If you think salmon is dry, it’s because it’s been cooked too long. This Baked Salmon Temperature Guide will show you how to always cook soft, juicy salmon.
Overcooked salmon is a chore. It’s dry, chewy, and will make you want to swear off fish.
These tips will help you find the right internal temperature for salmon and give you an idea of how long it will take to bake at different oven temperatures for both a whole side of salmon and individual pieces (fillets).
As a salmon lover I’m always trying to find the best way to cook this delicious and healthy fish. Lately I’ve been wondering – is 400 degrees too hot for salmon? This higher oven temperature promises speedier cooking times, but could it dry out my fillets or impart off flavors?
I decided to do some experimenting in my kitchen to find the definitive answer on baking salmon at 400 degrees. Read on for my complete guide to temperature, timing, and techniques for perfectly cooked salmon every time.
The Benefits of 400 Degrees for Salmon
Cooking salmon in a 400 degree Fahrenheit oven offers a few advantages:
-
Quick cooking. The high heat roasts the salmon fast. Fillets that are thinner may only need 8 to 10 minutes, but cuts that are thicker will need 12 to 15 minutes.
-
Browning. 400 degrees promotes more surface browning through the Maillard reaction. This adds deeper flavor and appealing texture.
-
Convenience. It’s possible to roast salmon and cook vegetables or side dishes at the same time in a 400~ oven.
So 400 degrees F can be good for salmon, as long as you know how to handle the fillets so they don’t get too done. Let’s look at some tips.
Prevent Salmon from Drying Out
Salmon contains delicate, highly unsaturated omega-3 fatty acids. These healthy fats are a big contributor to salmon’s succulent texture.
Unfortunately, these fats also make salmon prone to moisture loss and oxidation at high temperatures. Too much time in a 400 F oven can damage these valuable nutrients and leave your salmon parched.
Here are some ways to keep salmon moist when baking at 400 degrees:
-
Brine it. A quick brine in saltwater plumps up the salmon fillets and seasons them throughout.
-
Wrap in foil. Sealing salmon in foil packets helps retain moisture as it steams inside.
-
Add fat. Topping salmon with olive oil, butter, or mayo gives added fat to combat dryness.
-
Go thick. Choose a nice 1 1/2-2 inch thick salmon fillet for the best results in a hot oven.
-
Cook until just opaque. For tender, flaky salmon, bake until it’s just opaque but still glistening inside.
With the right precautions, you can achieve tender, buttery baked salmon even at 400 F. Keep reading for more tips.
How Long to Bake Salmon at 400 Degrees
Salmon fillet thickness is key when determining bake time. Here are general guidelines based on thickness:
- 1 inch thick: Bake for 10-12 minutes
- 1 1/2 inches thick: Bake for 12-14 minutes
- 2 inches thick: Bake for 14-16 minutes
These times are for wild salmon fillets about 6-8 ounces each. Farm-raised salmon may need a minute or two longer due to higher fat content.
No matter what, use an instant-read thermometer to check for doneness instead of relying solely on time. And always err on the side of slightly undercooked when working with quick-cooking 400 degree heat.
Checking Salmon Temperature
An instant-read thermometer takes the guesswork out of determining doneness. Check the thickest part of your salmon fillet. Temperatures for varying levels of doneness are:
- 125°F = Rare
- 130-135°F = Medium rare
- 140°F = Medium
- 145°F = Well done
For tender, moist salmon, I recommend removing fillets from the 400 degree oven when they reach 135°F. The temperature will rise a bit more as they rest.
If you don’t have a thermometer, use the “nick and peek” method. Make a little cut into the thickest section of salmon and check that the interior is just opaque with a hint of pinkness.
Use both visual and temperature cues for perfect results.
Resting Salmon After Baking
A quick 5 minute resting period after baking is essential. As salmon rests, the proteins relax and reabsorb any juices expelled during cooking.
I like to tent foil loosely over the fillets to allow steam to escape while keeping them warm. Resting makes salmon more tender and moist. Don’t skip this step, especially after high-heat roasting.
Adding Flavor at 400 Degrees
High oven temperatures can intensify flavors since the sugars and compounds caramelize quicker. Here are some easy ways to add flavor when baking salmon at 400 degrees:
-
Coat with olive oil, salt, pepper, and fresh herbs or citrus zest.
