Costco Miso Glazed Cod - How to Fix + Cooking Instructions


High Liner Miso Glazed Cod at Costco

Costco sells High Liner Miso Glazed Cod for $19.99. The miso glazed cod can be found in Costco’s frozen food aisles near other frozen seafood such as tempura shrimp, mahi mahi, and salmon burgers.


Costco used to sell the miso glazed cod regularly until they unexpectedly pulled it from the shelves for whatever reason. I’m glad it’s back and super excited to try it again.

High Liner at Costco

Costco carries a few of High Liner’s delicious frozen seafood products. Along with this Miso Glazed Cod, High Liner sells a furikake-crusted cod and a tortilla-crusted tilapia. The tortilla-crusted tilapia is ranked at the top of my Top 30 Frozen Foods at Costco list. 

One big difference between this frozen cod and the rest of the High Liner lineup at Costco is that this cod is not breaded but instead covered in a miso glaze.


According to High Liner, “Sustainability is not an option. It’s the Answer.” I really like that saying, as we must preserve the oceans and wildlife for the generations to come.

High Liner’s cod is wild caught off Iceland’s magnificent coastline in one of the most responsibly managed fisheries in the world, and as a company, they strive to minimize any damage to the ocean habitat and prevent overfishing.

Miso Glazed Cod - Cooking Problems

For my first cook, I followed the recommended instructions, and unfortunately, the cod was quite the disappointment. I cooked the miso cod on a foil-lined baking tray, and during the cooking process, all of the glaze melted off the cod and onto the tray. 

The end result was a piece of plain cod surrounded by a pool of glaze.


I initially thought I made a huge mistake somewhere with the cooking directions, but this seems to be a common complaint with this miso-glazed cod. 

The box recommends that if you grill the fish on a bbq, you should place it in a little foil pouch, but this is a must-do for any cooking method to preserve the glaze. I placed the cod in a foil pouch for my next cook in the air fryer, and the glaze did a much better job staying on the fish. 


I much more enjoyed the air-fried miso cod for a few reasons. First, the glaze stayed on the fish as intended, and the cod did develop a nice crust.


Sadly, even when cooked in the air fryer, the cod was a letdown. The cod itself was fine and was firm and flaky. 

The problem is the miso glaze which just didn’t provide much flavor. Cod is already known for its mild flavor, and the miso-glazed doesn’t do much to help it. The glaze is very subtle and just doesn’t wow.


Because of the issues with the cook and the lack of flavor in the glaze, I can’t recommend this item as a buy.

Costco Miso Glazed Cod Cooking Instructions

There are two methods to cook the miso glazed cod from Costco: bake it or grill it. I also recommend air frying the miso glazed cod for a faster cook time and a crispier exterior. I will be including my own personal air fryer instructions below as well.

During my cooks, the miso glaze ran off the cod, and I highly recommend creating little foil pouches to keep the glaze contained for any of the cooking methods. 


To Bake

Arrange the rack in the center of the oven, preheat, and place frozen fillets on a shallow foil-lined baking pan. 

Conventional Oven

  • Bake at 400°F for 18-22 minutes.
  • Let stand for 2 minutes before serving.

Convection Oven

  • Bake at 375°F for 17-19 minutes. 
  • Let stand for 2 minutes before enjoying.

To Grill

  • Preheat to medium-high heat. 
  • Place frozen fillets on a piece of aluminum foil and crimp foil edges together to form a pouch.
  • Grill for 16-19 minutes.
  • When ready to serve, drizzle the remaining sauce from the pouch over the fish.

Air Fryer Cooking Instructions (Recommended)

  • Preheat Air Fryer to 380°F
  • Place Miso Glazed Cod in a foil pouch
  • Place cod and foil in the air fryer and cook for 13-15 minutes.
