Step‑by‑Step Instructions for 15-Minute Garlic Butter Grilled Fish
Step 1: Prepare the Fish
Start by gently patting the firm white fish fillets dry with paper towels to remove excess moisture. This crucial step ensures the fish sears beautifully on the grill rather than steaming. After drying, arrange the fillets on a plate, ready for seasoning.
Step 2: Season the Fillets
In a small bowl, combine sea salt, cracked black pepper, and paprika. Generously season both sides of the fish fillets with this blend, ensuring even coating for maximum flavor. Let the seasoned fish sit for a few minutes while you prepare the grill, allowing the spices to infuse.
Step 3: Oil the Fish
Lightly brush each seasoned fish fillet with olive oil. This not only helps prevent sticking to the grill but also promotes those enticing grill marks. Make sure the oil coats the surface evenly, preparing each fillet for a glorious sear on the grill.
Step 4: Preheat the Grill
Preheat your grill to medium-high heat, aiming for approximately 400°F (200°C). A hot grill is essential for achieving a perfect sear and locking in the juices of the fish. As the grill heats up, ensure that grates are clean to prevent sticking.
Step 5: Grill the Fish
Carefully place the seasoned fish fillets on the hot grill. Grill for 4-5 minutes on one side until the fillets turn golden brown and easily lift away from the grates. This is a great time to catch the delightful aroma wafting up from your fish.
Step 6: Flip and Butter
Using a spatula, gently flip the fish fillets and grill for another 4-5 minutes until cooked through and the flesh appears opaque. During the last 2 minutes, melt unsalted butter in a small bowl and mix in minced garlic, fresh lemon juice, and chopped parsley. Drizzle this garlic butter over the fish to enhance flavor.
Step 7: Check for Doneness
Once the fish looks opaque throughout and the garlic butter is bubbling, check for doneness. The fish should reach an internal temperature of 145°F (63°C). If it’s perfectly cooked, carefully remove the fillets from the grill, allowing them to rest for a minute before serving.
