You’ve probably heard this old gem: cook fish for 10 minutes per inch of thickness. And you know what? It’s not terrible—as a starting point. At 400°F, that rule actually works pretty well. But I’m here to tell you: your thermometer is your best friend. Don’t be a hero. The FDA says fish is done at 145°F internally. But here’s the pro tip: take it out at 140°F. Carryover heat will push it to 145°F while it rests. That’s how you avoid the dry-gym-towel situation.

I know, I know—pulling out a thermometer feels geeky. But you know what’s even geekier? Serving dry fish to your in-laws and watching them take one polite bite and push it around the plate. Just do it. Invest $10 in a digital thermometer. Your fish will go from fine to phenomenal. And you’ll feel like a kitchen wizard.
Pan-Frying is a Different Beast
Let’s shift gears for a sec. Maybe you’re not an oven person. Maybe you’re a stovetop rebel who likes to sizzle. Cool. For pan-frying, you want medium-high heat, generally around 375°F to 400°F on the surface. Drop a drop of water in the pan—if it dances and evaporates instantly, you’re ready. But here’s the thing: don’t crowd the pan. If you pile in three fillets, the temperature plummets, and you get steamed fish. Save that for bamboo baskets.
And please, pat your fish dry before it hits the oil. Wet fish is sad fish. It sticks, it splatters, and it robs you of that beautiful golden crust. I learned this the hard way when my roommate walked in to find me swearing at a stuck-to-the-pan piece of cod. Not my finest moment.
