Ingredients:
- 1 cup (237 ml) vegetable oil
- 1 cup (125g) all-purpose flour
- 1 large yellow onion, chopped (approx. 1 1/2 cups)
- 1 large green bell pepper, chopped (approx. 1 cup)
- 3 celery stalks, chopped (approx. 1 cup)
- 4 cloves garlic, minced (approx. 1 tablespoon)
- 8 cups (1.9 L) chicken broth (low-sodium)
- 1 (14.5 oz) can diced tomatoes, undrained
- 1 pound (450g) Andouille sausage, sliced
- 2 teaspoons Cajun seasoning (such as Tony Chachere's)
- 1 teaspoon dried thyme
- 1/2 teaspoon dried oregano
- 1/4 teaspoon cayenne pepper (or more, to taste)
- 2 bay leaves
- Salt and black pepper to taste
- 1 pound (450g) medium shrimp, peeled and deveined
- 1 pound (450g) lump crab meat, picked over for shells
- Cooked white rice, for serving
- Chopped fresh parsley, for garnish
- Hot sauce, for serving (optional)
Instructions:
- In a large, heavy-bottomed pot, heat the vegetable oil over medium heat. Gradually whisk in the flour, stirring constantly. Reduce heat to medium-low and continue to cook, stirring constantly, until the roux is a deep, dark reddish-brown color (like chocolate). This can take 30-45 minutes.
- Add the chopped onion, bell pepper, and celery (the holy trinity) to the roux and cook, stirring frequently, until softened, about 8-10 minutes. Add the minced garlic and cook for another minute, until fragrant.
- Gradually pour in the chicken broth, stirring constantly to prevent lumps. Add the diced tomatoes, Andouille sausage, Cajun seasoning, thyme, oregano, cayenne pepper, and bay leaves. Bring to a simmer.
- Reduce heat to low, cover, and simmer for at least 1 hour, or up to 2 hours, stirring occasionally, to allow the flavors to meld.
- Increase heat to medium. Add the shrimp and crab meat. Cook until the shrimp are pink and opaque and the crab meat is heated through, about 5-7 minutes. Do not overcook!
- Remove bay leaves. Taste and adjust seasoning with salt and black pepper as needed.
- Serve hot over cooked white rice, garnished with chopped fresh parsley and a dash of hot sauce, if desired.
