The delicious keto apple dessert is a simple and easy way to enjoy the crunchy, sweet flavor of apples on a low-carb diet. It's also a tasty way to get in your daily does of vegetables.

If you are trying to get your family to eat more veggies, this treat is a great way to do it. They may not even be able to tell you didn't use real granny smith apples or fuji apples in the mock apple filling.

Ingredients

You only need a few basic ingredients and a little time to make this low carb apple crisp recipe. In fact, you may already have everything you need right in the kitchen!

Mock Apple Mixture

For the low-carb apple pie crisp filling, you'll need the following:

• zucchini
• lemon juice
• keto sugar substitute
• cinnamon
• nutmeg

You can also add a keto-friendly thickener like xanthan gum to make a thicker filling and apple extract for a stronger apple flavor.

Apple Crisp Topping

I use a nutty topping for the zucchini apple crisp. It’s just a blend of these ingredients:

• Chopped pecans
• Almond flour
• Oat fiber or coconut flour
• Granulated keto sweetener
• Cinnamon
• Melted butter

Quick Tips

• Keep the zucchini slices at least a quarter inch thick. If you cut them too thin, the squash will get soft and mushy when cooked.
• Use a coarse almond flour. Low carb baked goods are generally better with fine almond flour, but for an apple crisp, a coarser grind works best. You can even use almond meal with the skin still on.
• Add apple extract. The lemon juice provides a fruity taste to the zucchini but you'll get a more believable taste if you add in a little apple flavoring.
• Use a ball shaped squash. There are round ball varieties of zucchini that you can grow yourself. The shape and size is more like an apple.

Instructions

To make the recipe, simply prepare the zucchini mixture then add the crumb topping. Then simply bake it in the oven. That's it!

Before using the zucchini, it needs to be peeled and sliced in half lengthwise. Then the seeds need to be removed using a spoon to scrape them out.

Cut the zucchini into half moon slices to look like apple slices. The summer squash pie filling will look just like apples!

Once the zucchini is sliced, it’s mixed with lemon juice, cinnamon, nutmeg, sweetener and optional apple extract. Then it’s poured into a baking dish.

Combine the dry ingredients in a mixing bowl. Then cut in the butter using a pastry cutter until the mixture is crumbly.

Sprinkle the topping over the filling and baked until the zucchini is tender. It takes about 45 to 50 minutes to cook completely.

Serving Suggestions

This keto zucchini apple crisp is perfect served warm or cold. When warm, it tastes great with a scoop of keto vanilla ice cream on top. Topping off with some whipped cream is also a great option.

Variations

It’s easy to modify this recipe into a keto mock apple pie. Just add my almond flour crust or coconut flour crust and bake in a pie pan. You’ll end up with a low carb Dutch apple pie!

If you’d rather have a traditional apple pie, add a top crust too.
