Crockpot: This soup can be made in a Crockpot. Cook for 2-3 hours on high and then follow the steps for the roux before adding to the Crockpot. Broth: I have used Better Than Bullion base to make broth. It is just easier to keep at hand for all my cooking.Pressure Cooker: This recipe was created in a 6qt Instant Pot DUO60 Multi-use Pressure Cooker.
