The stand-up has appeared on several such shows in the past two years, including Would I Lie To You, You Have Been Watching, 8 Out Of 10 Cats and Mock The Week.
Asked if the popular format had a negative effect on the UK comedy landscape, Walsh told DS: "I can only speak for myself, and I really enjoy doing panel shows. I love writing jokes and I love the fact that you can't rely on your old material - you have to come up with new stuff.
"I quite enjoy watching them. There are stand-up shows, but they're usually tried and tested people, and I think panel shows are quite a good way of showcasing new comedians.
"On Mock The Week they've had Seann Walsh and Andi Osho, who are really good new people coming through, and I think it's really good to have that opportunity to do it."
"She added: "When you do TV stuff you have to be really good, but the way to learn how to deal with that kind of thing is just by doing it. It's a really good way of starting off. Sean Lock is amazing - he's amazing anyway - but he's also done it a lot and that's how he's leant to do it.
"I just really enjoy doing them and having the opportunity to learn how it all works and how TV is made. And being on a team of six people or whatever, you get that experience without it being just you for half an hour."
Walsh's Popcorn Comedy night returns to the Edinburgh Festival this month with several shows at the Pleasance Dome.
