This is the “set it and forget it” move. It’s the slow, romantic way to thaw a fish. Take your frozen ahi—still in its vacuum-sealed bag—and plop it on a plate in the fridge.
Plan ahead, because this takes time. A thin steak? About 6 to 8 hours. A thick block? You’re looking at 12 to 24 hours. Yes, that’s an overnight date with your fridge.
Is it slow? Yes. Is it boring? Absolutely. But does it deliver a perfect, sushi-grade texture? Every single time. This method keeps the cell structure intact. Your tuna won’t weep water when you sear it.
Pro Tip for Impatient People
Okay, you didn’t plan ahead. We’ve all been there. You’re staring at a frozen brick of ahi at 5 PM. Dinner is in 90 minutes. What do you do?
You don’t cry. You reach for the cold water bath method. Keep the fish in its airtight, leak-proof bag. Seriously, check for holes. A salty fish is a sad fish.

Submerge the bag in a bowl of cold tap water. Not lukewarm. Not warm. Cold. Change the water every 20 to 30 minutes to keep it moving. A one-inch steak will thaw in about 30 to 45 minutes.
