When she's not performing, Nicola enjoys creating in the kitchen. When asked about her "creative outlets" by Who What Wear in December 2020, Nicola said, "I have been doing a lot of cooking, and it was a thing I couldn't do for months on Bridgerton because we travelled so much making the show and you are eating on set a lot. I love to cook; I find it really therapeutic. I cook for my mom, and she is like Gordon Ramsey telling me whether the food is good or bad."
As you might recall, she also appeared in The Great British Baking Show holiday special. "Baking is not so much my thing because the stress of that tent never leaves you," she joked, "but cooking I'm good with."
