Ahead of her final appearance, Lakshmi sent a message to her fans on social media.
“What a ride,” she wrote. “Tonight is the finale of season 20, but for yours truly it will also be the final finale of my tenure on Top Chef. I want to thank everyone who has reached out to me this week and expressed so much love…”
Lakshmi added: “It’s humbling and I’m honored by every handshake, hug, selfie and compliment I accept on behalf of not just me but my whole crew.
She then issued a promise to former Top Chef contestants, stating: “To all the Top Chef contestants far and wide: please know I am always rooting for you from my corner of the world.
“I will still be here for you long after Top Chef is gone, just as I have been after each of your seasons has ended.”
Speaking on the episode as the winner was crowned, Lakshmi said: ”A lot of us grew up on this show. It’s been a long ride. Twenty Seasons is quite an accomplishment.”
