Use a 13x9 pan that is 2 inches high for this pie, it will be full to the top before baking, so place it on a baking sheet in case any overflows. But mine did not overflow, I put it just in case and it makes it easier to remove the pie without having to grab the edge of the pan since the pie is really over the edge.

Peel, core, and slice apples. I used an apple corer peeler as it makes it really easy especially for 8 pounds of apple, but they can easily be done with a knife also)

Mix sour cream, sugar, salt, together

Lightly beat eggs and mix in vanilla

Pour egg mixture into sour cream mixture, then stir in flour.

Pour that combined mixture over the apple and stir them until they are fully coated.

Place filling into the pie crust.

Bake 400 degrees 15 minutes,

then adjust the temperature to 350 degrees and bake for 45 minutes

then add crumb topping bake at 375 degrees for 20 minutes

Total time (1hr20min)

This is one very large deep dish pie, great for a crowd or to have plenty left over otherwise.
