10 Mouthwatering Grilled Tuna Steak Recipes You Need to Try This Week

Okay, real talk. Tuna steaks are one of those things that sound fancy but are honestly so easy to pull off at home. I started making them on weeknights and never looked back.

You get that gorgeous sear, all that flavor, and dinner is done in under 20 minutes. Right?

Whether you like it bold and spicy or light and herby, there is a grilled tuna steak recipe on this list with your name on it. Let’s get into it.

1. Lemon Garlic Grilled Tuna Steak

Ingredients

• 2 tuna steaks (about 6 oz each, 1 inch thick)
• 3 tablespoons olive oil
• 4 cloves garlic, minced
• 2 tablespoons fresh lemon juice
• 1 teaspoon lemon zest
• 1 teaspoon salt
• 1/2 teaspoon black pepper
• 2 tablespoons fresh parsley, chopped

Step 1: Make the marinade

Grab a small bowl and mix together the olive oil, minced garlic, lemon juice, lemon zest, salt, and pepper. Smells amazing already, right?

Give it a good stir until everything comes together. This marinade is simple but it does a lot of heavy lifting. The lemon brightens up the tuna in the best way possible.

Step 2: Marinate the tuna

Pat your tuna steaks dry with a paper towel first. This step matters more than people think. Dry fish sears way better than wet fish.

Place the steaks in a shallow dish and pour the marinade over them. Flip once to coat both sides. Let them sit for 15 to 20 minutes at room temperature. No need to refrigerate for a short marinade like this.

Step 3: Heat the grill

Preheat your grill or grill pan over medium high heat. Brush the grates with a little extra oil so nothing sticks. You want it hot enough that you hear a loud sizzle the second the fish hits the surface.

Not sure if it’s hot enough? Hover your hand about 3 inches above. If you have to pull back in 2 seconds, you’re golden.

Step 4: Grill and serve

Lay the steaks on the grill and do not touch them for 3 to 4 minutes. I burned one once by poking at it too early. Trust the process.

Flip once and cook another 2 to 3 minutes for medium rare. Sprinkle fresh parsley on top right before serving. Squeeze a little extra lemon over everything. You’re doing great.

2. Teriyaki Grilled Tuna

Ingredients

• 2 tuna steaks (6 oz each)
• 3 tablespoons soy sauce
• 2 tablespoons mirin
• 1 tablespoon honey
• 1 teaspoon sesame oil
• 1 teaspoon fresh ginger, grated
• 2 cloves garlic, minced
• 1 tablespoon sesame seeds (mixed black and white)
• 1 teaspoon vegetable oil for grilling

Step 1: Mix the teriyaki sauce

In a small bowl combine soy sauce, mirin, honey, sesame oil, grated ginger, and garlic. Whisk it together until the honey dissolves completely. This is my favorite part. It already smells like something amazing is about to happen.

If you only have regular oil instead of sesame oil, that works too, though the sesame flavor really makes this one sing.

Step 2: Marinate the tuna

Pat the steaks dry and place them in a zip lock bag or shallow dish. Pour about two thirds of the sauce over the steaks. Reserve the rest for later. Marinate for 20 to 30 minutes in the fridge.

Longer than 30 minutes and the soy can start to cure the fish a little. It’s not bad, just different. Keep it under 30 for best texture.

Step 3: Sear on high heat

Heat your grill pan or skillet over high heat with a drizzle of vegetable oil. When it’s shimmering and almost smoking, carefully place the tuna in.

You want a hard sear here. Press gently with a spatula to ensure full contact. Cook 2 to 3 minutes per side. The outside should be caramelized and a little sticky. Yep, that’s it right there.

Step 4: Finish and plate

Remove from heat and drizzle the reserved teriyaki sauce over the top. Scatter sesame seeds generously over each steak.

Slice against the grain if you want that beautiful presentation you see in the photos. Serve with steamed rice or on a banana leaf for extra style points. Honestly, it’s better than most restaurant versions.

3. Cajun Blackened Tuna Steak

Ingredients

• 2 tuna steaks (6 oz each)
• 1 tablespoon smoked paprika
• 1 teaspoon cayenne pepper
• 1 teaspoon garlic powder
• 1 teaspoon onion powder
• 1 teaspoon dried thyme
• 1 teaspoon dried oregano
• 1/2 teaspoon salt
• 1/2 teaspoon black pepper
• 2 tablespoons butter
• 1 tablespoon vegetable oil

Step 1: Make the blackening spice blend

In a small bowl mix together paprika, cayenne, garlic powder, onion powder, thyme, oregano, salt, and black pepper. Give it a stir and take a little sniff. Bold, smoky, a tiny bit intimidating. Perfect.

