Why Baking is the Best Way to Cook Salmon

Salmon is an oily fish, which is precisely what makes it so well-suited for the dry, even heat of an oven. Unlike leaner fish that can dry out quickly, the natural fats in salmon act as an internal baste, keeping the flesh incredibly moist and tender as it cooks. Baking at a moderately high temperature allows the outside to roast beautifully while the inside gently cooks to a perfect, flaky finish. It’s a forgiving, hands-off technique that consistently yields delicious results.

The Core Ingredients for Perfect Baked Salmon

The beauty of this method is its simplicity. You only need a few high-quality ingredients to make the salmon shine.

Salmon Fillets: Look for fillets that are about 1 to 1.5 inches thick. You can use skin-on or skinless, though skin-on helps protect the fish from overcooking and can get wonderfully crisp.
Olive Oil: A good-quality olive oil adds flavor and helps the salmon brown.
Salt and Pepper: For seasoning the fish.
Lemon and Fresh Herbs: Sliced lemon, fresh dill, or parsley are classic pairings that brighten the rich flavor of the salmon.

Preheat and Prep: Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper for easy cleanup.
Prepare the Salmon: Take the salmon out of the refrigerator about 20 minutes before cooking to let it come closer to room temperature. Pat the fillets completely dry with a paper towel. This is a critical step for achieving a nice roast rather than just steaming the fish.
Season Generously: Place the salmon on the prepared baking sheet. Drizzle with olive oil and use your hands to rub it evenly over the fillets. Season generously with salt and pepper.
Add Aromatics: Top each fillet with a few slices of fresh lemon and some sprigs of dill or parsley.
Bake to Perfection: Place the baking sheet in the preheated oven and bake for 12-15 minutes. The exact time will depend on the thickness of your fillets. The best way to check for doneness is with the “fork test” or a thermometer (more on that below).
Rest and Serve: Remove the salmon from the oven and let it rest for a few minutes before serving. This allows the juices to redistribute throughout the fillet.

The Science Behind Perfectly Cooked Salmon (Our Pro-Tips)

Understanding the why behind the steps is what elevates your cooking from following a recipe to truly mastering a technique.

The Ideal Temperature

For the most succulent texture, salmon should be cooked to an internal temperature of 125°F to 130°F (52°C to 55°C) in the thickest part. At this temperature, the proteins are cooked, but they haven’t seized up and squeezed out all the moisture. An instant-read thermometer is the most reliable tool for this.

What is That White Stuff?

If you’ve ever seen a white, protein-like substance ooze out of your salmon, you’ve seen albumin. This is a harmless protein that gets pushed out of the muscle fibers when the fish is cooked too aggressively or for too long. Baking at a higher temperature, like 400°F, helps cook the fish quickly, minimizing the amount of albumin that appears.

Don’t Overcrowd the Pan

Always leave space between your fillets on the baking sheet. Packing them too tightly will cause them to steam instead of roast, preventing them from browning nicely.

How to Bake Salmon From Frozen

Forgot to thaw your fish? No problem. Baking is one of the best ways to cook salmon directly from frozen.

Preheat your oven to 425°F (220°C).
Rinse the frozen fillets under cold water to remove any ice glaze and pat them dry.
Place on a parchment-lined baking sheet, brush with oil, and season.
Bake for approximately 25-30 minutes. Because the fish is cooking for longer, it’s a great idea to use a sauce (like a lemon-butter or pesto) to help keep it moist.

Frequently Asked Questions (FAQ)

How long do you bake salmon at 400°F?

A good rule of thumb is to bake for 4-6 minutes per half-inch of thickness. For a standard 1-inch thick fillet, this is typically 12-15 minutes.

How can you tell when baked salmon is done without a thermometer?

Gently press a fork into the thickest part of the fillet. If the fish flakes apart easily, it’s done. The color should also have changed from translucent deep pink to a more opaque, lighter pink.

Should I bake salmon covered or uncovered with foil?

For this method, bake it uncovered. Roasting uncovered allows the dry heat of the oven to create a beautifully browned exterior. Covering it would trap steam, resulting in a poached texture.

Serving and Storing

Serve your perfectly baked salmon with roasted asparagus, a fresh green salad, or fluffy quinoa. Leftovers are fantastic and can be stored in an airtight container in the refrigerator for up to 2 days. Flake the cold salmon over a salad for lunch the next day or mix it with a little mayo and herbs for a quick salmon salad.
