Step-by-Step Instructions

Sauté the Vegetables and Aromatics:
Add broth, water, green onions or white onion, low sodium soy sauce, rice vinegar, garlic, ginger, mushrooms, carrots, sesame oil, salt, pepper, and red pepper flakes into the slow cooker. Stir everything well to combine so the flavors meld during cooking.
Slow Cook the Broth:
Set the slow cooker on HIGH for 2 to 3 hours or LOW for 4 to 6 hours. This cooks the vegetables fully and infuses the broth with rich, aromatic layers.
Add Seafood, Ramen, and Bok Choy:
When the broth is ready, stir in the seafood, ramen noodles, and chopped bok choy. Cook uncovered for an additional 15 to 30 minutes, just until the seafood is cooked through and the noodles have softened but still hold their shape.
Instant Pot Variation:
Place the broth ingredients in the Instant Pot and stir well. Secure lid and seal valve. Pressure cook on high for 12 minutes, then quick release. Open lid, add seafood, ramen, and bok choy, then close lid again and set to WARM for 5 to 10 minutes to finish cooking everything gently.

Storage Tips

Cool the soup completely before transferring it to airtight containers for the fridge. It keeps well up to 3 days. If freezing, remove noodles first and freeze broth with vegetables and seafood separately to maintain texture.

Ingredient Substitutions

Swap bok choy for spinach or napa cabbage if preferred. Use tamari instead of soy sauce for gluten free. Any firm seafood like cod or firm white fish can replace shrimp or scallops.

Serving Suggestions

Serve with a slice of crusty bread or a side of steamed dumplings to round out the meal. A drizzle of toasted sesame seeds or a splash of chili oil on top adds extra indulgence.

Cultural Context