You can dial back the cayenne if you want less heat. I make this for my family and I always do a half teaspoon for the kids. Still tastes incredible.

Step 2: Season the tuna

Pat your tuna steaks completely dry. Press the spice blend firmly onto both sides of each steak. Really press it in with your palm. You want a solid, even coat all over.

The crust is everything in this recipe. Looks messy right now, trust the process. That dark crust is where all the flavor lives.

Step 3: Heat a cast iron skillet

This recipe really wants a cast iron skillet. Preheat it over high heat for about 3 minutes until it’s seriously hot. Add butter and oil together. The oil keeps the butter from burning.

Open a window. Blackening gets smoky and that’s totally normal. Not a kitchen fire, just good cooking happening.

Step 4: Blacken the tuna

Carefully place the seasoned steaks into the hot skillet. Do not move them. Cook 2 to 3 minutes per side. The spices will turn very dark, almost black. That is the point.

You’ll see the edges turn gray as the cook travels inward. When it’s about a quarter inch from the top, flip it. Serve immediately with mashed potatoes on the side. So good.

4. Honey Soy Grilled Tuna

Ingredients

• 2 tuna steaks (6 oz each)
• 3 tablespoons soy sauce
• 2 tablespoons honey
• 1 tablespoon rice vinegar
• 1 tablespoon sesame oil
• 2 cloves garlic, minced
• 1/2 teaspoon red pepper flakes
• 1 tablespoon sesame seeds
• 2 lime slices for serving

Step 1: Whisk the honey soy glaze

Combine soy sauce, honey, rice vinegar, sesame oil, garlic, and red pepper flakes in a bowl. Whisk until the honey is fully incorporated and the sauce is glossy. Quick check here. Taste it. You want that balance of salty, sweet, and just a little heat.

Too sweet? Add a few more drops of rice vinegar. Too salty? A tiny extra squeeze of honey fixes it right up.

Step 2: Marinate and prep

Pat the tuna dry and place in a shallow dish. Pour half the glaze over both sides. Let it sit for 15 minutes while you heat up the grill.

Keep the other half of the glaze. You will brush it on during cooking and it is honestly the secret to that sticky, gorgeous finish you see in the photos.

Step 3: Grill with the glaze

Grill the tuna over medium high heat for 3 minutes. Brush the top with reserved glaze before you flip. Flip and brush the other side too. Cook another 2 to 3 minutes.

This is where it gets good. The glaze caramelizes right on the fish. You can literally see it bubbling and thickening. Smells incredible.

Step 4: Plate it up

Remove from grill and immediately scatter sesame seeds over the top. Add lime slices on the side. Serve over rice or with an Asian slaw for a full meal.

The lime squeeze right before eating brightens the whole dish. Do not skip that part.

5. Mediterranean Herb Tuna

Ingredients

• 2 tuna steaks (6 oz each)
• 3 tablespoons olive oil
• 3 cloves garlic, minced
• 1 tablespoon fresh oregano, chopped
• 1 tablespoon fresh thyme, chopped
• 1 tablespoon fresh parsley, chopped
• 1 teaspoon capers, roughly chopped
• 1 teaspoon red chili flakes
• 1 lemon, juiced
• Salt and black pepper to taste

Step 1: Prepare the herb oil

In a small bowl combine olive oil, garlic, oregano, thyme, parsley, capers, and chili flakes. Mix it all together. This herb oil smells like summer in Italy and I am not exaggerating even a little.

Learned this combination from my mom who always kept fresh herbs on the windowsill. She would put this on everything. Honestly a great habit.

Step 2: Season and coat the tuna

Pat the tuna steaks dry and season with salt and pepper on both sides. Spoon about half the herb oil over both sides and press gently so the herbs cling to the surface.

Let it rest for 10 minutes. You do not need a long marinade here. The herbs are fragrant enough that even a short rest makes a big difference.

Step 3: Grill until beautiful

Heat your grill pan over medium high heat. Place the tuna on the grill and cook 3 to 4 minutes per side. You want clear grill marks and a slightly opaque edge with a pink center.

Wondering when it is done? Press the center gently. It should feel firm on the outside but give just a little in the middle. That is medium and that is perfect for tuna.

Step 4: Spoon and serve

Remove from heat and immediately spoon the remaining herb oil over the top. The residual heat will warm the herbs and release all those amazing aromas.

