Combining classic Creole seasonings and a fragrant roux, this streamlined stew delivers the flavors of the famous seafood jambalaya served in New Orleans. Substitute any mild, white fish for the cod, such as monkfish, rockfish, or halibut. Add clams or crawfish or even a bit of spicy sausage. Or serve as is with crusty bread and a fruity white wine.
Preheat oven to 350 degrees.
Heat oil in a large heavy-bottomed soup pot or Dutch oven over medium heat. Slowly stir in flour with a wooden spoon. Cook mixture 10 to 15 minutes, stirring occasionally, until it turns the color of milk chocolate. Add onion, bell peppers, and celery to pot and cook, stirring, for 5 to 7 minutes until vegetables are softened. Add garlic, paprika, thyme, bay leaf, and cayenne and cook for 2 more minutes. Add tomatoes, water, and chicken broth and bring to a boil. Stir in rice, cover pot tightly with a lid or foil, and place in preheated oven. Bake for 25 minutes.
Season fish with salt and pepper to taste. Remove pot from oven and add fish to pot, making sure that the pieces are completely submerged in cooking liquid. Cover and return to oven for 5 to 7 more minutes, just until fish is cooked through. Stir in sliced green onions and chopped parsley just before serving.
