What is Rock Cod Fish or Rockfish?

Rock cod is one of those wonderful white fish that makes dinner so easy. Mild, tender, and incredibly versatile, it works beautifully pan-fried, grilled, steamed, or baked.

This recipe actually started with a piece of ginger sitting in my refrigerator that needed a purpose. I started playing with a few of my favorite Asian flavors, adding honey, rice vinegar, dark soy sauce, and, of course, garlic.

I absolutely love ginger and honey together. The sweetness of the honey softens the sharpness of the ginger, while the soy sauce and vinegar bring everything into balance. Sometimes the best recipes really do come from simply having fun in the kitchen.

What is soy sauce?

Fermented soy sauce is a liquid condiment. It is of Chinese origin.

Traditionally made from a fermented paste of soybeans, roasted grains, and brine.

It is considered to contain a strong umami flavor.

Soy sauce is known as shoyu and soya sauce. It is the fermentation process of soybeans, and salt is used to make it.

Soy sauce contains wheat, also.

While making the soy sauce, the soybeans are soaked in water for several hours. Then the fermented soybeans are steamed. Wheat is roasted, ground into flour, and mixed into the steamed soybeans.

I use soy sauce as a dipping sauce for potstickers. In a small bowl, I mix it with some Japanese rice vinegar.

However, you will find various types of soy sauce on the market. The most common is the Japanese soy sauce: Koikuchi Shoyu, a dark soy sauce. 

And the usukuchi shoyu is a light soy sauce with a mild flavor.

Most recipe call for regular soy sauce, readily available at your local grocery store.

Key Ingredients

Rock cod – Mild, firm, and wonderfully versatile, rock cod is perfect for absorbing the sweet and savory ginger-soy marinade. You can also substitute another firm white fish such as sea bass, snapper, or swordfish.

Fresh ginger – The star of the marinade. It adds warmth, freshness, and that unmistakable little kick that pairs so beautifully with honey and soy sauce.

Soy sauce – Brings deep savory umami flavor and forms the backbone of the marinade.

Honey – Adds just the right amount of sweetness while balancing the salty soy sauce and sharp ginger.

Rice vinegar – Adds brightness and acidity, keeping the marinade fresh and balanced rather than overly sweet.

Garlic – A little garlic adds another layer of savory flavor and works beautifully with the ginger and soy sauce.

Fresh parsley – Adds freshness and a touch of color to the marinade and finished fish.

Olive oil – Just a small amount is needed to pan-sear the fish until beautifully golden while keeping the inside tender and moist.

How to Make Rock Cod in Ginger Soy Sauce Marinade

As with all cooking, have all your ingredients ready before cooking. This recipe is quite straightforward. 

Step 1: Add the honey, soy sauce, rice vinegar, garlic, fresh ginger, and parsley to a food processor or blender. Blend until smooth and well combined.

Step 2: Season the rock cod generously with salt and pepper on both sides. Place it in a shallow dish and pour most of the marinade over the fish, reserving a couple of tablespoons for serving.

Step 3: Let the fish marinate for 30 minutes to 1 hour, turning and basting it occasionally so all sides absorb the ginger-soy flavors. Do not marinate it for longer than an hour.

Step 4: Heat the olive oil in a large skillet over medium-high heat. Remove the fish from the marinade and place it in the hot skillet.

Step 5: Cook the rock cod for about 3 minutes on each side, or until golden on the outside and cooked through.

Step 6: Transfer the fish to a serving platter and drizzle the reserved marinade over the top. Garnish with fresh parsley, if desired, and serve immediately.

The ginger adds that kick of flavor to this ginger soy marinate. However, use as much as you wish or as little as you want of ginger, but do use it.

Giangi’s Pro Tips

Do not over-marinate the fish. The soy sauce and rice vinegar are flavorful enough that 30 minutes to 1 hour is plenty. Any longer and the texture of the cod can begin to change.

Pat the fish dry before cooking. This helps the cod sear beautifully instead of steaming in the skillet.

Use fresh ginger and garlic. They make all the difference here and give the marinade that bright, lively flavor I love.

Keep the skillet hot. A properly heated pan gives the fish a lovely golden exterior while keeping the inside tender and moist.

Turn the fish only once. Cod is delicate, so let it develop a good crust before gently flipping it.

Watch the cooking time carefully. Fish cooks quickly, and overcooking will make it dry. Remove it from the heat as soon as it flakes easily with a fork.

Reserve some marinade before adding the fish. That way, you have a clean, flavorful sauce to spoon over the cod just before serving.

What to Serve with Rock Cod in Ginger Soy Sauce Marinade

With the sweet and savory ginger-soy flavors of this rock cod, I like to keep the rest of the meal simple and fresh. My Bok Choy Stir Fry is a natural choice, especially since the garlic, ginger, and soy flavors complement the fish so beautifully.

I also love serving it with my Butter Rice, which is perfect for soaking up every bit of that delicious sauce. If I want to add something lighter and crisp, a simple green vegetable or salad rounds everything out nicely.

For me, the cod, bok choy, and a generous spoonful of butter rice make an easy, balanced dinner that feels special without being complicated.

Rock Cod Fish In Ginger Soy Sauce Marinade FAQs

Can I use another fish instead of rock cod?

Absolutely. Chilean sea bass, Pacific snapper, red snapper, halibut, or swordfish all work beautifully with this marinade. Choose a firm white fish that will hold together well while cooking.

How long should I marinate the fish?

About 30 minutes to 1 hour is perfect. I would not leave it much longer, as the vinegar and soy sauce can begin to change the texture of the fish.

Can I bake the fish instead of pan-searing it?

Yes. Place the marinated fish in a baking dish and bake at 400°F until it is cooked through and flakes easily with a fork.
