Cooking steps
  1. 1

    Pat the tuna steaks dry with paper towels and brush both sides with 1 tablespoon olive oil. Season with half of the kosher salt and all the black pepper.

  2. 2

    Heat a heavy skillet (preferably cast iron or stainless steel) over high heat until almost smoking.

  3. 3

    Add the tuna steaks to the dry, hot skillet and sear for exactly 2 minutes per side for medium-rare; adjust time for preferred doneness but avoid overcooking.

  4. 4

    While the tuna cooks, combine diced avocado, cherry tomatoes, red onion, cilantro, lime juice, remaining olive oil, and the rest of the salt in a medium bowl. Gently stir to keep avocado intact.

  5. 5

    Transfer the seared tuna steaks onto plates and top immediately with the fresh avocado salsa. Serve at once for best flavor and texture.

Personalized Q&A
Q. What's the key ingredient in this recipe?
The core ingredient here is fresh tuna steak, which delivers the high-quality protein and meaty texture that make this dinner special. The avocado adds creaminess, while the salsa brings freshness and color.
Q. How do I get a perfect sear on the tuna steak?
The secret is in heat control: use a heavy, hot skillet and only oil the tuna, not the pan. Sear for exactly 2 minutes per side on high heat for medium-rare; don't overcrowd the pan, and let the steaks form a golden crust before flipping.
Q. How do I keep the tuna tender and not dry?
Avoid overcooking—sear just 2 minutes per side for medium-rare. Letting the steaks rest for 1-2 minutes after searing also helps juices redistribute, ensuring each bite stays moist.
