Why This Recipe Works

The key to a great grilled tuna steak is to cook it to the right temperature. This ensures that the fish is cooked through and flaky, without being overcooked or dry. To achieve this, I recommend using an instant-read thermometer to check the internal temperature of the fish. The ideal internal temperature for grilled tuna steak is 145 F (63 C).

Another important factor is the type of tuna you use. I recommend using sashimi-grade tuna, which is typically fresher and of higher quality than other types of tuna. This will give your dish a more vibrant flavor and texture.

In addition to the type of tuna, the way you prepare the fish is also crucial. Make sure to pat the tuna dry with paper towels before grilling to remove excess moisture. This will help the fish cook more evenly and prevent it from sticking to the grill.

Finally, don't overcomplicate the recipe. Keep the seasonings simple and let the natural flavor of the tuna shine through. A squeeze of fresh lemon juice and a sprinkle of salt and pepper are all you need to bring out the best in your grilled tuna steak.

Ingredients You’ll Need

To make this recipe, you'll need a few simple ingredients. The most important ingredient is, of course, the tuna steak. I recommend using sashimi-grade tuna, which is typically fresher and of higher quality than other types of tuna. You'll also need some basic seasonings, such as salt, pepper, and lemon juice.

In addition to the tuna and seasonings, you'll need some oil to brush the grill with. I recommend using a neutral-tasting oil, such as canola or grapeseed oil, to prevent the fish from sticking to the grill.

4 tuna steaks, 6 oz (170g) eachI recommend using sashimi-grade tuna, which is typically fresher and of higher quality than other types of tuna. Make sure to choose steaks that are about 1 inch (2.5 cm) thick, as this will help them cook more evenly.
2 tbsp (30g) olive oilI recommend using a high-quality olive oil that has a mild flavor, as this will help to bring out the natural flavor of the tuna. You can also use other neutral-tasting oils, such as canola or grapeseed oil, if you prefer.
1 tsp (5g) saltI recommend using a flaky sea salt, such as Maldon or fleur de sel, as this will add a more complex flavor to the dish. You can also use regular table salt if you prefer.
1/2 tsp (2g) black pepperI recommend using freshly ground black pepper, as this will add a more vibrant flavor to the dish. You can also use pre-ground pepper if you prefer.
2 lemons, cut into wedgesI recommend using fresh lemons, as this will add a brighter flavor to the dish. You can also use bottled lemon juice if you prefer, but be aware that the flavor may not be as vibrant.
2 tbsp (30g) chopped fresh parsleyI recommend using fresh parsley, as this will add a more complex flavor to the dish. You can also use dried parsley if you prefer, but be aware that the flavor may not be as vibrant.
2 cloves garlic, mincedI recommend using fresh garlic, as this will add a more vibrant flavor to the dish. You can also use bottled garlic if you prefer, but be aware that the flavor may not be as vibrant.
1 tsp (5g) paprikaI recommend using smoked paprika, as this will add a more complex flavor to the dish. You can also use regular paprika if you prefer.
1/4 cup (60g) white wineI recommend using a dry white wine, such as Sauvignon Blanc or Pinot Grigio, as this will add a more complex flavor to the dish. You can also use chicken or fish broth if you prefer.

How to Make Grilled Tuna Steak

1
Preheat your grill to medium-high heat, about 400 F (200 C). Make sure to oil the grates with a neutral-tasting oil, such as canola or grapeseed oil, to prevent the fish from sticking.
2
In a small bowl, mix together the salt, pepper, and paprika. Sprinkle this seasoning mixture evenly over both sides of the tuna steaks.
3
Brush the grill with a neutral-tasting oil, such as canola or grapeseed oil, to prevent the fish from sticking. Place the tuna steaks on the grill and cook for 4-5 minutes per side, or until they reach an internal temperature of 145 F (63 C).
4
While the tuna is cooking, melt the butter in a small saucepan over medium heat. Add the minced garlic and cook for 1-2 minutes, or until fragrant.
5
Remove the tuna from the grill and place it on a plate or serving platter. Brush the garlic butter mixture evenly over the top of each tuna steak.
6
Squeeze a slice of lemon over the top of each tuna steak, then sprinkle with chopped parsley.
7
Serve the grilled tuna steak immediately, with your choice of sides. Some ideas include a simple salad, roasted vegetables, or a hearty grain bowl.
8
To check the internal temperature of the tuna, insert an instant-read thermometer into the thickest part of the steak. The temperature should read 145 F (63 C) for medium-rare.
9
If you prefer your tuna more well-done, cook it for an additional 1-2 minutes per side, or until it reaches your desired level of doneness.
10
Let the tuna rest for 2-3 minutes before serving, to allow the juices to redistribute and the fish to retain its moisture.
11
Serve the grilled tuna steak with your choice of sides, and enjoy!

The grilled tuna steak is a versatile dish that can be served with a variety of sides. Some ideas include a simple salad, roasted vegetables, or a hearty grain bowl. You could also serve it with a side of steamed vegetables or a rich and creamy sauce, such as a beurre blanc or a hollandaise.

One of my favorite ways to serve the grilled tuna steak is with a simple salad of mixed greens, cherry tomatoes, and a light vinaigrette. The acidity of the vinaigrette helps to cut through the richness of the tuna, while the mixed greens and cherry tomatoes add some color and texture to the dish.

Make-Ahead, Storage, Freezing and Reheating

If you're not planning to serve the grilled tuna steak immediately, you can store it in the refrigerator for up to 24 hours. Simply place the tuna in an airtight container and refrigerate at a temperature of 40 F (4 C) or below.

To reheat the tuna, simply place it in a pan over medium heat and cook for 2-3 minutes per side, or until it reaches an internal temperature of 145 F (63 C). You can also reheat it in the oven at 350 F (180 C) for 5-7 minutes, or until it reaches the desired temperature.

If you're planning to freeze the tuna, I recommend wrapping it tightly in plastic wrap or aluminum foil and placing it in a freezer-safe bag. The tuna can be frozen for up to 3 months at a temperature of 0 F (-18 C) or below.

To thaw the tuna, simply place it in the refrigerator overnight or thaw it quickly by submerging it in cold water. Once thawed, the tuna can be reheated and served as desired.
