Okay, so this one was hard to name. Every title I came up with made it sound… well… simplistic. The ingredients and preparation are both simple, but this belies its tastiness. If you think I’m crazy for calling cooked tuna tasty, I feel your pain. At most restaurants it’s either lightly seared (at which point you’re basically eating sashimi), or it’s cooked all the way making it a hard puck that both looks and tastes a bit like cardboard.
Let me assure you that there is a middle ground. One that makes for a delightfully melt-in-your-mouth tender, juicy steak that’s more beef-like than any other kind of fish I can think of. The trick is in marinating it in an ample amount of olive oil, then cooking it through until the middle 1/3 is a nice pink.
As with all simple dishes, the quality of the ingredients is paramount for good results. The tuna should be glistening, firm and not smell the vest bit fishy (dried out, mushy or stinky are not words that should come to mind when you’re picking out any fish). I used asparagus and baby carrots which just came into season. I also took advantage of the carrot leaves for their flavor, but you could just as easily use fennel bulbs and leaves or some other fragrant vegetable that’s in season.

Steps
Place the Tuna steaks on a plate and drizzle a good helping of olive oil on them flipping a few times to make sure they are well coated. Sprinkle with black pepper then rub the cut side of the lemon zest into the steaks (do not salt them yet).
Heat the oven to 400 degrees F and prep the veggies. For the carrots, make one cut at a 45 degree angle, then roll it 1/4 turn away from you then make another cut at the same angle. I'm not sure what this cut is called but it's great because it makes all the pieces of the carrot roughly the same thickness (which you control by how far apart you cut) so they cook evenly. I used a variety of long skinny potatoes and cut them up the same way. Then just toss the carrots, potatoes, and garlic in a good amount of olive oil, salt and pepper. Put this in the oven for about 40 minutes or until the potatoes are almost done.
Add the asparagus and carrot leaves, toss adding more olive oil if it looks like it needs it then put it back in the oven.
- Now it's time to cook the steaks. Heat a heavy bottomed stainless steel or cast iron pan over medium heat until very hot. Remove the lemon zest and discard. Flip the steaks over a few times to make sure they're well coated in oil then sprinkle with kosher salt on both sides. Place the steaks in the hot pan and do not disturb them until they are ready to flip. You'll know they're ready when the bottom third of the steak is brown (the top 2/3's will be red). If the pan was hot enough and they're ready to flip, they should be fairly easy to dislodge and turn with some tongs, but if they are sticking use a spatula. Cook this side until the bottom 1/3 is brown (now the bottom and top thirds should be brown and the middle 1/3 should be pink, not red).
Take the veggies out of the oven after flipping the tuna and plate the veggies. When the tuna is done, put them on top of the veggies right away so they don't overcook. Drizzle 1 tsp of lemon juice and 1 tsp of olive oil on each steak and serve immediately.
