Hmmm I have never used those. I too always make my own crusts. I find serving size of most store bought food very odd. When I am too busy to make my own crusts, hubby will buy the pie crust mix in a box. I hate those... it's newbie unfriendly (hubby still needs my help) also the mix in the box is too much for a single crust but not enough for both top and bottom. So if I use it for both I will have paper thin pie crusts. If I use it for single crust I have extra to throw away.

Simple answer....don't use those crusts.
You can make your own and freeze them.
I can honestly say I have never used a store bought pie crust...either premade or from a box...always always make my own.
If you have a food processor....it's so easy!

If you're determined to use those crusts - make less filling. Most pie plates are deeper than the premade crust pie plates.

I've seen those crusts and they always looked small to me, more like an 8" than a 9" crust. I usually have a package or two of the Pillsbury Refrigerated Crusts in the freezer, they are very good. But I agree with lindac, it's really easy to make a pie crust in the food processor. I usually keep a few sticks of butter in the freezer and grate them for the shortening, works great.

If you plan on continuing to use those pie crusts, you might want to consider keeping some of those little frozen tartlet crusts on hand. You could use up the extra filling in those.
