Ingredients
  

For the Miso-Glazed Cod:

  • 2 6 Oz Cod Filets or other flaky white fish like halibut, black cod
  • 2 tbsp white miso paste
  • 1 tbsp mirin
  • 1 tsp low-sodium soy sauce or tamari
  • 1 tsp fresh ginger, grated
  • 1 tsp maple syrup or honey (adjust sweetness to taste)
  • 1/2 tsp sesame oil

For the Bok Choy & Shiitake Sauté:

  • 1 tbsp avocado oil or extra virgin olive oil
  • 6-8 oz baby bok choy, washed and halved or quartered lengthwise
  • 4-5 oz shiitake mushrooms, stemmed and sliced
  • 1 clove garlic, minced
  • 1 tsp fresh ginger, grated
  • 1 tsp low-sodium soy sauce or tamari
  • 1 tsp mirin (optional, for extra glaze)

Garnish (Optional):

  • Sesame seeds (white or black)
  • 1-2 Chopped green onions

Instructions
 

  • Flavor Miso Magic (Marinate): In a small bowl, whisk together the white miso paste, mirin, soy sauce, grated ginger, maple syrup (or honey), and sesame oil until smooth.
  • Cod Marinate Time: Pat the cod fillets dry with a paper towel. Place them in a shallow dish or a zip-top bag. Pour the miso glaze over the cod, ensuring both sides are coated. Marinate in the refrigerator for at least 30 minutes, or up to 1 hour (longer can make it too salty).
  • Preheat & Prep: Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper for easy cleanup.
  • Cod Bake Off: Remove the cod from the marinade (discard excess marinade). Place the cod fillets skin-side down (if skin-on) on the prepared baking sheet.
  • Bake Beautifully: Bake for 10-12 minutes, or until the fish is flaky and cooked through. For an extra caramelized glaze, you can briefly broil for the last 1-2 minutes, watching carefully to prevent burning.
  • Veggie Time: While the cod bakes, heat the avocado oil in a large skillet or wok over medium-high heat. Add the sliced shiitake mushrooms and sauté for 3-4 minutes until softened and slightly browned.
  • Bok Choy Brilliance: Add the bok choy (cut-side down first for a nice sear) to the skillet. Cook for 2-3 minutes, then add the minced garlic and grated ginger. Sauté for another minute until fragrant.
  • Soy Glaze Finish: Pour in the soy sauce (and mirin/red pepper flakes if using) over the vegetables. Toss quickly to coat and cook for just another minute until the bok choy is tender-crisp.
  • Assemble Your Plate: Carefully transfer the Miso-Glazed Cod to serving plates. Arrange the sautéed bok choy and shiitake mushrooms alongside.
  • Garnish & Glow: Sprinkle with sesame seeds and chopped green onions or cilantro for a beautiful finish. Serve immediately and prepare for pure culinary bliss!

Chef's Wisdom & Flavor Finessing Tips:

  • Make it Crispy: For an extra textural contrast, pan-sear your cod for 2-3 minutes per side in a hot, non-stick pan before baking. This gives it a lovely crust!
  • Veggie Swap-Out: No bok choy? Try spinach, asparagus, or green beans! Any quick-cooking green vegetable will work beautifully with the soy glaze.

Why Miso Glazed Cod with Bok Choy and Shiitake Mushrooms is So Healthy

Lean, high-quality protein from cod

  • Cod is a white fish that’s low in fat yet rich in high-quality protein, which supports muscle repair and keeps you feeling satisfied.
  • It's also a good source of vitamin B12, which is essential for nerve health and energy production, and selenium, a powerful antioxidant that supports thyroid function and immunity.
 
Heart and brain benefits from omega-3s
  • While cod isn't as fatty as salmon, it still contains some omega-3 fatty acids, which help lower inflammation, support heart health, and aid brain function.

Gut-friendly, immune-supporting miso

  • Miso (fermented soybean paste) is rich in probiotics, which support a healthy gut microbiome and boost immune defenses.
  • It also adds deep umami flavor, reducing the need for excess salt or heavy sauces.

Nutrient-dense bok choy

  • Bok choy is a cruciferous vegetable packed with vitamins A, C, and K, calcium, and antioxidants. These support bone health, immunity, and help fight inflammation.
  • It's also low in calories but high in fiber, aiding digestion and promoting fullness.

Shiitake mushrooms for immune and heart health

  • Shiitake mushrooms contain beta-glucans and other compounds that help enhance immune function and lower cholesterol levels.
  • They also provide B vitamins and minerals like copper and selenium.
