Simple Miso Cod Breakfast Soup

Light miso cod soup is a warm, soothing breakfast that feels gentle on the stomach while delivering protein and minerals in a simple, comforting bowl.

Servings: 1
Total Time: 12 minutes (Prep: 4 minutes | Cook: 8 minutes)

Ingredients

• Cod fillet (3 oz, fresh or frozen)
• Water (2 cups)
• Miso paste (1 tablespoon)
• Baby spinach (½ cup)
• Green onion (1 tablespoon, sliced)

Step 1: Prepare the Cod

If using frozen cod, thaw it completely in the refrigerator or under cold running water. Pat it dry to remove excess moisture, which helps keep the broth clean.

Cut the fillet into small, even-sized chunks so they cook quickly and evenly. This step ensures the fish becomes tender without breaking apart too much during cooking.

Step 2: Heat the Water

Pour the water into a small saucepan and place it over medium heat. Allow it to slowly come to a gentle simmer rather than a rapid boil.

A mild simmer keeps the broth clear and prevents the fish from becoming tough. This gentle heating method also helps maintain the delicate, clean flavor that makes this soup so soothing.

Step 3: Cook the Cod

Carefully add the prepared cod pieces to the simmering water. Let them cook undisturbed for about 4 to 5 minutes. The fish will turn opaque and begin to flake easily when done.

Avoid stirring too much, as cod is delicate and can break apart. Cooking it this way allows the broth to absorb a light, natural seafood flavor.

Step 4: Add the Miso

Reduce the heat to low before adding the miso paste. Place the miso in a small bowl, add a spoonful of warm broth, and stir until smooth, then return it to the pot.

This helps it dissolve evenly without clumping. Avoid boiling after adding miso, as high heat can reduce its flavor and nutritional benefits.

Step 5: Add Greens and Serve

Add the baby spinach directly to the hot soup and let it wilt gently for about 30 to 60 seconds. Turn off the heat once the spinach softens.

Sprinkle sliced green onions on top for a fresh, mild sharpness. Serve immediately while warm to enjoy the comforting texture, balanced flavors, and soothing quality of this light breakfast soup.
