I typically freeze my apple pie filling in 3 cup portions which is enough for me to make a homemade pie. You may want to freeze yours in smaller or larger portions. I always use up all of my frozen apple pie filling within 4 to 6 months freezing it. In my personal opinion, homemade frozen apple pie filling is a HECK of a lot better than canned!
Peel and core apples, cut apples into wedges. Place all apple wedges into a large mixing bowl. Sprinkle lemon juice, ground cinnamon and granulated sugar on top. Gently stir mixture until well blended. Spoon mixture into quart sized freezer bags. Purge out the air, zip shut. Label outside of bags.
When ready to use, remove from freezer and thaw at room temperature for about 10 minutes. Then spoon your apple pie filling into an unbaked pie crust and bake.
