Covering the Camembert when baking is not necessary, but it can be done depending on your preference. Baking the Camembert without a cover allows it to develop a lovely golden crust on top while the cheese inside becomes soft and gooey. However, if you want to control the level of browning or prevent excessive crust formation, you can cover the Camembert loosely with aluminum foil during baking. This helps to retain moisture and promotes even melting. Just remember to remove the foil towards the end of baking to achieve the desired texture and color.
