• Let coals cool completely (24 hours) before disposing
• Never add lighter fluid to already-lit coals (creates dangerous flare-ups)
• Never spray cooking spray directly onto a hot grill (aerosol can ignite)
• Wash hands thoroughly after handling raw fish
• Use separate cutting boards and utensils for raw fish
• Store raw salmon refrigerated until 15-20 minutes before grilling

Step-by-Step Instructions For Grilling Salmon

Step 1: Choose and Prep Your Salmon

Select Quality Fish:

Best Salmon Types for Grilling:

• King (Chinook): Rich, buttery flavor with firm texture – premium choice
• Sockeye: Bold, robust taste with very firm flesh – traditional favorite
• Coho: Mild, delicate flavor with medium-firm texture – versatile option

Preparation:

• Choose Center-Cut Fillets: Select salmon pieces that are 1 to 1.5 inches thick to ensure even cooking and a moist interior without overcooking the surface.
• Place on a Clean Cutting Board: Remove the salmon from its packaging and set it on a cutting board reserved for raw fish to avoid cross-contamination.
• Rinse Quickly Under Cold Water: Briefly rinse the fillets to remove any remaining scales or surface debris without soaking the flesh.
• Pat Completely Dry: Use paper towels to remove all surface moisture. Dry skin and flesh are critical for proper browning and preventing the fish from sticking to the grill.
• Remove Pin Bones: Gently run your fingers along the flesh to locate pin bones, then pull them out with clean tweezers at a slight angle for a smooth fillet.

• Bring to Room Temperature: Let the salmon rest outside the refrigerator for 15–20 minutes before grilling so it cooks evenly from edge to centre.

Step 2: Decide on Skin-On or Skinless

For beginners, the skin-on method is ideal as it prevents sticking, makes flipping easier, and helps retain moisture for a tender, juicy fish. The skin also crisps up when properly oiled, adding texture and flavor.

The skinless method allows seasonings to better penetrate the flesh and creates grill marks. However, skinless fillets are more delicate and need careful handling. For convenience, ask your fishmonger to remove the skin before grilling.

Step 3: Season Your Fish

Basic Dry Rub (for 1-2 pounds salmon):

• 1 teaspoon kosher salt per pound
• 1/2 teaspoon black pepper per pound
• 1/2 teaspoon garlic powder (optional)
• 1 tablespoon fresh herbs like dill or parsley (optional)

Apply generously on both sides, gently pressing into the flesh. Let sit at room temperature for 10-15 minutes.

Alternative Seasoning Options:

1. Lemon Pepper Rub:

• 1 teaspoon each: salt, black pepper, lemon zest
• 1/2 teaspoon garlic powder

2. Cajun Spice:

• 1 teaspoon paprika
• 1/2 teaspoon each: garlic powder, onion powder, thyme, salt, black pepper
• 1/4 teaspoon cayenne

If Using Marinade:

• Place Salmon in a Resealable Bag: Add the salmon to a resealable bag with the marinade, ensuring the fish is evenly coated on all sides.
• Marinate Briefly in the Refrigerator: Refrigerate for 20–45 minutes only. Longer marinating times can break down the flesh and create a mushy texture.
• Pat Dry Before Grilling: Remove the salmon from the marinade and gently pat the surface dry with paper towels to promote proper searing and prevent sticking.

Quick Teriyaki Marinade:

• 1/4 cup soy sauce
• 2 tablespoons mirin
• 2 tablespoons brown sugar
• 1 tablespoon fresh grated ginger
• 2 cloves minced garlic

Step 4: Preheat Your Grill to 400-450°F

For Gas Grills:

• Preheat the Grill on High: Turn all burners to high and close the lid to allow the grill to heat evenly.
• Heat Until Fully Hot: Wait 10–15 minutes until the built-in thermometer reaches 400–450°F, which is ideal for searing salmon.
• Create Heat Zones if Needed: Adjust individual burners to set up direct and indirect heat areas for better control during cooking.

For Charcoal Grills:

• Fill the Chimney Starter: Load the chimney starter to the top with charcoal to generate enough heat for grilling.
• Light and Wait for Ashing: Ignite the charcoal and let it burn for 15–20 minutes, until the coals are mostly covered with a light gray ash.
• Pour Charcoal onto the Lower Grate: Carefully pour the hot coals onto the lower grate, spreading them to create a high-heat zone in the center.
• Create a Cool Zone: Leave one side of the grill with fewer or no coals to form an indirect heat area.
• Position the Cooking Grate: Place the cooking grate back onto the grill and allow it to heat for about 5 minutes.
• Open the Vents Fully: Keep both the bottom and top vents fully open to ensure maximum airflow and consistent high heat.

Temperature Check:

• Use built-in thermometer (target: 400-450°F)
• Or hold hand 5 inches above grates: if you can only keep it there 2-3 seconds, temperature is right
• Slight smoke rising from grates indicates readiness

Step 5: Oil Everything to Prevent Sticking

Oil the Grill Grates:

• Clean Hot Grates Thoroughly: Scrub the hot grill grates with a wire brush to remove any stuck-on residue or debris.
• Prepare an Oil Pad: Fold several paper towels into a thick pad that can hold oil without falling apart.
• Grip with Long-Handled Tongs: Hold the folded paper towels securely with long-handled tongs to keep your hands safely away from heat.
• Soak in Oil: Dip the paper towel pad into vegetable or canola oil until it is well saturated but not dripping.
• Oil the Grates Evenly: Run the oiled pad across all hot grill grates using long, steady strokes, making 3–4 passes for full coverage.
• Expect Smoke and Sizzle: Some smoke and sizzling is normal and indicates the oil is bonding to the grates, creating a natural non-stick surface.

