Louisiana andouille is a coarsely ground, heavily smoked pork sausage seasoned with garlic, red pepper flakes, and black pepper. It is smoked low and slow over pecan or hickory wood for up to 8 hours. The result is a sausage with an assertive, almost chewy texture and a deep, complex smoke flavor that permeates everything it cooks with.
Kielbasa is a Polish smoked sausage that is finely ground, more lightly smoked, and seasoned with marjoram and garlic. It has a softer texture and a milder, more approachable flavor. It is an excellent sausage, but it is not andouille.
Why the Difference Matters in Cooking
In a gumbo, andouille breaks down slightly during the long simmer, releasing fat and smoke flavor into the broth. Kielbasa, being more finely ground and less heavily smoked, does not do this in the same way. A gumbo made with kielbasa will taste like a stew with sausage in it. A gumbo made with real andouille will taste like a gumbo.
Where to Find Real Andouille
In Louisiana, andouille from the Cajun town of LaPlace -- yes, the same Laplace -- is considered the gold standard. Jacob's World Famous Andouille ships nationally and is widely regarded as the benchmark. Several online retailers now ship authentic Louisiana andouille overnight. It is worth the cost and effort for any important Cajun dish.
