Step-by-Step Instructions

Step 1: Marinate Your Fish

Pat the fish fillets dry with a paper towel, then place them in a bowl. Mix the soy sauce, minced garlic, and fresh ginger in a small bowl, then pour it over the fish. Let it sit for 15 minutes, no longer, this keeps the fish tender while the flavors soak in.

Step 2: Make Your Crispy Coating

While the fish marinates, combine the cornstarch, gochugaru, rice flour, and salt in a shallow bowl. The rice flour is your secret ingredient here, it makes the coating extra crispy and helps the gochugaru stick beautifully to every surface. Mix it all together until you have one unified dry coating.

Step 3: Prepare Your Oil

Heat about 1.5 to 2 inches of oil in a deep skillet or small pot to 350 degrees Fahrenheit. The oil needs to be hot enough to create that shatteringly crisp exterior in just a few minutes. Use a thermometer if you have one, or test with a small piece of bread, it should brown in about 60 seconds.

Step 4: Coat and Fry

Remove each fish fillet from the marinade and let any excess liquid drip off. Working quickly, coat the fillet thoroughly in the gochugaru mixture on all sides. Carefully place it in the hot oil. Fry for 3 to 4 minutes until the coating is deep red and shatteringly crispy, then flip and fry the other side for another 2 to 3 minutes. The fish should be golden brown underneath all that gorgeous red pepper coating.

Step 5: Drain and Rest

Use a slotted spoon to transfer the fried fish to a plate lined with paper towels. Let it rest for a minute, this keeps the coating crispy instead of getting soggy.

Step 6: Make Your Dipping Sauce

Whisk together the soy sauce, sesame oil, and rice vinegar. Pour it into a small bowl and top with sliced green onions. This is your perfect companion to the fried fish.

Pro Tips for Perfect Results

Keep your oil temperature consistent. If it drops below 325 degrees, your coating will absorb oil instead of crisping up. If it goes above 375, your coating will burn before the fish cooks through. A thermometer is your best friend here.

Don’t skip the rice flour in your coating mixture. That small amount makes a real difference in texture, it gives you that extra-crispy shell that makes people take notice.

Pat your fish dry before marinating and again before coating. Any extra moisture is the enemy of crispiness, so don’t skip this step.

If you’re frying multiple fillets, let your oil come back to temperature between batches. This takes about 2 to 3 minutes and ensures every piece gets the same beautiful crust.

Storage and Reheating

Store leftover fried fish in an airtight container in the refrigerator for up to 2 days. To reheat and keep the coating crispy, place it on a wire rack over a baking sheet and bake at 350 degrees Fahrenheit for about 8 to 10 minutes until it’s warmed through. This method keeps the bottom from getting soggy.

FAQs

Can I use frozen fish fillets? Yes, but thaw them completely and pat them dry before marinating. Excess moisture will prevent crisping.

What if I can’t find gochugaru? Gochugaru is worth tracking down, but if you absolutely can’t, you can substitute with paprika mixed with a tiny pinch of cayenne pepper. It won’t be quite the same, but it’ll work in a pinch.

Can I make this with other types of fish? Absolutely. Any white fish works beautifully. I’ve done this with halibut, flounder, and even sea bass when I’m feeling fancy.

Is this spicy? Gochugaru adds gentle heat, not intense spice. If you’re sensitive to heat, start with 2 tablespoons of gochugaru instead of 3, then add more next time if you want it spicier.
