Ingredients

Main Ingredients

• 2 (6-8 ounce each) tuna steaks, 1-inch thick – sushi-grade or high-quality, fresh, deep red
• 1 tablespoon olive oil, or avocado oil – for searing
• 1/2 teaspoon sea salt – fine grain
• 1/4 teaspoon freshly ground black pepper – to taste

For the Lemon-Herb Drizzle

• 1/4 cup extra virgin olive oil – good quality, fruity
• 2 tablespoons fresh lemon juice – from about 1 medium lemon
• 1 tablespoon fresh parsley, finely chopped – flat-leaf preferred
• 1 tablespoon fresh chives, finely chopped – delicate oniony flavor
• 1 clove garlic, minced very fine – adds aromatic depth
• 1/4 teaspoon sea salt – or to taste
• Pinch red pepper flakes (optional) – for a subtle warmth

Tuna Steaks: The star of the show! Opt for sushi-grade tuna if you can find it, especially if you prefer it very rare. Its deep red color indicates freshness and quality. Look for steaks that are uniform in thickness, about 1 inch, to ensure even cooking. If your steaks are thicker, adjust cooking time slightly.

Olive Oil: For searing, a high smoke point oil is essential. Regular olive oil or avocado oil works beautifully. For the drizzle, extra virgin olive oil adds a rich, fruity base that complements the herbs and lemon.

Lemon Juice: Freshly squeezed lemon juice is non-negotiable here. It provides that bright, zesty acidity that cuts through the richness of the tuna and awakens the palate. Bottled lemon juice just won’t give you the same vibrant flavor.

Fresh Herbs: Parsley and chives bring a beautiful freshness and delicate oniony notes to the drizzle. Their vibrant green color also adds visual appeal. Feel free to experiment with other soft herbs like dill or tarragon if you’re feeling adventurous.

Garlic: Just one clove, finely minced, adds a wonderful aromatic depth to the sauce without overpowering the delicate tuna. It’s a subtle background player that makes a big difference.

Pro Tips

1. Pat it Dry, Really Dry: Before seasoning, use paper towels to thoroughly pat dry your tuna steaks. Any surface moisture will prevent a good sear and a beautiful crust. This is crucial for that restaurant-quality finish.
2. Hot Pan, Quick Sear: The key to perfectly seared tuna is a screaming hot pan and a very quick cook time. You want a beautiful, caramelized crust on the outside and a rare to medium-rare center. Don’t overcrowd the pan; cook in batches if necessary.
3. Don’t Overcook: Tuna cooks incredibly fast. Aim for an internal temperature of 115-125°F (46-52°C) for rare, or 125-135°F (52-57°C) for medium-rare. Any more than that, and your tuna will become dry and tough. A meat thermometer is your best friend here.

Instructions

Step 1: Prepare the Tuna Steaks

Begin by removing your tuna steaks from the refrigerator about 15 minutes before cooking. This allows them to come closer to room temperature, promoting more even cooking. Use paper towels to thoroughly pat dry each tuna steak. This step is vital for achieving a good sear. Season both sides of the steaks generously with 1/2 teaspoon sea salt and 1/4 teaspoon freshly ground black pepper.

Step 2: Make the Lemon-Herb Drizzle

While the tuna rests, prepare the vibrant drizzle. In a small mixing bowl, combine 1/4 cup extra virgin olive oil, 2 tablespoons fresh lemon juice, 1 tablespoon finely chopped fresh parsley, 1 tablespoon finely chopped fresh chives, and 1 clove finely minced garlic. Whisk these ingredients together until well combined. Taste and adjust seasoning, adding more sea salt or a pinch of red pepper flakes if desired. Set aside.

