These oven baked 4-ingredient parmesan rosemary potato wafers are the kind of simple little bite that feels special every time they come out of the oven. They’re crisp around the edges, tender in the center, and full of that cozy smell of rosemary and toasted parmesan that draws everyone into the kitchen. This is a lovely recipe for gatherings, snack boards, or an easy side dish, and it’s especially handy when you want something homemade without a long ingredient list.
Serve these potato wafers warm alongside roasted chicken, grilled steak, soup, or a big green salad for a simple meal. They also fit right in on an appetizer spread with olives, grapes, and a creamy dip like sour cream or herbed yogurt. For family snacking, I like to set them out with a little bowl of marinara or ranch so everyone can help themselves.
Oven Baked 4-Ingredient Parmesan Rosemary Potato Wafers
Servings: 4 to 6
Ingredients
2 large russet potatoes, scrubbed clean and sliced very thin
Directions
1. Preheat your oven to 400°F and line a large baking sheet with parchment paper. Slice the potatoes into very thin rounds, about 1/8 inch thick, so they crisp evenly in the oven.
2. In a large bowl, toss the potato slices with the olive oil, making sure each slice is lightly coated. Sprinkle in the parmesan and chopped rosemary, then toss again so the seasonings cling to the potatoes.
3. Arrange the slices in a single layer on the prepared baking sheet, giving them a little space so the edges can crisp. Bake for 18 to 25 minutes, flipping once halfway through, until the wafers are golden brown and crisp at the edges.
4. Remove the potato wafers from the oven and let them rest for 2 to 3 minutes to crisp up a bit more. Transfer to a serving dish and serve warm.
Variations & Tips
For extra crisp wafers: If your potato slices seem damp, pat them dry with a clean towel before tossing with the oil. The drier the slices are going onto the pan, the better they’ll crisp in the oven.
For picky eaters: You can reduce the rosemary a little for a milder flavor, or swap it for a pinch of dried Italian seasoning. Parmesan still gives these plenty of savory flavor even with fewer herbs.
Make them evenly sized: A mandoline is very helpful here if you have one, since uniform slices bake at the same rate. If cutting by hand, do your best to keep the slices thin and consistent.
Try another potato: Yukon Gold potatoes work nicely too and give a slightly creamier center. They may brown a little faster, so start checking a few minutes early.
Best served fresh: These are at their crispiest right out of the oven, so plan to serve them soon after baking. If needed, you can re-crisp them in a hot oven for a few minutes before putting them on the table.
