Teriyaki Glazed Tuna Steaks are a simple but delicious meal featuring tender, juicy tuna steaks coated in a sweet and tangy teriyaki sauce. The glaze caramelizes nicely on the outside, giving each bite a perfect mix of sticky and savory flavors that really make the fish shine.
I love how quick this dish comes together—I usually marinate the tuna for just a bit before searing it to keep it moist and full of flavor. The best part for me is getting that beautiful glaze to stick and slightly char on the pan; it adds a nice texture that’s so satisfying. Sometimes I even add a sprinkle of sesame seeds or green onions on top for a little extra crunch and color.
Serving these tuna steaks over steamed rice or alongside a fresh salad turns the meal into something special but still easy enough for a weeknight dinner. I find that a simple side of sautéed veggies or some pickled ginger really complements the teriyaki flavor. Whenever I make this, friends always ask for seconds, which is a great sign it’s a keeper in my recipe box!
Key Ingredients & Substitutions
Fresh Tuna Steaks: Look for thick, firm steaks for the best texture. If you can’t find tuna, swordfish or salmon work well as substitutes, though flavor will differ slightly.
Soy Sauce: This is essential for the teriyaki flavor. Use low-sodium if you want less salt, or tamari for a gluten-free option.
Mirin & Sake: Mirin adds sweetness and a mild tang. If you don’t have mirin, a mix of rice vinegar and sugar works. Sake is optional but adds depth; you can skip it if needed.
Brown Sugar or Honey: Both sweeten and help with caramelization. I prefer honey for a subtle floral note.
Vegetable or Sesame Oil: Sesame oil adds nutty flavor but burns easily. Use vegetable oil for high-heat searing, then add a little toasted sesame oil at the end for taste.
How Do You Get a Perfect Teriyaki Glaze and Keep Tuna Tender?
Balancing a shiny glaze with perfectly seared, tender tuna is key. Here’s how I do it:
- Marinate the tuna briefly (20–30 min) so flavors soak in without making the fish mushy.
- Heat the pan until hot before adding oil; this gives quick, even searing.
- Sear tuna steaks quickly on each side (1.5–2 min) to keep the center pink.
- Brush reserved marinade during cooking to build up a sticky glaze without burning.
- Rest the tuna a minute after cooking; it helps retain juices.
- Slice against the grain for a tender bite and evenly coated pieces.
Equipment You’ll Need
- Heavy skillet or grill pan – I recommend a cast-iron skillet because it heats evenly and creates a nice sear for the tuna.
- Whisk and small bowl – these are perfect for mixing the marinade quickly and smoothly.
- Tongs or spatula – easy to flip the tuna steaks without breaking them apart.
- Measuring spoons and cups – help keep the marinade proportions just right.
- Plate or tray – for marinating the fish in the fridge safely.
Flavor Variations & Add-Ins
- Try adding a splash of citrus juice (like orange or lime) to the marinade for a fresh twist.
- Use salmon or swordfish steaks instead of tuna for different flavors and textures.
- Garnish with sliced avocado or a sprinkle of crushed red pepper flakes for more color and heat.
- Top with toasted sesame seeds or chopped cilantro right before serving for extra flavor and visual appeal.
Teriyaki Glazed Tuna Steaks
Ingredients You’ll Need:
- 2 fresh tuna steaks (about 6 oz each, 1 to 1.5 inches thick)
- ¼ cup soy sauce
- 2 tbsp mirin (sweet rice wine)
- 1 tbsp sake (optional)
- 1 tbsp brown sugar or honey
- 1 tsp freshly grated ginger

How Much Time Will You Need?
This recipe takes about 10 minutes to prepare plus 20-30 minutes for marinating. Cooking the tuna steaks and plating will take an additional 5-10 minutes, making the total time around 35-45 minutes.
Step-by-Step Instructions:
1. Make the Teriyaki Marinade
In a small bowl, whisk together soy sauce, mirin, sake (if using), brown sugar or honey, grated ginger, and minced garlic. This will be your flavorful teriyaki marinade.
2. Marinate the Tuna Steaks
Place the fresh tuna steaks in a shallow dish or resealable plastic bag. Pour half of the marinade over the steaks, making sure they’re coated well. Cover or seal and refrigerate for 20–30 minutes. Keep the remaining marinade for cooking.
3. Sear the Tuna
Heat the vegetable or sesame oil in a heavy skillet or grill pan over medium-high heat until it’s hot but not smoking. Remove the tuna from the marinade, letting the excess drip off (discard the used marinade). Sear the tuna steaks for about 1.5 to 2 minutes per side if you like them rare inside. For more cooked, sear longer, brushing the reserved marinade occasionally to build a shiny, caramelized glaze.
4. Rest and Slice
Take the tuna steaks off the heat and let them rest for a minute. Then slice the steaks thickly against the grain. This will keep the meat tender and make beautiful presentation slices.
5. Garnish and Serve
Place the sliced tuna on plates and drizzle with any pan glaze. Sprinkle toasted sesame seeds and chopped green onions on top. Serve immediately with shredded purple cabbage or your favorite sides like steamed rice or pickled vegetables. Enjoy your delicious teriyaki glazed tuna steaks!
Can I Use Frozen Tuna Steaks for This Recipe?
Yes, you can use frozen tuna steaks, but be sure to thaw them completely in the refrigerator overnight before marinating. Pat them dry with paper towels to remove excess moisture for better searing.
Can I Make the Teriyaki Glaze in Advance?
Absolutely! You can prepare the marinade ahead of time and store it in the fridge for up to 3 days. Just whisk it again before using to recombine any settled ingredients.
How Should I Store Leftover Teriyaki Tuna?
Store any leftovers in an airtight container in the fridge for up to 2 days. Reheat gently in a pan over low heat or enjoy cold sliced over a salad or rice bowl.
What If I Don’t Have Mirin or Sake?
No problem! Substitute mirin with a mix of rice vinegar and a pinch of sugar, and omit sake or replace it with a splash of dry white wine or water. This will keep the flavor balanced.
