Sauté the Garlic & Spices: In a large pot, melt the butter over medium heat. Add the minced garlic, Old Bay seasoning, smoked paprika, Cajun seasoning, and red pepper flakes. Stir and cook for about 1 minute until fragrant.
Build the Broth: Pour in the seafood broth, water, Worcestershire sauce, and hot sauce. Stir well and bring to a boil.
Cook the Vegetables: Add the diced potato and corn rounds. Reduce heat to a simmer and cook for about 10 minutes, or until the potatoes are tender.
Add the Seafood: Drop in the shrimp and crab legs (or mussels/clams). Simmer for another 5-7 minutes, just until the shrimp turns pink and the crab is heated through.
Cook the Noodles: Add the ramen noodles directly into the pot and cook according to package instructions (usually 2-3 minutes). If using cream, stir it in at this stage for a richer broth.
Garnish & Serve: Remove from heat and divide into bowls. Garnish with green onions, parsley, and a squeeze of fresh lemon juice. Enjoy immediately!
