There are many substitutes for baking paper. In addition to the already mentioned alternatives in the form of permanent baking paper, you can also fall back on tried and tested methods. For example, greaseproof paper can also be used as baking paper.
If you want a more environmentally conscious alternative, uncoated baking paper is suitable if you grease it with vegetable fat or similar before baking. Of course, you can also do without the paper altogether if you grease the tin while baking. If you then sprinkle flour, breadcrumbs or similar on the greased surface, bread, cakes and biscuits are easier to remove after baking.
An alternative would be baking trays made of glass. The advantage of these is that the contents adhere less to the glass and do not burn in. The trays are also easier to clean.
If you want a baking paper substitute for pizza, pizza lovers have the option of replacing the baking paper with a pizza or bread baking stone. These can also withstand higher temperatures and can be reused.
