HOW TO MAKE SEARED PEPPERCORN TUNA STEAK

Seeking out good-quality tuna is where you need to start. We love ahi tuna, and bluefish is excellent, too.

Coating the steaks with a thin layer of sesame oil and then encrusting in sesame seeds and ground black peppercorns ensure a flavor profile that is incredible.

Watch us show you how to make this incredible dish, along with an amazing strawberry vinaigrette and spinach salad.

HOW TO CHOOSE THE RIGHT TUNA STEAK

As mentioned, this dish is really only as good as the tuna you get from your local fish market.

Sashimi-grade fish is some of the highest quality seafood available. The process in which the fish is caught and immediately processed is why it is safe* to consume raw, as is popular in Japanese cuisine. However, sashimi-grade can be difficult to find in many regions, and most likely not budget-friendly. We recommend yellowfin, bluefin, or albacore when seeing out steaks for our Seared Peppercorn Tuna Steaks.

EXPERT TIP: When seeking out yellowfin or bluefin tuna from a seafood counter, the steaks should have a firm texture and vibrant, red color. Albacore tuna should also have a firm texture but a pale color. All three varieties have similar taste profiles and textures.

GETTING THE PERFECT SEAR

We love a combination of ground black peppercorns and white sesame seeds for the tuna steaks.

Remember, however, that you’ll get some heat from the peppercorns. For medium-heat, go with ¼-cup ground pepper and ¼-cup sesame seeds.

For less heat, only use 2 tbsp of the ground peppercorn. If you prefer no heat at all, use a combination of black and white sesame seeds.

EXPERT TIP: Wondering how to ground peppercorns, easily? Pull out your trusty coffee grinder from the ’90s. They work perfectly! If you don’t have one, or still use it to grind the coffee, then pulverize them in a food processor. Or, place in a baggie, and gently pound until pulverized. One note, the less pulverized they are, the more heat they will produce with each bite. Purchased ground pepper will work in a pinch.

You’ll want to lightly coat the steaks with sesame oil, and then dredge them in the pepper/sesame seed mixture.

Coat them all over. Next, cook them for about 1 to 2 minutes per side. in a medium-high heat skillet with a little oil.

EXPERT TIP: We highly recommend serving the sliced tuna rare to medium-rare. If over-cooked, even in the slightest, the tuna steaks become chewy and the fresh taste is diminished. However, see Note (*) below for more information on consuming rare, or raw food.

WHAT TO SERVE WITH TUNA STEAKS

We absolutely love serving the sliced tuna steaks over a lovely spinach salad.

Toasted pine nuts and crumbled goat cheese are all that is needed to compliment the incredible strawberry vinaigrette.

And the color is stunning.

The steaks can be served warm or room temperature.

Use a sharp knife to cut the steaks into thin strips.

EXPERT TIP: Before dredging the steaks, look to see which direction the grain is on the tuna. You’ll see parallel lines running throughout the fish. This is the grain. You’ll want to slice the steaks against the grain. This allows for more tender, easy to chew bites.

PLATING THE SEARED TUNA WITH THE SALAD

The combination of sweet and bitter in the dressing is the perfect match for the seared peppercorn tuna steaks.

We recommend dressing the salad first in a large bowl and then placing the salad on each serving dish.

Finish the plate off with another drizzle of dressing.

Notes

Albacore, bluefin, and yellowfin are all excellent choices for tuna steak.  Make sure the fillets are firm, and a vibrant bright red in color.  Fresh tuna steaks are always best, but frozen will work, too, if that's all that's available.  Let thaw completely before proceeding with the recipe.  NOTE: Seafood thaws much quicker than beef or poultry. 
Use a spice grinder, or coffee grinder, to grind the peppercorns.  The less fine you grind the peppercorns, the less heat you'll get with each bite.  This recipe, as is, is medium heat.  To reduce heat, go with only 1 or 2 tbsp of the peppercorns, or replace the peppercorns with black sesame seeds.  
Be sure to look at the direction of the grain before you coat with the pepper/sesame seeds.  Once cooked, you'll want to slice the tuna against the grain. 
The vinaigrette can be made up to 2 days in advance.  Store in the fridge and give it a good shake before adding to the salad.
The cooked tuna is best served soon after searing.  However, leftovers can be stored in an air-tight container and kept in the refrigerator for up to 2 days.  We don't recommend freezing the tuna.

  • Super excited to try this recipe. Not really educated on cooking tuna so a few questions. I recent bought two tuna steaks and froze them. They are quite thick. Will they work for this recipe? Should I slice them width-wise to make them thinner, sear, and stay a bit raw on the inside. Or is it a lost cause since I froze them?

    Thanking you in advance.

    • Hi Jane! They should work just fine! Let them thaw and you’ll be in great shape. If they over an inch thick, then give them at least 2 minutes per side, maybe 2 1/2 minutes. And you can always sear them and then cut into one, and if they just seem still too raw, then throw them back in the skillet for another minute, or so! Let us know how it turns out! Best, Kris & Wesley
