The 'Glee' star is forced to spend a lot of time away from his partner, 26-year-old model Renee Puente, because of work commitments.
But when they get together they love to spend some quality time in the kitchen putting their culinary skills to the test.
He told Bang Showbiz: "Sometimes she does [join me], she works a lot too so. We make sure we make that time [together].
"Our favourite thing to do is cook together, we cook at least three nights a week so just make food, make love and have a great time together."
When he's not in the kitchen or working, Matthew, 34, likes to get away on vacation; and his favourite destination is Hawaii.
He said: "I'm a big, big fan of Hawaii, it's where I tend to go for vacations. Just because, from California, it's not that bad to fly over."
However, Matthew also has a fondness for Europe.
The actor - who has just released his new album 'Where It All Began' and performed on Thursday night in London - said: "I think Barcelona is one of my favourite cities. I love that city so much. I come to London about three or four times a year so I love it.
"It depends on what I'm in the mood for. Sometimes I'm in the mood for sightseeing and history, and then sometimes I just want to sit on a beach and chill out and have a drink!"
