How to crisp skin on fish fillets under the broiler or in a hot pan
Crisping fish skin gives you a satisfying contrast between a crunchy exterior and tender flesh. Whether you use the broiler or a hot pan, the key is dry skin, high heat, and quick, confident handling. This guide walks you step-by-step so you end up with golden, crackly skin every time.
Step 1: Select and portion fillets
Choose skin-on fillets about 3/4–1 inch thick for even cooking; 6–8 ounce portions work well. Thinner pieces cook too fast and thicker ones risk overcooking the interior before the skin crisps. Pat fish dry and remove any loose scales with the edge of a knife.

Step 2: Score or leave whole
If the fillet has very thick skin, make 2–3 shallow 1/8-inch diagonal cuts through the skin only to prevent curling. For most fillets leave them whole; scoring is optional and helps maintain contact with the pan or rack. Space cuts about 1 inch apart and avoid cutting into the flesh.

Step 3: Salt and season just before cooking
Season skin side generously with 1/4–1/2 teaspoon kosher salt per fillet and a light sprinkle of pepper; season flesh side lightly as well. Salting too far ahead can draw out moisture, so apply 5–10 minutes before cooking for better crisping. Add a dusting of 1/2 teaspoon cornstarch for extra dryness on oily fish if desired.

Step 4: Preheat pan or broiler properly
For pan: heat a heavy skillet (cast iron or stainless) over medium-high to high heat until a few drops of water sizzle and evaporate (about 3–4 minutes). For broiler: position rack 4–6 inches from the element and preheat high broil for 5–10 minutes. High heat is essential to render fat and crisp skin quickly.

Step 5: Use the right fat and amount
Add 1–2 tablespoons neutral oil with a smoke point above 400°F (canola, grapeseed) to the pan and swirl to coat; for broiler use a thin brush of oil on the skin. Use just enough to coat—too much causes splatter, too little leads to sticking. If you want extra flavor, add 1 tablespoon butter in the last 30 seconds for pan-finished gloss.

Step 6: Cook skin-side down first
Pan method: place fillets skin-side down and press gently with a spatula for 10–15 seconds to prevent curling; cook 3–5 minutes without moving until skin is deeply browned. Broiler method: place fillets on a lightly oiled broiler pan skin-side up 5–7 minutes until edges brown, then flip for 30–60 seconds if flesh needs finishing. Leave flesh-side contact minimal when crisping skin first.

Step 7: Finish to desired doneness
After skin crisps, flip fillets and cook flesh-side 30–90 seconds for medium-rare to medium (internal 120–130°F), or 1–2 minutes for well-done (internal 135–145°F), depending on thickness. Rest for 3–5 minutes to let juices redistribute before serving. The skin will stay crisper if served immediately rather than sitting in sauce.

- Work with cold, refrigerated fillets so flesh stays firm during high heat cooking.
- Keep a splatter screen and long spatula handy when pan-cooking to reduce mess and flipping risk.
- Dry brining for 20 minutes (light salt) can improve texture but avoid longer than 30 minutes to prevent excess moisture loss.
- If skin begins to burn, lower heat, tilt pan to reduce oil contact, or move under the broiler for a short blast instead.
- Use a thin metal spatula to slide smoothly under skin; angling it helps lift without tearing.
- For seafood with thick fat like salmon, render more fat by pressing firmly for the first 20–30 seconds in the pan.
- Never overcrowd the pan or broiler tray; overcrowding lowers surface temperature and prevents crisping.
- Be careful with high heat—hot oil can splatter; keep face and hands back when flipping and use protective oven mitts.
- Do not flip or poke the fillet repeatedly; frequent movement prevents a proper crust from forming and can tear the skin.
