Ingredients You Need to Make Grilled Tuna Steaks
- Fresh Tuna Steaks: ideally yellowfin tuna (often marketed as ahi tuna). This recipe will also work well for other types of tuna like bluefin, bonito/skipjack, bigeye, or albacore.
- Soy Sauce: Regular or lite soy sauce. Here is my favorite brand!
- Unseasoned Rice Vinegar: Be sure to use unseasoned rice vinegar, not the seasoned version that contains added sugar and salt.
- Honey: Your favorite variety.
- Green Onion: Look for a smooth, firm, bright green onion.
- Toasted Sesame Oil: While plain sesame oil has very little color or flavor, toasted sesame oil has a deep amber color and a nutty, toasty aroma and flavor.
- Fresh Ginger: Look for a plump fresh ginger hand with smooth, shiny skin.
- Garlic: Fresh garlic bulbs should be plump and firm with smooth, silvery skin.
- Olive Oil: Use whatever variety you have on hand - extra virgin olive oil isn't essential here.
- Kosher Salt
- Freshly Ground Black Pepper
How do you know if tuna is fresh enough to serve rare or raw?
It can be intimidating to serve raw or rare tuna at home. How do you know if your fish is fresh enough? It's an important question and one that isn't regulated by the FDA, despite grocery store signage claiming 'sushi grade' or 'sashimi grade' (here is a great article if you want to read about this in depth). It's key to buy from a reputable fishmonger and here are some things to look for:
- Deeply red or pink tuna steaks (not brown) that are moist, shiny, and nearly translucent. (Ideally your fishmonger will cut fresh steaks to order from a whole loin.)
- Tuna steaks should smell of fresh sea-air; avoid those with a fishy odor.
Grilled Tuna Steaks FAQ
Grill tuna steaks over high heat to keep the center rare while achieving beautiful sear marks.
If you prefer your tuna steaks well done, you'll need to grill them for an additional 2 to 3 minutes per side.
Marinating tuna steaks in a mixture that contains acid like vinegar or citrus juice will ultimately cook the fish - as in ceviche. If you choose to marinate your tuna steaks, only do so for 20-30 minutes.
How to Grill Tuna Steaks
Step 1: Whisk together dipping sauce ingredients (soy sauce, rice vinegar, honey, sesame oil, ginger, and garlic).
Step 2: Preheat grill to high. Rinse and dry tuna steaks then rub all sides with oil and season with salt and pepper.
Step 3: Grill tuna steaks until seared on the outside and rare in the middle, about 2 minutes per side. Transfer to cutting board and thinly slice tuna across the grain.
Grilled Tuna Steaks
Ingredients
- 3 tablespoons soy sauce
- 1 tablespoon unseasoned rice vinegar
- 1 teaspoon honey
- 1 tablespoon toasted sesame oil
- 2 teaspoons finely grated fresh ginger
- 1 teaspoon minced fresh garlic
- 2 ahi tuna steaks also called yellowfin tuna
- 2 tablespoon olive oil
- kosher salt
- freshly ground black pepper
- sesame seeds to taste
- thinly sliced green onion to taste
Instructions
- Make dipping sauce. In a medium bowl whisk together soy sauce, rice vinegar, and honey until honey dissolves. Whisk in sesame oil, ginger, and garlic until emulsified. Leave at room temperature or refrigerate if desired. (recipe note #1)
- Preheat a gas grill (or charcoal grill) to high. (recipe note #2)
- Rinse tuna steaks and pat dry with paper towels. Rub all sides of tuna with olive oil and season with salt and pepper. Grill tuna 2 minutes per side, until seared on the outside and rare in the center. (If you prefer a cooked center, cook an additional ~2 minutes per side.) Transfer tuna to cutting board. With a thin, sharp knife, thinly slice tuna across the grain (¼ to ½-inch thick slices). Sprinkle with sesame seeds and sliced green onion. Serve with dipping sauce.
Notes
- If you prefer marinated fish, double the dipping sauce recipe and marinate the rinsed and dried tuna steaks for 20 to 30 minutes in ½ of the sauce before grilling. Serve the remaining sauce alongside for dipping.
- As an optional step to prevent sticking, brush grill grates with a high heat neutral or vegetable oil just before you add steaks to the grill.
- If desired, divide dipping sauce among 4 small bowls for serving.
What a beautiful plate! Ahi tuna is probably my favorite fish, and prepared like this, it's such a hit. Like being at a restaurant, indeed. 🙂 ~Valentina
It's been quite a while since I've had tuna steaks and now I'm thinking it's time! Way to make a restaurant fave even better at home! A nice glass of wine and this and I'm set 😉
Sounds great to me, Dawn! Thank you!
I order rare tuna whenever I get the opportunity when we dine out! One of my favorite entrees! Your steaks are cooked to perfection and your tips are invaluable! Thanks, Marissa.

This is absolutely beautiful, Marissa! One of my favourite things to enjoy when I am out, but I look forward to recreating this at home. Divine!
That's great to hear, Alex! Thank you!
I'm definitely one of those people wary of serving my own raw fish, but I'm always happy to eat it when it's served to me! You've given me confidence with these beautiful seared tuna steaks though! They look SO good Marissa!
aww...thank you, Katherine! I hope you'll give this a try!
This post makes me want to go find a reliable fishmonger! The grocery store version never looks appetizing, but this post is making me crave grilled tuna like crazy right now. And that sesame-honey-soy sauce combination sounds perfect!!
Thanks, David! I hope you're able to track down some great tuna steaks.
I love grilled tuna steaks, but always afraid to make it at home. This is such a simple & easy to make recipe Marissa. Thank you for sharing
My pleasure, Rahul. Enjoy!
I am embarrassed to admit I've never tried fresh tuna - only canned! These tuna steaks look spectacular, and I'm totally digging this soy-sesame-honey marinade - so flavorful!
Wha!? You've got to try fresh, Ben! 🙂
Your tuna steak is perfectly grilled!! I don't have a grill, but I am sure a grill pan would work just fine.
Thank you, Angie! And, yes, a grill pan would work well!
