What you’ll need

• 2 tuna steaks (6-8 oz each)
• 2 tablespoons olive oil (or high smoke point oil like canola or grapeseed)
• Salt and freshly ground black pepper to taste
• 1 tablespoon unsalted butter
• 1 clove garlic, minced
• 1 tablespoon lemon juice
• 1 tablespoon chopped fresh parsley (optional)
• Lemon wedges for serving

How to cook tuna steak: step by step

1. Remove the tuna steaks from the refrigerator and let them sit at room temperature for about 15-20 minutes to take the chill off. This helps ensure even cooking.
2. Pat the tuna steaks dry with paper towels to remove excess moisture. This step is crucial for achieving a good sear.
3. Season both sides of the tuna steaks generously with salt and freshly ground black pepper. You can also add other seasonings like garlic powder, onion powder, or a sprinkle of chili flakes if desired.
4. Heat a heavy skillet (preferably cast iron) over medium-high heat. Add the olive oil and let it heat until it shimmers but not smoking.
5. Carefully place the tuna steaks in the hot skillet. Sear for 2-3 minutes on the first side, without moving them, to develop a nice crust.
6. Flip the tuna steaks using tongs and sear for an additional 2-3 minutes on the second side. For rare tuna, cook to an internal temperature of 115-125F (46-52C). For medium-rare, cook to 125-130F (52-54C) and for medium, cook to 130-140F (54-60C).
7. Add the butter, minced garlic, and lemon juice to the skillet. Tilt the pan slightly to pool the butter and use a spoon to baste the tuna steaks with the melted butter mixture for about 30 seconds.
8. Remove the tuna steaks from the skillet and let them rest for 3-5 minutes. This resting period allows the juices to redistribute, ensuring a moist and flavorful steak.
9. Garnish the tuna steaks with chopped fresh parsley if desired and serve with lemon wedges on the side for squeezing over the top.

How to know when it’s done

The doneness of tuna steak is a matter of personal preference, but it is generally recommended to cook it to medium-rare for the best balance of flavor and texture. Tuna cooked to rare (115-125F/46-52C) will have a very pink center and a soft, almost sashimi-like texture. Medium-rare (125-130F/52-54C) will have a warm, pink center with a slightly firmer texture, while medium (130-140F/54-60C) will have a more opaque pink center and a more robust flavor. Avoid cooking tuna steak beyond medium, as it can become dry and lose its delicate flavor. Use a reliable meat thermometer to check the internal temperature and avoid overcooking.

When cooking tuna steak, it’s important to achieve a good sear on the outside while maintaining a tender, juicy interior. The high heat used for searing helps create a flavorful crust, while the quick cooking time preserves the steak’s natural moisture. If you prefer your tuna steak more well-done, consider marinating it beforehand to help retain moisture and flavor. However, be mindful that overcooking can cause the tuna to become tough and less enjoyable.

Tips for the best tuna steak

For the best results, choose fresh, high-quality tuna steaks. Look for steaks that are firm, have a vibrant color, and smell fresh and clean, not fishy. If possible, buy sushi-grade tuna for the highest quality.

Allow the tuna steaks to come to room temperature before cooking. This helps ensure even cooking and prevents the steaks from seizing up when they hit the hot pan. This step is particularly important if you plan to cook the tuna to rare or medium-rare.

Use a heavy skillet, such as cast iron, for searing tuna steaks. The even heat distribution and excellent heat retention of cast iron help achieve a perfect sear. Avoid using non-stick pans, as they can’t withstand the high heat needed for searing.

Basting the tuna steaks with butter and garlic adds richness and depth of flavor. For an extra layer of flavor, you can also add herbs like thyme or rosemary to the butter mixture. Be careful not to burn the garlic, as it can turn bitter.

Variations & other methods

For a more flavorful tuna steak, consider marinating the steaks for 15-30 minutes before cooking. A simple marinade of soy sauce, sesame oil, ginger, and garlic can add an Asian twist to your dish. Alternatively, a marinade of olive oil, lemon juice, and herbs like thyme or rosemary can give the tuna a Mediterranean flair.

If you want to add some heat to your tuna steak, sprinkle a pinch of chili flakes or a dash of hot sauce into the butter and garlic mixture. You can also add a touch of honey or maple syrup to balance the heat with sweetness.

For a smoky flavor, try grilling the tuna steaks instead of pan-searing. Preheat your grill to high heat and oil the grates to prevent sticking. Grill the tuna steaks for 2-3 minutes per side, or until they reach your desired level of doneness. Grilling adds a delicious smoky char to the tuna and is perfect for outdoor cooking.

What to serve with it

Tuna steak is a versatile dish that can be served in a variety of ways. For a simple yet elegant presentation, serve the tuna steaks with a side of roasted vegetables or a fresh green salad. The acidity of a lemon vinaigrette or a tangy yogurt dressing can complement the rich flavor of the tuna.

For a more substantial meal, serve the tuna steaks with a side of quinoa, brown rice, or roasted potatoes. You can also add a creamy sauce, such as a lemon-caper butter sauce or a spicy aioli, to enhance the dish. For a low-carb option, serve the tuna steaks over a bed of arugula or spinach.

Storing & reheating

If you have leftover cooked tuna steak, store it in an airtight container in the refrigerator for up to 2 days. To reheat, place the tuna steak in a preheated oven at 350F (175C) for 5-7 minutes, or until heated through. Avoid microwaving, as it can dry out the tuna.

For raw tuna steaks, store them in the refrigerator for up to 2 days. If you plan to store them for longer, wrap the steaks tightly in plastic wrap and place them in the freezer for up to 3 months. To thaw, transfer the steaks to the refrigerator and let them thaw overnight. Do not refreeze previously frozen tuna.

Common mistakes to avoid

One of the most common mistakes when cooking tuna steak is overcooking it. Overcooking can cause the tuna to become dry and lose its delicate flavor. To avoid this, use a meat thermometer to check the internal temperature and remove the steaks from the heat when they reach the desired level of doneness.

Another mistake is not allowing the tuna steaks to come to room temperature before cooking. This can lead to uneven cooking and result in a steak that is overcooked on the outside and undercooked on the inside. Always let the steaks sit at room temperature for 15-20 minutes before cooking.
