Gluten-free Walnut Apple Crisp


Last Updated on October 2, 2020

gluten-free apple crisp

Nothing screams fall like a warm apple crisp! It’s one of my favorite desserts to throw together because its delicious, and so easy to make. This gluten-free apple crisp has chunks of walnuts in the crumble, and goes perfectly with some vanilla ice cream.

I originally made this recipe last fall with spelt flour, but wanted to make it 100% gluten-free to accommodate those with sensitivities. You get a mix of warm, cinnamon baked apples topped with a walnut oat crumble- it truly doesn’t get better!

It’s one of those desserts that are perfect for a small gathering, or just a little something to keep in the fridge for that post-dinner sweet tooth.

I love prepping mine in a large pie dish, but making these into individual servings would be such a fun idea for a dinner party!

  1. Added 2 cups of frozen rhubarb. Absolutely delicious! No need for extra sugar as the apples provide that!!

  2. Hi, can this recipe be made and then frozen for later use ?

  3. I made this for Thanksgiving and it was a hit! I cooked it for the allotted time, but my apples were a bit crunchy, so I’d recommend cooking it for 10ish extra minutes! (Maybe it was the apples I used– I used envy for this recipe)

    • I also used oat flour instead of tapioca and it tasted great!

      • Hey Cal, I’m so happy to hear it was a hit! Good to note about the extra baking time. It’ll always vary depending on how thin or small the apples are chopped or sliced 🙂

  4. Made this for Thanksgiving and served with dairy-free vanilla ice cream. It was a big hit with everyone! An awesome tasting dessert, did not miss all the extra sugar in normal desserts.. and SOOO easy to make!

  5. This was amazing! I also left out the walnuts. I topped mine with some dairy free ice cream. . .YUM

  6. This is so good! Can’t believe what the tapioca does to the apples! Do not skip that step! I had to skip the walnuts because of kids allergies but it’s still delicious

    • I’m so happy you enjoyed it, Miryam!

      • Claire Jacobsen

        Soooo delicious and so easy to make. Is it important to store this in the refrigerator? Or can I leave it covered on the counter?

        • Since the apples are perishable, I would highly recommend refrigeration. I haven’t tested it on the counter, but wouldn’t keep it past 5 days if you try that!

    • I just wanted to update that this worked out amazing . When I took it out of the freezer I let it sit out for a few hours then baked uncovered . It was amazing as usual!
