Baked Parmesan Rosemary Potato Crisps

Baked Parmesan Rosemary Potato Crisps are thin, golden potato rounds coated with Parmesan and fresh rosemary, then roasted until crisp around the edges. They’re simple, savory, and a great alternative when you want something somewhere between homemade potato chips and roasted potatoes.

Russet potatoes work especially well because their starchy texture helps the thin slices become crisp in the oven. Cutting them evenly is important—the closer the slices are in thickness, the more consistently they’ll cook.

Why You’ll Love This Recipe

You only need four ingredients: potatoes, olive oil, Parmesan, and rosemary. There’s no deep frying and no complicated preparation.

The texture is especially satisfying. Thinly sliced potatoes become golden and crisp around the edges while maintaining just enough tenderness toward the center.

They’re also incredibly versatile. Serve them as an appetizer, snack, or easy potato side alongside chicken, beef, or sandwiches.

Parmesan adds a salty, cheesy crust as it bakes, while fresh rosemary gives the potatoes a warm, aromatic flavor. A little olive oil helps everything cling to the slices and encourages those golden edges.

Serve these straight from the oven after a short rest. They become a little crispier as they sit for a couple of minutes, especially around the Parmesan-coated edges.

How To Make Baked Parmesan Rosemary Potato Crisps

Step 1: Preheat the oven to 400°F and line a large baking sheet with parchment paper.

Step 2: Scrub the potatoes thoroughly, then slice them into very thin rounds, approximately ⅛ inch thick. Try to keep every slice as consistent as possible so they cook at the same rate.

Step 3: Place the potato slices in a large mixing bowl. Drizzle with the olive oil and toss until every slice has a light coating.

Step 4: Sprinkle the finely grated Parmesan and chopped fresh rosemary over the potatoes.

Step 5: Toss again gently, separating any slices that have stuck together so the Parmesan and rosemary are distributed throughout.

Step 6: Arrange the potato rounds in a single layer on the prepared baking sheet. Leave a little space between the slices rather than overlapping them.

Step 7: Bake for 18–25 minutes, carefully flipping the potato slices about halfway through.

Step 8: Continue baking until the potatoes are golden brown with crisp edges. Keep an eye on thinner pieces toward the end because they may finish first.

Step 9: Remove the baking sheet from the oven and let the potato crisps rest for 2–3 minutes. They’ll become slightly crisper as they cool.

Step 10: Transfer to a serving dish and serve warm.

FAQ

How Thin Should I Slice The Potatoes?

Aim for approximately ⅛ inch thick. Consistent thickness is more important than making every slice extremely thin.

Do I Need To Peel The Potatoes?

No. Scrub the potatoes thoroughly and leave the skins on for extra texture around the edges.

Why Aren’t My Potato Crisps Crispy?

The slices may be too thick or crowded together. Arrange them in one layer with a little space between each piece so moisture can escape.

Can I Use A Mandoline?

Yes. A mandoline is particularly useful here because it produces consistently thin slices, but always use the safety guard and follow the manufacturer’s instructions.

Why Do I Need To Flip Them?

Flipping helps both sides develop more even color and prevents the bottoms from becoming overly browned before the tops are ready.

Can I Use Dried Rosemary?

Yes, although fresh rosemary gives you the best flavor. If using dried rosemary, use less because its flavor is more concentrated.

Reheat them in a hot oven or air fryer rather than the microwave. Dry heat helps restore some of their crisp edges, while microwaving tends to make thin potatoes softer.

What To Serve With Baked Parmesan Rosemary Potato Crisps

Roast chicken: The rosemary and Parmesan work naturally alongside simply seasoned chicken.

Steak: Crispy potato rounds make an easy alternative to traditional roasted or mashed potatoes.

Chicken sandwiches: Serve the crisps instead of regular potato chips or fries for an easy lunch.

Fresh salad: A crisp green salad adds something light and refreshing alongside the savory potatoes.

Green beans: Their fresh flavor works nicely with the Parmesan and rosemary without competing with them.

Creamy dip: A simple sour cream or garlic dip makes these especially good as an appetizer or snack.

Keep the potato slices in a single layer. Even perfectly thin potatoes can turn soft rather than crisp if they overlap and trap moisture during baking.

And watch the baking sheet closely during the final few minutes. Small differences in slice thickness can make some pieces brown faster, so remove any finished crisps early if necessary.
