Baking Rolls in a Meat Oven to Eat with Dairy

Is it permissible to bake pareve rolls in a meat oven used the same day, in order to eat them with dairy products?

Permissible. Provided that the baking tray is disposable or lined with baking paper.

In the Talmud, Pesachim 76, there is a dispute between Rav and Levi whether aroma is significant or not, and similarly, the early authorities dispute how to rule. However, the Rema in Yoreh De'ah, Siman 108, writes that in the case of steam, one should be concerned about using a meat oven after pareve, but in the case of aroma, which is dry without food moisture, there is no need to be concerned. From the discussions there, it follows that in bread, certainly, there is no need to be concerned about steam, and therefore it is permissible. Even on the same day, as the Shach writes in Yoreh De'ah, Siman 108, S.K. 12, in the name of the Responsa Maimonides: "But in this case, there is no need to be concerned, as no aroma and saturation for the vessel is found that will return and emit into the food, even if the vessel is used on the same day, only if it does not touch directly." If it touches directly the tray, it is nat bar nat, which is forbidden to do initially in order to eat with the opposite type.
