The halachot of an oven are much more lenient that one of a dish, since there is no contact between the food and the oven. The real issues are regarding the oven tray which touches the food or dish and transmits taste - and possibly any recent projections of (non-kosher) food on the walls.

R Yitzchok Yaakov Fuchs (in his book Hakashrut, p. 665) writes Baking ovens and toaster ovens that were used for meat and dairy foods and even for prohibited foods may be used to bake or warm up kosher food on the condition that the food placed inside is wrapped hermetically in two wrappings. In any event only kosher baking tins or disposable ...

The question of rare and raw meat has been asked on this site before. There is some discussion among the Rishonim based on the mishna Beitza 3:3 about whether raw meat can be consumed, but their point of argument revolves around whether the meat must be salted first to remove the blood.

Lechatchila (before the fact) it is not permitted to cook in the same oven and at the same time meat and milk dishes (see SA YD 108:1). A key issue is one of steam (zeiah, for details see here and there) which carries meat/milk flavor into other dishes. Indeed no opinion permits cooking open milk and meat dishes together in the same oven. As such the ...
