Tips

Don't skip rinsing spinach; excess water will dilute the tomato sauce.

FAQ
Can I use frozen fish fillets?
Yes. Thaw completely and pat very dry before using. Frozen fish releases more liquid, so excess moisture is critical to manage.
What if my fish is thicker than standard fillets?
Check doneness at 18 minutes and bake 2-3 minutes longer if needed. Fish is done when it flakes easily with a fork at thickest point.
How long can I keep leftovers?
Refrigerate in an airtight container for up to 3 days. Fish quality declines after day 2. Not recommended for freezing due to texture changes.
