Low Carb Apple Crisp


They say that you haven’t truly experienced fall if you haven’t had a slice of an apple crisp. It’s one of the season’s favorite comfort food, after all. But what if you’re cutting down on carbs and sugar? Can you no longer enjoy a warm slice of this fall favorite?

Our recipe has swapped out traditional flour for almond flour, creating a crispy topping that’s both gluten-free and low in carbs. To sweeten the deal, we’ve used monk fruit, a natural sweetener that won’t cause blood sugar spikes. A pinch of xanthan gum ensures the perfect texture, while a touch of salt brings all the flavors into balance.

Most notably, our version trades traditional flour for almond flour for a gluten-free topping and monk fruit to sweeten the deal. A pinch of xanthan gum makes the perfect texture and a touch of salt brings all the flavors into balance.

As you spoon the apple filling into your baking dish and scatter the almond flour crisp over the top, anticipation builds. And in just under 20 to 25 minutes in the oven, the moment of truth arrives—the crisp topping turns a glorious golden brown while the fragrant bubbles of the apple filling peeks through.

Whether planning a special gathering (Thanksgiving anyone?) or indulging alone, we’ve got you covered with this healthier keto apple crisp recipe! It has all that apple pie goodness without the high-carb crust and high-sugar filling. Grab your apron, preheat that oven, and ready yourself for this guilt-free slice of apple heaven.

Slice 4-5 apples.
If you want them peeled, peel the skin off first before slicing your apples. You may use a knife to cut them, or you may use an apple slicer. You may add more apples if you want your apple crisp to have more apple flavor, but note that it will increase the carb count.
Using a skillet, brown your butter for the apple filling.
You may use salted butter or unsalted butter. You should pour in your 4 fluid ounces of butter and let it cook for a while until it turns golden brown. Browning your butter will provide your apple crisp with a nutty and bold flavor.
Add the sliced apples, vanilla extract, Lakanto Monk Fruit Sweetener, and cinnamon into the skillet with the melted butter.
Stir the ingredients periodically.
Let the ingredients sit there for about 5-7 minutes, stirring periodically.
This will allow the apple slices to soften and the mixture to thicken. The sweetener and butter will eventually caramelize and become thick, which should give our apple filling a gooey texture.
Transfer the apple filling to a baking dish or clear pie plate.
Set aside for now as you make the crisp topping.
Preheat oven to 350 degrees Fahrenheit.
The next couple of steps would be us making the breading and top part of the apple crisp.
Using a skillet, brown your butter for the crumble.
You should pour in your 3 fluid ounces of butter. Cook it for a while until it turns golden brown. Make sure you don't cook it on high heat or you would burn it.
In a mixing bowl, pour in all the other ingredients for making the crisp topping.
Add in the almond flour, Lakanto Monk Fruit Sweetener, and xanthan gum. Add salt to taste.
Once the melted butter has turned golden brown, pour it into the mixing bowl with the other ingredients.
If you opted to not melt the butter, you can just directly add the butter cubes into the mixing bowl.
Mix all the ingredients until small clumps form.
Using a fork or spatula, gently mix your crisp topping ingredients. If you did not melt your butter, you can use your hands to directly mix the ingredients. Use your hands to smash the butter together with the other ingredients.
Add the crisp on top of the apple filling. Make sure to cover all the apples!
Put the baking dish in the preheated oven and let it bake for 20-25 minutes.
Remove the baking dish from the oven and let it cool for a while.
Be careful in whipping out a fork and jumping right in as your apple crisp is most certainly very hot. Just let it cool for a few minutes. Take a few pictures while waiting for it to cool down.



  • Vegetable or fruit peeler: Peeling you apples reduces the carb content of the final dish, consequently this recipe calls for peeled apples.
  • Mixing bowl: this is where you'll be mixing all the ingredients to make the apple crisp topping.
  • Baking dish or clear pie plate: this is where you'll be baking and serving your keto apple crisp. If you want it to have a pie shape, use a clear pie plate.

