How do I adjust a recipe for a 9 inch pipe into a 10 inch pipe in

Hello, I see many recipes that I would like to try. They are mainly geared towards a 9 inch pie pan. I actually only have four metal 10 inch pans and I live in a place in Mexico where I cannot just run down to the store and buy a 9 inch pan, also they are quite expensive to have it shipped here. How would I adjust the recipe and then also the baking time for the larger size do I need to turn the temperature up or would I just bake a little longer? Thank you so much any help is greatly appreciated .

Happy Baker

A 9" pie pan is about 1.25x the size of an 8" pie pan. I'd recommend increasing the recipe by 25%, and you might have to bake a little longer, but be aware that metal pie pans will cook your crust faster than ceramic or Pyrex, so if blind baking, you'll probably want to check on it sooner than you would otherwise.

Thanks Emmie for posting this, as I see (oops) I got the translations wanted by the original poster backwards. I was reading it down from 10" to 9", and posted wanted to go up.

Alice Medrich here has an article (May 2022) on how to use one pan to bake any recipe.
Also there are charts showing the volumes in standard baking pans - pie, round, rectangle, tube, etc - so you can convert a recipe. For example, one for two 10 inch pies to three 9 inch pies. King Arthur Flour, joy of baking other sites.

Last PS - there may be info around on converting times, but the volume in a 9 " and a 10" pie plate (if the same depth or height) will likely be similar, but a bit less for the smaller one.
So start checking the pie(s) about 3/4 of the way into the recommended baking time and remove from the oven when they show usual signs of being done - color of crust, doneness of filling (if it's a single crust pie and you can see it).
