This was definitely a different way of doing tuna steaks! Not even a hint of dry fish anywhere! It was actually quite simple to make and looked beautiful. I'd almost call this a casserole as you get a whole meal in one dish. Thanks for posting!
Looking for tuna recipes I found this one yesterday and decided to make it because it resembles the fish casserole my Italian aunt used to make with stockfish. As it was very hot (looks like summer, really), I made it in my crock pot as suggested (4 hours on high heat were perfect). Lovely recipe, even DH who is not very fond of tuna (too dry) was happy because it was so juicy. Will make this definitely again. Thanks for sharing, mage of the kitchen :-)
