This Chicken and Sausage Gumbo is a Louisiana inspired dish made with juicy chicken thighs, smoky andouille sausage, the holy trinity of veggies, and a flavorful dark roux. The roux is started in the oven, and finished in a large Dutch oven on the stovetop. The result is a cajun classic that gives you the very best flavors of the bayou in an hour.