-
Brush with glazes like teriyaki, soy sauce, honey, or mustard toward the end of baking.
-
Top with pesto, harissa, chili oil, or spice rubs before cooking.
-
Stuff salmon with lemon and herbs before baking for built-in moisture and flavor.
-
Pair with sauces like chimichurri, salsa verde, or lemon dill sauce.
With a few simple additions, you can take basic 400 degree baked salmon to new flavor heights.
Step-By-Step Method
Follow these simple steps for foolproof baked salmon at 400 degrees:
-
Heat oven to 400°F. Line a baking sheet with parchment paper or foil.
-
Pat salmon dry and brush both sides with oil. Season generously with salt and pepper.
-
Arrange fillets on the baking sheet. Sprinkle with herbs or citrus zest if desired.
-
Roast for 10-16 minutes depending on thickness. Check temperature regularly.
-
When salmon reaches 135°F, remove from oven and let rest for 5 minutes.
-
Serve salmon warm with glazes, sauces, or garnishes as desired!
The Best Cuts of Salmon for Roasting
When cooking salmon in a hot 400 degree oven, look for good thick fillets to prevent overcooking:
-
King salmon offers the best fat content and richest flavor for roasting. Aim for 1 1/2 pound fillets about 2 inches thick.
-
Coho and Sockeye also hold up well to high heat. Look for center-cut fillets around 6-8 ounces each.
-
Atlantic salmon is budget-friendly but lower in omega-3s than wild Pacific varieties. Get thicker 2-inch fillets for roasting.
-
Smaller salmon like keta or pink salmon are better suited to gentler cooking. They can dry out at 400 degrees.
Stick with heftier wild-caught salmon cuts and you’ll get delicious results from the 400 degree oven every time.
Should You Roast Salmon at 400 Degrees?
I tested multiple batches of salmon baked at both 400°F and 375°F. The 400 degree salmon emerged juicier with nice caramelized bits when I followed a few guidelines:
✔️ Brined fillets for 30 minutes
✔️ Used at least 1 1/2 inch thick wild king or sockeye fillets
✔️ Monitored temperature closely
✔️ Rested salmon before serving
So yes, baking salmon at 400 degrees F can produce exceptional results with a few smart precautions. You’ll get tender, flaky texture with that coveted crusty top.
For thinner or delicate fillets, try a more moderate 350-375°F oven and cook a minute or two longer. But with prime salmon cuts and the right techniques, 400 degrees is a fine choice for roasting incredible salmon fast.
Salmon Temperatures by Doneness
Another way to think about salmon temperature is by rare, medium-rare, medium, and well-done. My preference is medium/medium-rare.
Remove the salmon from the heat at each of the below temperature ranges, according to your preference.
- Rare Salmon. Less than 120 degrees F.
- Medium-Rare Salmon. 125 degrees F to 130 degrees F.
- Medium Salmon. 135 degrees F to 140 degrees F (the sweet spot!).
- Well-Done Salmon. 145 degrees F or more (please don’t do this).
More Frequently Asked Questions
Pacific salmon that was caught in the wild is the best kind to buy because it has the fewest calories and most nutrients. Look for king, coho, sockeye, pink, or chum salmon.
If your salmon has gone bad it will smell slightly sour and fishy. Fleshy, mushy flesh and spots (gray spots, dark spots, or milk-like reside) are other signs that your salmon has gone bad.
Don’t panic if you see a white liquid coming from your salmon. This is a protein called albumin that can escape from the salmon when it’s cooked. It is harmless and safe to eat.
Some types of king salmon have flesh that is lighter, almost white, instead of the usual orange, pink, or reddish color. This type of king salmon is beloved for its melt-in-your-mouth texture, so enjoy this rare find!.
The gray stuff on the bottom of salmon is fat. It tastes like the rest of the salmon fillet, is safe to eat, and is full of omega-3 fatty acids. If you prefer to remove it, you can simply scrape it off before serving.
You can choose whether to leave the skin on or not as long as the recipe doesn’t say so. Leaving the skin on provides a barrier between the heat and your fish, giving slight protection from overcooking. You can easily remove it once you’re done cooking. But you can cook the salmon without the skin on if you don’t want to deal with taking it off afterward or if you want to show it off without the skin on.
You don’t have to cover the salmon unless your recipe says to (for example, if you are using the foil packet method).