Step 3: Sear the Tuna

Heat a heavy-bottomed skillet, preferably cast iron, over high heat until it is smoking lightly, about 3-4 minutes. You want it very hot. Add 1 tablespoon olive oil to the pan and swirl to coat the bottom. Carefully place the seasoned tuna steaks into the hot pan. You should hear a strong sizzle immediately. Sear for 1.5 to 2 minutes per side for rare to medium-rare, depending on your preferred doneness and the thickness of the steak. For a medium-rare steak, the outside will be opaque and golden-brown, while the center remains pink and tender. If using a meat thermometer, aim for an internal temperature of 115-125°F (46-52°C) for rare, or 125-135°F (52-57°C) for medium-rare.

Step 4: Rest and Serve

Once seared to your liking, carefully remove the tuna steaks from the pan and transfer them to a clean cutting board or plate. Allow the tuna to rest for 2-3 minutes. This crucial step allows the juices to redistribute, ensuring a tender and moist steak. Resting prevents the tuna from drying out when sliced. Slice the tuna against the grain into thick pieces, if desired, or serve whole. Drizzle generously with the prepared lemon-herb sauce just before serving.

Serving & Storage

Serving Suggestions

This seared tuna steak is a showstopper on its own. For plating, arrange the sliced tuna artfully on a bed of fresh greens or alongside vibrant vegetables. A sprinkle of fresh herbs on top adds a final touch of elegance.

Best side dishes include roasted asparagus, garlicky green beans, a light quinoa salad, or a simple couscous with roasted vegetables. For a heartier meal, serve it with roasted baby potatoes or a creamy cauliflower mash.

Pair this dish with a sparkling lemon-lime soda, a refreshing ginger mocktail, or a crisp, non-alcoholic sparkling cider. Herbal iced tea, like mint or hibiscus, would also be a lovely complement.

Storage Instructions

• Refrigerator: Leftover seared tuna, tightly wrapped in an airtight container, can be stored in the refrigerator for up to 2 days. While still delicious, the texture will be firmer and less rare than when freshly cooked.
• Freezer: Freezing cooked tuna is not recommended. The texture will significantly degrade upon thawing, becoming dry and fibrous. Enjoy it fresh!
• Reheating: To reheat, gently warm the tuna in a pan over low heat for just a few minutes, or in the microwave on a low setting for short bursts. Be careful not to overcook it, as it will dry out quickly. It’s often best enjoyed chilled or at room temperature if not freshly seared.

Frequently Asked Questions

1. How do I know if my tuna is sushi-grade?

“Sushi-grade” is not a regulated term, but generally, it refers to tuna that has been caught, handled, and stored with extreme care to be safe for raw consumption. Look for tuna that is vibrant, deep red in color, with no brown spots or discoloration. It should have a fresh, mild ocean smell. Buy from a reputable fishmonger and ask them directly if it’s suitable for raw preparation.

2. Can I use frozen tuna steaks for this recipe?

Yes, you can use frozen tuna steaks. The key is to thaw them properly. Transfer the frozen steaks to the refrigerator the night before you plan to cook them. Once thawed, pat them very dry with paper towels before seasoning and searing. Proper thawing and drying are crucial for good texture and a proper sear.

3. What if I don’t have a cast-iron skillet?

While a cast-iron skillet is ideal for its heat retention and even cooking, any heavy-bottomed skillet will work well. Stainless steel or a good quality non-stick pan can also achieve a great sear. Just ensure your pan is very hot before adding the tuna, and adjust the heat as needed to maintain a consistent high temperature.

4. Why is resting the tuna important?

Resting meat, including fish, allows the internal juices, which have been pushed to the center during cooking, to redistribute throughout the steak. If you slice it immediately, these juices will run out, resulting in a drier, less flavorful piece of tuna. A short rest ensures a more tender, moist, and delicious steak.

5. Can I prepare the lemon-herb drizzle ahead of time?

Absolutely! The lemon-herb drizzle can be made up to 24 hours in advance. Store it in an airtight container in the refrigerator. Before serving, allow it to come to room temperature and give it a good whisk to re-emulsify the ingredients. This makes meal prep a breeze!
