Let’s be honest, you don’t need a deep fryer—a heavy-bottomed pot or a cast-iron skillet works perfectly. Use an oil with a high smoke point, like canola, peanut, or avocado oil. Olive oil is for salads, not crispy fish—it burns at around 375°F, which is exactly where you’re cooking.
For the batter? Keep it simple: cornmeal, flour, or a beer batter all work, but make sure your fish is patted bone-dry before coating. Moisture is the enemy of crispiness—it creates steam that pushes the batter off. Pat it dry like you’re giving it a spa treatment.
One more thing: a digital thermometer with a probe is a game-changer. You can check the oil temp in seconds, and nothing ruins a fry session like a liar’s thermometer. “Oh, it’s fine” is what I told myself before eating burnt fish. Don’t be me.

How to tell when it’s done (without a degree in fishology)
You don’t need to guess. The fish is ready when it’s golden brown and flakes easily with a fork. For most fillets, that’s about 4 to 6 minutes total, flipping once halfway. If you’re fancy, use an instant-read thermometer—fish is done at 145°F internal.
But here’s a pro tip: take it out just before it hits 145°F, because carryover cooking will finish the job. Otherwise, you’ll get dry, stringy fish that tastes like cardboard. Nobody wants that.
And yes, let it rest on a wire rack for a minute—not on paper towels, which trap steam and kill the crunch. You want a crispy crust that audibly crunches when you bite in. That’s the sound of victory.
