Teriyaki Glazed Tuna Steaks are a fantastic way to enjoy a fresh, meaty fish with a sweet and salty twist. The glaze, made from soy sauce, honey, and a bit of ginger, caramelizes beautifully on the outside of the tuna, giving it a nice, shiny coating and a pop of flavor. The tuna stays tender and juicy on the inside, making every bite something special.
I love making this dish when I want something quick but impressive. The glaze comes together in just a few minutes, and the tuna only needs a short time on the grill or in a pan to get that perfect sear. I find that marinating the steaks for about 20 minutes helps the flavors really sink in, but it’s also great even if you’re in a hurry.
Serving these steaks over a bed of steamed rice or alongside some crunchy veggies makes for a simple, satisfying meal. I like to sprinkle some sesame seeds and chopped green onions on top for a little extra texture and color. It’s a dish that always gets compliments, and I’m pretty sure it’ll become one of your favorites too!
Key Ingredients & Substitutions
Tuna Steaks: Fresh and thick tuna steaks are best for this recipe. Aim for about 1 to 1.5 inches thick so they stay tender inside. If fresh tuna isn’t available, you can try swordfish or salmon, but cooking times may vary.
Soy Sauce: Use low sodium soy sauce to control the saltiness of your glaze. Tamari is a good gluten-free alternative if needed.
Mirin: This sweet rice wine adds depth. If you don’t have mirin, a mix of sake with a little sugar or a splash of rice vinegar works well in a pinch.
Honey or Brown Sugar: Both provide sweetness and help caramelize the glaze. Honey adds a nice floral note, but brown sugar is a great pantry staple substitute.
Fresh Ginger & Garlic: These give the teriyaki its signature zing. Fresh ginger is best, but ground ginger can be used sparingly if needed.
Sesame Oil & Seeds: A little sesame oil adds rich nuttiness to the glaze, and toasted sesame seeds sprinkled on top add a nice crunch and visual appeal.
How Do You Get the Perfect Glaze and Cook Tuna Without Drying It Out?
The secret is twofold: timing and layering the glaze.
- Marinate wisely: Let the tuna sit in half the teriyaki marinade for 15-20 minutes to soak up flavor but not for too long to prevent it from becoming mushy.
- Use high heat: Preheat your grill or pan to medium-high for a quick sear that locks in juices.
- Cook fast: Tuna steaks cook quickly – about 2 minutes per side for medium-rare. Overcooking makes the fish dry and tough.
- Build the glaze: In the last 30 seconds on each side, brush the steaks with the reserved marinade to get a sticky, caramelized coating. Don’t pour it all at once—layer it on gradually for best results.
- Rest briefly: Let the steaks rest 2 minutes before slicing. This helps juices redistribute, keeping your fish moist.

Equipment You’ll Need
- Cast-iron skillet or grill pan – I recommend this because it gets hot quickly and creates nice grill marks. Perfect for searing the tuna.
- Small mixing bowl – great for whisking together the marinade and glaze ingredients.
- Whisk or fork – helps to combine everything smoothly without lumps.
- Plate or tray – for marinating the tuna steaks and letting excess marinade drip off.
- Sharp knife – essential for slicing the tuna into thick strips once cooked.
- Tongs or spatula – makes flipping the tuna easy and gentle.
- Small bowl for dipping sauce (optional) – for serving extra teriyaki or soy sauce on the side.
Flavor Variations & Add-Ins
- Protein swap: Use salmon or swordfish steaks if you prefer a different fish—cooks similarly and pairs well with teriyaki.
- Extra spice: Add a touch of red pepper flakes or sriracha to your glaze for some heat.
- Veggie side: Serve alongside sautéed bok choy, snap peas, or grilled vegetables for more color and crunch.
- Herbal twist: Mix chopped cilantro or green onions into the marinade for fresh, herbal notes.

How Much Time Will You Need?
This recipe takes about 5 minutes to prepare the marinade, 15-20 minutes to marinate the tuna, and roughly 5 minutes to cook. Add a couple of minutes to let the tuna rest before slicing. All together, plan for about 30 minutes from start to finish.
Step-by-Step Instructions:
1. Make the Teriyaki Marinade and Glaze
In a small bowl, whisk soy sauce, honey (or brown sugar), mirin, grated ginger, minced garlic, and sesame oil until the sweetener dissolves. This mixture will flavor your tuna and turn into a lovely glaze.
2. Marinate the Tuna Steaks
Place the tuna steaks in a shallow dish or resealable bag. Pour half of the teriyaki marinade over the tuna, saving the other half for later. Let the tuna soak up those tasty flavors for 15 to 20 minutes at room temperature, or up to 30 minutes in the fridge if you prefer.
3. Heat the Pan or Grill
Warm up a grill or a heavy skillet (cast iron works great) over medium-high heat. Add the vegetable or canola oil if using a pan to prevent sticking and help get a nice sear on your tuna.
4. Cook the Tuna
Take the tuna steaks out of the marinade, letting excess drip off. Place them on the hot grill or pan and cook about 2 minutes on each side for medium-rare—this keeps the inside nicely pink and tender. While cooking, brush on some of the reserved marinade to build a shiny, tasty glaze.
5. Glaze and Caramelize
In the last 30 seconds on each side, brush generously with the remaining marinade to create a beautiful caramelized crust. Keep an eye so the tuna doesn’t overcook and dry out.
6. Rest and Slice
Remove the tuna from heat and let it rest for 2 minutes. This helps the juices settle. Then slice the steaks into thick strips as shown in the photo.
7. Serve and Enjoy!
Arrange the sliced tuna on a bed of steamed broccoli or mixed greens. Sprinkle with sesame seeds and optionally some sliced green onions. Serve with a small bowl of the reserved teriyaki sauce or soy sauce with sesame seeds for dipping. Enjoy your flavorful, tender teriyaki glazed tuna steaks!
Can I Use Frozen Tuna Steaks for This Recipe?
Yes! Just be sure to fully thaw the tuna steaks in the refrigerator overnight before marinating and cooking. Pat them dry with paper towels to remove excess moisture for a better sear.
How Long Can I Marinate the Tuna?
15-20 minutes at room temperature is perfect to allow flavor absorption without affecting the texture. If marinating longer, keep the tuna in the fridge and don’t exceed 30 minutes to avoid a mushy texture.
Can I Cook Tuna Steaks More Well-Done?
You can cook them longer if you prefer, but tuna is best served medium-rare to keep it tender and juicy. Overcooking can lead to dryness and a tougher texture.
How Should I Store Leftover Teriyaki Glazed Tuna?
Store leftovers in an airtight container in the fridge for up to 2 days. To reheat, warm gently in a skillet over low heat or enjoy cold sliced in a salad or sushi bowl.
