A thick salmon usually takes longer to cook while a thin one needs less time. The number of fillets to be cooked also influences the time required.

Why Does Salmon Explode in the Microwave?

Salmon explodes in the microwave because it is a fatty fish. When microwaving, the fat heats up and comes into contact with moisture in the fish.

The water evaporates and expands in the microwave causing an explosion.

To avoid such explosions it is advisable to pat the salmon fillet dry using a paper towel. This removes any ice crystals and moisture content from the fish.

Laying a piece of parchment paper or paper towel over the fish while microwaving could also do the trick.
