Ingredients (serves 3–4)
4 medium potatoes, very thinly sliced (use a mandoline if you have one)
½ cup grated Parmesan cheese
2 tbsp olive oil
1 tsp salt
½ tsp black pepper
1 tsp garlic powder
1 tbsp chopped fresh basil or oregano (for finishing)
Optional: 2 tbsp panko breadcrumbs (for extra crunch) or a pinch of smoked paprika / red pepper flakes for heat
Time
Prep: 10–20 minutes (plus optional 15–30 minute soak)
Cook: 10–18 minutes per batch (depending on slice thickness)
Total: 25–50 minutes
Yield
About 3–4 servings (adjust quantities and cook in batches for larger crowds)
Prep & Pro tips (read before you start)
Soak for extra crispiness: After slicing, soak potato slices in cold water for 15–30 minutes to remove surface starch. This improves crisping. Pat completely dry.
Even slices = even cooking: Use a mandoline or very sharp knife; aim for ~1/16–1/8 inch (1.5–3 mm).
Don’t overcrowd: Air fry in a single layer—cook multiple batches if needed. Overlapping -> soggy edges.
Parmesan adhesion: Toss slices with oil first, then the cheese mixture. Press gently so the cheese sticks. A light egg wash helps adhesion but isn’t necessary.
Step-by-Step — Air Fryer Method
1. Prep the potatoes
Wash (and optionally peel) the potatoes. Slice very thinly.
(Optional) Soak slices in cold water 15–30 minutes, then drain and pat very dry on paper towels.
2. Make the Parmesan coating
In a bowl combine: grated Parmesan, salt, black pepper, garlic powder, and panko (if using). Mix well.
3. Oil + coat
In a large bowl toss the dry potato slices with the olive oil until each slice is lightly coated.
Add the Parmesan mixture and toss gently so the cheese/breadcrumb mix adheres. For best adhesion, press the coated side lightly between your palms or press each disc onto the bowl rim.
4. Preheat air fryer
Preheat to 380°F (190°C) for 3–5 minutes. (If you prefer hotter/shorter cook time, 400°F / 200°C works too—watch closely.)
5. Air fry in a single layer
Arrange potato discs in a single layer in the basket (coated side up if you pressed them). Leave space around each disc.
Cook at 380°F (190°C) for 10–14 minutes for thin slices (about 1.5 mm). Flip halfway (around 6–7 minutes) for even browning.
For slightly thicker slices (~3 mm): cook 14–18 minutes, flipping once.
Check at the lower end of time—air fryer models vary. You want golden edges and crisp centers.
6. Finish & serve
Remove to a wire rack so steam doesn’t soften them. Sprinkle with chopped fresh basil or oregano and a touch more Parmesan if desired. Serve warm.
Serving suggestions
Dip with garlic aioli, spicy mayo, ranch, or marinara.
Serve alongside grilled chicken, burgers, or a fresh green salad.
Stack them as a crunchy base for small bruschetta or smoked salmon bites.
Variations & swaps
Sweet potato version: Use thin sweet potato slices—reduce cook time slightly and watch for quicker browning.
Herb twist: Swap basil for rosemary, thyme, or a sprinkle of lemon zest for brightness.
Vegan: Use olive oil + nutritional yeast or a vegan Parmesan alternative.
Extra crispy: Double-coat (oil → cheese/breadcrumb → oil → cheese) or use panko only on half the batch for texture contrast.
Storage & reheating
Store: Cool completely; keep in an airtight container in the fridge up to 2–3 days.
Reheat: For best crispness, reheat in the air fryer at 350°F (175°C) for 3–5 minutes, or in a 375°F (190°C) oven for 7–10 minutes.
