Which vegetable replaces carrot in the Cajun version of French mirepoix?

Bell pepper replaces carrot in the Cajun version of French mirepoix. The resulting mixture of onion, celery, and bell pepper is known in Cajun and Louisiana Creole cooking as the holy trinity.

Traditional French mirepoix generally combines onion, carrot, and celery. When Acadian settlers adapted French cooking traditions in Louisiana, carrots were less practical or accessible in many local kitchens, while bell peppers grew well and were widely available. The substitution suited Louisiana’s climate and became part of the region’s distinctive flavor profile.

Cooks usually chop the three vegetables and soften them in oil, butter, lard, or another cooking fat. This aromatic base supports the deeper flavors of roux, stock, seafood, sausage, poultry, and game in dishes such as gumbo, étouffée, and jambalaya.

Garlic is a frequent addition, but it does not replace bell pepper in the defining three-part mixture. Sofrito may also include bell pepper, but it is a different culinary tradition and often includes garlic and tomato.
