Maple Mustard Baked Salmon

Why This Maple Mustard Baked Salmon Works

In the oven, the maple syrup and mustard warm up and start to thicken on the surface of the salmon. That sticky glaze coats the fish and keeps a lot of the moisture from escaping, so the salmon stays juicy instead of drying out. As the heat moves through the fillet, the salmon slowly firms up and the big flakes start to separate, which is why it breaks apart so easily with a fork when it is done.

While it bakes, the olive oil mixes with the maple and mustard and spreads over the top of the fish, so the heat doesn’t hit any one spot too hard. Lemon slices on top slowly release their juice as they soften, so a little bit of that sour liquid sinks into the glaze instead of just sitting on the plate. By the time it comes out of the oven, the outside has a slightly sticky, shiny coating and the inside stays tender, with the dill added at the end so it doesn’t wilt in the heat.

Mistakes To Avoid

Letting the salmon bake too long dries it out fast. The glaze starts to bubble and tighten, the edges turn dark and sticky, and the fish goes from moist and flaky to firm and almost chalky in the center.

Setting the oven hotter than 375°F makes the outside cook much faster than the inside. The maple in the glaze burns in spots, turning bitter and hard, while the thickest part of the salmon can still look a bit raw and glossy.

Pouring all the glaze on in one thick layer at the start causes it to slide off and pool around the fish. The sauce in the pan can scorch and turn into a hard, burnt ring, while the top of the salmon ends up with only a thin, patchy coating.

Using very thin or tail-end pieces of salmon together with thick center cuts leads to uneven cooking. The thin parts overbake and turn stringy by the time the thicker section in the middle finally flakes.
