This 5-ingredient oven depression era potato planks recipe leans on the kind of thrift and simplicity home cooks relied on in the 1930s, when potatoes often carried a meal. Here, raw peeled potato planks are sliced, seasoned, and simply dumped onto a baking sheet with four basic pantry add-ins, then roasted until the edges are crisp and the centers are tender. It’s the kind of unfussy, practical dish you can pull together on a weeknight, yet it’s so satisfying and flavorful that friends will assume there’s a secret technique involved.
Serve these oven potato planks hot, straight from the baking sheet, with a simple green salad or steamed vegetables to keep the meal light and balanced. They’re also excellent alongside roast chicken, grilled sausages, or a pan-fried pork chop. For a more casual spread, pair them with burgers or veggie patties and a tangy dipping sauce like ketchup, mustard, or a quick yogurt-garlic sauce. Leftovers reheat well in a hot oven and make a great base for breakfast, topped with a fried egg and whatever cooked vegetables you have on hand.
5-Ingredient Oven Depression Era Potato PlanksServings: 4
Ingredients
2 pounds russet or yellow potatoes, peeled and cut into 1/4-inch thick planks
3 tablespoons neutral oil (such as vegetable or canola oil)
1 1/4 teaspoons fine salt
1/2 teaspoon freshly ground black pepper
1/2 teaspoon garlic powder
Directions
Preheat your oven to 425°F (220°C). Place a dark, non-stick baking sheet on the middle rack while the oven heats so it gets hot; this helps the potato planks crisp on the bottom.
Peel the potatoes and slice them lengthwise into planks about 1/4-inch thick. Try to keep the pieces fairly uniform so they cook at the same rate.
In a large bowl, combine the neutral oil, salt, black pepper, and garlic powder. Stir or whisk briefly to distribute the seasonings evenly through the oil.
Add the raw peeled potato planks to the bowl. Toss thoroughly with your hands or a large spoon until every surface of the potatoes is lightly coated with the seasoned oil.
Carefully remove the hot baking sheet from the oven. Dump the seasoned raw potato planks directly onto the baking sheet, then quickly spread them into a single, even layer. The planks should be lying flat with a little space between them; crowding will make them steam instead of crisp.
Place the baking sheet back in the oven and roast for 20 minutes without stirring, allowing the undersides to develop color and the potatoes to soften.
After 20 minutes, use a thin spatula to flip the potato planks. Return the sheet to the oven and continue roasting for another 10 to 15 minutes, or until the planks are golden brown on the edges and tender in the center when pierced with a fork.
Taste a plank and add a light sprinkle of extra salt if needed while they’re still hot. Serve the potato planks directly from the baking sheet or transfer to a warm platter, making sure to scrape up any crisp bits stuck to the pan.
Variations & Tips
For a more herb-forward version that still respects the simplicity of the original, swap the garlic powder for 1/2 teaspoon of dried thyme or dried rosemary, or use a mix of dried herbs you already have on hand. If you’d like a smoked note, replace part of the black pepper with 1/4 teaspoon of smoked paprika. To echo older Midwestern tables, you can finish the hot potato planks with a small pat of butter dotted over the top right after baking; it will melt and add richness without changing the core 5-ingredient structure if you treat it as an optional flourish. For crispier results, avoid stacking or overlapping the planks; if your baking sheet is small, cook in two batches rather than crowding. Food safety tips: Always wash and dry your potatoes before peeling to remove surface dirt, and use a sharp knife and stable cutting board when slicing into planks to prevent slipping. Do not soak the potatoes for long periods at room temperature; if you need to hold them in water, keep the bowl in the refrigerator and dry the planks well before tossing with oil so they roast instead of steaming. Leftovers should be cooled quickly, stored in a covered container in the refrigerator, and eaten within 3 to 4 days; reheat on a hot baking sheet to restore some crispness.
