Pan Seared Tuna with Rosemary Oil

Seared Tuna With Rosemary Oil

In 2005 Sandy and I took a two week trip to Italy. We started in Venice and worked our way down through Tuscany, Rome and The Amalfi Coast to Sicily. We were married less than two years at the time and didn’t have children yet, so it was the perfect time in our lives for that type of trip. It goes without saying that there were many memorable meals along the way. One such meal was at Osteria da Fiore in Venice.

The best stories about eating while travelling are usually the ones where you just stumbled upon a humble little hidden gem after asking a local in the street. This is not one of those stories. I had planned our dinner at Da Fiore well ahead of time, making a reservation before we even left America. I loved the Da Fiore cookbook and had to go eat there in person. This actually had the potential of being quite the opposite type of story, a lot of build up and hype only to be disappointed. Thankfully, it did not turn out that way. It definitely wasnt cheap, but it was everything I expected, and one of my favorite meals not only of that Italy trip, but of all time.

In the six years since that trip we have had three children. Needless to say another trip to Italy, let alone a romantic dinner for two in Venice, is not in the cards any time soon. So we have to take advantage of the night the two oldest sleep at their grandmother’s and the 1 year old goes down early, by reliving one of the dishes from that legendary dinner, Seared Tuna with Rosemary Oil, at home.

This recipe makes a lot more rosemary oil than you need for the dish, but it keeps for a few months if sealed well and kept in a cool dark place.

  • 1/4 cup chopped fresh rosemary plus 1 or two sprigs for garnish
  • 2 teaspoons crushed hot red pepper