Serve alongside a simple green salad with cherry tomatoes. The freshness of the salad against the herby tuna is such a clean, beautiful combo.

6. Garlic Butter Seared Tuna

Ingredients

• 2 tuna steaks (6 oz each)
• 3 tablespoons unsalted butter
• 4 cloves garlic, thinly sliced
• 1 tablespoon olive oil
• 1 tablespoon fresh lemon juice
• 1 tablespoon fresh parsley, chopped
• 1 teaspoon capers
• 1/2 teaspoon red chili flakes
• Salt and pepper to taste

Step 1: Season the steaks

Pat the tuna steaks completely dry. Season generously with salt and pepper on both sides. Do not be shy here. Tuna is a meaty fish and it can handle bold seasoning.

Set the steaks aside at room temperature for about 10 minutes. Cold fish hitting a hot pan causes uneven cooking. This little rest makes a real difference.

Step 2: Start the garlic butter

Heat olive oil in a skillet over medium high heat. Add sliced garlic and let it sizzle for about 30 seconds until golden and fragrant. Then add the butter and let it melt and foam.

Pause here. Watch that garlic. Golden is perfect. Brown is okay. Dark brown means start over. I have been there. It is a fast window.

Step 3: Sear the tuna

Add the tuna steaks to the pan. They should sizzle loudly. That sound is good. Really good. Tilt the pan slightly and use a spoon to continuously baste the steaks with the garlic butter as they cook.

Cook 2 to 3 minutes per side. The basting is the whole magic of this recipe. You are basically frying the top of the fish while the bottom sears. So much flavor happening right now.

Step 4: Finish with lemon and serve

Remove the tuna from the pan. Add lemon juice, capers, parsley, and chili flakes directly to the butter in the pan. Swirl it together for 30 seconds over low heat.

Pour the entire pan sauce over the plated tuna. Serve immediately. This one honestly tastes like something you would order at a nice restaurant. So easy.

7. Spicy Sriracha Lime Tuna

Ingredients

• 2 tuna steaks (6 oz each)
• 2 tablespoons sriracha sauce
• 2 tablespoons fresh lime juice
• 1 tablespoon soy sauce
• 1 tablespoon honey
• 1 teaspoon sesame oil
• 1 teaspoon garlic powder
• 1 tablespoon sesame seeds
• Lime slices for garnish
• 1 teaspoon vegetable oil for the pan

Step 1: Build the sriracha lime sauce

Mix sriracha, lime juice, soy sauce, honey, sesame oil, and garlic powder together in a bowl. This sauce is bold, tangy, and has a really nice kick. Taste it right now and adjust.

Want more heat? Add extra sriracha. Want it sweeter? One more drizzle of honey. This is your sauce. Make it yours.

Step 2: Marinate for big flavor

Coat both sides of the tuna steaks generously with the sauce. Place in a dish and refrigerate for 20 minutes. Not too long or the lime juice starts to break down the fish.

Reserve a couple tablespoons of the sauce for drizzling at the end. That finishing drizzle is seriously the best part.

Step 3: Sear hot and fast

Heat a cast iron or heavy skillet over high heat with a thin layer of oil. When the oil is shimmering, add the tuna. Do not crowd the pan.

Cook 2 minutes per side for medium rare. You can go 3 minutes per side if you like it more cooked through. Honestly, medium rare is the move with tuna every single time.

Step 4: Garnish and serve

Plate the tuna and scatter sesame seeds over the top. Drizzle the reserved sriracha lime sauce over everything. Add lime slices on the side.

A final squeeze of fresh lime right before eating wakes up every single flavor in this dish. Serve with jasmine rice. You will make this one again next week, I promise.

8. Wasabi Crusted Tuna

Ingredients

• 2 tuna steaks (6 oz each, sushi grade preferred)
• 2 tablespoons wasabi paste
• 1 tablespoon soy sauce
• 1/2 cup mixed black and white sesame seeds
• 1 tablespoon vegetable oil
• 2 tablespoons soy sauce for dipping
• 1 lime, sliced
• Salt and pepper to taste

Step 1: Coat with wasabi paste

Mix wasabi paste with one tablespoon soy sauce in a small bowl. Spread this mixture evenly over all four sides of each tuna steak using a spoon or brush.

The wasabi smell is strong and that is completely normal. Once it sears, the heat mellows out and leaves this incredible savory depth behind. Trust it.

Step 2: Press on the sesame crust

Pour the sesame seeds onto a flat plate. Press each wasabi coated steak firmly into the seeds on all sides. The seeds should stick and form a thick, even crust.

