Keto Apple Crisp (With a Secret Ingredient!)

This Keto Apple Crisp is something that the whole family will love! For our keto version of an apple crisp, we replace the apples with zucchini. I know! This might sound a little crazy, but it works. In fact, I’ve been able to successfully fool people into thinking that this was a traditional apple crisp with apples. 


It is important to peel the zucchini and cut it lengthwise in half to scoop out the seeds. These steps will result in the zucchini to resemble the color and texture of an apple. 

Lemon Juice

This is the most important ingredient / step in this recipe. Once the zucchini has the seeds removed, is peeled and diced, the next important step is to cook the zucchini in a saucepan with lemon juice. The lemon juice is so important in this recipe because it gives the zucchini the acidity that mimics an apple. Zucchini also releases a lot of water during the cooking process. So once the zucchini is done simmering with the lemon juice, strain all of the liquid. 



For the recipe we use a very small amount of unsweetened apple sauce to add the apple flavor to the dish. We’ve seen other recipes use apple extract for flavoring but these ingredients can be hard to find. Unsweetened applesauce is inexpensive and easily found in most grocery stores. It is still very high in carbohydrates so it’s important to not add too much. We only add two tablespoons for the entire dish which equals only 1.3g of net carbs
At first when developing this recipe, we first tried to add a small amount of diced apple to the dish (mixed in with the zucchini). While the filling tasted good and had the apple flavor that we are looking for, the addition of apples threw off the texture. Unsweetened applesauce keeps the texture of the dish in tact and adds the apple flavor. 

Maple Extract

This ingredient is optional, however we like to add this to the dish because maple extract combined with sweetener resembles the flavor of brown sugar which is commonly used in an apple crumble. 



For our keto crumble we use a combination of chopped pecans and almond flour. These keto-friendly ingredients pair so nicely with the cinnamon and apple flavors. 


You can of course eat this dish alone, but like any good crumble this is best served with a side of keto whipping cream or a small amount of store bought keto-friendly ice cream
