3 tablespoons white miso paste

1 1/2 tablespoons soy sauce or tamari

1 tablespoon brown sugar or coconut sugar

1 tablespoon olive oil or avocado oil

2 cloves garlic, finely minced

1 teaspoon fresh grated ginger

1/4 teaspoon freshly ground black pepper

Step-by-Step Instructions

1

Pat fish dry and season

Use paper towels to gently pat the sea bass fillets dry on both sides, then place them on a parchment lined baking sheet and season lightly with black pepper.

2

Whisk the glaze

In a small bowl, combine white miso paste, soy sauce, brown sugar, lemon juice, olive oil, minced garlic, and grated ginger, whisking until smooth and glossy.

3

Spread half the glaze on the fish

About thirty minutes before cooking, spoon half of the miso mixture over the fillets and spread it gently to coat, letting the fish sit at room temperature while you preheat the oven.

4

Preheat the oven and prepare the pan

Preheat your oven to 400 degrees Fahrenheit and line a rimmed baking sheet with foil for easy cleanup, placing a wire rack on top if you want excess fat to drip away.

5

Bake for most of the cook time

Bake the sea bass for 12 to 15 minutes, depending on thickness, until the fish is just opaque in the center and flakes gently with a fork.

6

Glaze again and broil

Brush the fillets with the reserved miso glaze and switch the oven to broil for 2 to 4 minutes, watching closely until the top turns shiny and lightly caramelized.

7

Rest briefly before plating

Let the fish rest on the pan for a few minutes after broiling so the glossy glaze settles into the tender flesh.

8

Garnish and serve

Scatter sliced scallions over the fillets, sprinkle with sesame seeds if using, and serve immediately with steamed rice or crisp vegetables.

9

Pair with simple sides

Serve with steamed rice, roasted asparagus, or a light cucumber salad to balance the rich miso flavor.

Pro Baker Tips

✓Do not skip the room temperature rest, it helps the fish cook more evenly and prevents flaking

✓Keep a close eye during the broiler stage, miso can go from perfect to burnt very quickly

✓For extra aroma, add a few thin slices of scallion and a drizzle of toasted sesame oil before serving

Storage & Serving Notes

◆Refrigerate leftover fish in an airtight container for up to 2 days and reheat gently in a low oven or skillet to retain moisture

◆Keep the extra glaze in the fridge for up to a week and use it to toss noodles or brush on grilled vegetables

Frequently Asked Questions

Can I use frozen Chilean sea bass?

Yes, make sure the fillets are fully thawed and patted dry before glazing for the best texture and caramelization.

What if I do not have white miso

Light or yellow miso works well and gives a slightly milder, sweeter sauce compared to red miso.

Is this dish family friendly

Absolutely, just serve milder portions for kids and keep extra glaze on the side for dipping.

Can I double the glaze

Yes, doubling the glaze works great, just give it a quick whisk in case the sugar has clumped.
