Ingredients

• 1½ lb total firm white fish fillets (ideally ¾–1-inch thick), such as cod, mahi-mahi, halibut, red snapper, or drum
• 2 tablespoons olive oil, plus a little extra for oiling the grates
• 1 teaspoon kosher salt
• ½ teaspoon black pepper
• 1 teaspoon smoked paprika
• 2 cloves garlic, very finely grated or minced (about 1 teaspoon)
• 1 teaspoon dried oregano (or Italian seasoning blend)
• 1 large lemon (zest of half, plus wedges for serving)
• 2 tablespoons fresh parsley, chopped (optional, for finishing)

Directions

1. Preheat + Clean the Grill: Set your gas grill to medium-high heat (aim for 400-450°F, direct heat setup). If using charcoal, arrange coals for direct heat. Close the lid and let it preheat for 10-15 minutes. Once hot, use a sturdy grill brush to thoroughly clean the grates. This is your first line of defense against sticking!
2. Dry the Fish Really Well: Pat your fish fillets bone-dry with paper towels. This is crucial! Excess moisture creates steam, which prevents a good sear and makes the fish more likely to stick. Dry fish also holds onto the seasoning better.
3. Season: In a small bowl, whisk together the 2 tablespoons olive oil, kosher salt, black pepper, smoked paprika, grated garlic, dried oregano, and lemon zest. Brush or toss the fish fillets evenly with this seasoning blend, ensuring all sides are lightly coated.
4. Oil the Grates (Safely!): Fold a paper towel into a small pad. Dip it in a little extra olive oil. Using long tongs, carefully wipe the hot, clean grill grates with the oiled paper towel. Do this quickly and efficiently to create a non-stick surface.
5. Grill: Carefully place the seasoned fish fillets directly on the oiled, hot grates. Close the grill lid.
   1. When to Flip: Cook for 4-6 minutes, or until the fish easily releases from the grates when gently nudged with a fish spatula. If it resists, give it another minute or two. Once it releases, flip it carefully.
   2. Continue Cooking: Close the lid again and cook for another 3-5 minutes, or until it reaches the target internal temperature.
6. Finish + Rest: Once cooked, immediately transfer the fish off the heat to a clean plate. Squeeze fresh lemon juice over the top. Let it rest for 2-3 minutes before serving. This allows the juices to redistribute, ensuring a moist and tender fillet. Garnish with fresh parsley, if desired.
7. Timing Guidance:
   1. ½-inch thick fillets: Cook approximately 3-4 minutes per side.
   2. 1-inch thick fillets: Cook approximately 4-6 minutes per side.
   3. 1½-inch thick fillets: Cook approximately 6-8 minutes per side.
   4. "When to flip" cues: The fish will go from translucent to opaque, and you'll see grill marks. The most important cue is that it will release easily from the grates when ready to flip. Don't force it!
8. Doneness: How to Know It’s Done
   1. Thermometer Target: The most accurate way! Insert an instant-read thermometer into the thickest part of the fish. It's done when it reaches 140-145°F. Remember, it will continue to cook slightly as it rests.
   2. Visual Cues: The fish should be opaque throughout and flake easily with a fork. It should still look moist, not dry or chalky.
   3. Why Overcooking Happens Fast: Fish is lean and delicate. Its protein structure cooks very quickly, and once it's overcooked, it becomes dry and tough in a flash. Rely on that thermometer!
