Why Grilled Tuna Steak?
Grilled tuna steak is a healthy, protein-packed meal that’s incredibly versatile. Rich in omega-3 fatty acids and essential nutrients, tuna steaks are perfect for a nutritious dinner, whether served over a bed of salad, with a side of grilled vegetables, or as the main star of a Mediterranean-inspired meal. Tuna is also sustainable when sourced responsibly, adding an eco-friendly element to your culinary pursuits.
Tips and Tricks for Perfect Grilled Tuna Steak
- High Heat Is Key: Tuna steaks cook quickly, so a hot grill is essential for a good sear without overcooking.
- Don’t Overcook: Tuna becomes dry and chewy when overcooked. Aim for a seared exterior and a rare to medium-rare interior for the best texture.
- Let It Rest: Let the grilled tuna rest for a few minutes before slicing. This helps lock in the juices.
How to Serve Grilled Tuna Steak
- Simple and Classic: With a drizzle of homemade chimichurri sauce or a squeeze of fresh lemon.
- Asian-Inspired: Serve with a wasabi mayo drizzle, pickled ginger, and a side of sticky rice.
- Mediterranean Feast: Pair with a Greek salad, tzatziki sauce, and grilled pita bread.
- Over a Bed of Greens: A fresh arugula salad with shaved Parmesan and a balsamic glaze is a light and flavorful option.

Variations to Try
- Sesame-Crusted Tuna: Before grilling, coat the tuna steak with a mix of black and white sesame seeds for a nutty crunch.
- Blackened Tuna: Rub the tuna steak with Cajun spices for a bold, smoky flavor.
- Citrus-Marinated Tuna: Soak the tuna in a mix of orange and lime juice with fresh herbs for a bright, zesty flavor.
How to Store Grilled Tuna Steak
- Refrigeration: Store any leftover tuna steak in an airtight container for up to 2 days. Keep in mind that reheating may dry it out, so it’s best served cold over a salad.
- Freezing: Tuna steak can be frozen, but the texture may change slightly. Wrap tightly in plastic wrap and then foil before placing in the freezer for up to 3 months.

Grilled Tuna Steak

Grilled Tuna Steak is a simple yet flavorful dish that brings out the natural taste of fresh tuna. The steak is lightly seasoned with salt, pepper, and a drizzle of olive oil before being grilled to perfection.
Ingredients
For the Tuna & Seasoning:
- 2 ahi tuna steaks (about 1 pound)
- 2 tablespoons olive oil
- Kosher salt & freshly ground black pepper
- Sesame seeds, to taste
- Thinly sliced green onion, for garnish
For the Dipping Sauce:
- 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
Instructions
- In a medium bowl, whisk together soy sauce, rice vinegar, and honey until the honey dissolves. Add in the toasted sesame oil, grated ginger, and minced garlic. Whisk until smooth and emulsified. Set aside at room temperature or refrigerate for later.
- Preheat your gas or charcoal grill to high heat. You want it scorching hot to get that perfect sear.
- Rinse the tuna steaks and pat them completely dry with paper towels. Rub both sides generously with olive oil, then season with kosher salt and freshly ground black pepper.
- Place the tuna steaks directly on the hot grill grates. Grill for about 2 minutes per side to get a gorgeous sear, leaving the center rare and juicy. If you prefer a more cooked center, add an extra minute or two per side.
- Once done, transfer the tuna to a cutting board and slice thinly across the grain with a sharp knife (about 1/4 to 1/2-inch slices).
- Sprinkle with sesame seeds and sliced green onion.
- Arrange on a platter and serve alongside the dipping sauce. Enjoy every delicious bite!
