or seared salmon. For a lighter meal, pair them with a big green salad dressed with a sharp vinaigrette to cut through the richness. They also sit nicely on a brunch table next to scrambled eggs or an omelet, and any leftovers reheat well in a hot skillet for breakfast potatoes the next day.

Servings: 4

2 pounds russet or Yukon Gold potatoes, scrubbed and dried

Preheat your oven to 425°F (220°C). Place a large, heavy sheet pan on the middle rack while the oven heats so it gets hot; this helps the potatoes brown and crisp.

Cut the scrubbed, dried potatoes into chunky, even pieces about 1 to 1 1/2 inches wide. Leave the skins on for better texture and caramelization. Pat the cut potatoes dry with a clean towel to remove surface moisture.

Make the brown butter: Add the unsalted butter to a small light-colored saucepan or skillet over medium heat. Let it melt, then continue to cook, swirling the pan often, until the butter foams, then the foam subsides and the milk solids at the bottom turn a deep golden brown and smell nutty, 4 to 6 minutes. Watch closely so it does not burn.

As soon as the butter is browned, remove it from the heat to stop the cooking. Stir in the kosher salt while the butter is still hot so the salt disperses evenly.

Place the potato chunks in a large mixing bowl. Pour the warm brown butter and salt mixture over the potatoes, scraping in all the browned bits from the pan. Toss thoroughly until every surface of the potatoes is coated and glistening.

Carefully remove the hot sheet pan from the oven. Quickly spread the potatoes out in a single layer on the pan, cut sides down as much as possible, leaving a little space between pieces so they roast instead of steam.

Roast the potatoes in the preheated oven for 25 minutes without stirring, allowing the bottoms to develop a deep golden crust. After 25 minutes, use a spatula to gently turn the potatoes, exposing new sides to the pan.

Continue roasting for another 15 to 20 minutes, or until the potatoes are well caramelized on multiple sides, crisp at the edges, and tender all the way through when pierced with a knife.

Transfer the hot potatoes to a warm ceramic serving bowl, scraping any browned butter and crispy bits from the pan over the top. Taste and add a pinch more salt if needed. Serve immediately while they are still sizzling and glossy.

For a slightly different character while keeping the spirit of the three-ingredient recipe, you can change the potato variety or the fat. Yukon Golds give a naturally buttery flavor and creamy center, while russets crisp more dramatically on the edges. If you need to avoid dairy, you can use a plant-based butter that is labeled suitable for high-heat cooking and brown it gently; many will still develop a toasty aroma, though the flavor will be a bit different. If you’d like a hint of herb flavor without technically adding another ingredient to the pan, serve the finished potatoes over a bed of fresh herbs in the bowl so they perfume the dish without affecting the core method. For extra crispness, you can briefly parboil the potatoes in salted water for 5 minutes, drain very well, and let them steam off before tossing with the brown butter and roasting; this encourages an even creamier interior and more textured surface. Food safety notes: Always handle hot brown butter carefully—it can splatter and burn skin if agitated too vigorously. Use a light-colored pan when browning butter so you can see the color change and avoid burning; butter that turns black or smells acrid should be discarded and remade. Keep raw potatoes out of standing water at room temperature for extended periods to prevent quality loss, and refrigerate leftovers within 2 hours of cooking. Reheat leftovers thoroughly in a hot oven or skillet until steaming throughout before serving.
