Crispy fish skin is one of the best parts of cooking fish. The texture and flavor it adds really takes a simple fish fillet to the next level. While pan frying is the most common way to achieve crispy fish skin, the oven can also be used with great results.
Why Bother Crisping Fish Skin in the Oven?
There are a few key benefits to using the oven instead of pan frying:
- It’s hands off – once the fish goes in the oven, you don’t have to monitor it as closely as on the stovetop.
- More even cooking – the hot air circulates all around the fish, crisping the skin on top and bottom.
- Healthier – pan frying often requires a good amount of oil or butter to crisp the skin. The oven allows you to use less added fat.
- Easy cleanup – unlike dirtying multiple pans on the stove, the oven contains the mess to one sheet pan.
While pan frying may be a tad quicker, the oven approach still only takes about 15-20 minutes for thin fish fillets. The hands off cooking and easier cleanup make it worth the small amount of additional time.
Choosing the Right Fish for Oven Crisping
You can crisp the skin of most white fleshed fish in the oven. The best candidates are fish with thin, delicate skin that will become crispy and edible when cooked. Some top choices include:
Fattier fish like salmon and trout can also work, but their thicker skin may come out more leathery than crispy. Still worth trying though!
Thicker fish steaks or fillets may require a higher oven temperature and/or broiling at the end to fully crisp the exterior. Follow the recommendations in your specific recipe.
Prepping Fish Fillets for Crispy Skin
Proper prep is key for getting the skin ultra crispy in the oven. Here are some tips:
- Start with a nonstick pan or line a sheet pan with parchment paper – the fish needs to release cleanly after cooking.
- Pat the fish fillets very dry with paper towels. Any moisture will steam the skin rather than crisping it.
- Don’t season the skin until just before cooking. Salt and spices can draw out moisture.
- Brush the skin very lightly with oil. Too much will make it soggy.
- Optionally, you can score the skin diagonally across the fillet. This allows the fat to render and moisture to escape.
How to Cook Fish Fillets for Crispy Skin
Once your fish fillets are properly prepped, it’s time to pop them in the oven. Use these oven crisping techniques for perfect results:
- Heat the oven to 400°F-450°F. The high heat helps the skin crisp up quickly before the fish overcooks. For thinner fillets, you can go up to 500°F.
- Place prepared fish fillets skin side down on the oiled or parchment-lined pan. Leave space between fillets.
- Season the skin lightly with salt and any other desired spices or herbs. Go easy on wetter ingredients like lemon or butter which can make the skin soggy.
- Roast for 8-12 minutes until the skin looks bubbly and golden brown. The flesh should flake when poked with a fork. Cook time depends on thickness.
- Optionally, switch the oven to broil for the last 1-2 minutes if you want the skin extra crispy. Watch closely to avoid burning.
- Remove the fish from the oven and let it rest for 2-3 minutes before serving. The skin will continue to crisp as it cools.
- Use a thin spatula to gently transfer the fish from the pan to plates or a serving platter. Be careful not to tear the delicate crispy skin!
Troubleshooting Crispy Fish Skin in the Oven
Follow these tips if your oven-cooked fish skin isn’t getting crispy:
- Dry the fillets thoroughly and don’t brush with too much oil – moisture is the enemy of crispy.
- Cook at a higher oven temp up to 500°F.
- Broil the fish for 60-90 seconds at the end to finish crisping the skin.
- Cook the fish closer to the top of the oven where the air is hottest.
- Use a convection setting if your oven has it to circulate the hot air.
- Try a longer bake time, checking frequently to avoid overcooking.
