McConaughey partnered with Operation BBQ Relief to deliver the turkey dinners to more than 20 local fire houses as part of its annual "With Thanks" campaign.
"Our initial reason for coming here was going to be to say thank you to the first responders that stopped the Woolsey Fire last year. But... another fire, quite a few, have come," he said.
The group also cooked an additional 800 dinners to deliver to homeless shelters in the area.
