This easy approach to poached salmon turns out buttery, flawless fish. The trick to getting domino-fall flakes of salmon? Microwave it in a simple saltwater solution at full power and let it rest for an equal amount of time before serving. The water both seasons the fish and helps it cook evenly. You can add a teaspoon of sugar or syrup to the saltwater to add a subtle sweetness, and aromatics, such as rosemary or dill to create additional layers of flavor. If you have time, you can brine the salmon as long as overnight in the refrigerator, which helps reduce the albumin (the harmless white protein that gathers on the surface of the fish during cooking). Most microwaves range in power levels from 600 to 1200 watts. This formula was developed in a 1000-watt microwave that boils one cup of cold tap water in 2 minutes. Cooking speeds on microwaves vary, even among those with the same wattage, so this recipe calls for checking your fillet early to avoid overcooking.

Preparation

  1. Step 1

    Fill a microwave-safe dish that can hold the salmon snugly with the water. Add the salt and stir to dissolve. Add the salmon, skin side down, and baste by spooning the saltwater over it. The top of the fillet should stick out of the saltwater (see Tip). Loosely cover with a microwave-safe lid or plate.

  2. Step 2

    Microwave the salmon at full power (high) for 3 minutes. Check for doneness by inserting a sharp paring knife into the center of the fillet. If it slides in easily without resistance, the salmon is done. It should take about 4 minutes for medium-rare doneness and about 5 minutes for medium, but the time may vary because every microwave cooks differently.

  3. Step 3

    Let the fish sit, still covered in the dish, for 4 to 5 minutes. Remove from the water and serve.

Tips
  • This formula below was designed for farm-raised Atlantic salmon, which has a high fat content. For wild varieties, which are leaner and less thick, reduce cooking and resting times by half.
  • The salmon should be surrounded by but not submerged in the water. If the dish is larger, add more saltwater as needed, dissolving 1 teaspoon salt in each additional cup of lukewarm water.

Cooking Notes

The big unaddressed question: Does it smell up the house?

I’ve made this many times using Italian dressing from the bottle - or whatever type I have - instead of water. It’s delicious, full of flavor, and done in less than 5 minutes. A great go-to on busy days.

As a salmon lover who prefers roasted or pan-seared versions of it, I was skeptical when I first read this. But the salmon was perfect on the first try. The poaching results in very moist, evenly cooked fish that's perfectly seasoned with the salt alone. The second night I did add garlic powder, lemon juice, bay leaf and thyme -- even better. Dinner was ready in 7 mins and no messy cleanup. A must-try.

I usually purchase a 2 lb bag of individually wrapped salmon frozen fillets. After rinsing the frozen fillet under cold running water. I slightly score it & squeeze ½ lime on it (citrus reduces the odor of fish in the microwave). Defrost @ #3/3½ min/1200 wt oven. The H2O & lime juice are sufficient to keep the fillet moist during cooking. Add more lime & herbs, cooking a 168 g./6 oz. filet (with skin) @ #5/ 4-5 min/1200 wt oven.

I cook all types of fish in the microwave, particularly in the summer when I don’t want to heat up the kitchen. I brush the bottom of the dish with olive oil, put the fish in skin side down, add a small amount of white vermouth, and top with fresh herbs. I also find that pricking the fish with a sharp fork keeps it from exploding. I use a Corningware dish with a lid. Then I microwave on a low setting for three to four minutes, checking the fish again, and repeat until done.

I make this often and strongly suggest using an insta-read thermometer rather than the sliding knife test to prevent overcooking. 125–130 F is my preferred end temperature for a probe in the fillet’s center.

I like your bottled dressing suggestion. I am thinking you are just coating the fish with dressing and not replacing the 2 cups of water with 2 cups of dressing. Correct?

I have been cooking salmon in the microwave for years. I coat it with Dijon mustard, lemon, dill if I have it and capers. There is no odor in the house and the salmon is perfectly cooked. Just go slow and don't overcook it. I start with about 3 minutes and check it.

Thanks for this! I nuked a couple of salmon pieces on three springs of rosemary and some thin slices of red onion. I used leftover chicken stock instead of water. It came out perfectly. Who'd a thunk?!? What an easy recipe and such a great substitute for my usual and often less healthy "raid the fridge" approach to dinner after a workday.

