This turned out pretty well. I chopped the onion instead of slicing it. I suggest dicing the zucchini, rather than slicing to make it cook faster and also easier to puree with a hand mixer. I didn't have any creole seasoning so I used Old Bay. And I didn't know what chicken or fish base was so I used some Veggie bouillon paste. That worked pretty well. I also used 1/2 half and half and 1/2 skim milk. Tasted just fine. Oh, and I loved the tarragon! Really aromatic and made the kitchen smell good as everything cooked. And it tasted great. We'll make this again for sure -- and will continue to tweak it till it's perfect for us. Thanks so much for sharing!
Great flavor. I only pureed half the vegetables. It is an excellent fish stew.
