Southern 3-ingredient golden lunchroom pennies are one of those humble, old-school side dishes that turn the simplest pantry staples into something irresistible. The name often refers to thin, round potato slices baked until golden like little coins, a style of thrifty cooking that fits right in with lunchroom casseroles, potluck tables, and holiday suppers across the South. With just three ingredients, this version leans on careful slicing and even baking to create crisp edges, buttery flavor, and a tender center.
These potatoes are especially good alongside baked ham, roast turkey, meatloaf, fried chicken, or pork chops, and they fit naturally on a holiday plate with green beans, dressing, or macaroni and cheese. Because they are rich and savory without being complicated, they also pair well with a crisp salad, sliced tomatoes, or a spoonful of chow-chow or pickles to cut through the buttery finish.
Southern 3-Ingredient Golden Lunchroom Pennies
Servings: 6
Ingredients
2 1/2 pounds russet potatoes, peeled and sliced into 1/4-inch rounds
1/2 cup unsalted butter, melted
1 packet dry onion soup mix
Directions
1. Preheat the oven to 375°F. Line a rimmed baking tray or 9x13-inch baking dish with foil and lightly grease it so the potatoes release easily after baking.
2. Place the sliced potatoes in a large bowl. Pour the melted butter over them, sprinkle in the dry onion soup mix, and toss thoroughly so every slice is evenly coated.
3. Spread the potatoes out in a single, slightly overlapping layer on the prepared tray or in the baking dish. Make sure the slices are fairly even so they cook at the same rate.
4. Bake for 35 to 45 minutes, turning the potatoes once about halfway through, until they are tender in the center and deep golden brown around the edges. If you want extra color, let them bake a few minutes longer at the end.
5. Serve hot straight from the tray, spooning over any buttery browned bits from the foil for the best flavor.
Variations & Tips
Add a little cheese: If you want a richer casserole-style finish, sprinkle a light layer of shredded cheddar over the potatoes during the last 10 minutes of baking. It moves the dish beyond the strict 3-ingredient version, but it is a familiar and very good potluck variation.
Choose the right potato: Russets give you the fluffiest centers and the most dramatic contrast between tender middles and crisp edges. Yukon Golds work too and bring a naturally buttery flavor, though the texture will be a bit creamier and less crisp.
Slice evenly: Consistent thickness matters here more than anything else. A mandoline makes quick work of it, but a sharp knife is perfectly fine if you keep the slices close to 1/4 inch so they finish at the same time.
For extra browning: Do not crowd the pan. If the potatoes are piled too deeply, they will steam instead of roast. Using a large tray gives you more of those deeply caramelized edges that make this dish memorable.
Make-ahead tip: You can slice the potatoes a few hours in advance and keep them submerged in cold water in the refrigerator. Dry them very well before tossing with butter and soup mix so they roast properly instead of turning soggy.
