He appeared in all 12 games and starting nine. He led the Irish defensive line and ranked sixth on team with 46 tackles, recorded second-most tackles for loss on team with seven and his two and a half sacks ranked third, also added one forced fumble and one fumble recovery. In 2010, under new defensive coordinator Bob Diaco, he made the switch from defensive tackle to defensive end in the new 3-4 defense. He started all 13 games in 2010, one of 11 players to start all 13 games for the Irish.

Prior to the 2012 season, Lewis-Moore was named one of Notre Dame's four captains. "He called my name last and I wasn’t really expecting it because we have a lot of guys on the team that are worthy of being captains," Lewis-Moore recalled. "To hear my name was really something special. I got a little teary eyed. I knew this season was going to be special but to be captain is just something I can’t really explain. It’s speechless." He started all 13 games for the Irish, but tore his ACL in his right knee in the first half of the 2013 BCS National Championship Game against Alabama. He finished his season with 40 tackles, including eight and a half for loss and six sacks, while forcing two fumbles.
