This gluten free apple crisp is the one recipe I keep coming back to every fall, cinnamon-spiced apples under a golden almond-oat topping that actually stays crispy. One 9×13 dish, 75 minutes, and your kitchen smells like autumn.

This recipe has two back-to-back bake times, cold butter that must go in unmelted, and an almond trick that sets the topping apart from every other crisp you’ve made.

What Makes This Gluten Free Apple Crisp Different
Most apple crisp recipes pile the topping straight onto raw apples and hope for the best. The result is a topping that steams rather than crisps, and apples that are either underdone in the center or mushy at the edges. After making this a dozen times, I found that a quick 25-minute par-bake with foil on top changes everything. The apples soften evenly and build up a little liquid base, and by the time the topping goes on, it has nothing to absorb, just hot, dry heat to turn it golden.
The other detail that sets this apart is sliced almonds in the topping. They add a layer of crunch that oats alone can’t match, and they toast to a deep golden brown in the oven that looks genuinely impressive. You can swap in pecans or walnuts and get the same effect.
Ingredients You Need
For the filling, you need 10 apples, granulated sugar, kosher salt, cinnamon, nutmeg, lemon juice, and cornstarch for the topping: gluten-free rolled oats, gluten-free measure-for-measure flour, brown sugar, granulated sugar, vanilla extract, cinnamon, salt, cold butter, and sliced almonds.
A word on the apples: pick a firm variety that holds its shape under heat. Granny Smith is my first choice every time; the tartness balances the sweetness of the brown sugar topping. Honeycrisp, Pink Lady, and Golden Delicious are all solid options. Avoid anything labeled “best for eating” on the bag; those get mushy fast.
For the crumble to behave correctly, the butter must go in cold and cubed, not softened or melted. Cold butter creates pockets of fat that turn into the crispy clusters you want. Softened butter will give you a dense, greasy paste instead.
The flour acts as a binder. Pretty much any gluten-free 1:1 baking blend works here, just avoid single-flour options like almond flour or coconut flour on their own, as they change the texture significantly.
According to the USDA Fruit Guide, apples are one of the most fiber-rich fruits you can bake with, contributing significantly to the 9g of fiber per serving in this recipe.
Substitutions and Variations

| Ingredient | Substitute | Notes |
|---|---|---|
| Butter | Vegan butter or coconut oil | Makes it dairy-free; coconut oil gives a slightly different flavor |
| Sliced almonds | Pecans or walnuts | Both toast beautifully; roughly chop if whole |
| Brown sugar | Coconut sugar | Use the same amount; topping will be slightly darker |
| Cornstarch | Arrowroot powder | Use a 1:1 swap; thickens the apple juices the same way |
| Gluten-free flour | Almond meal | Works in a pinch; topping will be slightly denser |

How to Make Gluten Free Apple Crisp (Step by Step)
[STEP-BY-STEP PROCESS IMAGE PLACEHOLDER]
Make the apple filling. Preheat the oven to 400°F. Peel and chop 8 apples into 1/2-inch cubes, then grate the remaining 2 on a box grater. The grated apples dissolve into the filling as it bakes, creating a natural sauce around the chunks.
In a large bowl, combine all the apples with the sugar, salt, cinnamon, and nutmeg. Stir the lemon juice and cornstarch together in a small bowl, pour that over the apples, and toss until everything is evenly coated. The lemon juice brightens the flavor, and the cornstarch thickens the juices as they release.
Pour the apple mixture into a 9×13 baking dish, cover tightly with foil, and bake for 25 minutes. You want the apples just starting to soften; they’ll finish cooking when the topping goes on.
Make the topping. While the apples are in the oven, add 3/4 cup of the oats to a food processor along with the gluten-free flour, both sugars, vanilla, cinnamon, and salt. Pulse 5 times until just combined.
Add the cold butter pieces and half the almonds. Process for about 30 seconds until the mixture forms crumbly clusters. Add the remaining oats and almonds and pulse 2 more times. If needed, remove the blade and press some of the mixture into larger chunks with your fingers; bigger clusters stay crispy after baking.
What surprised me the first time I made this was how quickly it comes together in the food processor. It takes less time than making it by hand and produces a more consistent texture.
Bake the crisp. Scatter the topping evenly over the par-baked apples. Bake uncovered for 20 to 25 minutes, until the top is golden and the edges are visibly bubbling. Let it cool for at least 15 minutes before serving; the filling needs that time to set up slightly.
In my experience, 22 minutes hits the sweet spot for this recipe. At 20 minutes, the topping is done but pale; at 25, it can tip over into too dark on the edges. Start checking at 22 and pull it when you see a deep golden color across the surface.

Make-Ahead, Storage, and Reheating
This crisp is one of the better desserts for making ahead. Par-bake the apple filling, let it cool completely, then wrap the dish tightly. Make the topping and store it in an airtight container. Both keep in the fridge for up to 2 days. When you’re ready to bake, top and bake as written; the total time is the same.
Leftovers keep in the fridge for up to a week. To reheat, bake at 350°F for 20 to 30 minutes, loosely covered with foil if the top starts to darken. I’ve personally found that reheating in the oven is far better than the microwave; the topping gets crispy again instead of turning soft.
To freeze, let the baked crisp cool completely, wrap it in plastic wrap and then foil, and freeze for up to 3 months. Thaw overnight in the fridge before reheating.
What to Serve With This Apple Crisp
A scoop of vanilla ice cream is the classic pairing, and the contrast between the cold cream and warm crisp is hard to beat. vanilla ice cream alternatives. Whipped cream is a lighter option that works just as well.
For a richer dessert, a drizzle of caramel sauce over the top adds another layer of sweetness that complements the almond topping. fall dessert recipes, You can also serve it plain; the filling is saucy enough that it doesn’t need anything extra.
If you’re serving this at a gathering, it holds well at room temperature for a couple of hours and can be loosely tented with foil to keep it warm. easy Thanksgiving desserts
