Preheat the oven to 350°. Remove the tart shell from the fridge and line with parchment paper. Fill the shell with beans or pie weights and bake for 15 minutes. After 15 minutes, remove the weights and paper and bake for another 20 minutes, uncovered, or until the bottom is golden brown. If the edges are browning too fast, cover them in aluminum foil and continue baking. Once the shell is browned, remove from the oven and cool completely before filling.
