Key ingredients for the best gluten-free apple pie recipe

These ingredients are the basics for the recipe, you will find the complete list with quantities in the recipe card at the end of the post.

GLUTEN-FREE FLOUR | I used a combination of fine almond flour and gluten-free oat flour, if making for someone with celiac, be sure your oats are certified gluten-free. You could easily use all almond flour or all GF oat flour too or a combination of GF AP Flour and almond, oat, and even coconut flour.

LIGHT BROWN SUGAR | I love that this brown sugar from Dixie Crystals is non-GMO!

ROLLED OATS | Again, be sure that they are certified gluten-free if making for someone sensitive, and not quick-cooking oats.

PECANS | leave out if desired, but they add a wonderful crunchy texture to the crust and crumble topping.

APPLES | Peel, core and thinly slice apples, see below for suggestions on the types of apples to use.

VANILLA | Try my homemade vanilla extract and if not gluten-free, try my bourbon vanilla extract recipe too!

SPICES | I opted to use Pumpkin Pie Spice, you can use Apple Pie Spice, or straight up cinnamon too!

How to make this easy gluten free apple pie

Step 1 | Making the GF Crumble Topping and Crust

In a large mixing bowl, combine GF Oat flour, Almond Flour, oats (not quick oats), ½ teaspoon salt and pecans. Finally, stir in melted butter until moistened and blended.

HINT: I like to mix crumble toppings with my hands, do not be afraid of getting your hands dirty.

Reserve 1 cup firmly packed crumb for the topping, tossing the balance of the gluten-free crust mixture into a well greased 9-inch deep-dish pie plate. Using your hands and the edge of a measuring cup, press the crust mixture in bottom and up sides of dish.

Step 2 | Assembling Gluten Free Apple Pie

Toss the sliced apples with cinnamon sugar, coating well. Layering the apples on the crust, however, if you don’t care about pretty layers, then just pour the apples into the crust, delicious either way!

Step 3 | Make sugar and cornstarch slurry

Combine cornstarch, sugar, kosher salt and vanilla in a small saucepan, stir in water. Whisking constantly over medium heat, heat mixture until it boils.

Pour the hot sugar syrup mixture over the top of the apples. Toss the reserved crumble topping into a small-medium bowl and toss about to loosen. Then grab a handful of the leftover crumble topping, crumbling evenly over the pie.

In preheated 375°F (190° C) oven, bake gluten-free apple crumble pie for 40-50 minutes, covering with foil 20 minutes into baking to avoid burning the crust and crumb topping.

Substitutions

Here are a few suggestions to make this pie for a variety of dietary restrictions:

NOT GLUTEN-FREE | Use 1 cup of all-purpose flour and 1 cup of oat flour because well oats! But you can use all regular flour if you choose.

VEGAN | Exchange the melted butter for plant-based melted butter or melted coconut oil.

Variations

Change up your apples!

• APPLES | The best apples for apple pie are; Honey Crisp and Granny Smith, but these others equally hold up as well; Gala, Pink Lady, Cripps Pink, Golden Delicious, Northern Spy, Jonagold, Braeburn, McIntosh, Pippin and Red Delicious.
• I used a combination of Honey Crisp and Fuji apples. If you want your pie to be a bit less sweet, use Granny Smith, but I would suggest using at least two apple varieties.
• TOPPING | Serve this pie warm or cold, it’s especially delicious with a scoop of vanilla ice cream and a little sprinkle of fresh nutmeg and cinnamon. It would also be delicious with a light drizzle of salted caramel.

Storage Tips

Allow your gluten-free apple pie to cool on a wire rack. If you can’t wait to dig in, it’s delicious warm, especially with a scoop of ice cream!

The pie pieces will hold their shape poorly if cut while warm. If clean slices are desired, cool completely, slice and if desired warm, pop in microwave for 30-45 seconds per slice.

Keep pie covered with plastic wrap or foil on the counter for up to two days, I have always wanted a pie carrier! Place in refrigerator for an additional two days to extend it’s life; that’s a total of 4 days!

How to freeze apple pie

Apple pie is best first baked and cooled completely; then, the leftover pie may be wrapped well in plastic wrap (twice or once with foil to prevent nasty freezer burn) for up to 3 months. Thaw frozen pie at room temperature for several hours or overnight in fridge.

How to freeze slices of apple pie

Place cooled individual slices of apple pie on a parchment-lined cookie sheet and freeze for 1-2 hours. Once firm, wrap well in plastic or foil, then place in a freezer baggie or air-tight container. storing up to 3 months. 

How to reheat apple pie (4 common methods)

I’ll show you four different methods to reheat apple pie, either the whole apple pie or pie slices.

# 1 How to reheat apple pie oven method (best method)

Whole Pie or Slice of Pie | The best way to warm leftover apple pie is to place the pie on a baking sheet or in an oven-safe dish, and cover loosely with aluminum foil. Place in preheated 350°F (175° C) oven and warm for 15-20 minutes for a 9-inch pie and 7-12 for an apple pie slice.

# 2 How to warm apple pie in a toaster oven

Since a toaster oven is similar to a regular oven, only smaller in size, the same technique applies, but your pie might warm quicker, so start checking at about 10 minutes. 

# 3 How to warm apple pie in an air fryer

Using an air fryer to reheat your apple pie is a great option! Since an air fryer uses hot air to circulate around the food, it will rewarm the pie quickly and evenly. And it doesn’t require turning on the oven! Either line air fryer basket with foil or parchment paper and lay a piece of foil over the top of the pie or slice of pie or loosely wrap apple pie in foil.

Place in prepared preheated 350° F (175° C) air fryer basket and fry 5-10 minutes. This method works best for 1-2 slices depending on the size of your air fryer. If you have a large air fryer that can hold a whole pie, proceed with above instructions air frying for 15-20 minutes, making sure it’s covered well with foil. If not warmed to your liking, air fry in 5 minute bursts until warmed.

#4 How to reheat apple pie in the microwave

This is the fastest, but my least favorite way to reheat apple pie. Microwaving the pie will results in a soggy crust and, ultimately, a soggy pie. For best results if you must reheat in the microwave. Place a slice of apple pie on a microwave-safe plate and cover it with a damp paper towel or splatter shield. Microwave on medium power in 30-second intervals, rotating  90° between each heating until warmed through.

How to reheat a frozen apple pie

First, please make sure that your pie is in an oven-safe dish. Second, remove any wrapping on the pie and place a piece of foil sealing it around the top edges. Warm the entire pie in a preheated 325° F (165° C) oven for 15-30 minutes. Checking at 20 minutes if warming through, then remove foil and continue to reheat for 5 additional minutes for a crispy crust. This works for a homemade pie as well as a store bought apple pie.

How do I know when my reheated apple pie is warmed through

To test for warmth, use a metal skewer or butter knife and stick into the center of the pie or slice; let it sit for 5-10 seconds; if it comes out warm or hot to the touch, your apple pie is ready. If still cool, return to heat source.
