Follow these simple, step-by-step instructions to achieve perfectly flaky, moist, and flavorful baked salmon every single time. The process is straightforward and designed for a foolproof result.

Step 1: Prepare Your Oven and Baking Dish
First things first, preheat your oven to 400°F (200°C). Position a rack in the center of the oven to ensure even cooking. While the oven is heating up, prepare your baking dish or a rimmed baking sheet by lining it with parchment paper. This is a crucial step for easy cleanup and prevents the salmon from sticking.

Step 2: Pat the Salmon Dry
Remove the salmon fillet from its packaging and place it on a clean plate or cutting board. Using paper towels, gently pat the entire surface of the salmon dry. This includes the skin side if you are using a skin-on fillet. Removing excess moisture from the surface is key to helping the top of the salmon get a lovely, slightly roasted texture rather than just steaming in the oven.

Step 3: Create the Lemon Herb Marinade
In a small bowl, combine the extra virgin olive oil, the zest of the entire lemon, the juice of half the lemon, the minced garlic, chopped fresh dill, chopped fresh parsley, sea salt, and freshly ground black pepper. Whisk these ingredients together until they are well combined into a thick, fragrant paste. The aroma at this stage is a wonderful preview of the delicious meal to come.

Step 4: Season the Salmon
Place the dry salmon fillet onto your prepared parchment-lined baking sheet. Using your hands or a spoon, spread the lemon herb mixture evenly all over the top and sides of the salmon. Be generous and ensure every part of the fillet is coated in the flavorful marinade. This coating will not only season the fish but also create a protective barrier that locks in moisture during baking.

Step 5: Garnish with Lemon Slices
Take the remaining half of the lemon and slice it into thin rounds. Arrange these lemon slices in a single layer over the top of the herb-coated salmon fillet. As the salmon bakes, these slices will release their juice and essential oils, infusing the fish with even more bright, citrusy flavor and creating a beautiful presentation.

Step 6: Bake to Perfection
Place the baking sheet in the preheated oven. Bake for 12-18 minutes. The exact baking time will depend on the thickness of your salmon fillet. A good rule of thumb is to bake for approximately 6-8 minutes per inch of thickness. The salmon is done when it is opaque and flakes easily when gently pressed with a fork. Be very careful not to overcook it, as this can result in dry fish. If you have an instant-read thermometer, the internal temperature should reach 135-140°F (57-60°C) in the thickest part for a perfectly cooked, moist result.

Step 7: Rest and Serve
Once the salmon is cooked, carefully remove the baking sheet from the oven. Let the salmon rest on the pan for 3-5 minutes before serving. This brief resting period allows the juices to redistribute throughout the fillet, ensuring every bite is moist and tender. Serve immediately, garnished with a little extra fresh dill or parsley if desired.
