It’s happened to the best of us. Last night’s salmon dinner was so exquisite that you can’t wait to have another serving for lunch. So, you turn to your trusty microwave. You pop in the fish, watching your meal spin on that revolving plate, hungry and eager to open the door. You wait eagerly while the microwave does its thing, and then you grab your plate. You sit down, take a bite … but then, dry, smelly, rubbery fish. Gross.

Salmon is a very unique fish, bursting with flavor and nutrients. One of the reasons for our obsession with this tasty fish is its classification as an oily fish. Salmon is higher in omega-3 fatty acids than many other fish. Omega-3 fatty acids are incredibly important for brain function, memory, maintaining healthy blood fat levels (lowering triglycerides), and a host of other important functions. So important in fact that it’s recommended to eat a portion of oily fish at least twice a week.

If you’re into weekly meal prep or if you made too much salmon to eat in one sitting, you may have found yourself asking, what is the best way to reheat salmon? Let us help you out with some nifty ways to reheat your oceanic meal.

  3. Fold a piece of baking foil loosely over the salmon.
  4. Place the salmon on a baking tray.
  5. Bake the salmon for 15 minutes.
  6. Check to see if the salmon has heated through to an internal temperature of 145 degrees Farhrenheit. If not, cook for additional 5 minutes.

An air fryer is a fantastic way to reheat salmon when you don’t want to heat the whole house by turning on the oven. It’s also a much quicker and very simple process.

  1. Set the air fryer to 360 degrees Fahrenheit.
  2. If your salmon has the skin intact, be sure to place the skin side down on a piece of parchment paper.
  3. Heat for 4-5 minutes, or until salmon is heated through.

Best way to reheat salmon in the microwave

Microwave reheating is infamous for overcooking parts of a dish and undercooking others. It tends to be harsh on delicate meats like salmon; however, the convenience of a microwave cannot be beaten. It’s the most popular appliance for quick and easy reheating. Here lies the secret to reheating salmon in the microwave:

  1. Place salmon in a microwave-safe dish or bowl.
  2. Use a paper towel or a lid to keep moisture in the container and distribute heat effectively.
  3. If your salmon does not have a sauce or if you are not reheating the salmon with other sides like vegetables and rice, you want to ensure that there is sufficient moisture in the container. For dry salmon or if reheating with rice dishes, add a tablespoon of water, lemon juice, sauce, or broth to the container to prevent drying out.
  4. Set microwave power to a low setting — 30% or so will do.
  5. Microwave for 30 seconds.
  6. Remove the salmon, flip, or move with a fork and stir sides like rice and vegetables.
  7. Place back in the microwave for an additional 30 seconds.
