The Essential Ingredients for Success
Amberjack Fillets: You will need two thick fillets (approx. 6-8 oz / 170-225g each). Amberjack is firm enough to withstand the heat of the grill without falling through the grates.
Unsalted Butter: 4 tablespoons (56g). This forms the base of our golden sauce, providing a rich mouthfeel that complements the lean protein.
Fresh Garlic: 3 cloves, minced. Sautéing these bits until golden adds a nutty, savory depth that permeates the sauce.
Lemons: 2 large lemons. We use the juice for the sauce and halve the rest to be charred on the grill for a smoky, concentrated citrus punch.
Fresh Flat-Leaf Parsley: 2 tablespoons (roughly 8g), finely chopped. This adds a necessary pop of bright green color and a fresh, herbaceous finish.
Crushed Red Pepper Flakes: 1/2 teaspoon (1g). Just enough to provide a tiny flake of heat that cuts through the richness of the butter.
Seasoning: High-quality flaky sea salt and freshly cracked black pepper are non-negotiable for highlighting the natural sweetness of the fish.
Neutral Oil: 1 tablespoon (15ml) of avocado or grapeseed oil for brushing the grates to ensure those clean, dark grill marks.
Step-by-Step Instructions for the Perfect Char
Preparing the Amberjack
Start by patting your amberjack fillets completely dry with paper towels. Moisture is the enemy of a good sear. If the surface is wet, the fish will steam rather than develop those beautiful caramelized grill marks.
Season both sides generously with cracked black pepper and a light dusting of sea salt. Allow the fish to sit at room temperature for about 10-15 minutes. This ensures even cooking through the thickest part of the fillet.
Mastering the Lemon Garlic Butter Sauce
While the grill preheats, prepare your signature sauce. In a small saucepan over medium-low heat, melt 4 tablespoons (56g) of unsalted butter. Add the minced garlic bits and sauté gently.
Watch for the garlic to turn a pale golden color; do not let it brown too deeply or it will become bitter. Stir in the crushed red pepper flakes and remove from heat. Whisk in the juice of half a lemon and half of your chopped parsley. Keep this warm on the edge of the stove.
Grilling for Visual Impact
Preheat your grill to high heat (approx. 400°F-450°F / 200°C-230°C). Clean the grates thoroughly and brush them with a neutral oil. This is the secret to a professional grilled amberjack recipe.
Place the fillets on the grill at a 45-degree angle to the grates. Press down lightly with a spatula to ensure contact. Grill undisturbed for 4-5 minutes. You will know it is ready to flip when the fish releases easily from the grates. Flip and cook for another 3-4 minutes until the interior is pearlescent white and opaque.
During the last 3 minutes of cooking, place the lemon halves cut-side down on the grill. Cook until they are charred and caramelized. These will be served alongside the fish for extra zest.
The Final Flourish
Transfer the grilled amberjack fillets to a minimalist off-white ceramic plate. Immediately drench the fish in the thick, golden-yellow lemon garlic butter sauce, ensuring it pools in the grooves of the grill marks.
Scatter the remaining fresh flat-leaf parsley and the sautéed garlic bits over the top. Add a final heavy sprinkle of flaky sea salt. The visual of the bright green herbs against the golden sauce and dark marks is what makes this dish truly stand out.
Expert Tips for Success
- The “Hand Test”: If you can’t hold your hand 5 inches above the grill grates for more than 2 seconds, it is hot enough for the fish.
- Skin On or Off? This grilled amberjack recipe works best with skin-off fillets to maximize the surface area for the butter sauce, but skin-on is fine if you prefer the extra crispiness.
- Carry-Over Cooking: Remove the fish when the internal temperature hits 130°F (54°C). The residual heat will bring it to the perfect 145°F (63°C) while keeping it moist.
- Don’t Over-Flip: Only flip the fish once. Every time you move it, you risk breaking the delicate flakes and losing the juices.

Storage, Reheating & Freezing
Storage: Keep leftover grilled amberjack in an airtight container in the refrigerator for up to 2 days. The lemon garlic butter will solidify, so be sure to include any extra sauce in the container to keep the fish moist.
Reheating: Avoid the microwave, which can make the fish rubbery. Instead, place the fillets in a pan with a splash of water or extra butter, cover, and warm over low heat until just heated through.
Freezing: While possible, we do not recommend freezing grilled fish as the texture becomes mushy upon thawing. This grilled amberjack recipe is best enjoyed fresh from the grates.
What to Serve With This Grilled Amberjack Recipe
To keep the meal light and vibrant, serve the amberjack alongside a bed of wild rice or quinoa, which will soak up the excess lemon garlic butter sauce. A crisp green salad or grilled asparagus also makes an excellent accompaniment.
If you are looking for a more heartier meal, consider pairing it with roasted fingerling potatoes seasoned with the same flat-leaf parsley and sea salt used in the main dish. The acidity from the charred lemons provides a perfect palate cleanser between bites of the rich, buttery fish.
