Yes, for example you can get an oven controller from Dbit (John Wilson, author
of Ersatz-11) to do that. I remember an article in a German ham radio magazine
that discusses the subject, and points out that it's trickier than you might
think. The reason is that toaster ovens are basically IR heaters, so the
temperature of the object depends on how much it absorbs. In the article there
was a suggestion to attach the thermistor used by the controller to a second
PCB similar to the one being reflowed, so it would sense a temperature close to
that of the real board.
