What Is Chilean Sea Bass?

Chilean sea bass (also known as a Patagonian toothfish) is a flaky fish with mild flavor. It’s found the cold waters of the southern Atlantic, Pacific, and Indian Oceans. Usually between 45 and 3,850 meters. The fish itself is not the prettiest youโ€™ll ever lay eyes on. However, it is one of the most sought-after and flavorful fish in the world.

It has a flaky, buttery texture and should be cooked in the air fryer, hot skillet, or oven for best results. It can be made in a variety of ways. One of the most popular variations is made with fresh dill, capers, minced garlic, and a lemon butter sauce.

This fish comes at a higher price point, so it’s perfect for special occasions.

Miso Glazed Sea Bass ingredients

This beautiful white sea bass dinner comes together with very few ingredients, but will leave you feeling like the master chef you are!

  • Two 6oz chilean sea bass fillets
  • 1 tablespoon unsalted butter
  • 1/4 cup white miso paste
  • 1 tablespoon rice wine vinegar
  • 4 tablespoons maple syrup (honey works too!) 
  • 2 tablespoons mirin
  • 1/2 teaspoon ginger paste

Optional Toppings: 

  • Sesame Seeds
  • Sliced Green Onions

A few notes about the ingredients:

If you don’t have mirin on hand you can still make the glaze without it. It’s not an essential ingredient, just adds to the flavor and texture of the glaze.

You can use red miso paste if you have that on hand already or can’t find white miso paste in the store.

WHAT IS MISO PASTE? 

Miso Paste is very popular in Japanese culture; Miso is a traditional seasoning you will find in many of their dishes. It is made by fermenting soybeans with salt and cooked rice. There are many different colors of Miso Paste: White, Yellow, Red, and Black. However, White and Red Miso paste are the most common.

White Miso: White Miso (the miso recommended for this recipe) is made from soybeans that have been fermented with a very large percentage of rice. The actual color of the miso can range from white to light beige and carries a sweeter taste compared to the other Miso Paste options.

Red Miso: Red Miso is made from soybeans fermented with barley and other grains. The color ranges from red to dark brown and carries a heartier flavor perfect for hearty soups and glazes.

WHAT DOES MISO PASTE TASTE LIKE?

Miso generally has a salty yet tangy savory flavor that is very much itโ€™s own. The color of the Miso Paste used changes/effects the taste/flavor.

Where Can I Find Miso Paste?

Miso paste is usually in the refrigerated section near the tofu. In my local grocery store, it’s located near the produce and refrigerated vegan products. You can always an employee for help if you’re having trouble!

WHAT IS MIRIN?

Mirin is another essential ingredient in Japanese cooking. Mirin is a type of rice wine similar to sake, but lower in alcohol content and higher in (naturally fermented) sugar.

A good substitute for Mirin is 1-2 tablespoons of sugar and 1/2 cups for white wine, Vermonth, or dry sherry. 

Mirin is usually found in the ethnic foods section of the grocery store, with other Asian products.

How to make Miso Sea Bass

1. Cook the fish. Preheat your air fryer to 375F. Next, you will brush a thin layer of olive oil over each fillet of fish. The best way to season it is with some fresh cracked black pepper or lemon pepper. You can add a sprinkle of kosher salt if you like, but I don’t think it needs it.

Spritz the air fryer pan with olive oil and place the fish SKIN side DOWN. Cook for 12-15 minutes, until the top beings to turn golden brown.

2. Prepare the miso glaze. While the fish is cooking, melt the butter in a small saucepan over medium heat. When the butter has melted, add the miso paste, rice wine vinegar, maple syrup, mirin, and ginger paste. Stir until fully combined, bring to a light boil, and remove the pan from the heat immediately.

3. Glaze the fish. Once the fish is finished, use a silicone pastry brush (or the back of a spoon) and brush the glaze over the top and sides of the fish. Place the fish back into the air fryer for 2 more minutes (at 375F), until the glaze has caramelized.

4) Optional: Finish with sliced green onions and/or sesame seeds.

Ingredients

  • 2 6 ounce chilean sea bass fillets
  • 1 tablespoon unsalted butter
  • 1/4 cup white miso paste
  • 1 tablespoon rice wine vinegar
  • 4 tablespoons maple syrup, honey works too!
  • 2 tablespoons mirin
  • 1/2 teaspoon ginger paste

Instructions

  • Preheat air fryer to 375ยฐ F. Brush olive oil all over each fillet of fish and finish with fresh cracked pepper. Spritz the air fryer pan with olive oil and place the fish skin side down. Cook for 12-15 minutes, until the top begins to turn golden brown and the internal temperature has reached 135ยฐ F.
  • While the fish is cooking, melt the butter in a small saucepan over medium heat. When the butter has melted, add the miso paste, rice wine vinegar, maple syrup, mirin, and ginger paste. Stir until fully combined, bring to a light boil, and remove the pan from the heat immediately.
  • When the fish is finished, use a silicone pastry brush (or the back of a spoon) to brush the glaze over the top and sides of the fish. Place it back in the air fryer for 1-2 more minutes at 375ยฐ F, until the glaze caramelizes. Finish with sliced green onions and/or sesame seeds.

Oven Instructions

  • Preheat the oven to 425ยฐ F and line a baking sheet with foil lightly sprayed with olive oil. Bake for 20-25 minutes, depending on the thickness of your fish. The internal temperature should be 135ยฐ F when the fish is cooked through.
  • Remove the fish from the oven and preheat the broiler to high. Brush the miso glaze over the fish (top and sides) and place it back in the oven on the top rack. *If your rack is too close to the broiler, move it down a bit, you don't want the fish to touch it!* Cook the fish for 1-2 minutes under the broiler, until it begins to caramelize. Keep a close eye on it because it happens quickly! Finish with sliced green onions and/or sesame seeds.

    Glaze was absolutely amazing. Would love to put it on everything! Cooked an 8 oz. piece of sea bass in my air fryer and it was perfectly cooked after 15 initial minutes and 2 minutes with the glaze. Served with jasmine rice and sauteed spinach. Perfect dinner!

  2. 5 stars
    Best fish recipe ever!! I made extra sauce to make it again even faster!! Works great with Wild Cod too!

  3. Tammy Ortega says:

    Do you need parchment paper in the air fryer or just the fish with sauce? I’m still getting used
    to my air fryer.

    1. You do not, but you can use it if you like. Just make sure you buy the one that has holes so the air can flow through.

    This was SO GOOD! I love that you donโ€™t need to marinate the fish for a couple days. Delicious and easy! I also made the bok choy and that was also great! Iโ€™ll definitely be making this again!

  9. 5 stars
    This recipe was delicious! The glaze was not over sweet and filled with lots of umami flavor. I loved JZ Eats direction of cooking the fish in the air fryer first and then finishing it with the miso glaze. It couldn’t have turned out any better. Definitely saving to make this a staple!

    1. Thank you so much Molly!

  10. 5 stars
    This was a fabulous recipe and I am now using the sauce for other things. Can’t thank you enough.

  11. Hi,
    I was about give this recipe a go but I was unclear on ‘rice wine vinegar’. There is rice wine & rice vinegar but not a rice wine vinegar. You mentioned in the FAQ to get Mirin which is a rice cooking wine but in your amazon link it goes to a product for rice vinegar. Can you clarify which product it should be please?

    1. Hi Lindsay! Sorry for the confusion. You will need mirin and rice vinegar. If you donโ€™t have mirin, you can substitute with a 1/2 tsp of sugar and an extra tbsp of rice vinegar.