Oil Your Salmon:

• Brush with a Thin, Even Oil Coat: Lightly brush both sides of the salmon with a high-heat oil to reduce sticking and promote even cooking.
• Focus on the Skin Side: If cooking skin-on, apply extra attention to the skin side to help it crisp and release cleanly from the grill.
• Oil All Contact Surfaces: Make sure every part of the fish that will touch the grill is lightly oiled to prevent tearing or sticking during grilling.

Step 6: Place Salmon on the Grill

• Start Skin-Side Down: Place skin-on salmon skin-side down on the grill to achieve the crispiest texture and protect the flesh from direct heat.
• Angle for Grill Marks: Position each fillet at a 45-degree angle to the grill grates to create clean, attractive grill marks.
• Leave Space Between Pieces: Keep at least 1 inch of space between fillets to allow proper heat circulation and even cooking.
• Listen for an Immediate Sizzle: You should hear a strong sizzle as the fish hits the grill. If not, the grill is not hot enough.
• Do Not Move the Fish: Avoid poking, flipping, or adjusting the salmon for 6–8 minutes. The fish will naturally release from the grates once a proper sear has formed.

Step 7: Cook First Side with Lid Closed

Close the lid to create oven-like heat for even cooking.

Timing Guide:

What’s Happening:

• Skin (if on) crisps and protects delicate flesh
• Proteins coagulate, creating firmness
• Natural fats render, self-basting the fish
• Maillard reaction creates caramelized crust

Managing Flare-Ups:

• Small flames from salmon fat are normal and add flavor
• If flames persist beyond 10 seconds, move fish to cooler zone temporarily
• Close lid to starve flames of oxygen
• Never spray water on flames

Step 8: Flip Carefully and Finish Cooking

When to Flip:

• Wait for Natural Release: Allow the salmon to cook until it releases easily from the grill without sticking or tearing.
• Test Gently with a Spatula: Carefully slide a spatula underneath the fish to check if it lifts cleanly.
• Wait If It Resists: If the salmon sticks or resists lifting, give it another 1–2 minutes and test again rather than forcing it.

How to Flip:

• Use a Wide Metal Spatula: Choose a wide, thin metal spatula that can support the entire fillet to prevent breaking.
• Slide Under in One Motion: Glide the spatula fully underneath the salmon in a single, smooth movement without lifting halfway.
• Flip Quickly and Confidently: Turn the fillet in one decisive motion to keep it intact and ensure even cooking.

Second Side Timing:

The second side needs less time. Salmon continues cooking after removal (carryover cooking), so pull slightly before target doneness.

Optional Glaze: If using glazes with sugar or honey, brush on during the last 2-3 minutes only to prevent burning.

Step 9: Check for Doneness

Insert from the side into the thickest part, reaching center without going through.

Target Temperatures:

Visual Indicators (Secondary Confirmation):

• Flesh Turns Opaque: The salmon changes from translucent to opaque as it cooks through.
• Colour Lightens Evenly: The flesh transitions from bright pink to a softer, pale pink when nearing doneness.
• Flakes Gently When Pressed: Light pressure with a fork should cause the fish to just begin flaking without falling apart.
• White Albumin Appears on Surface: A small amount of white protein may rise to the surface during cooking, which is normal and indicates the fish is nearly done.

The Poke Test: Gently press with your finger. Properly cooked salmon feels firm but has some give, like pressing the fleshy part of your palm below your thumb.

Step 10: Remove and Rest

• Transfer with a Wide Spatula: Use a wide spatula to move the salmon carefully to a clean serving platter, supporting the fillet fully as you lift.
• Handle Skin-On Fillets Carefully: If the skin sticks to the grates, gently work the spatula underneath. You can also leave the skin on the grill and lift the cooked flesh away cleanly.
• Let the Salmon Rest: Allow the fish to rest for 3–5 minutes so the proteins relax and the juices redistribute evenly through the flesh.
• Account for Carryover Cooking: The internal temperature will rise by about 5–10 degrees during resting, which is why the salmon is best removed from the grill at 125–130°F for ideal doneness.

Finishing Touches:

• Finish with Fresh Lemon Juice: Squeeze fresh lemon juice over the salmon to brighten flavours and balance the richness.
• Add Herb Butter: Place a small pat of herb butter on top and let it melt naturally over the warm fish.
• Sprinkle Fresh Herbs: Garnish with fresh herbs such as dill, parsley, or cilantro for added aroma and colour.
• Drizzle with a Finishing Sauce: Lightly drizzle a finishing sauce or glaze to enhance flavour without overpowering the salmon.

Quick Glaze Recipes (Apply Last 2-3 Minutes)

Maple Sriracha:

• 3 tablespoons maple syrup
• 2 tablespoons sriracha
• 1 tablespoon soy sauce
• 1 tablespoon lime juice

Honey Garlic:

• 3 tablespoons honey
• 2 tablespoons soy sauce
• 3 cloves garlic, minced
• 1 tablespoon lemon juice

Perfect Side Dish Pairings

Troubleshooting Common Problems

Quick Fixes During Cooking:

• Too Fast: Move to cooler zone or reduce heat
• Too Slow: Increase heat or move to hotter zone
• Skin Won’t Release: Wait longer, use thinner spatula
• Fish Breaking: Stop flipping, continue one side only

Grilling salmon successfully on a BBQ Grill is all about control rather than complexity managing heat zones, allowing a proper sear, and removing the fish at the right temperature. When the grill is fully preheated and the salmon is left undisturbed, it releases cleanly and stays moist. Finish with a brief rest and light toppings, and the grill delivers salmon that’s tender inside, crisp on the outside, and consistently well-cooked.
