This is one of those recipes that doesn’t really feel like a recipe—more like a memory. My old neighbor, Mrs. K, used to slide a worn metal pan of these rustic potato slices into the oven whenever we had a neighborhood potluck. Just three ingredients, nothing fancy, but the smell of buttery, crisped potato skins and soft, steamy centers takes me straight back to being a kid in her kitchen. If you’re juggling work, family, and everything else, this is the kind of no-fuss side dish you can throw together on a busy weeknight and still feel like you made something cozy and from-scratch.
These rustic potato slices are perfect next to simple roast chicken, grilled pork chops, or even a store-bought rotisserie chicken when you’re short on time. I like to pile them on the table right in the baking pan and let everyone grab their own. They’re great dipped in ketchup, ranch, or sour cream, and they round out a plate with a green salad or steamed veggies. Leftovers reheat well in the oven or air fryer and make an easy side for scrambled eggs the next morning.
Oven-Baked 3-Ingredient Rustic Potato SlicesServings: 4
Ingredients
2 pounds russet potatoes, scrubbed (about 4 medium)
4 tablespoons unsalted butter, melted (plus a little extra for the pan, if needed)
1 teaspoon kosher salt (or to taste)
Directions
Preheat your oven to 400°F (200°C). Place a sturdy metal baking pan (an old, well-used one is perfect) on the middle rack while the oven heats so it gets hot.
Scrub the russet potatoes well under running water, leaving the skins on. Pat them completely dry with a clean towel so they crisp better in the oven.
Slice the potatoes into thick rounds, about 1/2 inch thick. Try to keep the slices roughly the same thickness so they cook evenly.
In a large bowl, drizzle the melted butter over the potato slices and sprinkle with the salt. Toss with your hands or a spatula until every slice is lightly coated and seasoned.
Carefully remove the hot baking pan from the oven. If it looks very dry, rub or brush a small dab of extra butter over the bottom to help prevent sticking.
Arrange the potato slices in a single layer in the hot pan. It’s fine if they’re snug, but avoid stacking them so each slice can brown. Spoon any extra butter from the bowl over the top.
Bake for 20 minutes, then use a spatula or tongs to flip each slice. Return the pan to the oven and bake for another 15 to 20 minutes, or until the skins are browned and crisp and the centers are tender when pierced with a fork.
If you want extra color, move the pan to the top rack for the last 3 to 5 minutes, watching closely so the butter doesn’t burn.
Remove from the oven and let the potatoes sit in the pan for about 5 minutes; the butter will settle into the soft centers and the edges will firm up a bit more.
Serve the potato slices straight from the worn baking pan for that cozy, old-neighbor feel. Taste and sprinkle with a pinch more salt if needed before bringing them to the table.
Variations & Tips
To keep the spirit of the original three-ingredient recipe, I stick to potatoes, butter, and salt—but you can play around once you’ve made them the classic way. Swap in salted butter and reduce the added salt if that’s what you have. If you’re watching dairy, you can try a neutral oil like canola or a light olive oil instead of butter; they won’t have quite the same nostalgic flavor, but they’ll still crisp nicely. For a slightly different texture, cut the potatoes into wedges instead of slices and follow the same method, flipping halfway through. You can also prep the potatoes ahead: scrub, slice, and store them in cold water in the fridge for up to 8 hours, then dry them very well before tossing with butter and baking. If you have leftovers, re-crisp them in a 400°F oven or air fryer for 5 to 8 minutes—they’re great for breakfast alongside eggs or chopped and tossed into a quick skillet hash.
