Step-by-Step Instructions
Sauté the Aromatics:
Heat the olive oil in a large Dutch oven or heavy-bottomed pot over medium heat. Add the finely chopped onion and thinly sliced fennel. Sauté until they are softened and beautifully translucent, about 5 to 7 minutes.
Bloom the Spices:
Stir in the minced garlic, smoked paprika, and crushed red pepper flakes. Let this cook for about 1 minute until the spices become incredibly fragrant.
Deglaze the Pot:
Pour in the dry white wine, using a wooden spoon to scrape up any delicious browned bits from the bottom of the pot. Allow the wine to simmer until the liquid is reduced by half, which usually takes about 3 minutes.
Build the Broth:
Pour in the crushed tomatoes and the seafood broth. Season generously with salt and black pepper to taste. Bring the mixture to a rolling boil, then immediately reduce the heat to low. Cover the pot and let the broth simmer gently for 15 minutes. This crucial step allows the flavors to meld together perfectly.
Simmer the Fish:
Gently tuck the 2-inch chunks of firm white fish into the hot, simmering broth. Let the fish cook for 3 minutes.
Add Shrimp and Mussels:
Add the prepared shrimp and mussels directly into the pot. Cover the Dutch oven and continue to cook for another 4 to 5 minutes. You’ll know it’s ready when the shrimp turn a bright, opaque pink and all the mussels have opened up. (Note: Be sure to immediately discard any mussels that do not open).
Garnish and Serve:
Remove the pot from the heat. Carefully give the broth a taste and adjust the salt and pepper if needed. Sprinkle the freshly chopped parsley over the top and serve immediately while piping hot!
