You are already on a tripod, with most of the action happening at a (relatively) fixed distance, so no autofocus is needed. Go to manual focus, focus up on area where most of the action occurs, stop down the aperture, and you are good to go. Assuming you are aimed at a stovetop from about 6 feet distance, I would stop down to at least f/8. That will keep a range of about 4 feet in focus (i.e. 4 feet from the camera to 8 feet from the camera.) If you stop down to f/11 you will get about 6 feet of sharp area.
If you are curious to calculate what a different f/stop will give you, use a DOF calculator like this: Depth of Field (DoF) calculator | PhotoPills
If you need to shoot "inserts" or closeups where the camera and subject are at radically different distance than before, just manually focus for the inserts.
Pro video shooters never bother with auto focus. The hunting is annoying and difficult to predict. Better to focus on what you need, keep the action within the zone your focussed on, stop down to get the DOF you require, and for different angles and distances simply re-focus.
