Get Your Weber Grill Ready

Before any fish touches the grates, proper grill preparation is key:

• Heat It Up: Preheat your Weber grill on high for 10-15 minutes. You’re aiming for a temperature of 400-450°F. A hot grill helps prevent sticking and gives you a great sear.
• Clean Grates: Give your grill grates a good scrub with a grill brush to remove any leftover bits. Clean grates are less likely to stick.
• Lightly Oil: Once clean, lightly brush or spray the grates with a high-smoke-point oil (like canola or grapeseed oil) right before you add the fish. This adds an extra layer of non-stick protection.

Prep Your Fish for Success

A little fish prep goes a long way:

• Room Temp Warm-Up: Take your fish out of the fridge about 10 minutes before grilling. This helps it cook more evenly.
• Pat It Dry: Use paper towels to pat fish fillets completely dry. Excess moisture can steam the fish instead of searing it.
• Oil Up: If your fish has skin, lightly oil the skin side to prevent sticking. Also, brush or rub the flesh side generously with oil.
• Season Away: Now’s the time for your favorite seasonings – salt, pepper, herbs, or a special rub!

The Golden Rule: How Long Do You Cook Fish on a Weber Grill?

A general guideline for perfectly grilled fish is to cook it for about 8-10 minutes per inch of thickness. This is for direct, high-heat grilling with the lid closed.

• 1-inch thick fillet or steak: Grill for 8-10 minutes total.
• 2-inch thick fillet or steak: Grill for 16-20 minutes total.

Keep in mind that fattier fish like salmon and tuna can handle a bit more heat and may cook slightly faster, while more delicate white fish might need a touch less time.

Skin On or Skin Off?

You can grill fish either way. Here are quick tips for both:

• With Skin On: Place skin-side down first. The skin acts as a protective layer, helping the delicate flesh stay together. If you want a quick sear on the flesh, do so for 2-3 minutes before flipping back to skin-side down to finish. The skin will often stick to the grate, allowing you to easily separate the flesh when serving.
• With Skin Off: Be extra gentle when flipping. Grill the flesh side down first for searing, then flip only once to finish cooking. Skinless fish can be more prone to sticking, so make sure your grates are well-oiled.

Average Grill Times for Common Fish (1-inch thick)

Here’s a handy reference:

• Salmon: 8-10 minutes
• Tuna: 8-10 minutes
• Swordfish: 8-10 minutes
• Halibut: 7-9 minutes
• Snapper: 6-8 minutes
• Cod: 6-8 minutes
• Mahi-mahi: 6-8 minutes
• Tilapia: 6-8 minutes

For thicker cuts or whole fish, increase time according to the 8-10 minutes per inch rule.

Top Grilling Secrets for Flawless Fish

• Don’t Be Afraid of Heat: High heat creates a lovely crust, which helps prevent sticking and makes flipping easier. Thinner fillets cook best over higher heat.
• Flip Only Once: Resist the urge to constantly flip. Turning fish multiple times increases the chance of it sticking and breaking apart. Grill the first side longer to build a good crust.
• Let It Release: Don’t force the fish off the grates. If it’s sticking, it’s usually not ready to flip. It will release naturally when a crust has formed.
• Lid Down: Keep the grill lid closed for faster, more even cooking.
• Grill Basket Helper: For smaller or very delicate fillets, a grill basket can be a lifesaver, making flipping super easy.
• Wood Smoke Flavor: Add soaked wood chips (mesquite, hickory, apple) for an extra layer of delicious smoky flavor.
• Rest Your Fish: Just like meat, let your grilled fish rest for 3-5 minutes after removing it from the grill. This allows the juices to redistribute for a more tender result.
• Mind Your Marinades: Fish doesn’t need long marinating times like tougher meats. Limit marinating to a few hours to prevent a mushy texture.

How to Tell When Fish is Perfectly Done

Fish cooks quickly, so stay close and check frequently to avoid overcooking:

• The Flake Test: Use a fork to gently poke the thickest part of the fish. If it’s done, it will easily flake apart. If it looks translucent or raw inside, keep grilling.
• Clear Albumin: As fish cooks, a white protein called albumin may seep out. It will turn opaque and solid white when the fish is cooked through.
• Internal Temperature: For the most accurate reading, use an instant-read thermometer. Fish is safely cooked when it reaches an internal temperature of 145°F.

Remember, overcooked fish turns dry and chewy quickly, so remove it as soon as it passes these tests!

Boost That Flavor!

There are countless ways to make your grilled fish pop with flavor:

• Spice Rubs: Cajun, lemon pepper, garlic pepper, jerk seasoning – endless possibilities!
• Fresh Herbs: Dill, basil, cilantro, parsley, chives.
• Citrus: A squeeze of fresh lemon, lime, or orange juice, or a sprinkle of zest.
• Sauces & Salsas: Teriyaki glaze, chimichurri, mango salsa, and more.
• Marinades: Simple oil and vinegar, soy-ginger, or a wine-based marinade.
