A well-seared tuna steak is one of the quickest, most impressive things you can put on a dinner table. It takes 3 minutes total cooking time — really — and the result is a beautiful ruby-pink center surrounded by a seared, golden exterior finished in garlic butter. Tuna is a steak; treat it like one.
Ingredients
The Sear
Pat tuna completely dry. Season generously with salt and pepper on both sides. Heat a cast iron or heavy skillet over maximum heat until smoking. Oil the tuna directly, not the pan.
- Sear first side 60–90 seconds — do not move
- Flip — the steak should release cleanly; if it sticks, wait 15 more seconds
- Sear second side 60 seconds
- Immediately add butter, garlic, and thyme
- Baste continuously for 30 seconds
- Remove to a plate, rest 1 minute
- Squeeze lemon over before serving
"Tuna steak cooks in 3 minutes total. The center should be raw and cold when you cut it — that's correct, not undercooked. If you cook it through, you have expensive dry cat food. The pink center is the whole point."
For a seared raw center, use only sashimi-grade tuna from a trusted fishmonger. Sashimi-grade means it has been handled and frozen in a way that makes raw consumption safe. Standard grocery store tuna is fine if you plan to cook it through entirely, but does not work for a pink-centered preparation.
