Classics are classic for a reason. Sweet and crumbly, our cleaner gluten free Apple Crisp is a fall dessert mainstay you can feel really good about coming back to again and again. Spiced apples bake until tender in a buttery, maple glaze under a canopy of crunchy nuts and whole-grain oats. Naturally gluten-free, it’s a dish best served warm. With vanilla ice cream. In a very large bowl.

I’ve extolled the virtues of the galette (a.k.a. lazy lady pie) many a time, but in all honesty, there’s an even lazier “pie” out there, and that, my friends, is “the crisp.”
Spiced, soft apples topped with crisp streusel – seriously, what’s NOT to love?
Well, if you’re gluten free, there’s the flour. And if you’re trying to curb your kids’ sugar intake (ahem) there’s that too.

A Healthier Twist on a Classic
Yes, there’s a different – arguably better?!? – way to do it.
Healthy. Apple. Crisp.
Less butter, if that’s your thing. Fewer refined sugars. And completely gluten free.
While traditional crumb topping usually consists of butter, sugar and flour, this cleaner apple crisp uses oats and nuts to create a sweet, hearty celebration of cozy, fall goodness that you can feel pretty darn good about.
As if you needed another excuse to go apple picking…
How to Make Healthy Apple Crisp
Apple crisp is one the easiest dessert recipes, and I promise anyone can master it!
- Make the topping. Combine oats, pecans, walnuts, and brown sugar (or coconut sugar) in a food processor, and pulse until coarse. Add cold butter, and pulse until just incorporate. Place the topping in the fridge while you make the filling.
- Sauté the apples. Sauté diced apples in butter until they release their juices and soften slightly.
- Add the sweetener and thickener. Whisk maple syrup, cornstarch, vanilla, cinnamon and nutmeg, then pour into the apples. Simmer until the sauce thickens (it only takes a minute or two).
- Prepare the crisp. Scrape the apples into a casserole dish, then sprinkle evenly over the filling.
- Bake the crisp. Bake in a 350°F oven until the topping is golden brown and the apples are bubbling around the edges.
- Serve. Serve warm with vanilla ice cream.
Tips for Making This Recipe Perfectly
- Double-check your oats and make sure they’re gluten free.
- Oat selection matters – use old-fashioned oats, not quick cooking or steel cut.
- Mind your nuts too! Don’t use salted nuts (i.e. for snacking) and there’s no need to pre-toast.
- Dice the apples small (about 1″). Leave the peel intact if you prefer.
What Kind of Apples Should I Use?
An apple is an apple is an apple? Not so fast. There is such a thing as baking apples.
Select apples that are more tart than sweet (they’ll still taste apple-y after being sweetened with brown sugar) and are firm so they hold up well to baking. We used Honeycrisp in this recipe. Granny Smith, Pink Lady, Jonagold, and Braeburn are also all great baking apples.

- 1 tbsp cornstarch
- 1 tsp vanilla extract
- 1 tsp cinnamon
- ½ tsp nutmeg
- 1 tbsp lemon juice

Instructions
- Position a rack in the center of the oven and heat to 350°F. Spray a 9×13” casserole dish with cooking spray.
