Step 1: How to Prepare Tuna Loin for Cooking

✅ Start with a high-quality tuna loin – Fresh or frozen sushi-grade tuna works best.
✅ Rinse under cold water to remove any surface residue.
✅ Pat dry with paper towels to remove excess moisture—this is crucial for a good sear!
✅ Season generously with salt and black pepper on both sides.

👉 Pro Tip: If using frozen tuna, thaw it overnight in the refrigerator for the best texture.

Step 2: Marinating the Tuna Loin for Maximum Flavor

1️⃣ In a mixing bowl, whisk together:
✅ Olive oil
✅ Fresh lemon juice
✅ Crushed garlic cloves
✅ Chopped fresh herbs (thyme, parsley, or basil)
2️⃣ Place the tuna loin in a shallow dish and pour the marinade over it.
3️⃣ Cover and refrigerate for at least 30 minutes (or up to 2 hours for deeper flavor).

👉 Why marinate? This process enhances the flavor, tenderizes the fish, and locks in moisture.

Step 3: Searing the Tuna Loin for a Perfect Crust

1️⃣ Heat a cast-iron skillet or grill pan over medium-high heat.
2️⃣ Drizzle with olive oil to prevent sticking.
3️⃣ Place the tuna loin in the pan and sear for 2-3 minutes per side.
4️⃣ Flip once to avoid overcooking—it should be golden brown on the outside and slightly pink in the center.

👉 Cooking Tips:
✔️ For rare tuna: Sear for 1-2 minutes per side.
✔️ For medium-rare: Sear for 2-3 minutes per side.
✔️ For well-done: Sear for 4-5 minutes per side (but be careful—overcooked tuna can become dry).
