Ingredients

• Tuna Steaks (2 x 200g / 7oz): We’re using two tuna steaks, each weighing approximately 200 grams (7 ounces) and about 1½ inches thick. Look for sushi-grade tuna steaks with a vibrant red color and firm texture. This ensures the best flavor and safety. Yellowfin or Bigeye tuna are excellent choices for searing.
• Kosher Salt (1 tsp / 5g): Kosher salt is preferred for seasoning as its larger crystals distribute flavor more evenly and help draw out moisture, contributing to a better sear. We’re using 1 teaspoon (5 grams) to season the tuna.
• Freshly Ground Black Pepper (½ tsp / 2g): Freshly ground black pepper provides a more robust and aromatic flavor than pre-ground pepper. ½ teaspoon (2 grams) will add a subtle spice to complement the tuna and garlic butter.
• Olive Oil (2 tbsp / 30ml): We’re using 2 tablespoons (30ml) of olive oil for searing the tuna. Choose a good quality olive oil with a high smoke point, like extra virgin olive oil, to prevent burning.
• Unsalted Butter (2 tbsp / 30g): The foundation of our flavorful sauce! 30 grams (2 tablespoons) of unsalted butter allows us to control the saltiness of the dish. Using unsalted butter also allows the garlic and lemon flavors to shine through.
• Garlic Cloves (2, minced ≈10g): Freshly minced garlic is essential for that classic garlic butter flavor. We’re using 2 cloves (approximately 10 grams), minced finely to release their aromatic oils.
• Lemon Zest (½ lemon ≈1g): The zest of ½ lemon adds a bright, citrusy aroma and flavor to the garlic butter. Be sure to zest only the yellow part of the peel, avoiding the white pith which can be bitter.
• Freshly Squeezed Lemon Juice (1 tsp / 5ml): A teaspoon (5ml) of freshly squeezed lemon juice brightens the finished dish and balances the richness of the butter.
• Flat-Leaf Parsley (1 tbsp / 15ml, chopped): Chopped flat-leaf parsley provides a fresh, herbaceous garnish and a pop of color. Italian flat-leaf parsley is preferred for its flavor.
• Toasted Black Sesame Seeds (1 tbsp / 8g): Toasted black sesame seeds add a nutty flavor and a beautiful visual contrast. Toasting the seeds enhances their flavor and aroma.

Ingredient Substitutions

While this recipe is fantastic as written, here are a few substitutions you can make:

• Tuna Steaks: If you can’t find tuna, swordfish or salmon steaks can be used as a substitute, though cooking times may vary.
• Olive Oil: Avocado oil or grapeseed oil can be used in place of olive oil.
• Lemon: Lime can be used in place of lemon for a slightly different citrus flavor.
• Parsley: Chives or cilantro can be used as a garnish instead of parsley.

Optional (plan-ahead): If you’re shopping for the week, I put this into a 4-Week Meal Plan + Grocery Lists so dinner’s already decided before your day gets busy.

How to Sear Tuna Steak to Perfection: A Step-by-Step Guide

1. Pat the Tuna Steaks Dry: This is arguably the most crucial step! Tuna contains a lot of moisture. Using paper towels, thoroughly pat both sides of each tuna steak dry. This removes surface moisture, allowing for a beautiful, flavorful sear instead of steaming.
2. Season Generously: Season both sides of each tuna steak liberally with kosher salt and freshly ground black pepper. Don’t be shy – tuna can handle a good amount of seasoning. Let the steaks rest for about 2 minutes after seasoning. This allows the salt to penetrate the fish, enhancing its flavor and helping to retain moisture during cooking.
3. Heat the Skillet: Choose a heavy-bottomed skillet – cast iron is ideal, but stainless steel will also work. Place the skillet over medium-high heat. The pan needs to be *hot* before adding the oil. Test the heat by flicking a tiny drop of water into the pan; it should sizzle and evaporate almost immediately.
4. Add Olive Oil: Once the skillet is hot, add the olive oil. Swirl the pan to ensure the oil coats the entire surface evenly. The oil prevents the tuna from sticking and contributes to the sear.
5. Sear the Tuna: Carefully place the tuna steaks into the hot skillet. Resist the urge to move them! Sear for 2 minutes without disturbing them. This allows a golden-brown crust to form. After 2 minutes, flip the steaks and sear for another 1-2 minutes, depending on your desired level of doneness.
6. Create the Garlic Butter Sauce: Add the butter, minced garlic, and lemon zest to the pan. As the butter melts, tilt the pan slightly and use a spoon to continuously baste the tuna steaks with the aromatic garlic butter. This infuses the tuna with incredible flavor and keeps it moist. If using, add a pinch of smoked paprika for a subtle smoky note.
7. Rest the Tuna: Remove the tuna steaks from the skillet and place them on a warm plate. Drizzle with freshly squeezed lemon juice. Let the steaks rest for 2 minutes. This allows the internal temperature to equalize, resulting in a more tender and flavorful steak.
8. Finish and Plate: While the tuna rests, whisk any remaining pan butter into a glossy drizzle. Plate each steak on a white ceramic plate. Fan the garlic butter drizzle across the top of each steak. Scatter chopped parsley and toasted black sesame seeds over the tuna. Garnish with a thin lemon wedge for a pop of color and added brightness. Finish with a light dusting of extra lemon zest.

Understanding Tuna Doneness

Tuna is best served medium-rare to medium. Overcooking will result in a dry, tough steak. Here’s a guide:

• Rare: 125°F (52°C) – Deep red center
• Medium-Rare: 130-135°F (54-57°C) – Warm red center
• Medium: 140°F (60°C) – Pink center
• Medium-Well: 145°F (63°C) – Slightly pink center
• Well-Done: 155°F (68°C) – No pink

Use an instant-read thermometer to ensure accurate doneness. Remember that the tuna will continue to cook slightly during the resting period.

Why Garlic Butter and Tuna are a Match Made in Heaven

The combination of garlic butter and tuna is a classic for a reason. The richness of the butter complements the lean protein of the tuna, while the garlic adds a pungent, savory depth. Lemon juice cuts through the richness, providing a bright, acidic balance. This sauce isn’t just about flavor; the basting technique ensures the tuna stays incredibly moist and tender during the searing process. The aromatics infuse the fish, creating a truly unforgettable culinary experience.

Selecting the Best Tuna Steaks

When purchasing tuna steaks, look for steaks that are firm to the touch and have a vibrant, reddish-pink color. Avoid steaks that appear brown or have a fishy odor. Sashimi-grade tuna is ideal, but not always necessary for searing. The thickness of the steak is also important; aim for steaks that are at least 1 ½ inches thick to prevent overcooking. Consider the source – sustainably sourced tuna is always the best choice.

Frequently Asked Questions (FAQ)

How do I prevent the garlic from burning?

Adding the garlic towards the end of the searing process and continuously basting the tuna with the butter helps prevent the garlic from burning.
