The Complete Guide to Grilling Fish & Seafood

Most people think of BBQ as a meat-lover's game — but grilled fish and seafood can be just as spectacular. In fact, the grill is one of the best ways to cook seafood, adding a smoky char that elevates the natural flavors beautifully. At Smokey's BBQ, we believe the grill belongs to everyone — including seafood lovers. Here's your complete guide.

🔥 The Golden Rules of Grilling Seafood

  • Start with a clean, hot, oiled grill — Seafood sticks easily. Scrub grates clean, heat to high, then oil generously with a paper towel dipped in vegetable oil.
  • Don't move it too soon — Fish will naturally release from the grate when it's ready to flip. If it sticks, it needs more time.
  • Cook hot and fast — Most seafood cooks in minutes. High heat = beautiful char without drying out.
  • Use a fish spatula — Thin, flexible, and wide enough to support delicate fillets without breaking them.
  • Don't overcook — Seafood goes from perfect to rubbery in seconds. When in doubt, pull it early.

🐟 1. Grilled Salmon

Best method: Direct high heat, skin-side down
Cook time: 4–6 minutes per side (depending on thickness)
Internal temp: 125–130°F for medium (slightly translucent in center)

Simple preparation: Brush with olive oil, season with salt, pepper, and lemon zest. Grill skin-side down for 4–5 minutes until skin is crispy, then flip carefully for 1–2 more minutes. Finish with a squeeze of fresh lemon and fresh dill.

Pro tip: Leave the skin on — it acts as a natural barrier against the heat and keeps the fish moist. The skin peels off easily after cooking.

🦐 2. Grilled Shrimp Skewers

Best method: Direct high heat on skewers
Cook time: 2–3 minutes per side
Done when: Pink and opaque, curled into a C shape (not an O — that means overcooked!)

Simple preparation: Toss large shrimp (peeled, deveined, tails on) with olive oil, garlic, smoked paprika, salt, and red pepper flakes. Thread onto skewers. Grill 2–3 minutes per side. Serve with garlic butter for dipping.

Pro tip: Use double skewers (two parallel skewers) to prevent shrimp from spinning when you flip them.

🦞 3. Whole Grilled Fish

Best method: Direct medium-high heat
Cook time: 5–7 minutes per side (for a 1–1.5 lb fish)
Done when: Flesh flakes easily and eyes turn white

Simple preparation: Score the fish 3–4 times on each side (cuts to the bone). Stuff the cavity with lemon slices, garlic, and fresh herbs (thyme, rosemary, or parsley). Rub outside with olive oil, salt, and pepper. Grill on a well-oiled grate. Great varieties: branzino, red snapper, sea bass, or trout.

🧁 4. Grilled Scallops

Best method: Direct high heat, dry scallops only
Cook time: 2 minutes per side
Done when: Golden crust on outside, slightly translucent in center

Simple preparation: Pat scallops completely dry with paper towels (moisture = no sear). Season with salt and pepper. Grill on screaming hot, well-oiled grates for exactly 2 minutes per side. Do not move them. Finish with brown butter and fresh tarragon.

Pro tip: Only use "dry" scallops (not treated with sodium tripolyphosphate). Wet scallops won't sear properly and taste watery.

🦞 5. Grilled Lobster Tails

Best method: Direct medium heat, shell-side down first
Cook time: 5–6 minutes per side
Done when: Meat is opaque and internal temp reaches 140°F

Simple preparation: Split tails in half lengthwise. Brush meat with garlic herb butter (butter + garlic + parsley + lemon). Grill shell-side down for 5 minutes, flip, brush again, and grill 2–3 more minutes. Serve with extra melted butter and lemon wedges. Pure luxury.

🍋 Best Marinades & Sauces for Grilled Seafood

  • Lemon Herb Butter — Melted butter + lemon juice + garlic + parsley. Works on everything.
  • Asian Ginger Glaze — Soy sauce + sesame oil + ginger + honey + rice vinegar. Perfect for salmon and shrimp.
  • Mediterranean Marinade — Olive oil + lemon + oregano + garlic. Great for whole fish.
  • Spicy Chipotle Butter — Butter + chipotle in adobo + lime. Incredible on shrimp and scallops.