This is my favorite part of the whole recipe. It goes from a plain pink steak to something that looks genuinely impressive in about 30 seconds. You’ll love this.

Step 3: Sear quickly on all sides

Heat oil in a skillet over high heat until smoking slightly. Sear the tuna for 60 to 90 seconds per side, including the thin edges. Work fast. The goal is a golden sesame crust on the outside with a rare pink center.

Do not overcook wasabi crusted tuna. The contrast between the crunchy outside and the silky rare inside is everything here. Set a timer if you need to.

Step 4: Slice and serve

Let the tuna rest for 2 minutes then slice crosswise into thick pieces. Fan them out on the plate. The pink center against the black and white sesame crust looks stunning.

Serve with soy dipping sauce, a bowl of fresh wasabi on the side, and lime wedges. Better than your favorite sushi restaurant. Seriously.

9. Mango Salsa Grilled Tuna

Ingredients

For the tuna:

• 2 tuna steaks (6 oz each)
• 2 tablespoons olive oil
• 1 teaspoon smoked paprika
• 1 teaspoon garlic powder
• Salt and black pepper to taste

For the mango salsa:

• 1 ripe mango, diced small
• 1/2 red bell pepper, diced
• 1/4 red onion, finely diced
• 1 small jalapeño, minced
• 2 tablespoons fresh cilantro, chopped
• 1 tablespoon fresh lime juice
• Salt to taste

Step 1: Make the mango salsa first

Combine diced mango, red bell pepper, red onion, jalapeño, cilantro, and lime juice in a bowl. Toss gently and season with salt. Taste it. Adjust lime or jalapeño as needed.

Make this first so the flavors have time to meld while you cook the tuna. This salsa honestly works on everything. I put it on tacos, chips, grilled chicken. It never lasts long in my house.

Step 2: Season the tuna

Drizzle olive oil over the tuna steaks and rub it in with your fingers. Sprinkle smoked paprika, garlic powder, salt, and pepper on both sides. Press gently so it sticks.

The seasoning here is intentionally simple because the mango salsa is bold enough to carry the whole dish. No need to compete.

Step 3: Grill to medium rare

Preheat your grill or grill pan over high heat. Grill the tuna 3 to 4 minutes per side. You want beautiful char marks and a seared exterior with that deep pink center.

Not sure when to flip? It should release easily from the grates on its own. If it sticks, give it another 30 seconds. It will tell you when it is ready.

Step 4: Plate with the salsa

Place the grilled tuna on a plate and spoon the mango salsa generously over the top and alongside. Slice a fresh lemon for garnish and a little squeeze over the salsa.

The sweetness of the mango against the savory tuna is such a knockout combination. This one impresses every single time. Perfect for a dinner party or a Tuesday night, honestly no difference.

10. Garlic Parmesan Grilled Tuna

Ingredients

• 2 tuna steaks (6 oz each)

• 4 cloves garlic, minced
• 3 tablespoons fresh parsley, chopped
• 2 tablespoons capers
• 1 teaspoon red chili flakes
• 1 lemon, juiced and zested
• Salt and black pepper to taste
• 2 tablespoons grated parmesan (optional but recommended)

Step 1: Build the garlic herb sauce

In a small bowl mix olive oil, minced garlic, half the parsley, capers, chili flakes, lemon zest, and lemon juice. Season with salt and pepper. Stir until combined.

This sauce is bright, garlicky, and a little punchy from the capers. Wondering if you can skip the capers? You can, but they add this briny depth that really makes it pop. Worth having them on hand.

Step 2: Coat and rest the tuna

Pat the steaks dry and spoon about half the sauce over both sides. Let the tuna rest for 10 minutes at room temperature while your pan heats up.

No need to marinate for hours. Ten minutes is genuinely enough here. The sauce is punchy enough to get the job done quickly.

Step 3: Sear in a hot skillet

Heat a skillet or grill pan over medium high heat. Add just a drizzle of oil. Place the tuna down and let it cook undisturbed for 3 minutes. Flip and cook another 2 to 3 minutes.

Okay, now the fun part. In the last 30 seconds of cooking sprinkle parmesan directly over the top of each steak while it is still in the pan. Let it melt and get a little golden. This is next level.

Step 4: Finish and serve

Spoon the remaining herb sauce over the cooked tuna right on the plate. Top with the rest of the fresh parsley.

Serve alongside a simple salad or crusty bread to soak up that sauce. Every drop of that garlic herb oil is worth chasing around the plate. You’re doing great and dinner tonight is going to be amazing.
