Classic Baked Salmon

Why This Classic Baked Salmon Works

The main thing that makes this salmon turn out well is the foil packet. Once the foil is sealed, the heat from the oven turns the liquid from the olive oil, lemon, and the salmon’s own juices into steam. That steam stays trapped around the fish, so the salmon cooks gently instead of drying out. The fish cooks through, but it still stays moist and flakes easily with a fork.

While it bakes, the garlic, dill, and lemon slices sit right on top of the salmon. As they heat up, their juices and oils sink down into the fish instead of escaping into the pan. The olive oil on the surface helps those flavors spread over the whole piece and also keeps the top from getting tough. Baking at 400°F is hot enough to cook the salmon in about 15–20 minutes, but not so hot that the outside overcooks before the center is done. When the foil is opened at the end, the steam escapes instead of soaking the fish, so the salmon stays tender, not soggy.

Mistakes To Avoid

Letting the salmon bake too long is the fastest way to ruin this dish. In the oven, the fish keeps losing moisture, so the flesh turns stiff and chalky instead of soft and flaky, and the white albumin pushes out in thick clumps on the surface.

Leaving the foil packet open or loosely sealed causes the steam to escape. Without that trapped moisture, the top of the salmon dries out before the center is fully cooked, so the fish ends up tough on the edges and uneven inside.

Placing the salmon straight from the fridge into the oven often leads to uneven cooking. The outside hits temperature first and tightens up, while the middle lags behind and can stay a bit raw or mushy when the edges are already starting to dry.

Letting the lemon slices cover the fish in a thick, solid layer can create soggy spots. Under those slices, the surface steams instead of roasting, so parts of the salmon turn wet and pale while other areas cook normally.
