Is Apple Crisp Keto?
No, typical apple crisps are made with apples, flour, and sugar, so would not be considered keto.
What Is Keto Apple Crisp?
This is a keto mock apple crisp, meaning we make some swaps for the apples, flour, and sugar, to get all of the traditional warm and cozy apple flavors and textures, without all the carbs.
Why You’ll Love This Keto Apple Crisp Recipe

Low Carb Apple Crisp Ingredients
This section explains how to choose the best ingredients for this healthy apple crisp, what each one does in the recipe, and substitution options. For measurements, see the recipe card below.
For the filling:
- Gelatin powder – This helps to thicken the filling. Make sure you are using unflavored gelatin, with no sugar or other ingredients added! If you don’t have any gelatin, you can also thicken the filling by adding 1/4 to 1/2 teaspoon of xanthan gum instead. Make a slurry with a bit of water, then add to the filling while cooking.
- Lemon juice – Either bottled or fresh lemon juice will work.
- Butter – I prefer grass-fed for best flavor and nutrition, but you can use any unsalted butter. Coconut oil also works for a dairy-free option.
- Besti Brown Monk Fruit Allulose Blend – This keto, low carb, and sugar-free sweetener tastes and acts just like brown sugar. Two key characteristics that make it different from other brown sweeteners are that it dissolves like sugar and caramelizes like sugar, so I don’t recommend substituting it.
- Seasonings – Cinnamon, nutmeg, cardamom, sea salt, and vanilla extract. You could also use an apple pie seasoning in place of the cinnamon, nutmeg and cardamom, as that usually contains these.
- Zucchini – Our secret ingredient to replace the apples! I know it sounds odd, but once you cook it with spices, the flavor and texture is just like cooked apples. Yellow squash will work as well, which is what I used in my keto apple pie recipe.
For the keto apple crisp topping:
- Almonds – Use unsalted almonds; they can be roasted or unroasted. This is what provides the crunch! If you need a nut-free option, you can try pumpking or sunflower seeds, but their flavor is less mild than almonds.
- Besti Brown Monk Fruit Allulose Blend – See above for all the details and why I recommend this one in particular!
- Butter (or Coconut Oil) – The same unsalted kind you’re using for the filling.
- Seasonings – Vanilla extract, cinnamon, and sea salt
How To Make Keto Apple Crisp
This section shows how to make keto apple crisp with zucchini with step-by-step photos and details about the technique, to help you visualize it. For full instructions, including amounts and temperatures, see the recipe card below.
- Prep zucchini. Peel the zucchini and dice into 1/2 inch pieces.
- Bloom gelatin. In a small bowl, whisk together gelatin powder and lemon juice. Set aside to bloom.
- Bloom spices. Melt butter in a dutch oven and stir in Besti Brown sweetener, more lemon juice, cinnamon, nutmeg, cardamom, and sea salt.
- Thicken. When gelatin has thickened, whisk it into butter and spices in dutch oven.
- Cook squash. Add diced squash to the pan and bring to a gentle boil. Simmer for 30-60 minutes, until squash is very soft, most of the moisture has evaporated, and sauce starts to thicken. Stir in the vanilla extract and transfer mixture to an oval baking dish (this one is the perfect size!).
TIP: At this point, taste the zucchini mixture and look at the consistency. It should be very similar to apple pie filling!
- Make low carb apple crisp topping. Pulse almonds, Besti Brown sweetener, butter, vanilla, cinnamon, and sea salt in a food processor.
TIP: Be careful not to over-mix! You want to have a coarse texture, with lots of small almond pieces, as shown below.
- Bake. Crumble the almond topping over the mock apple filling, and bake until the filling is bubbly and topping is golden brown.
Storage Instructions
- To store: Store leftover keto apple crisp in the refrigerator, ideally covered in the same baking dish.
- To reheat: Reheat in a 350 degree F oven, or in transfer to bowls and heat in the microwave until warm.
- To freeze: You can freeze zucchini apple crisp for 2-3 months.

0Made this for dessert tonight and we all loved it! It was a big hit. Thank you for the recipe.
Freya Petersen
0Not like apple crisp at all. I wish when they’re trying to describe a recipe that they would not try to call it by a traditional name apple crisp is apple crisp and it does not have zucchini in it did not like it at all.
Tabania
0You know, I’m thinking hemp hearts instead of almonds. They are much lower in carbs and much higher in protein. I’d actually prefer ground flax seeds because I love the taste, but they are typically ground into a meal/flour. Any thoughts? Thanks for all you do.
Wholesome Yum D
0Hi Tabania, Yes, hemp hearts would work in this recipe to replace the almonds.
Jill
0Hi, I want to make this, but don’t have a food processor or blender, can I substitute almond meal for the chopped almonds?
