Step 1

Preheat your oven to 375.

Step 2

Place the crust on a lightly floured surface, and roll out slightly so it expands about 1/2 an inch.

Step 3

Put the crust into a large deep pie plate, trim edges, and set aside.

Step 4

Peel, core, and thinly slice your apples. Sprinkle the lemon juice over the apples, and stir to distribute.

Step 5

In a separate bowl, combine 1/3 cup brown sugar, the flour, cinnamon, and nutmeg. Sprinkle over the apples and stir to evenly coat.

Step 6

Dump the apples into the pie crust, and shake it a little bit to make sure they settle into the pie plate a bit.

Step 7

Using your hands, mix together all of the streusel ingredients. Sprinkle over the pie, leaving in marble-sized chunks.

Step 8

Bake in a pre-heated oven for about 45 minutes. If the crust starts to brown too much, cover with foil. You'll know it is done when the apple mixture is bubbling and the topping is golden brown.
