Homemade overnight pizza dough needs to go through two rises: one at room temperature, and the second in the fridge. The first rise should only take 3 to 4 hours at room temperature until the dough has doubled in size. The time can vary depending on the temperature of the room. Check the dough after 1 ½ - 2 hours just in case! Pro tip: The oven (turned off) is a great place to wait for your dough to finish its first rise.
