I made this for as an entree for Mum's birthday dinner on the weekend, and it was absolutely devoured by my family. Really enjoyed exploring a new way of cooking with zucchini.

We absolutely loved the result. My 10 y.o. son had an absolute success cooking this dish! He decided to add a little bit of feta cheese on top for color and taste.

Awesome! I made this with Pasta. I tossed out excessive oil from the pan and used the oil from the tomatoes for the pasta. I Just tossed it a couple of times. Very delicious!

Bernardo M.

One of the first recipe tries. Successfully achieved amazing flavor and had a lot of fun preparing it! Thank you Chef Keller!


Ok, why does salting like that not make the food overly salty? The water leaves it, the density increases, the salt remains - so how is it not too salty?

Finally made this after watching the video 3 times and reading the workbook. Damn, it does not disappoint. Here’s the pic. It looked and tasted as good as advertised. And my first time making a concasse and vierge,no less.

All these degrees are in Fahrenheit I believe. Could you show or say it in Celsius as well?

Any suggestions on what other vegetables to roast like this other than squash or eggplant?

Lindy F.

Absolutely delicious, and definitely a keeper. My husband loved the zucchini prepared like this so much that he even ate the stems without realizing. I hate fresh parsley, so I used fresh basil in the vierge really does scream summer! I can see that pairing so well with fish, chicken, and lots of other veggies.

Is it me or the zucchini teleport themselves from the bottom to the top floor of the oven ... ;-)
