Step 1

Thaw flounder and shrimp, if frozen. Rinse the flounder and the shrimp; pat dry with paper towels. Cut the flounder into bite-size pieces. Set the seafood aside. Cook onion and garlic in hot oil in a large pot over medium heat for 12 to 15 minutes or until onion is tender. Turn down heat as needed to prevent the onion from overbrowning.

Step 2

Stir in tomatoes, broth, water, potatoes, Creole seasoning, red pepper, and hot pepper sauce. Bring to boiling; reduce heat. Simmer, covered, for 15 to 20 minutes or until the potatoes are just tender.

Step 3

Meanwhile, beat cream cheese in medium bowl with an electric mixer on medium to high speed until smooth. Gradually beat in milk on low speed until mixture is very smooth.

Step 4

Add the cream cheese mixture, the flounder, the shrimp, and corn to soup. Return to boiling; reduce heat. Simmer, uncovered, for 3 to 5 minutes or until the shrimp are opaque. To serve, ladle chowder into bowls.
