Herb and Citrus Foil Baked Salmon

Why This Herb and Citrus Foil Baked Salmon Works

In the oven, the foil packets trap steam from the lemon, orange, and salmon. That steam surrounds the fish and keeps it moist instead of drying out. Because the packets are sealed, the juices from the salmon stay close to the fish instead of running off onto a pan. The heat moves gently through the foil, so the salmon cooks evenly from all sides and flakes instead of turning tough.

As the packets heat up, the citrus slices soften and give off their juice. That juice mixes with the olive oil and the salmon’s own fat, so the fish sits in a small pool of hot, flavored liquid while it cooks. Rosemary, thyme, garlic, and dill sit right on the fish, so their taste slowly soaks into the surface as it bakes.

By the time the packets are opened, the salmon is cooked through but still tender, the citrus is soft, and there is a light, hot sauce in the bottom of each packet ready for serving.

Mistakes To Avoid

Letting the salmon bake too long in the sealed foil packets can quickly dry it out. The trapped steam keeps cooking the fish even after it looks done, so the flesh turns firm and chalky instead of moist and flaky.

Leaving gaps or loose folds in the foil means steam escapes during baking. Without that trapped moisture, the citrus slices can dry out and scorch at the edges, and the salmon cooks unevenly, with some spots still soft and others tough.

Cutting the citrus slices too thick makes a heavy, wet layer on top of the fish. The thick slices release a lot of juice, which can water down the surface of the salmon so it steams in a puddle and turns a bit mushy instead of gently firm.

Placing very cold salmon straight from the fridge into the oven often leads to uneven cooking. The outside reaches the right texture while the center stays slightly translucent and soft, so by the time the middle is done, the thinner edges are already overcooked.
