Then, learn to make the stocks and sauces that are essentials in Chef Keller’s restaurant kitchens.


Students give MasterClass an average rating of 4.7 out of 5 stars.

Between both of Chef Keller's two master classes; I believe I have vastly enriched my culinary skills, knowledge, and abilities- specifically in fundamental execution of master international technique and broad range of options and self- culinary expression. He is an OUTSTANDING instructor, facilitative coach and mentor.

Sorry, I am very bad in English. I just would like to thank chef Keller. I am very sad the classes are finished. I really hope to see him again.

Thank you ever so much, what an enjoyable and enlightening series!

The first real MasterClass in this website... I have been browsing others but are more like documental... i.e. Leibovitz

The lesson is ok. Interesting. Slow cooking is great for lots of things. But for prime rib I also need some drippings. How else can you make Yorkshire pudding? And there are some in my family who will fight over the almost crispy ends from cooking for a bit at a higher temp.

I don’t understand, he says to air dry in fridge overnight but then uses an unsalted roast?

And if im kinda scared to burn my house, would it also taste the same good if i didn't use the torch?

I bought an incredible new oven and am getting to know it. Followed Chef Keller’s guidance and the roast came out almost perfect - only human error got in the way. Slow roasting is the way to go and the Pureed Potatoes are like crack!!

Does using the blow torch just as it is deliver better results than using a Searzall?

A fellow student

Thomas Keller explaining slow cooking with yellow goggles while casually blowtorching a rib roast has a surreal quality to it.

A normal blow torch will blow out when you invert it because the liquid runs down the tube. There is a flexible hose they sell for a bernzomatic blow torch to go between the bottle and the head. So you can keep the bottle below the head and aim the blowtorch head at any angle. I use a blowtorch a lot when searing meat cooked sous vide.

Margaret E.

without a torch, can't you do the same thing searing on a grill, then bring into oven?

A fellow student

Made this tonight, the torch was a nice way to sear it and the meat turned out amazing. Especially the bones! Nice and simple, but absolutely delicious

Beautiful prime rib! I've noticed in several lessons Chef will touch the protein, then dip his fingers in his salt bowl without washing. Is it just me or should contamination be a concern?
