My daughter kept telling me that we needed to check out the tuna steaks they have at Aldi - good price and great quality. Well, this past week we bought some. She suggested a method she and my son-in-law use that sounded great. They use a particular peppercorn as a key ingredient they found at an Asian food store. We didn't have any of those peppercorns so decided to look on line for other interesting ways to cook the tuna. We found a few we thought would be good and made some modifications.
Fresh
tuna steaks, the thicker the better, are best done seared in a screaming hot cast
iron skillet for just a few minutes per side. They are usually served with a simple sauce. This version is different and this is no ordinary sauce. After searing the tuna, it is briefly and gently simmered in a tomato-based aromatic sweet and sour
sauce.
The recipes we liked used these ingredients - dried fruit (golden raisins), tomatoes, lemons, capers, olives and pine nuts and are ingredients found in southern Italian and particularly Sicilian cooking. We've used all of them in other recipes but we improvised a little. We used some dried tangerines instead of raisins. Trader Joe’s sells them as well as Amazon of course and if you haven’t tried them, you’re missing out on a real treat and they went perfectly with this dish.
Briefly, here's how it's done -
Quickly sear the tuna steaks, and set them aside.
Sauté the onions and garlic in some olive oil until the onions
soften slightly.
Add the white wine and let cook down for a couple minutes.
Add
the tomatoes, capers, olives, lemon zest and dried tangerine. Simmer this mixture
for a few minutes to let the juice thicken up a bit and to allow the flavors to
mingle.
The
sauce is now ready. Gently nestle the tuna steaks in the sauce, cover the pan and
simmer for about 2 minutes. You want the tuna to remain nice and
pink inside so you do need to watch
it. When you’re ready to serve, pull the tuna out of the sauce and toss
in the fresh herbs, give it a good stir and simmer for about 1 minute.
Spoon some of the sauce on the plate with the tuna on top or spoon over each steak.
Note - You don't usually see fresh tuna simmered in a sauce because it’s difficult to keep the tuna
nice and pink. But this recipe works and it’s just simply
delicious. We served this with a side of pasta dressed with garlic, herbs and olive oil. Polenta would work very well with this too as well as arborio rice made into a risotto with fish sauce.
This sauce can be made ahead and
reheated. I think it might taste even better if you made it the day before. It’s a nice option to
have.
Here is the step by step -
Servings: 4
Ingredients -
1/4 cup
extra-virgin olive oil
1 tablespoon canola oil
1 to 1 1/4
pounds of tuna steaks, at least 1-inch thick (about 4 -6 small)
Salt
and freshly ground black pepper to taste
1 cup sliced
onions (about 1 large onion)
1/4 cup chopped
dried tangerines (use golden raisins if you can’t get the dried tangerines)
Zest
from 1 lemon and the juice from the lemon to squeeze over the tuna
4 garlic cloves,
minced
2 tablespoons
capers, rinsed and drained
10 Castrovetrano olives, sliced
1 lb fresh
tomatoes chopped or a 15-ounce can diced or crushed tomatoes
1/2 cup water, use as needed to thin sauce if necessary
1/4 cup dry
white wine
3 tablespoons
fresh basil leaves, chopped
2 teaspoons
fresh oregano, chopped
1/3 cup pine
nuts - toasted
½ lb pasta, we
used linguine (alternately, you could use basmati rice or polenta)
- Heat a heavy,
medium skillet (prefer cast iron) over moderately high heat. Add the canola oil and
let it warm.
- Season the tuna
with salt and pepper; sear for 2 minutes per side, or until both sides are
golden and the center is still pink.
- Remove the tuna
and set aside. Do not clean the pan.
- Using the same
pan, sauté the onion with the garlic and lemon zest in the olive oil, stirring frequently until
just tender, about 2-3 minutes. Deglaze with the white wine and let cook down.
- Add the capers, olives, dried tangerine slices and tomatoes. Continue cooking, for another 2 -3 minutes.
- Let simmer for a
couple more minutes until the sauce thickens and has some body.
- Return the tuna
to the pan, nestling the tuna down in the tomato sauce. Squeeze some lemon juice over the tuna from the lemon you zested. Cover with a tight-fitting
lid. Continue to cook over low heat until the tuna reaches the desired
doneness, 2 to 3 minutes for medium.
- Remove the tuna
to a serving plate.
- Add the fresh
herbs to the sauce and season to taste with salt and pepper; stir well.
- Set the tuna on top of the sauce on a plate or spoon it over the top of the tuna; garnish with the pine nuts.
NOTE: It’s important that the tuna steaks are at least 1 inch thick…the
thicker the better, as the tuna will be less likely to overcook. The sauce can
be prepared early in the day, or even the day before then the tuna can be done
just before serving, simmered briefly in the sauce.
