foil containers with cardboard lids in oven?

Using foil containers with cardboard lids in the oven is generally not recommended. Here are some key points to consider:

1. Heat Resistance: Cardboard can catch fire at high temperatures, typically around 400°F (204°C). Check the manufacturer's guidelines for the specific temperature limits.


2. Steam and Moisture: If the food generates steam, the cardboard lid may absorb moisture, compromising its integrity and potentially causing it to warp or disintegrate.


3. Alternatives: If you need to cover your dish, consider using aluminum foil instead of a cardboard lid. Aluminum foil can withstand higher temperatures and is safe for oven use.


4. Use Caution: If you do decide to use a cardboard lid, keep the oven temperature low and monitor it closely to avoid any fire hazards.
