Parve Food Cooked Alongside Meat
Does one have to wait before eating milchigs if one ate a parve food cooked in an oven with meat uncovered with liquid?
I assume you mean in the same oven as meat being cooked uncovered, but in a separate pan. The minhag to wait in between meat and milk applies only to instances where there is actual presence of meat in the food eaten. This is extended by the poskim to a “tavshil shel basar” such as a meat soup, even if one consumes the soup without meat. Any other transfer of meaty flavor would not require waiting before milk. This includes cooking parve in a [clean] meaty pot, even one used within 24 hours. In fact, R’ Elyashiv is quoted as saying that even consuming an onion cut with a meaty knife would not require waiting before eating dairy.
