When you pan fry the tuna steak, you really don't need to cook them for too long and you really don't want to overcook them.
Tuna is not great overcooked. To get them to cook to medium-rare you need to cook them for about 2 minutes on each sides.
This recipe will work well with any kind of tuna. Just make sure you buy Tuna steaks and not tuna loin or strips.
You can grill this tuna recipe but you’ll need to keep an eye on it to avoid over cooking.
Also when grilling, make sure your grill is cleaned well and oiled to avoid the tuna from sticking.
Technically you can, however, it won't be anywhere as nice as it is pan-fried. Tuna can dry out very easily and cooking it in the oven will dry the tuna out as it takes longer.
Pan-frying on high heat for a short amount of time will make sure it keeps some moisture and doesn't dry out.
Yes, you can use frozen steak, but you need to make sure you fully defrost them before cooking them.
If you wish to you can. It's very popular to marinate these fillets with a teriyaki sauce and this can be a nice option especially in the winter.
I don't marinate the tuna in this recipe as I think the simpler recipe is nicer, especially served with the fresh salad and spicy mango dressing.
