salmon + microwave = BLAM, any suggestions?

You can simulate steaming in a microwave. First defrost the salmon. Put it in a glass dish. Put some soy sauce on the bottom of the dish, say half a cm deep. Add some chopped ginger. Cover the dish with plastic wrap. Microwave for 5 minutes or so. Tastes great and healthly too.

Yeah. Don't use the microwave. Yes, the tool is useful for certain things--defrosting, reheating, or indeed making french fries (per a lovely blog). It is categorically not useful for cooking from raw. Use a pan, your oven, or a grill.

My suggestion would be to cook en papillote, (wrapped in partchment) such as in this recipe. There is no shame using a microwave for serious culinary endeavors as long as you don't ask it to do what it can't do.

I would try reducing the cooking time. I was having this problem with Tallapia and found that reducing the cook time from 4min to about 2:30 fixed the problem. It comes out great!

I had the same issue until I cut the the power down to half normal. And it only takes about 3-4 minutes for a filet of fish.

I assume you mean salmon in 4-6 ounce fillet pieces. Boiling fish juices and bubbling fat makes salmon explode. Jab some holes in the salmon with the tip of a sharp knife before you cook it.You don't need to cut it into pieces. Be sure to cross the muscles with the knife when you make the jabs. Put some holes in the sides of the fish too. Keep an eye on it as it microwaves. You'll probably have to re-jab the fish as it microwaves.
