👩🍳 Step-by-Step Instructions
🔪 Step 1: Prepare the Zucchini
-
Wash and dry the zucchini thoroughly.
-
Slice into ¼-inch thick rounds using a sharp knife or mandoline for even cooking.
🥒 Tip: Try to keep thickness uniform so they cook evenly. Avoid slicing too thin (they’ll burn) or too thick (they won’t crisp).
🧂 Step 2: Season the Rounds
-
Place zucchini rounds in a bowl or lay them on a tray.
-
Drizzle with olive oil and toss gently to coat.
-
Sprinkle with garlic powder, salt, and pepper (plus optional Italian seasoning or paprika if using).
-
Toss again so each round is seasoned evenly.
🧀 Step 3: Add the Parmesan
-
Spread the grated Parmesan on a plate or shallow dish.
-
One by one, press each oiled zucchini round into the cheese to coat one side. The cheese should stick easily thanks to the oil.
-
Arrange rounds cheese-side up on a parchment-lined baking sheet or air fryer tray.
🧀 For crispier results, avoid stacking or overlapping the rounds.
🔥 Step 4A: Bake in the Oven
-
Preheat oven to 425°F (220°C).
-
Bake for 12–15 minutes, or until the cheese is golden brown and the zucchini is tender but crisp on the edges.
-
Optional: Broil for 1–2 minutes at the end to get extra-crispy tops.
🌬 Step 4B: Air Fryer Option
-
Preheat air fryer to 390°F (200°C).
-
Place rounds in the basket or tray in a single layer.
-
Air fry for 8–10 minutes, or until golden and crispy.
-
Shake or flip gently halfway for even browning.
-
⏲️ Air fryer cooking time may vary slightly based on the model and zucchini moisture level. Check around the 7-minute mark.
❄️ Step 5: Cool Slightly and Garnish
-
Let the rounds rest for 3–5 minutes on the tray before serving. This helps the Parmesan set and crisp further.
-
Garnish with chopped parsley or basil, and a sprinkle of sea salt if desired.

🧊 Storage & Reheating

✅ Tips for Perfect Crispy Zucchini Rounds
-
Dry the zucchini well before slicing for better crispiness.
-
Use finely grated Parmesan, not shredded. Shredded cheese can melt into puddles instead of forming a crust.
-
Cheese side up ensures optimal browning.
-
Don’t overbake — they’ll lose their shape and moisture.
