Ingredients
• 2 tuna steaks (6 oz each, 1″ thick; sushi-grade, wild-caught if possible)
• 2 tbsp extra-virgin olive oil (I love Colavita for its peppery kick)
• 1 tsp fine sea salt (Maldon flaky salt works beautifully)
• ½ tsp freshly ground black pepper
• 1 tsp dried oregano (or 1 Tbsp fresh, finely chopped)
• Zest and juice of 1 medium lemon (about 2 Tbsp juice)
• 2 garlic cloves, minced (add at the end to avoid burning)
• ¼ cup quartered cherry tomatoes (optional garnish)
• Fresh parsley or basil for garnish (sub fresh thyme if you like)
Tip: Let tuna rest at room temperature for 15 minutes—this helps it cook evenly and develop a gorgeous crust.
Directions
1. Pat tuna steaks dry with paper towels, then brush both sides lightly with olive oil. Season evenly with salt, pepper, and oregano. Tip: Removing excess moisture is key to a crisp sear.
2. Preheat your grill to medium-high heat (about 450°F) or set a heavy-bottomed skillet—cast-iron preferred—over medium-high on the stove until it shimmers.
3. Place tuna on the cooking surface. Grill or sear for 2 minutes per side for rare, 3 minutes per side for medium. Resist the urge to flip more than once—this builds that beautiful crust.
4. During the last 30 seconds, sprinkle minced garlic around the steaks (not directly under them) so it softens without charring. You’ll get that mellow garlic aroma without the bitter bite.
5. Remove steaks to a plate, tent loosely with foil, and let rest for 5 minutes. Resting locks in juices—trust me, it makes a difference.
6. Drizzle with fresh lemon juice, scatter cherry tomatoes and herbs, then slice against the grain. Serve immediately with grilled veggies or a crisp salad.
Servings & Timing
Yield: Serves 2
Prep Time: 10 minutes (plus 15 minutes resting)
Cook Time: 6 minutes
Rest Time: 5 minutes
Total Time: about 36 minutes
Variations
• Spicy Citrus: Add ¼ tsp red pepper flakes and 1 Tbsp orange juice for a zesty kick.
• Mediterranean Platter: Serve on a bed of cucumber, olives, feta, and a drizzle of tzatziki.
• Herb-Crust Twist: Press finely chopped rosemary and thyme onto steaks before cooking.
• Miso-Ginger Glaze: Swap lemon for 2 Tbsp white miso paste mixed with grated ginger.
• Keto-Style: Skip tomatoes, pair with cauliflower rice and avocado slices.
• Gluten-Free Soy Swap: Use tamari or coconut aminos in place of Worcestershire sauce if you add it.
Storage & Reheating
• Refrigerator: Store cooled tuna in an airtight container for up to 3 days.
• Freezer: Not ideal—tuna texture changes, but you can freeze cooked steaks up to 1 month; thaw overnight in fridge.
• Reheating: Gently warm in a skillet over low heat for 1–2 minutes per side, or enjoy cold in salads and wraps.
• Make-Ahead: Season and marinate steaks up to 2 hours ahead, covered in the fridge.
Notes
• I learned that adding garlic too early causes a bitter taste—sprinkle it in the final moments.
• For a deeper sear, pat steaks extra-dry and preheat your pan longer—cast-iron really helps.
• If your steaks are thicker than 1″, add 1 minute per side, but watch carefully or they’ll overcook.
• Sea-salt flakes on the finished steak add a gourmet touch and pop of texture.
FAQs
Q: Can I use frozen tuna steaks?
A: Yes—thaw fully in the fridge overnight, then pat dry before seasoning to avoid sogginess.
Q: How do I know when it’s cooked just right?
A: Aim for an internal temperature of 125°F for medium-rare; the center should still be slightly translucent.
Q: Can I marinate the tuna longer?
A: Up to 30 minutes—beyond that, the acid from lemon juice can start “cooking” the fish and altering texture.
Q: Is this recipe gluten-free?
A: Absolutely—just skip any soy-based sauces or ensure they’re certified gluten-free.
Q: What sides pair best?
A: A crisp green salad, quinoa tabbouleh, or grilled asparagus complement the Mediterranean vibe.
Q: Why does my tuna turn gray?
A: Overcooking or not removing moisture can cause that—keep cook times short and temp high.
Q: Can I swap tuna for another fish?
A: Salmon or swordfish work well, but adjust cooking times—salmon needs a minute or two more per side.
Q: How can I reduce mercury concerns?
A: Choose smaller tuna species like skipjack or check labels for “low-mercury” certification.
