Yes, I would absolutely prebake the crust. To do that, put your crust in and crimp as you normally would. Then take a piece of parchment paper, crumple it up in a ball, then uncrumple and smooth it out and put in on top of the crust so it covers completely. Fill it with pie weights, dry beans, or dry rice. Bake at 350 for about 15 minutes, preferably on a lower shelf in the oven. Take it out of the oven, remove the paper and weights, and put it back in for another 8-10 minutes until it gets just a hint of color on the edges. Remove from oven, and let it cool a bit. Proceed with your recipe.