Misc Notes

  • You can make this apple crisp recipe dairy-free. Just replace the butter with coconut oil (melted) and you should be good to go. The ratio of coconut oil to butter is 1:1, so no need to adjust the proportions.
  • If you're allergic to nuts, you can replace almond flour with sunflower seed flour. It's low in carbs, high in protein, gluten-free, and most importantly, doesn't contain nuts. It also has a 1:1 ratio to almond flour.
  • For easier blending of the ingredients for the crisp topping, you can use a blender or food processor.
  • This low carb apple crisp recipe goes well with vanilla ice cream. Be sure to pick a gluten-free brand. You wouldn't want to ruin your low carb diet because of some random vanilla ice cream. So make sure to top off your low carb apple crisp with a keto vanilla ice cream.

Key Ingredients and Tools


The main ingredient of this low-carb dish. For this recipe, we’ll be using 4-5 whole apples, but you can use more if you want your apple crisp to have more of that tart apple flavor. You can have it peeled or unpeeled, depending on your preference. We recommend using Granny Smith apples as they’re known for their wonderful tart flavor, firm texture and fewest carbs.

Tip: the key to any great-tasting fruit pie is to use fresh fruit. To ensure that your keto apple crisp will turn out great and tasty, it’s recommended that you use fresh apples for your apple filling.

Lakanto Monkfruit Sweetener

As our brown sugar replacement, we’ll be using the ever-reliable Lakanto Monkfruit Sweetener. It’s our preferred keto-friendly sweetener as it is zero glycemic, is 100% natural, and doesn’t have an aftertaste. It also has a 1:1 ratio to sugar, making it easier to convert traditional apple crisp recipes into keto-friendly ones.

We’ll be using it for the apple filling and the crisp that goes on top.


Cinnamon is a spice commonly used in apple-based desserts, and it certainly fits our low-carb apple crisp recipe. Its warm and slightly sweet flavor will pair exceptionally with the natural sweetness of apples. It will also add a pleasant and aromatic taste to our apple crisp, enhancing its overall taste.

Cinnamon just has a natural affinity for apples. When paired together, they’ll create a classic and harmonious flavor combination that many people associate with fall. It will add that needed spice to our keto apple crisp.

Tip: you can substitute cinnamon with the aptly named apple pie spice if cinnamon doesn’t work for you. Nutmeg and ginger should work too.

Almond Flour

To create our crisp, we’ll be needing flour. Regular wheat flour and oats are out of the table as they are high in carbs, making them non-keto. That’s where almond flour comes in. Almond flour is a keto-friendly flour substitute that is entirely made from ground, blanched almonds. It’s perfect for making keto desserts such as our keto apple crisp.

As to which almond flour you should use, we recommend that you use blanched almond flour for the best results. It’s made from almonds with their skins removed. This results in a finer compared to regular almond flour or almond meal. The removal of almond skins also helps to minimize any potential bitter or nutty aftertaste.

Blanched almond flour will give our crisp topping a more delicate and crisp texture.

Xanthan Gum

Xantham gum is an ingredient commonly used in many food items such as salad dressings, fruit juices, ice cream, and many more. It’s gluten-free, which makes it perfect for our low-carb keto apple crisp recipe.

We’ll be using it to thicken our apple crisp topping, giving it a crumbly texture. Do note that it’s highly concentrated, so use it sparingly to avoid over-thickening the crisp topping. In this recipe, we’ll only be using 1/2 tsp of xanthan gum.

Frequently Asked Questions

I’m thinking of adding crushed pecans to the crisp topping. Will it work?

It sure would as well as give it a nice crunch! If you are doing so because you are fan of everything pecans, you are in luck as we have quite a few pecan flavored desserts to check out.

Can I store leftover apple crisp in the fridge?

I want to reheat my frozen apple crisp. Will it be okay to microwave it?
