Is Apple Crisp Keto?

No, typical apple crisps are made with apples, flour, and sugar, so would not be considered keto. This is a keto mock apple crisp, or mock apple crumble. That means 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.

Ingredients & Substitutions

Here I explain the best ingredients for this keto apple crisp, what each one does in the recipe, and substitution options. For measurements, see the recipe card.

Mock Apple 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, or you can try chayote squash.

Keto Apple Crisp Topping:

Almonds – Use unsalted almonds; they can be roasted or unroasted. This is what provides the crunch! You can also substitute pecans or walnuts here, but they turn out softer and a little less crunchy. If you need a nut-free option, you can try pumpkin 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.

What To Serve With Keto Apple Crisp

This low carb apple crisp dessert is delicious on its own, but a scoop of vanilla ice cream never hurt. Here’s how to keep it keto: It should be very similar to apple pie filling! If it’s very watery, you may need to cook it for a bit longer. You want to have a coarse texture, with lots of small almond pieces, as shown below.
