- Step 3: Pour in 4 cups chicken broth and 1 cup diced tomatoes. Add 1 tsp dried thyme, 1 tsp paprika, 1/2 tsp cayenne pepper, and 2 bay leaves. Cover and cook on low for 6 hours.
- Step 4: During the last 30 minutes, add 1 lb peeled and deveined shrimp and 1 cup lump crab meat to the gumbo. Stir gently and cook until shrimp are pink and cooked through.
- Step 5: Remove bay leaves and stir in 1 tsp file powder if using. Serve gumbo hot over 1 cup cooked white rice per serving.
