Step‑by‑Step Instructions for Asian-Style Braised Cod
Step 1: Preheat Oven
Begin by preheating your oven to 350°F (175°C). This ensures that your Asian-Style Braised Cod bakes evenly and thoroughly, allowing the flavors to meld beautifully while the cod cooks. While it heats, gather your ingredients so everything is within reach for a seamless cooking process.
Step 2: Sauté Aromatics
In a large ovenproof skillet, add 2 tablespoons of avocado oil over medium-high heat. Once the oil shimmers, add 1 tablespoon of minced ginger and 2 cloves of minced garlic. Sauté for 1-2 minutes until they are fragrant and golden, stirring frequently to prevent burning. The warm aroma will fill your kitchen, signaling that your dish is underway.
Step 3: Sear Cod
Carefully place your 4 cod fillets into the skillet, cooking each side for about 2 minutes. As they sear, look for a light golden crust to form, which adds depth to the flavor. Once both sides are beautifully colored, remove the fillets from the skillet and set them aside on a plate while you prepare the sauce.
Step 4: Prepare Sauce
In the same skillet, reduce the heat to medium and whisk together ¼ cup soy sauce or tamari, 1 tablespoon rice vinegar, 1 tablespoon erythritol, 1 teaspoon sesame oil, and ½ teaspoon red pepper flakes. Stir until well combined, allowing the sauce to bubble gently for a minute. This braising sauce will infuse the cod with delicious umami flavors.
Step 5: Toss Bok Choy
Add 4 cups of chopped bok choy to the skillet with the sauce, tossing gently for about 2-3 minutes until the bok choy starts to wilt. The vibrant greens will soften slightly but retain a satisfying crunch, creating a lovely base for your cod. Ensure the bok choy is well-coated with the flavorful sauce for maximum taste.
Step 6: Combine & Braise
Return the seared cod fillets back into the skillet, placing them on top of the sautéed bok choy. Transfer the entire skillet to the preheated oven and braise for 12-15 minutes. Keep an eye on the cod as it cooks; it should become opaque and flake easily with a fork, indicating that the fish is perfectly prepared.
Step 7: Garnish
Once you take the skillet out of the oven, let it rest for a minute. Finish your Asian-Style Braised Cod by garnishing with ¼ cup of sliced green onions and a sprinkle of sesame seeds. This final touch adds a pop of color and flavor, making your dish visually appealing and ready to serve.

- Savory Sauce Balance: Adjust your soy sauce or tamari for a depth of flavor. A little can go a long way; taste as you go!
- Perfectly Sear It: Don’t rush the searing process. A golden crust locks in moisture and creates a delightful contrast to the tender fish.
