Cook perfectly flaky and fork-tender cod fillets without the hassle of thawing! Simply let the Anyday dish and your microwave do all the work. Using an Anyday dish preserves the moisture and flavor of the cod with each bite.

The secret to cooking fish from frozen in the microwave? Lowering the power level. This makes sure your fish comes out tender, juicy, and not rubbery. Cod fish can tend to have a strong aroma, but cooking cod from frozen in an Anyday dish reduces any potential odors, resulting in fresh smelling (and tasting) fish every time.

All of Anyday’s recipes are tested (and retested!) in many different microwave and home kitchens to make sure they work and work well. Unless specified otherwise, all recipes should be cooked at full power.

Select your microwave wattage in the dropdown. The cook times in this recipe will automatically change accordingly.


To find your microwave’s wattage, look at the front panel, the side of the door, in the back, in the user manual, or Google the model number. If both an input and output wattage are listed, use the output.

Wattage translates to how powerful the microwave is. The higher the wattage, the faster your food will cook. The lower the wattage, the longer the cook time.

When in doubt, start with less time — you can always add more.

The Medium Shallow Dish


  • 1 (115-170g) frozen cod filet, keep frozen
  • salt or seasoning to taste


  1. Place the frozen cod filet in the Anyday dish and season to taste with salt or any spices of your choosing. Cover with lid (knob lifted).
  2. Cook in the microwave at Power Level 8tooltip for 3-5 minutes, or until cod flakes easily with a fork. 
  3. If the fish needs more cooking time, cook in 30-second increments until the cod is cooked through to your liking.

Serving suggestions & tips

  • Garlic and ginger: Season with garlic powder, grated ginger, and black pepper before cooking.
  • Miso soy sauce: Spread with a mixture of miso paste and soy sauce before cooking.
  • Italian pesto: Brush some pesto over the cooked filet and serve with a green salad.
  • Ranch spice: Season with some ranch powder and cayenne before cooking, if you’d like a kick.

Recipe notes

  • Frozen cod does not need to be thawed! (This is the ultimate time-saving hack.)
  • Reducing the power level helps keep the fish tender and juicy and helps avoid a rubbery texture.
  • Make sure to select the proper wattage for the most accurate cook time.
  • Microwave ovens vary, even with the same wattages. Adjust cooking times as needed.

Can I cook frozen cod without thawing it first?

Is the microwave safe for cooking frozen fish?

Yes, microwave cooking is perfectly safe for cooking fish! The Anyday dish is designed to cook food evenly and retain moisture, making it a great option for cooking this delicate protein. Always make sure the fish reaches an internal temperature of at least 145°F (63°C) for safe consumption.

How do I know when the cod fish is properly cooked?

Cod fish is perfectly cooked when it turns pale white and easily separates into tender flakes. If you’d like to use a thermometer, make sure the interior of the fish reaches at least 145°F. To make sure the fish is fully cooked through, test a small piece. Use a fork to gently flake the fillet; it should come apart easily.

How do I store leftover microwaved cod fish?

To preserve leftover microwaved cod fish, store it in an Anyday dish with the lid on in the refrigerator. It should remain fresh for 2-3 days. When reheating, simply microwave for 1-2 minutes, checking occasionally until it reaches the desired temperature.
