With the show coming to a close, so many stars sent Rachael heartfelt messages.
But no one had us tearing up quite like Michelle Obama!
"I can't believe it's been 17 years since you started this show," says Michelle. "What an incredible run. I am so thankful for all the memories we've made together, from talking together during Barack's very first presidential campaign to getting our hands dirty harvesting vegetables in the White House garden, to donating all those meals to folks in need."
The former first lady added, "Thank you, Rachael, for always being down for a little adventure with me and for lifting all of us up with your energy, your infectious laugh, and those mouthwatering recipes."
