Keto Apple Crisp with Zucchini (Gluten-free, Vegan)

Keto apple crisp with zucchini makes a wonderful autumn treat for any time of day! Apples and zucchini are flavored with vanilla and cinnamon, topped with a pecan-coconut crumble, then baked until warm and bubbly. This healthy apple crisp is a delicious breakfast, snack, or dessert topped with your favorite keto-friendly ice cream.

Zucchini is a wonder vegetable, isn't it? You can enjoy it as veggie tots or sneak it into sweets (like these keto chocolate zucchini muffins and keto zucchini bread), shred it or slice it or even toss it with cinnamon and sweetener and call it faux apples! Well, that last one has always been trickier for me. I know a lot of keto apple recipes out there require all zucchini or squash as an apple replacement but... I just can't.

An apple is an apple and zucchini will never be that.

But here's the great thing. Zucchini is so neutral and you can mix it with a higher-carb ingredient- like apples!- to bring the carb/sugar count down a tad. I've used this trick in my low-carb zucchini gratin with sweet potatoes and my keto apple cake. 😉

It works so well in this keto and gluten-free apple crisp. Equal parts apple and zucchini lowers the natural sugars in the dish so it can still be enjoyed by those on a low-carb, keto or modified keto diet, but those irresistible, seasonal flavors of apple and cinnamon still shine. 🙂

why you'll love this apple zucchini crisp

• it's a low-carb and keto apple crisp recipe that comes together easily
• the ingredient list (and prep time) is short

the ingredients

To make this keto apple crisp, you will need:

• Apples and zucchini. The real MVPs of this dish. Any kind of apples will do. Peel them and slice them about ¼" thick. Choose medium zucchinis and slice them the same thickness, then cut them in half again so they're moon-shaped.
• Monk fruit sweetener. I prefer Lakanto's Brown Sweetener for both the filling and the topping, but you can also use their Golden sweetener (affiliate- use code STEMANDSPOON for 15% discount on Lakanto products).
• Arrowroot powder. This helps thicken the filling, don't skip it! It's especially necessary with this recipe since zucchini releases water as it cooks. For a substitute, you can use ½ teaspoon xanthan gum instead of arrowroot.
• Spices. Cinnamon is used in both the filling and the topping. You'll also need salt, nutmeg, and allspice (optional).
• Pecan pieces, coconut flakes and almond flour. These combine to make the apple zucchini "crisp" topping. Use blanched almond flour and raw pecan pieces.
• Coconut oil. For the topping. If you prefer to use butter, feel free to substitute! It should be softened or even slightly melted.
• Vanilla and maple flavor. Vanilla extract is used in the filling and topping. The maple flavor is a nice touch for the topping but is completely optional.

how to make keto apple crisp

This keto apple crisp recipe is so simple and the topping is surprisingly easy and good. It has a crunchy kind of texture that resembles a true crisp made with oatmeal, but it's a completely grain-free and gluten-free apple crisp.

1. Make the filling. Peel and slice the apples and zucchini, then toss them with the arrowroot powder, lemon juice, sweetener, vanilla, cinnamon and salt. Pour into a 8x8" baking dish.
2. Prepare the low-carb apple crisp topping. In a food processor or blender, blitz together the pecan pieces and coconut flakes. Combine them with the remaining topping ingredients- the almond flour, sweetener, spices, coconut oil, vanilla extract and maple flavor, if using. Stir well, the mixture should hold together.
3. Bake the keto apple crisp. Crumble the topping over the apples/zucchini. Bake until the top is golden brown. Cool, then enjoy!

tips for the best results

For the best apple zucchini crisp, keep this in mind:

• The pecan and coconut should be the size of large crumbs. Don't blitz them any longer than a few seconds, in fact, just a few pulses will do. If you don't have a food processor or blender, roughly chop the coconut flakes and pecan pieces really small.
• Cover the top of the crisp with a sheet of parchment paper or aluminum foil after the first 20 minutes of baking. This will prevent the top from browning too much.
• Once the crisp is done baking, let it cool for at least 10 minutes. The juices will thicken as it cools and will thicken even more when the crisp is refrigerated.
• Store this low-carb apple zucchini crisp covered in the fridge for up to 7 days. To reheat, pop it in the oven at 300°F for 10-20 minutes or until it is warm.

This keto apple zucchini crisp recipe makes a delicious and healthy treat that works for breakfast, snack, dessert, you name it. It's a wonderful changing-of-the seasons recipe and a yummy way to make use of autumn apples.