Wholesome Yum D
0Hi Jill, My suggestion would be to purchase chopped almonds instead of almond meal. I believe this would give you the best results.
Jennifer Affinito
0This is an amazing recipe for a dessert using zucchini! I wouldn’t have known it was zucchini if I hadn’t baked it myself!
I give it 5 stars despite these tiny (and I mean tiny) items to note: I wasn’t too much a fan of the cardamom; I would probably use pumpkin pie spice next time (and there will be a next time!). It was just slightly liquidy at first, but probably because I didn’t give it a chance to cool down. The next day I heated some in the oven in a ramekin dish and it was perfect. I used Swerve, as I didn’t have Maya’s brand, and I was anxious to make it. p.s. easy peasy to make!
Carol
0This tastes amazing. So much so that my husband thought I used apples. The topping is nutty and satisfying. Just what I was craving! At least 10 friends have asked for the recipe!
JJ
0I can’t wait to try this on a fall day. Don’t have a food processor. What do you recommend to crush those almonds in that case?
Wholesome Yum D
0Hi JJ, If you have a blender that could be used instead of a food processor. If you do not have a blender put the almonds in a zip lock bag and crush them with something heavy like a rolling pin and then mix in a bowl with the Besti Brown sweetener, butter, vanilla, cinnamon, and sea salt.
Tre
0Hi, I’m not sure what I did wrong, but when I pulled the crisp out of the oven there was a large quantity of clear liquid under the topping. I reduced the squash/filling mixture for 60 minutes and it was thick before it went in the oven. It tastes good, but not sure why I had the clear liquid.
Wholesome Yum D
0Hi Tre, Sorry this recipe didn’t meet your expectations. Maybe next time try cooking the filling a little longer to fully evaporate any liquid. I am not exactly sure where a clear liquid would have been coming from.
Laura
0Made it. Love it. Next time going to try another reviewer suggestion to add in green apple extract, sounds good but was seriously good even without it. Topped it with your homemade whip cream.
Lisa Newman
0Great way to use up zucchini. I used one of the giant ones that got away and it was enough for the whole recipe. Since all ingredients are keto approved, I feel decadent digging in with a spoon for a snack.
Trudy
0The best zucchini for mock apple are those giant hard ones. The ones you don’t see to pick then suddenly you have a giant on your hands. Peel, cut into halves, then with a spoon scrape all the seeds and seed pith. You are left with half moon shape that you can slice into thin apple slices. They will be crunchier like apples instead of softer like zucchini. You can actually use these slices just like apples got pie or cobbler. Lemon juice is a must to mimic the tartness.
Stacy
0Haven’t made this yet but have everything ready to go! Is there anything I can substitute for gelatin (like agar maybe)? Thanks Maya! And btw, your donut recipes are the BEST
Wholesome Yum M
0Hi Stacy, Sure. Feel free to use agar agar in the recipe in place of the gelatin. Alternatively, you can also thicken the filling with 1/8 teaspoon of xanthan gum. This will prevent the filling from gelling but will thicken it to a nice consistency.
Joyce Morris
0Maya, you are ridiculously clever and innovative!! I can’t wait to try this and due to all of the amazing recipes that I have made from your website, I expect this one to be equally as fantastic!!!
Joyce Kostro
0Can’t wait to try this – just placed order for your brown sugar Bestii! Do you think apple extract would work in this to give it more apple flavor? I’ve been dying to try my extract as apple crisp is my favorite dessert but previous recipes I’ve tried with zucchini just didn’t have that flavor. If so – any recommendations on how much to use? Thanks!
Wholesome Yum M
0Hi Joyce, Yes, you can absolutely add apple extract to this recipe! Extracts can vary in strength by brand, so unfortunately I can’t give you an exact amount. Try adding a small amount to the filling and then adjust to taste before pouring into the baking dish for the final assembly. Best wishes!
Lynn
0I have made recipes similar, but use chayote squash instead with green apple extract. Tastes just like Granny Smith apples!
Toni
0This is such a perfect crisp recipe!! It’s healthy and delicious!!
Beth
0Oh wow! This crisp is so delicious and I can’t believe that it’s low carb too! My family and I are obsessed with this recipe.
Gale
0I wonder how walnuts or pecans would work?
Wholesome Yum M
0Hi Gale, Walnuts or pecans may become a bit soft in this recipe. If you are looking for a crunch in the topping, then I would stick with almonds. If you don’t mind a softer texture, then pecans or walnuts should work just fine. Enjoy!
Sam
0This was my first time using besti brown sweetner. It was so easy to use and perfect to satisfy my sweet cravings. I also love the hidden zucchini in there. This recipe is a win in my book.
