I am skilled enough to ruin this.
Oooh, aaaah!!!
Wow!
What type of tater did you use on top? Not baking? Russet? Yellow? Idaho?
I’m making these!!!!!!! Wow!
Slick!
Chef john !! Yey you've not popped up on my feed in ages … dang youtube… great to see you … but where is the cayenne
Chef John- my mother introduced me to you a few years ago, and we would binge your videos when we hanged out. She passed last year, and your familiar voice and cadence remind me of her. ❤
Yum yum, I too will make these, with prime rib
Q: “Mashed or au gratin?“
A: “Yes.”
Yum
And you can even leave out the mash! 😃
Yes please 😋😋👏👏👏👏👏❤❤❤❤❤
That’s a lot of carbs.
Why not both👈🏻😜!
Gratin is what Chef's call the baking dish.
Annoying voice.
This is GENIUS!!! It's so wonderful to see your video again. We have missed you ❤
450 for an hour? The smoke alarms are going to go off!
I don’t cook to try and impress people, but it looks delicious.
Are the potatoes on top parboiled?
What a great way to reuse leftover mashed potatoes and make something so satisfying.
No!!!!
😮😊😊👩🏿🍳💋
Are the sliced potatoes on top cooked or raw?
Wow what a great variation. So you must have a French name for this? They/it looks great. Your mash looks extremely white, what spuds are you using?
Good Lord.
It's under the sauce
Delish!
Ain't nothing lowkey about that.
Oh my goodness! ❤
What do you mean by more cheese? When did you put on a first application of cheese?
I think I can feel myself gain weight just watching Chef John's videos.
….but…. but why wouldn't you incorporate the pepper and salt into the bottom mixture of mashed taters? weird, dude…
😋 lol
Where is the cayenne???
If you put that in a 450-degree oven for an hour with that cheese on it, it'll be blacker than midnight when you take it out.
I cannot stand his voice cadence
°C as well as °F would be much better.
I'm going to make this with panko bread crumbs
