Chef Tips for Perfect Results
- Make sure not to overbake the fish to keep it moist and tender.
- For added zest, consider including lemon slices on top of the fish while baking.
- Let the fish marinate for a few minutes before placing it in the oven for maximum flavor.
- Consider serving with a side of sautéed vegetables or a light salad to complement the dish.
- If you’re a garlic lover, feel free to add more minced garlic into the marinade.
Common Mistakes to Avoid
- **Overcooking the fish**: This can lead to a dry result. Always check for flakiness around the 15-minute mark.
