Heat the oil in a large pot or Dutch oven over medium-high heat.
Add the onion, celery, carrots and Creole seasoning. Stir and cook until all of the vegetables start to soften, about 5 minutes.
Add the garlic, stir, and cook another minute.
Add the broth, water, black pepper, and the bay leaf. Stir and bring to a boil. Reduce to a simmer and let simmer, uncovered, for 35 minutes. Season with more pepper and some salt as desired.
Add the pasta and let simmer another 10 minutes until cooked.
Serve with hot fresh-baked French bread.
Notes
You can add more broth in place of the water for a richer soup.
