How Long to Cook Salmon in Microwave Oven [2024]

Cooking salmon in the microwave is a swift and convenient method to whip up a tasty meal, particularly when you’re strapped for time. To get started, make sure your salmon filets are defrosted; ideally, you should thaw them in the refrigerator overnight or use the microwave’s defrost setting if you’re pressed for time. Once thawed, place the fillet in a microwave-safe dish, season it with some lemon juice and your preferred seasonings to enhance its flavor.

How Long to Cook Salmon in Microwave Oven? To cook salmon in a microwave oven, microwave it on high for 3 to 4 minutes per half-inch of thickness. Check for doneness by ensuring the fish flakes easily with a fork. Let it rest for a few minutes before serving.

For a perfectly cooked salmon in the microwave, the typical cook time is about 3 minutes, though this can vary based on the thickness of your fillet and the power of your microwave. It’s crucial to check the salmon’s doneness by looking for a flaky and opaque appearance throughout. Take care not to overcook the fish, as it can quickly become dry and tough in the microwave. If you want a full meal, consider adding vegetables like asparagus in the same dish, adjusting the total cooking time accordingly. To reheat previously cooked salmon, do so gently to preserve its moist and tender texture.

Quick and Easy Guide: How Long to Microwave Salmon for a Perfect Dinner

Microwaving salmon is a convenient and quick method to prepare a nutritious and delicious dinner. This guide will walk you through the simple steps to ensure your salmon is perfectly cooked using a microwave, any day of the week.

Preparing Your Salmon

Before you start, if you’re using frozen salmon, make sure to defrost it thoroughly. The best way to defrost salmon is in the refrigerator overnight, but if you’re short on time, using the microwave’s defrost function is also an option. Once defrosted, place the salmon in a microwave-safe dish suitable for cooking. To season the salmon, sprinkle it with salt, pepper, and if you like, some lemon pepper for that zesty touch. This simple preparation helps enhance the natural flavors of the fish without overpowering it.

Cooking the Salmon

When you’re ready to cook, cover the salmon with microwave-safe plastic wrap; this helps keep the salmon moist and also traps in the heat for even cooking. Microwave the salmon on high power for about 3-4 minutes. The exact time might vary depending on the thickness of the salmon and the type of salmon you’re using. After the initial cooking, check the internal temperature of the salmon – you’re aiming for 145°F (62.8°C) to ensure the salmon is fully cooked and safe to eat. If needed, microwave for another minute or two but watch closely to prevent overcooking.

Checking Doneness and Serving

Always check the salmon for doneness before serving. The salmon is perfectly cooked when it’s flaky and opaque throughout. If it still appears translucent, microwave it for another 30 seconds and check again. Once done, let it sit for a couple of minutes; this helps redistribute the juices inside the salmon, making it even more succulent. Serve your perfectly microwaved salmon with your favorite sides. A squirt of lemon juice right before serving can also help eliminate any fishy smell and enhance the freshness.

Additional Tips

  • Keep the salmon covered during cooking to avoid drying it out.
  • Lower power settings can be used for thinner pieces of salmon to prevent them from cooking too quickly on the outside while still raw in the center.
  • You can also cook salmon with different seasonings like garlic or dill to vary the flavors throughout the week.


In conclusion, mastering the microwave as a tool for cooking fresh fish like salmon can open up new culinary possibilities, from quick dinners to simple gourmet treats. By understanding the basics of microwave cooking, such as using a microwave-safe lid to seal in moisture and prevent dryness, and adjusting the power levels to suit the thickness of the fillet, you can ensure that your piece of fish is cooked perfectly every time.

Remember to check for doneness with a thermometer—aiming for an internal temperature of 63°C (145°F) and adjust cooking times in 1-minute intervals if necessary. Always allow for residual heat to finish the cooking process, which helps achieve that ideal texture and flakiness. Sprinkle a bit of salt or a dollop of margarine before cooking to enhance flavor, and perhaps experiment with poaching your salmon in a small bowl of cream cheese for a creamy finish.

This method not only provides a quick way to prepare a healthy meal rich in omega-3 fatty acids but also offers a reliable option for reheating leftovers without sacrificing quality. Whether you’re a seasoned cook or a beginner, these step-by-step techniques can help you leverage your microwave to its fullest potential, transforming how you approach cooking fish at home.
