How Long to Cook Salmon: A Practical Time Guide
Learn how long to cook salmon with precise timing by thickness and method. This guide covers baking, pan-searing, broiling, grilling, and poaching, plus thermometer guidance and common mistakes.
Cooking salmon precisely depends on thickness and method. A 1-inch fillet typically bakes at 400°F (204°C) for 10–12 minutes, while pan-searing takes about 4–6 minutes per side. Use a thermometer: 125°F (52°C) for medium-rare, 135–145°F (57–63°C) for fully cooked.
What 'how long to cook salmon' means for home cooks
When you search for the timing of salmon, you’re really looking at two variables: the thickness of the fillet and the heat method you choose. The goal is a moist, flaky texture without drying out the fish or leaving it undercooked. According to Cooking Tips, the most reliable way to hit the right doneness is to combine thickness-aware time estimates with thermometer guidance. Start with a predictable starting point, then adjust by a minute or two based on thickness and oven or pan performance. This approach helps you avoid the common pitfall of guessing based on color alone, which can be misleading as salmon cooks from the outside in and carries carryover heat once removed from heat.
How temperature and doneness relate to time
Doneness is closely tied to internal temperature rather than a single clock time. Salmon cooks quickly, and even a small variance in oven heat or pan temperature can shift results. By aiming for a specific internal temperature, you maintain moisture and texture. The target range is commonly discussed as 125°F for a glistening, medium-rare center, and 135–145°F for more traditional, fully cooked fish. Remember that thick fillets will take longer than thin slices, and bone-in portions will cook differently than boneless fillets. A reliable thermometer becomes your most valuable tool.
Thickness matters: turning minutes into doneness
Simple rule of thumb: add about 2–3 minutes of total cooking time per ½ inch of thickness when using dry-heat methods (baking, frying, broiling). For example, a 1-inch fillet will fall within a modest 10–12 minute baking window, while a 2-inch cut may require 16–20 minutes. If you’re pan-searing, the rule shifts to roughly 4–6 minutes per side for a 1-inch fillet and longer for thicker cuts. The exact time depends on your oven, pan heat, and whether the fillet starts cold or at room temperature. Always verify with a thermometer for consistency across meals.
Quick-reference times by method (overview)
- Baking: 10–12 minutes per 1-inch thickness at 400°F (204°C); add a few minutes for thicker fillets.
- Pan-searing: 4–6 minutes per side for 1-inch; adjust to 6–8 minutes per side for thicker cuts.
- Broiling: 6–8 minutes total, watching closely to avoid browning too fast.
- Grilling: 5–7 minutes per side for 1-inch fillets; move to indirect heat for thicker portions.
- Poaching: 8–12 minutes depending on thickness and simmering temperature.
How to use a thermometer for precision
Insert the thermometer into the thickest part of the fillet, avoiding bone if present. Remove from heat when the thermometer reads 125°F for a juicy, medium-rare center, or 135–145°F for a more traditional, fully cooked finish. Because carryover heat continues to cook the fish after removal, plan to pull the salmon slightly before reaching the target if you want a specific final temperature. This technique reduces the risk of dry, overcooked edges.
Resting and serving for best texture
Let cooked salmon rest for 2–5 minutes before serving. Resting lets juices redistribute, preserving moisture and giving a cleaner slice. Serve with a light squeeze of lemon, a dab of herb butter, or a simple vinaigrette to accent flavor without overpowering the fish’s delicate profile.
Tools & Materials
- Instant-read thermometer(Probe into thickest part; avoid bone.)
- Baking sheet or rimmed pan(Line with parchment for easy cleanup.)
- Aluminum foil or parchment(Helpful for easy cleanup when baking.)
- Skillet (cast iron or stainless)(For pan-searing; ensure it's hot before adding fish.)
- High-heat cooking oil(Neutral oil like canola, avocado, or grapeseed.)
- Paper towels(Pat dry to improve browning.)
- Tongs or spatula(Gentle tools to flip without breaking fillet.)
- Oven mitts(Safety before handling hot pans.)
Steps
Estimated time: Total time varies by method and thickness: approximately 15–25 minutes for most home cooks.
- 1
Gather and pat dry the salmon
Place the fillet on a clean surface and pat dry with paper towels to remove surface moisture. This helps achieve better browning and even cooking.
Tip: Dry surface moisture = crisper exterior. - 2
Season the fillet
Season evenly with salt and pepper, or your favorite dry rub. Mild seasoning helps highlight the fish without overpowering its natural flavor.
Tip: Season at least 5 minutes before cooking for better flavor absorption. - 3
Preheat the cooking surface
Preheat the oven to 400°F (204°C) or heat a skillet over medium-high with a thin layer of oil. Proper heat ensures quick, even cooking and browning.
Tip: A hot pan or oven prevents sticking and promotes crust formation. - 4
Cook the salmon
Place the salmon on the preheated surface and cook according to your chosen method. Time depends on thickness; aim for 10–12 minutes in the oven per 1 inch, or 4–6 minutes per side in a hot skillet.
Tip: Do not flip too early; let the skin release naturally if skin-on. - 5
Check doneness with a thermometer
Insert the thermometer into the thickest part. Remove when it reads 125°F for medium-rare or 135–145°F for fully cooked.
Tip: Remember carryover heat; pull a hair early if you want a specific final temp. - 6
Rest and serve
Let salmon rest 2–5 minutes before serving to retain moisture. Slice gently and serve immediately for best texture.
Tip: A squeeze of lemon brightens flavor without dulling the fish.
Quick Answers
What is the safe internal temperature for salmon?
The USDA recommends cooking salmon to 145°F (63°C). However, many home cooks prefer 125–135°F for a moister, medium-rare center. If serving vulnerable populations, follow the higher end of the range.
Salmon should reach at least 145 degrees Fahrenheit for safety, though some people enjoy it moister at 125 to 135 degrees. Use a thermometer to decide your preferred doneness.
Should I thaw salmon before cooking it?
Yes. Thaw in the refrigerator overnight for best texture, or use a quick cold-water method if you’re short on time. You can cook some salmon from frozen, but expect longer cooking times and looser texture.
Yes, thawing is best for even cooking. If you’re in a hurry, you can cook from frozen with extra time, but texture may be less uniform.
Is skin-on salmon better for cooking time and flavor?
Cooking with skin on helps protect the flesh and yields a crispier finish when seared or roasted. Flip carefully to avoid tearing the skin.
Skin-on salmon can stay juicier and browns nicely when cooked properly; flip gently to keep the skin intact.
Can I cook salmon using multiple methods in one dish?
Yes. A common approach is to start with a pan-sear for color, finish in the oven to finish cooking evenly. This balances crust with interior doneness.
You can sear first for color, then finish in the oven to ensure even cooking.
How can I tell if salmon is done without a thermometer?
Look for opaque flesh that flakes easily with gentle pressure. Avoid opaque, dry edges; if in doubt, use a thermometer.
If it flakes and looks opaque all the way through, it’s usually done. But a thermometer is more reliable.
