Grilled Garlic Butter Salmon

Grilled garlic butter salmon starts with a seasoned salmon fillet cooked skin side down, then finished with melted butter, fresh garlic, lemon juice, and green onions. The grill provides the main cooking heat while the separate butter mixture adds moisture and flavor at serving. Keeping the finishing sauce separate also avoids dripping large amounts of butter onto the grill.

This recipe uses one large fillet, about two pounds, rather than individual portions. Its thickness matters more than its length when checking doneness. Jump to the recipe card for the original measured ingredients and cooking method.

Ingredients for Grilled Garlic Butter Salmon

• 1 large salmon fillet, about 2 lb
• 2 tbsp olive oil
• 3 tbsp unsalted butter, melted
• 3 cloves garlic, minced
• 1 tbsp fresh lemon juice
• 1 tsp smoked paprika
• 1 tsp garlic powder
• ½ tsp black pepper
• ½ tsp salt
• 3 green onions, chopped

Choose a fillet suited to the method

The directions cook the fish skin side down, so choose a skin-on fillet for that approach. A broad, fairly even piece is easier to manage than a very thin tail attached to a thick center. If the fish has pin bones, remove them before seasoning. Thaw frozen salmon in the refrigerator and pat the surface dry before adding the oil.

Seasoning and finishing butter

Olive oil helps the smoked paprika, garlic powder, salt, and black pepper adhere to the fish. The finishing sauce uses melted unsalted butter, fresh garlic, and lemon juice. Garlic powder seasons the fish itself, while minced fresh garlic flavors the butter. They play different roles and both remain in the original recipe.

Chopped green onions go on after grilling, adding a fresh contrast to the warm sauce. Prepare them before the fish reaches the grill. Keep the butter mixture and any serving utensils away from raw salmon so the sauce can be spooned directly over the cooked fish without cross-contamination.

How to Make Grilled Garlic Butter Salmon

1. Prepare and season the salmon

Pat the salmon dry with paper towels. Brush lightly with the olive oil and season evenly with smoked paprika, garlic powder, salt, and black pepper. Place it on a tray that can be carried to the grill. Have a separate clean serving platter ready so the cooked salmon never goes back onto the tray that held raw fish.

2. Heat and prepare the grill

Preheat the grill to medium-high heat, about 400°F. Clean and lightly oil the grates using your grill’s recommended method. A clean cooking surface helps the skin release without tearing. Prepare a wide spatula, or two tools that can support the large fillet together, before you begin cooking.

3. Grill skin side down

Set the salmon on the grill skin side down and close the lid. Begin checking within the recipe’s approximate 8–12 minute window, allowing more time when a thick fillet needs it. Avoid repeatedly lifting the fish to inspect the bottom. Leaving the fillet supported by its skin makes it easier to keep the flesh intact.

4. Check the thickest part

Use a food thermometer in the thickest part of the salmon. Finfish should reach 145°F (63°C), according to FDA safe cooking guidance. The flesh should also look opaque and flake readily. Grill temperature, thickness, and starting temperature can change the timing, so the clock alone cannot confirm that the center is done.

5. Add garlic butter and green onions

Combine the melted butter, minced garlic, and lemon juice in a clean bowl. Transfer the cooked salmon carefully to the clean serving platter and spoon the warm butter over the surface. Sprinkle with chopped green onions and let the fish rest briefly before portioning. Spoon any sauce collected on the platter over the individual servings.

Tips for Handling a Large Fillet

Support the salmon from underneath when moving it. Tongs can pinch through the flesh once the fish starts to flake, while a wide spatula distributes the weight. If the fillet is too large for one tool, use a second spatula at the other end. Portioning on the serving platter is often easier than trying to divide the fish on the grill.

If the surface colors faster than the center cooks, move the fish to a less intense area of the grill and continue with the lid closed. Check doneness again before serving. For a skillet fish dinner with a different glaze, try sweet chili lime garlic butter cod.

Serving, Storage, and Questions

Serve with rice, grilled vegetables, or a green salad. Keep the sides ready before the salmon comes off the grill so the butter can be spooned over warm portions immediately. For a creamier salmon dish on another evening, see creamy garlic salmon bites with rice.

Refrigerate leftovers promptly in a shallow covered container. Reheat portions gently to 165°F throughout, recognizing that salmon will be firmer after reheating. Keep only the portions you need over heat to avoid repeatedly warming the whole fillet.
