Add ingredients, set the heat, and let it cook for four to five hours. This longer cooking time frees you up for other tasks, and reheating it is as simple as hitting a button.
Use a slow cooker pot large enough to hold everything. A standard five to six-quart cooker typically accommodates about six servings, while larger seafood may need a larger pot.
To avoid overcooked seafood or undercooked potatoes, layer ingredients inside the slow cooker: potatoes first, then corn, andouille sausage slices, garlic, and seasonings.
