Yes, you can prepare them ahead of time. There are 2 options: 1. Prepare the dough and then keep it in the fridge overnight (in a closed container or in a covered bowl). You can then shape, proof, and bake the dinner rolls the next day. 2. You can make the dough and shape the rolls, and then keep the tightly covered baking tin in the fridge overnight. The next day, bring the rolls to room temperature, proof until they double in size, and then bake them. I don’t recommend keeping the dough in the fridge for longer than one day.
