Where to buy your ahi tuna steaks for grilling

I love the ahi tuna steaks available at Sprouts Farmers Market. Sprouts offers 100% sustainably sourced seafood. They source from fisheries that are committed to preserving and protecting the health of our marine and freshwater ecosystems and the well-being of fishery-dependent communities.

When you shop sustainably sourced seafood, you’re supporting fisheries who reduce the pressure on our ecosystems caused by overfishing and habitat-damaging fishing methods.

What’s the difference: ahi vs albacore tuna?

Albacore tuna is the most frequently found tuna in stores, lighter in color, and milder in flavor. It’s sometimes labeled as “white tuna” as well. Ahi tuna, also known as yellowfin tuna, is typically higher in quality and better suited for searing, grilling, or served raw for sushi or poke bowls.

Should you worry about ahi tuna mercury levels

Ahi tuna is considered a high mercury fish and should be eaten sparingly and no more than one time per week.

Best tuna steak seasoning

The best seasoning for a simple ahi tuna recipe is some soy sauce, garlic and sesame seeds in my opinion. But if you want a strictly dry seasoning for your grilled ahi tuna, I recommend some salt, pepper, garlic powder, and ginger. It’s perfection!

Now let’s get into how to grill ahi tuna steaks.

First, combine the soy sauce, green onions, lemon juice, garlic, and sesame oil in a bowl and whisk them all together well.

Then, add your ahi tuna steaks to a large plastic bag. Pour the marinade you just whisked together into the bag and seal it tight, pressing out all of the air as you close it. 

Lay the bag flat and make sure the marinade is coating all of the tuna steaks. Let them marinate for about 30 minutes.

Meanwhile, spread the sesame seeds on a plate in a flat even layer. Remove the tuna steaks from the bag and press each one into the sesame seeds making sure all of the sides are coated.
