Miso Black Cod with Sweet Potatoes and Brussels Sprouts

Pro tips

• Pat the miso black cod dry before baking to ensure even browning and prevent the miso glaze from steaming off.
• Toss Brussels sprouts with balsamic glaze in the final 2 minutes of roasting to prevent the glaze from burning and preserve its acidity.
• Whip the sweet potato mash with a fork or immersion blender for a lighter, fluffier texture; avoid over-mixing to prevent gumminess.
• Line your baking sheet with parchment paper to prevent the miso glaze from sticking and make cleanup effortless.

Substitutions

• Trader Joe's Black Miso Cod → halibut or sea bass fillet (adjust baking time; thicker cuts may need 3–5 minutes longer)
• Balsamic glaze → soy reduction or teriyaki glaze (maintains umami; omit additional salt)
• Honey → maple syrup or agave (1:1 ratio; use to sweeten sweet potatoes or balance balsamic sharpness)
• Ground cinnamon → ginger or nutmeg (1/4 tsp each; adjust to taste)

Storage & make-ahead

Store leftovers in an airtight container for up to 2 days. Reheat fish gently in a 325°F oven to avoid drying out; warm Brussels sprouts and sweet potatoes separately in the microwave or on the stovetop.

Can I use a different fish instead of black cod?

Yes. Halibut, sea bass, or cod work well, though black cod's buttery texture is ideal. If substituting, adjust cooking time based on thickness—aim for flaky, opaque flesh at the thickest point.

How do I know when the miso black cod is done?

The fish should flake easily with a fork and be opaque throughout. The Trader Joe's fillet typically cooks in 12–15 minutes at 400°F depending on thickness.

Can I make the sweet potatoes ahead?

Yes. Mash and store up to 3 days in the fridge, covered. Reheat gently on the stovetop with a splash of milk or water, stirring often, or microwave in 1-minute intervals.

What if I don't have balsamic glaze?

Use 1 tbsp balsamic vinegar reduced with 1 tsp honey in a small pan for 2–3 minutes until syrupy, or substitute soy glaze for an Asian-forward twist.

Is this recipe dairy-free or gluten-free?

The miso black cod and vegetables are naturally gluten-free. Sweet potatoes are typically mashed with butter; use plant-based butter for dairy-free. Check the Trader Joe's miso cod label for gluten or soy content.
