Apple Walnut Pie is a fresh take on your favorite dessert, All-American old fashioned apple pie. Made with Granny Smith apples and tons of chopped walnuts, Apple Walnut Pie is the perfect patriotic apple dessert.
Pre-heat your oven to 350 degrees. Wash, peel and core your apples. Slice them about 1/4 inch thick. You don't want them too thin so that they won't still hold their crunch but not too thick that they won't cook through. Add them into a large mixing bowl and set aside for a couple of minutes.
Prepare your crust (homemade or store bought) and add the bottom crust to your pie pan. Poke holes in the crust bottom with a fork and then beat together two egg whites and brush them on the bottom of the crust to prevent sogginess when baking.
In a saucepan over medium heat, melt your butter. Add in your flour and whisk together until if forms a loose paste. Add to this the spices, water and both sugars and continue whisking until the sugar dissolves and everything is incorporated. Add in your apple slices and stir to combine until all of your apples are lightly coated in the sauce and continue stirring until your apples are slightly cooked, about 5 minutes. You don't want them too soggy but you want them a bit tender. Remove from the heat and pour into your prepared pie crust. Stir in your walnuts.
Remove from the heat and pour into your prepared pie crust. Add the crust top to your Apple Walnut Pie and crimp the top and bottom together. Make a few slices in the top of the pie crust and lightly brush the entire pie crust with the egg white. Place your Apple Walnut Pie on a sheet pan in case of sauce overflow and bake in your oven for 40 minutes. Remove Apple Walnut Pie and let sit out to cool completely before cutting.
