The right marinade adds moisture, allows the fish to take on complex layers of flavor, and prevents overcooking. It’s a simple step that makes a massive difference to your final dish.

Now, let’s explore five marinades that are sure to transform your next grilled fish experience.

Tips for Grilling Perfect Fish Every Time

Marinating is only part of the equation—grilling fish to perfection requires a bit of technique. Here are some tips to ensure flawless results:

1. Use a clean grill: Prevent sticking by thoroughly cleaning your grill grates before cooking.
2. Oil the surface: Lightly oil both your fish and the grill to avoid tearing delicate flesh.
3. Preheat your grill: Ensure the grill is hot before placing your fish on it. This helps create a nice sear and prevents sticking.
4. Don’t overcook: Fish cooks quickly; aim for 3–4 minutes per side, depending on thickness.
5. Use a fish basket: If you’re grilling more delicate fish, a fish basket can help keep it intact and make flipping easier.
