How Long To Bake Fish?

How long do you bake fish by type?

The 10-minute-per-inch rule at 400°F (205°C) is the foundation. Salmon (1-inch fillets): 12-15 minutes; thicker pieces 15-20 minutes. Cod (1-inch fillets): 10-12 minutes; thick pieces 15-20 minutes. Tilapia (typically 1/2-3/4 inch): 10-12 minutes. Halibut (1-inch steaks): 12-15 minutes; thicker 15-20 minutes. Mahi-mahi (1-inch fillets): 10-15 minutes. Trout (whole or fillets): 12-18 minutes. Snapper (1-inch fillets): 12-15 minutes. Sea bass (1-inch): 12-15 minutes. Tuna (1-inch steaks): 8-12 minutes (often served medium-rare). Swordfish (1-inch steaks): 8-12 minutes. Catfish (3/4-inch fillets): 12-15 minutes. Whole fish (1-2 lbs): 20-30 minutes. Mackerel (1-inch fillets): 12-15 minutes. Sardines (small whole fish): 8-12 minutes. The 145°F (63°C) internal temperature is the USDA target for most fish; salmon can go lower (125-130°F preferred). Tuna can serve rare. Most fish dry out past 150°F internal.

How do you bake fish properly?

Universal technique applies to most fish. Step 1: preheat oven to 400°F (205°C). Step 2: pat fish completely dry with paper towels (essential for browning - wet fish steams). Step 3: remove pin bones if present using tweezers. Step 4: brush fish with olive oil or melted butter; season simply with salt, pepper, and herbs (don't overpower delicate fish). Step 5: place fish on parchment-lined baking sheet; for skinless fillets, baking dish helps; foil packets steam fish for tender results. Step 6: bake for 10 minutes per inch of thickness (the rule); check earlier for thin fillets. Step 7: optional toppings before baking: lemon slices on top; herb butter; garlic and rosemary; pesto; everything bagel seasoning. Step 8: check doneness with flake test or thermometer; remove at 140°F internal. Step 9: let rest 2-3 minutes before serving. Don't overcrowd the baking sheet - fish needs space to brown rather than steam.

How do you know when fish is done?

Multiple cues confirm doneness. Internal temperature: 145°F (63°C) is USDA target for most fish; salmon often preferred at 125-130°F; tuna can serve rare at 110-115°F. Flake test (universal for fish): gently press with a fork; fish should flake apart easily into clean, opaque pieces; if it resists, cook 1-2 more minutes; if it crumbles into dry chunks, it's overcooked. Color check: properly cooked fish is uniformly opaque (white for white fish; pink for salmon); gray, translucent, or raw-looking areas mean undercooked. Texture: fish should be tender but hold its shape; falling apart means overcooked; rubbery means overcooked. Don't overcook - fish dries quickly; the difference between perfect and dry is just 1-2 minutes. The sweet spot for most white fish: just barely flaking with the surface looking matte. For salmon: just barely opaque in center with slight translucency. Each fish has its own ideal doneness - learn what each looks like.

Tips for perfectly baked fish?

Universal principles apply to all fish. Use the 10-minute-per-inch rule: simple and reliable. Pat very dry: essential for browning. Don't overcook: this is the universal fish-cooking mistake. Use a thermometer for accuracy: especially for thick fish. Season simply: good fish doesn't need much. Match the flavor to the fish: bold seasonings for mild fish (tilapia, cod); subtle for richer fish (salmon, mackerel).
