The Ultimate Guide to BBQ Seafood: How to Cook Tuna Steaks, King Prawns, Cod and Rainbow Trout

Nothing says summer quite like firing up the BBQ and enjoying fresh seafood with family and friends. Fish and shellfish are packed with flavour, cook quickly, and are a lighter alternative to traditional BBQ favourites. Whether you're hosting a garden gathering or simply enjoying a sunny evening meal, these tips will help you cook tuna steaks, king prawns, cod and rainbow trout to perfection every time.

BBQ Tuna Steaks

Tuna steaks are one of the easiest fish to cook on the BBQ thanks to their firm, meaty texture. Brush the steaks lightly with olive oil and season with sea salt, black pepper and a squeeze of lemon. Ensure your BBQ is hot before placing the tuna directly onto the grill. Cook for around 1-2 minutes per side for a beautifully seared exterior while keeping the centre slightly pink and tender. Overcooking tuna can make it dry, so less is definitely more. Serve with a fresh salad, grilled vegetables or a vibrant salsa for a restaurant-quality dish.

BBQ King Prawns

King prawns are a BBQ favourite because they cook incredibly quickly and absorb flavours beautifully. Marinate them for 20-30 minutes in olive oil, garlic, lemon juice and a touch of chilli if you like a little heat. Thread the prawns onto skewers to make them easier to handle on the grill. Cook over medium-high heat for 2-3 minutes on each side until they turn pink and opaque. Be careful not to leave them on for too long as prawns can become rubbery when overcooked. They pair perfectly with fresh crusty bread, salads or grilled Mediterranean vegetables.

BBQ Cod

Cod is a delicate white fish that benefits from careful cooking on the BBQ. To prevent it from sticking or falling apart, place the fillets in a fish basket or on a sheet of foil. Brush with olive oil and season simply with salt, pepper and fresh herbs such as parsley or thyme. Cook over medium heat for approximately 4-5 minutes per side, depending on the thickness of the fillet. The fish is ready when it flakes easily with a fork and remains moist throughout. A squeeze of lemon just before serving enhances its naturally mild flavour.

BBQ Rainbow Trout

Rainbow trout is ideal for BBQ cooking, especially when cooked whole. Fill the cavity with lemon slices, fresh herbs such as dill or parsley, and a little garlic for extra flavour. Brush the skin with olive oil and place directly onto a clean, lightly oiled grill or in a fish basket. Cook for 6-8 minutes per side over medium heat, until the skin is crisp and the flesh is opaque. The result is a beautifully smoky fish that showcases the trout's delicate flavour and tender texture.
