- Garlic cloves

Step 3: Prepare the Baking Tray
Preheat your oven to 400°F (200°C).
Line a baking tray with baking paper or lightly grease it.
Optional: Create a “bed” of sliced onions or potatoes under the fish to prevent sticking and add flavor.

Step 4: Roast to Perfection

General rule:
- Cook for about 10 minutes per inch of thickness.
You’ll know it’s ready when:

- Flesh flakes easily with a fork

Step 5: Broil for Extra Crispiness (Optional)
For extra crispy skin, switch to broil mode for 2–3 minutes at the end.
Watch closely to prevent burning.
Step 6: Rest and Serve
