Make easy gluten-free miso-marinated black cod with a sweet and savory glaze, tender flaky fish, and a restaurant-style caramelized finish.
Rich, buttery, and beautifully caramelized, this Easy Gluten-Free Miso-Marinated Black Cod features tender sablefish coated in a sweet and savory Japanese-inspired glaze. Broiling creates a glossy finish with lightly charred edges while keeping the fish moist and flaky.
Although elegant enough for holidays, date nights, and dinner parties, this restaurant-style seafood dish requires very little hands-on preparation. Marinate the black cod for at least 30 minutes or up to 2 days for deeper flavor, then broil it for a quick and impressive dinner.
Serve the fish with steamed rice, sautéed bok choy, roasted vegetables, asparagus, or a crisp cucumber salad for a complete meal.
Prep Time: 30 minutes to 2 days
Cook Time: 10 minutes
Total Time: 40 minutes to 2 days 10 minutes
Yield: 4 servings
¼ cup red miso paste or white miso paste
¼ cup sake
2 tablespoons mirin
2 teaspoons gluten-free tamari
1 tablespoon neutral oil
¼ cup granulated sugar
4 black cod fillets, about 5 to 6 ounces each
Step 1: Prepare the Miso Marinade
In a medium bowl, whisk together the miso paste, sake, mirin, gluten-free tamari, neutral oil, and granulated sugar until smooth and fully combined. The marinade should be thick and glossy enough to coat the fish.
Step 2: Marinate the Black Cod
Pat the black cod fillets dry with paper towels. Spread the miso marinade evenly over all sides of each fillet, making sure every surface is thoroughly coated.
Place the fillets in a resealable plastic bag or airtight container. Seal and refrigerate for at least 30 minutes. For deeper flavor, marinate the fish overnight or for up to 2 days.
Step 3: Preheat the Broiler
Position an oven rack about 4 inches from the broiler element. Preheat the broiler to high.
Line a broiler-safe pan or rimmed baking sheet with aluminum foil for easier cleanup.
Step 4: Prepare the Fish for Cooking
Remove the black cod from the marinade and gently scrape away the excess. Leave a thin layer of marinade on each fillet to create the signature caramelized glaze.
Arrange the fillets skin-side down on the prepared pan, leaving space between each piece.
Step 5: Broil the Black Cod
Place the pan under the broiler and cook for 8 to 10 minutes. The exact cooking time will depend on the thickness of the fillets.
The fish is ready when the top is deeply caramelized with lightly charred spots and the flesh flakes easily with a fork. A thin skewer or knife inserted into the thickest part should slide through with little resistance.
If part of the fish begins browning too quickly, loosely cover that area with a small piece of aluminum foil while the remainder finishes cooking.
Step 6: Serve
Carefully transfer the black cod fillets to serving plates. If necessary, remove any visible pin bones with clean kitchen tweezers while the fish is still warm.
Serve immediately with steamed rice, sautéed bok choy, roasted asparagus, other roasted vegetables, or a crisp cucumber salad.
Black cod is also known as sablefish. Its naturally rich texture and high oil content help it remain moist and tender during high-heat cooking.
White miso gives the marinade a milder, slightly sweeter flavor. Red miso creates a deeper, more robust flavor.
For the richest flavor, marinate the fish overnight. A 30-minute marinade will still produce a delicious result when time is limited.
Watch the fish carefully under the broiler. The sugar in the marinade helps the glaze caramelize but can burn if placed too close to the heating element.
Always verify that the miso paste and tamari are appropriately labeled gluten-free when preparing this recipe for someone with celiac disease or gluten sensitivity.
Prevent cross-contact during preparation.
Store leftover cooked black cod in an airtight container in the refrigerator for up to 2 days. Reheat it gently in a 300°F oven until warmed through. Avoid prolonged reheating, which can dry out the fish.
