Hey Jack, what’s your favorite ATK recipe?

The Cook's Country Mashed Potato Casserole is a standard on my table during the holidays. My family loves mashed potatoes. But mashing the potatoes while everyone is celebrating is a thankless job. I mean, it's last-minute, right? I've done that before, and it's just sad for the cook.

It sort of feels like the perfect ATK recipe in the sense that we not only made it better, we made it simpler.

How would you describe this recipe to someone who’s never had it?

: This recipe captures what you love about mashed potatoes, but you make them a day in advance and enrich them with eggs. There's a little bit of Dijon mustard, there's chives, and you put them in a casserole dish. They go into the oven when the main protein comes out, and the casserole kind of soufflés a little bit, and the top gets little crispy brown bits. They’re sort of like mashed potatoes, but much better. And they're so much more practical for a busy holiday dinner prep.
