How to Microwave Cod Fillets: A Quick and Easy Seafood Dish

Microwave cooking has come a long way since the early 20th century.

Nowadays, it’s common practice to use a microwave for anything from reheating leftovers to cooking full meals.

While many still have their reservations about using this method of meal preparation, microwaving can be an efficient and healthy way of cooking your food.

How to Microwave Cod Fillets

If you’re looking for a quick and easy seafood dish that’s healthy and delicious, microwave cooked cod fillets are the perfect choice.

In this post, we’ll share how to cook cod fillets in the microwave while exploring its benefits, precautions, expert tips, advantages and disadvantages.

Why You Should Consider Microwaving Cod Fillets

Microwaving can provide several benefits when cooking meat or fish. Here are some reasons why you should consider microwaving your next seafood dish:

Saves time

Microwave cooking is quicker than traditional methods like baking or broiling which can take 20-30 minutes or more depending on the recipe. With microwaving cod fillets, you can cut down cook time to just a few minutes without sacrificing flavor or texture.

Retains nutrients

Cooking methods like boiling or broiling can lead to nutrient loss due to high temperatures or extended exposure times. Conversely, microwaving doesn’t require water so there is less leaching of nutrients from the fish during the cooking process.

Easy clean-up

Clean-up for microwave-cooked food is generally easier compared with traditional methods because there are no pots and pans used during cooking – just simply remove your fish from its container after it’s done cooking!

Step-by-Step Guide on How To Microwave Cod Fillets

Now let’s dive into our step-by-step guide on how to prepare restaurant-quality cod in your own kitchen:

Step 1: Prepare ingredients

Remove any bones from your cod fillets and rinse them with cold water. Pat them dry with paper towels and season your fish with your desired seasoning mix.

Step 2: Add liquid ingredients

Add a tablespoon of water or broth to the bottom of a microwave-safe container, followed by the seasoned cod fillets.

Step 3: Cover and Microwave

Cover the container tightly with plastic wrap or a microwave-safe lid. Microwave on high for 3-4 minutes per pound depending on your wattage. You’ll need to adjust cooking time if you’re cooking more than one pound; alternatively, cook in batches according to personal preference.

Step 4: Check for doneness

Check whether your cod fillets are cooked through by cutting into one of them in half to see if it’s opaque (whitish) all throughout. If it’s still pinkish-white in some areas, you may need to microwave for an additional minute until fully cooked through.

Precautions for Microwaving Cod Fillets

While microwaving is convenient and easy, there are certain precautions that should be observed when using this method:

  • Always use a microwave safe dish that is appropriate for your recipe.
  • Maintain at least an inch of space between the dish’s rim and its contents.
  • Avoid placing metal or aluminum foil inside the microwave as this could cause a fire – although this shouldn’t be an issue when microwaving cod fillets!
  • Do not overcook as this can cause drying out which makes the fish tough instead of tender.

Factors Affecting Cooking Time

The appropriate cooking time for microwaving cod fillets can vary depending on factors like wattage, type of sauce used or thickness of material used to cover the dish. Here are some important factors affecting cooking time:


If your microwave has high wattage then cooking times may be shorter than stated above.

Type Of Sauce

Depending on the sauce or marinade you use, this may change the length of time needed to cook.

Thickness Of Dish

The more uneven your dish is, the longer it’ll take to cook things evenly all throughout.

Expert Tips for Perfectly Microwaving Cod Fillets

To further improve your microwaving skills when cooking cod fillets, here are some expert tips:

Plan ahead

If you’re preparing several dishes at once, plan accordingly so that everything can be cooked and served within a reasonable amount of time. This helps ensure that each dish gets individual attention rather than risking overcooking while waiting on other dishes to finish.

Time management

Timing is key – particularly with microwaving. If you overcook, the fish will be tough and dry.

Test before serving

Be sure to check your cod fillets throughout the cooking process; this ensures they’re fully cooked before presenting them onto your dining table!

Advantages of Microwaving Cod Fillets

Microwave-cooked meals offer a number of advantages in terms of speed, convenience and simplicity. Here are three key advantages:

Cooking time significantly reduced

Thanks to shorter cooking times with less preparation required, microwave-cooked cod fillets mean that busy individuals or families don’t have to sacrifice healthy eating.

More economical

Microwave ovens are energy efficient and require less power than other cooking methods. Therefore microwaving is cheaper in utility bills than oven baking.

Minimal clean-up

With no pots or pans used during microwave cooking – just one container – clean up has never been easier!

Disadvantages of Microwaving Cod Fillets

Although there are many benefits associated with microwave cooking, there are also some downsides too. Here are three potential disadvantages:

Possible drying out

Overcooked food can easily become dry due to prolonged exposure inside a powerful microwave oven.

Uneven heating

During microwave cooking, it’s easy for parts of the food to heat up faster than others due to variables like wattage and moisture, so it’s essential to check your food throughout the cooking process.

Limited cooking space

The microwave oven dimensions typically limits the amount of food one can microwave cook compared with larger traditional ovens.

Frequently Asked Questions about Microwaving Cod Fillets
