It has been a very worthwhile experience. I have perfected poached eggs for the first time. I can’t wait to show my son who loves to cook. I’m visiting him in a couple of weeks and I’m packing my workbook to share with him. Thank you Chef Keller. You are an inspiration to life and to food.

I loved this class. Instead of focusing on specific recipes, the primary focus is on technique. The information is great as is the manner in which it is delivered.

Appreciate the cooks and the food arts much more.

To understand that I share the same passion for food as Thomas Keller is an eye-opener! It's been long commented from family and friends that I'm at my happiest in my kitchen-now, I am at the beginning again with new tools and many more to come!

Hello Chef Keller, Not sure if you read these communications or if they are passed along. I know you are a busy chef. But the number one reason I signed up for MasterClass is to be educated by you. I love your teaching methods and passion for your art. EXCEPTIONALLY INSPIRING! My passion is cooking and baking, and I have done well on the personal side of competing at local and some national brand contests. But I always wanted to go to culinary school, but didn’t have the time or funds for it as I had to put the needs of family first. Signing up for MasterClass and learning from you, gives me a foundation. It was a gift that I gave myself. Learning so much from your sessions and I am truly grateful. So may techniques that you share and I agree that quality and practice, practice, practice are essential. Respectfully, Patricia

I loved this lesson, because it showed me how elevated and delicious zucchini can be. I have a new-found love of cooked zucchini now. I made a meat sauce to serve with it, and a combination Sauce Vierge and Pomodoro to serve over it. It was a hit! Thank you, Chef Keller!

My zucchini turned out very soggy. What did I do wrong? I could barely transfer them from the pan to the plate because they fell apart like they had disintegrated. Did anyone else have this outcome? They were nice and brown. Maybe it was too much oil or too much moisture? I let them sit out 15 minutes after scoring but prior to cooking because they were releasing a lot of water and I wiped all that off. If anyone has any tips, I would appreciate it. I'd like to try again.

Loved this technique. No tomatoes so topped mine with the roasted garlic, toasted bread crumbs and mint. Delicious!

I think I over caramelized before roasting the zucchinis, but it was delicious! loved this technique, can't wait to use again. The sauce vierge would go with a lot of things

Absolutely fantastic! I just made this recipe and it tasted amazing. Such a soft, creamy and partly almost crunchy Zucchini. The tomato concassé is a perfect companion. This will become one of my favorites.


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.

Matteo A.

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!