About 40 years ago I was visiting a dear elderly friend who invited me for dinner. She pulled two small, white packages (about 5” square) out of her refrigerator and placed them in the microwave and set the microwave for a few minutes. The local supermarket butcher had prepared the salmon for her wrapped in parchment paper. I was fascinated by the delicious salmon since other raw meats prepared in a microwave were an absolute failure! This is another way to poach salmon in the microwave.

No saltwater solution for me.Make a lemony,mustard hot sauce marinade and micro in parchment paper pouch.

Microwaving is our favorite way to cook salmon! We skip the brine, just salt lightly, add garlic powder and black pepper, then dot with butter. Cover and microwave at full power (1000 watts) for 5 minutes and rest for 3-5 min. It is mouth-watering, yet oh, so simple! Without the water, make sure it is patted dry and covered before cooking, as it may spatter.

I like the idea of layering herbs or scallions underneath - might try lemon slices also.

I just made it with a cod fillet tonight, and it worked fine. After the first 2 minutes I checked every 30 seconds until it passed the knife test. I didn't need the full 5 minute rest - once the fish flaked easily, I pulled it out of the water and served it. Note that this is a fairly bland cooking method, so you may want to have it with something full-flavored.

I had been cooking fish filet in microwave for years. It’s easy, fast cooking with no fuss, a tasty meal in a flash.

Does NOT smell up the house :-). Tender salmon, and easy peasy, fast recipe, easy cleanup. Remember the that the salmon keeps cooking while it's resting.

This is fantastic. Biggest return for the littlest amount of time. I serve it with air fryer Brussels sprouts to combine soft with crispy.

You don't even have to defrost. Use a lower power setting (6/10) for about 2x as long. Turn it over when it appears cooked halfway up the sides. Thinly sliced lemon on top reduces any fishy smell, but it's not essential. If eating it right away, sometimes I'll pan fry on high for 2 minutes each side -- still more evenly cooked than pan frying alone. Otherwise, from the microwave to the fridge to put on salad later.

Wow! So flavorful and easy. This is a keeper.

Quick question, is the salmon always so pale? I was looking at the image and the salmon looks almost uncooked!

Needed a little more time in my microwave. Perfectly cooked after 5 minutes. I had brined the salmon, but that doesn't seem necessary. A hit with my dinner party even though it was quite mild. I'll probably pair it with a dressing next time.

I didn't see many/any comments about the potential smell caused here, so optimistically decided to soldier on, hoping that maybe the water and covering the dish would contain the fish smell? Reader, it didn't work. The water acts more like a mist diffuser, spreading the smell across the room. If you or anyone you live with the sensitive to smells, this might not be the cooking method to try. Fish tasted great though!

Yummy, quick & easy cleanup. Definitely a keeper recipe!

I made it with salty water with the salmon resting on fresh rosemary. It was quick, easy and delicious! The fragrance while cooking was intoxicating, thanks to the rosemary. I used a thermometer to determine if it was done. Next time I will try vermouth as suggested by another reader. I used flash frozen sockeye salmon from Alaska. So glad the local grocer carries this product.

This is an excellent dish. It would be even better with a lemony hollandaise-type sauce to spoon over the salmon.

This is essentially poached salmon in the microwave. I brined it for about 6 hours in the fridge along with a squeeze of lemon and some fresh parsley because that was the only fresh herb I had on hand. Probably dill would have worked better but all in all it’s pretty bland. That being said I would definitely continue poaching salmon in the microwave and then add a nice sauce for serving.

Should have known when it called for farmed salmon. PLEASE don't eat farmed salmon unless you know from where it is sourced. Hoped this would be a good alternative to cooking salmon with dry heat, but it was not. In fact, it was pretty bad. Won't try again.

I've read all of the comments and am so excited to try microwaving salmon, one of my favorite fishes! Beyond that, I've enjoyed being in the (digital) company of fellow foodies! Thanks!

Easy recipe but not as flavorful as when I cook it on stovetop.

Try salting the water with miso. Delicious.
