Directions

1. Preheat the oven to 350°F (175°C).
2. In a large saucepan over medium heat, whisk together the gelatin, 3 tablespoons lemon juice, and butter until smooth.
3. Add the sweetener, cinnamon, nutmeg, cardamom, and sea salt. Stir to combine.
4. Add the diced zucchini and the remaining 3 tablespoons of lemon juice. Cook for 20–25 minutes, stirring occasionally, until zucchini softens and takes on an apple-like texture. Stir in vanilla extract if using.
5. While the filling cooks, prepare the topping. In a food processor, pulse the almonds until chopped into small pieces (not powder). Add sweetener, melted butter, vanilla, cinnamon, and sea salt. Pulse until a crumbly mixture forms.
6. Transfer the zucchini filling to a baking dish and spread evenly. Sprinkle the almond topping over the filling.
7. Bake for 25–30 minutes, until the topping is golden brown and crisp.
8. Allow to cool slightly before serving.

FAQs

Why use zucchini instead of apples?

Zucchini has a similar texture to apples when cooked and absorbs the spices well, making it an excellent low-carb substitute.

Does the crisp actually taste like apples?

Yes, the combination of zucchini, lemon juice, and warm spices gives it a surprisingly authentic apple flavor.

Can I make this recipe nut-free?

Yes, substitute sunflower seeds or pumpkin seeds for the almonds in the topping.

What sweetener works best?

A brown sugar substitute like Besti Brown Monk Fruit Allulose Blend works best for a caramel-like flavor.

Do I need to peel the zucchini?

Yes, peeling helps achieve a more authentic apple-like texture and prevents a green tint in the filling.

Can I use other spices?

Absolutely, cloves or allspice can be added for extra warmth.

Is this dessert keto-friendly?

Yes, it’s made with low-carb sweeteners, zucchini, and nuts, keeping it within keto guidelines.

Can I prepare this ahead of time?

Yes, you can make the filling and topping separately a day in advance. Assemble and bake when ready to serve.

How do I know when it’s done baking?

The topping should be golden and crisp, while the filling should be bubbly around the edges.

Can I use a different thickener instead of gelatin?

Yes, xanthan gum or glucomannan can be used, but gelatin gives the best texture.
