Instructions
Step 1: Prepare the seafood
If using frozen seafood, thaw it under cold water and pat dry. Clean the mussels and clams thoroughly. Slice the squid and firm fish, and peel the shrimp if not already done. Set aside.
Step 2: Sauté the aromatics
Heat vegetable oil and sesame oil in a large pot over medium heat. Add minced garlic and ginger, followed by the gochugaru. Stir constantly for about 30 seconds to bloom the chili flakes without burning.
Step 3: Add vegetables
Toss in the onions, cabbage, zucchini, carrots, and scallions. Sauté until slightly softened, about 4–5 minutes. This creates the base of your korean spicy seafood soup.
Step 4: Build the broth
Add gochujang, soy sauce, oyster sauce, sugar, and a dash of pepper. Stir well, then pour in the chicken or anchovy stock. Bring to a boil, then lower to a simmer and let the flavors marry for about 10 minutes. The broth should now be a vibrant red-orange color, smelling spicy and inviting.
Step 5: Cook the seafood
Add the mussels and clams first, as they take the longest. After about 3–4 minutes (when they begin to open), add shrimp, squid, and fish. Let simmer until all seafood is cooked through, about 5–6 minutes more. Discard any unopened shellfish.
Step 6: Cook the noodles
While the soup simmers, cook the noodles according to package instructions. Drain and rinse under cold water to stop cooking and remove extra starch.
Step 7: Assemble the dish
Divide the cooked noodles between bowls. Ladle hot broth and seafood over each bowl generously. Top with scallions, chili slices, or a drizzle of sesame oil if desired.
