Peel, core and slice apples into a salt water soak. About 2 teaspoon salt dissolved in 1 quart water. This will prevent browning apples.
When all apples are sliced let them soak about 5 minutes and drain well.
Place apples in your pie plate to be sure you have the right amount. Pack them in and mound them up. I like lots of apples in my apple pie!
Remove these apples to a bowl, add sugar cinnamon mixture and mix to coat. ½ cup sugar, ½ tsp. cinnamon, 3 Tbsp flour, Dash of salt
Lay an oversized piece of foil in your pie plate. You want enough to wrap around all of the apple filling.
Put the apples back into your foil lined pie plate. Include all the sugar mixture. Wrap the foil sides up and around the pie filling. If needed add another layer of foil to be sure it is all covered.
Place the pie plate and contents in the freezer and allow to freeze.
When it is frozen take the foil wrapped pie filling out of the pie plate and place in freezer bag or wrap in freezer paper.
Remove air, seal, and label. Put back in the freezer for later baking.
Baking the Pie
Preheat oven to 450 degrees F (Do this before you take your pie out of the freezer. You are cooking the pie filling from frozen.)
Make your crust. Unwrap your frozen pie filling and place it in the bottom crust, add 2T butter spread across the top. (just scatter some pieces)
Add top crust, pinch down edges to seal and cut some slits in the top.
Cover just the the top of the pie with foil to prevent over browning.
Bake for 15 minutes at 450. Turn temperature down to 375 degrees and bake for another 15 minutes.
Remove foil and finish baking (45-50 minutes)
When the pie is bubbly and the crust is brown, it’s done.
Notes
Tips for making the frozen apple pie filling.When you are mixing the pie filling ingredients, it is mostly to taste. You can use more or less of the sugar mixture, add more cinnamon or less, you might like nutmeg instead or in addition. I don't suggest changing the flour content, this amount thickens the pie as it bakes. Don't skip the salt! It really adds nice flavor.Tips for BakingThe same baking instructions can be used if you are baking a whole frozen pie or just adding frozen filling to a fresh pie crust. While it is baking, watch the edges of your crust, if it looks like it might get too browned, you can cover the edges of the crust with a pie ring or some foil.
