Ingredients

- 1/2 cup finely grated Parmesan cheese
- 1 tablespoon fresh rosemary, finely chopped
How to Make Crispy Parmesan Rosemary Potato Wafers
1. Prepare the oven and potatoes
Preheat the oven to 400°F. Line a large baking sheet with parchment paper.
Slice the potatoes into very thin rounds, approximately 1/8 inch thick. Keeping the slices as uniform as possible helps them cook evenly and become crisp.
2. Season the potato slices
Place the potato slices in a large bowl and toss them with olive oil until lightly coated.
Add the grated Parmesan cheese and chopped fresh rosemary. Toss gently until the cheese and herbs are distributed over the potato slices.
3. Bake until golden and crispy
Arrange the potato slices in a single layer on the prepared baking sheet. Avoid overlapping them so the edges have room to crisp.
Bake for 18–25 minutes, flipping the slices halfway through. Continue baking until the potato wafers are golden brown and crisp around the edges.
4. Cool briefly and serve
Remove the baking sheet from the oven and let the potato wafers rest for 2–3 minutes. This short resting time allows them to firm up and become even crispier.
Serve warm.
Tips for Extra Crispy Potato Wafers
Pat the potatoes dry: Excess moisture can prevent the potatoes from becoming crisp. After slicing, gently pat them dry with a clean kitchen towel.
Use uniform slices: A mandoline slicer can help create evenly thin potato rounds. If slicing by hand, aim for approximately 1/8-inch thickness.
Don’t overcrowd the pan: Arrange the potatoes in one layer with a little space between them. Overlapping slices can steam instead of crisping.
Watch them toward the end: Thin potato slices can brown quickly. Start checking them around the 18-minute mark, especially if your oven runs hot.
Serve immediately: These Parmesan potato wafers are at their best while warm and freshly baked.
Easy Variations
Yukon Gold Potato Wafers
Replace the russet potatoes with Yukon Gold potatoes for a slightly creamier center and rich potato flavor. Begin checking them a few minutes earlier because they may brown faster.
Mild Herb Potato Wafers
For a milder flavor, reduce the fresh rosemary or substitute a small amount of dried Italian seasoning.
Garlic Parmesan Potato Wafers
Add a small amount of garlic powder to the Parmesan and rosemary mixture for an extra savory flavor.
