Zusatztipps für die Zubereitung

To ensure your fish is as flavorful as possible, make sure to pat the fillets dry before applying the marinade. When sealing the packets, leave a little space for the steam to circulate, but ensure the edges are sealed tight to prevent the juices from leaking onto the baking sheet.

Varianten und Anpassungen

If tilapia isn't available, you can substitute it with other mild white fish such as cod or sole. For those who enjoy a bit of heat, consider adding a pinch of chili flakes to the lemon-garlic mixture before drizzling it over the fish.

Serviervorschläge

This meal is satisfying on its own, but if you have extra calories to spare, it pairs beautifully with a side of fluffy quinoa or brown rice to soak up the zesty lemon-garlic juices from the foil packets.
