This oven baked 4-ingredient Amish radish and potato roast is the kind of simple spring side dish that feels like it came straight out of a Lancaster County farmhouse kitchen. My grandmother from Lancaster County taught me this recipe, and every time I make it, the pan comes back empty. Tender golden potatoes and blistered pink radishes roast together in plenty of melted butter and black pepper, turning humble vegetables into something cozy and special with almost no effort. It’s perfect for busy weeknights, Easter dinner, or anytime you bring home a bunch of fresh radishes from the market.
Serve this roast straight from the foil-lined baking sheet while it’s still hot and sizzling. It pairs beautifully with roast chicken, baked ham, grilled pork chops, or a simple pan-fried sausage. For a lighter meal, spoon it alongside a green salad with a tangy vinaigrette to balance the richness of the butter. You can also tuck the roasted potatoes and radishes into a warm bowl with a fried egg on top for a hearty brunch, or use leftovers in a breakfast hash the next morning.
Oven Baked 4-Ingredients Amish Radish and Potato Roast
Servings: 4

Ingredients
1 1/2 pounds small gold potatoes, scrubbed and cut into 1-inch pieces
1 pound radishes, trimmed and halved (or quartered if large)
6 tablespoons unsalted butter, melted
1 1/2 teaspoons freshly ground black pepper
1 teaspoon kosher salt (optional but recommended, see variations)
Directions
Preheat your oven to 425°F (220°C). Line a large rimmed baking sheet with aluminum foil for easy cleanup, making sure the foil comes slightly up the sides to catch the butter.
Prepare the vegetables: Scrub the gold potatoes and cut them into roughly 1-inch pieces so they cook evenly. Trim the radishes, removing the greens and root tips, then halve them (or quarter if they are especially large) so they are close in size to the potato pieces.
In a large mixing bowl, combine the potatoes and radishes. Pour the melted butter over the vegetables, then sprinkle on the black pepper and kosher salt if using. Toss well with a large spoon or your hands until every piece looks glossy and coated.
Spread the buttered potatoes and radishes out in a single layer on the foil-lined baking sheet. Try not to crowd them too tightly; a little space between pieces helps them roast and brown instead of steam.
Place the baking sheet on the middle rack of the preheated oven. Roast for 20 minutes, then carefully remove the pan and use a spatula to flip and stir the vegetables so they brown evenly and the butter gets redistributed.
Return the pan to the oven and continue roasting for another 15 to 20 minutes, or until the potatoes are golden at the edges and tender when pierced with a fork, and the radishes are blistered and slightly wrinkled but soft inside.
Taste a potato and a radish, and add a pinch more salt or black pepper right on the hot pan if needed. Give everything a gentle toss so the seasonings and melted butter coat the vegetables again.
Serve the roast directly from the baking sheet or transfer to a warm serving dish. Spoon any buttery pan juices over the top. Enjoy immediately while the potatoes are crisp at the edges and the radishes are still hot and sweet.
Variations & Tips
To keep this true to my grandmother’s Amish-style simplicity, the base recipe uses just potatoes, radishes, butter, and black pepper, with salt as a practical seasoning. If you like, you can add a few homey touches without losing that farmhouse feel. For a milder flavor for picky eaters, use a little less black pepper and cut the radishes into smaller pieces so they blend in more with the potatoes. If someone in your home is sensitive to dairy, you can swap the butter for an equal amount of a neutral-tasting oil (like canola or light olive oil), though you will lose some of that classic buttery flavor. For a slightly herby twist that still feels traditional, sprinkle 1 teaspoon dried parsley or thyme over the vegetables during the last 5 minutes of roasting. To make the dish more filling, you can toss in a few extra potatoes and increase the butter by 1 to 2 tablespoons so everything stays nicely coated. Food safety tips: Always wash and scrub potatoes and radishes well to remove dirt and grit, especially if they are farm- or garden-fresh. Trim off any soft, moldy, or green spots on the potatoes and discard those pieces. Melt butter gently over low heat or in short microwave bursts to avoid splattering. Use oven mitts when handling the hot baking sheet, and keep children a safe distance from the open oven. Refrigerate leftovers within 2 hours in a shallow container, and reheat thoroughly in a hot oven before serving again.
