Apple Crisp Ingredients
You need simple baking ingredients for this Apple Crisp. Together, they create a tender fruit layer and a crisp, crumbly topping.
Ingredients for the Apple Filling
Use 8 Granny Smith apples, 1/3 cup maple syrup, 2 tablespoons arrowroot flour or cornstarch, 1 tablespoon fresh lemon juice, 1 teaspoon vanilla extract, and 1 teaspoon ground cinnamon.
Ingredients for the Oat Crumble Topping
For the topping, use 1 cup almond flour, 1/2 cup coconut sugar, 1/2 teaspoon cinnamon, 1/4 teaspoon kosher salt, 1/2 cup cold cubed unsalted butter, and 1 cup old-fashioned rolled oats.
Best Apples for Apple Crisp
Granny Smith apples work especially well because their tart flavor balances the sweet topping. Also, their firm texture helps the slices hold their shape as they bake.
Ingredient Substitutions and Variations
You can swap cornstarch for arrowroot flour. Likewise, regular flour can replace almond flour, while another granulated sugar can replace coconut sugar.
Also, quick-cooking oats work when rolled oats are unavailable. For a dairy-free Apple Crisp, use vegan butter. Alternatively, use ghee if you tolerate it.
How to Make Apple Crisp
First, preheat your oven to 350°F (180°C). Then, grab a 9 x 13-inch baking dish and two mixing bowls.
Prepare the Apples
Peel, core, and slice all 8 apples. Try to keep the slices fairly even so they cook at a similar rate.
Make the Apple Filling
Next, toss the apples with maple syrup, arrowroot flour, lemon juice, vanilla, and cinnamon. Stir until the mixture coats every slice.
Make the Oat Crumble Topping
Meanwhile, combine the almond flour, coconut sugar, cinnamon, and salt. Then, work in the cold butter with a pastry cutter or fork until crumbs form.
Next, stir in the rolled oats. Keep some larger buttery crumbs because they add great texture.
Assemble the Apple Crisp
Spread the apple mixture evenly in your baking dish. Then, scatter the oat mixture across the apples without pressing it down.
Bake Until Golden and Tender
Bake the Apple Crisp for 45 to 50 minutes. The topping should look golden, while the apples should feel tender when you test them with a knife.

Tips for the Best Apple Crisp
A few small details make a noticeable difference. In particular, focus on apple texture, cold butter, and baking time.
Keep the Apples Tender Without Making Them Mushy
Choose firm Granny Smith apples and slice them evenly. Also, start checking the fruit near the 45-minute mark so it stays tender instead of turning overly soft.
How to Get a Crisp, Crumbly Topping
Keep your butter cold until you mix the topping. Then, work it into the flour just until you get coarse crumbs.
Also, avoid packing the topping tightly over the fruit. A loose layer gives the oats more room to brown.
How to Tell When Apple Crisp Is Done
Look for a golden topping and tender apples. In addition, you should see bubbling juices around the edges of the baking dish.
Make-Ahead Tips for Thanksgiving
Thanksgiving oven space gets crowded quickly. Fortunately, you can handle part of this Apple Crisp ahead of time.
Prepare the Topping Ahead of Time
Mix the topping ahead, then place it in an airtight container in the refrigerator. As a result, you can assemble the dessert faster when you need it.
When to Slice and Assemble the Apples
Slice the apples shortly before assembly. This keeps browning to a minimum and helps preserve their fresh texture.
What to Serve With Apple Crisp
Serve Apple Crisp warm with a scoop of vanilla ice cream. The cold, creamy ice cream melts into the cinnamon-maple juices, which makes every spoonful extra comforting.
Alternatively, add whipped cream or pour warm custard over each serving. For more recipe ideas and kitchen inspiration, you can also follow Kai Recipes on Pinterest and Kai Recipes on Facebook.
How to Store and Reheat Apple Crisp
This dessert stores well, so those Thanksgiving leftovers can become a very welcome treat the next day.
Refrigerating Leftover Apple Crisp
Cover leftovers or place them in an airtight container. Then, refrigerate them for 4 to 5 days.
How to Freeze Apple Crisp
First, cool the Apple Crisp fully. Next, place it in a freezer-safe container and freeze it for up to 3 months.
However, freezing can soften the topping and change the apple texture slightly.
The Best Way to Reheat Apple Crisp
Reheat the crisp at 350°F (180°C) for 10 to 15 minutes. This method helps bring back some crunch.
Alternatively, microwave individual servings in 30-second intervals until hot.
