How To Make It

Tuna is always a grilling favourite, and this tasty version of an Asian classic is easy for you to prepare on your O-Grill. Ideal for dinner party guests, with complex flavors that will enhance everyone’s appetite. The same marinade that is used to coat the tuna also makes an excellent dipping sauce!

Be careful with the seasoning as it is easy to add too much salt to the marinade, and this can overpower the dish. Remember with salt you can always add a bit more later when you serve the dish, but you can’t take it back out! If you find it too salty then a way of reducing this is to use less soy sauce.

When preparing a salty fish dish with strong flavors it’s also good to serve it with a simple accompaniment to refresh the palate and balance the dish. A side salad with plenty of leafy greens goes well with this dish, and you could lightly char some broccoli, asparagus or green beans on your O-Grill alongside the tuna to serve with it.

Instead of tuna you could substitute any oily game fish, like swordfish, barracuda or even mackerel. Try making it with a different fish each time and discover how your O-Grill brings out the different flavors of each fish combined with the sesame and marinade!

Preparing Grilled Sesame Seared Tuna

Step 1 - Prepare the Marinade

Put the tuna and sesame seeds to one side, combine all the remaining ingredients and mix together in a bowl big enough to fit the tuna steaks! Put a couple of tablespoons of the mixture in a cup and keep it for use as a dipping sauce or for pouring over the grilled tuna when you have finished the dish.

Step 2 - Marinade the Tuna

Put the tuna steaks in the bowl of marinade mixture and spoon marinade over the tuna steaks to ensure they are fully marinaded. Cover the bowl with a plate and put it in the refrigerator. Set a timer for 15-20 minutes to give the mixture time for some of it to be absorbed into the tuna.

Step 3 - Coat the Tuna With Sesame Seeds.

Pour the sesame seeds onto a plate. Remove the bowl of marinated steaks from the fridge and one at a time press the steaks into the sesame seeds. Use your fingers to press the sesame seeds against the steaks and work more seeds into the steaks as you go. The honey or sugar in the marinade helps the seeds to stick to the tuna. You can always add more honey to the mix if it isn’t sticking as well as you might like.

Step 4 - Grill the Tuna on Your O-Grill!

You will need to set your O-Grill for a moderately high heat - tuna normally tastes best when it is served rare but has been seared on the outside. Be sure to hold the edges of the steak against the grill for a few seconds with your tongs to sear in the juices. If you grill each side for 3 minutes it will be rare, if you (or a guest) prefer their tuna well done then make it 6 minutes on each side in the O-Grill. If you want your tuna well done, then you may wish to grill it for 3 minutes before adding the sesame seeds, or you might end up burning them!

Step 5 - Serve and enjoy!!

Don’t forget that you put some marinade to the side to save for dipping or as a sauce to put on the tuna - make sure you add that to your dish when you serve it! Your guests will be delighted with the complex flavours of this dish, and you will feel very content with a culinary job well done!
