Zucchini is sort of like tofu and eggplant. It can stand alone and be great, or you can do a bunch of sneaky cooking things to it and transform it into something else. With a little bit of sensory science magic, we’ll turn the humble zucchini into your favorite apple (zucchini) crisp.

here’s what you’ll need

To turn our zucchini into an apple-tasting dessert, we’ll be using everything you’d find in a traditional apple crisp. It’s an interesting combo, and it works! 

  • Zucchini: This recipe requires a lot of zucchini, about 6 cups. Look for medium-sized zucchini that’s about 7-8″ long. 
  • Sugars: To sweeten this dessert, we’re using both white sugar and brown sugar.
  • Lemon Juice: To add a tangy zest, include ⅓ cup of lemon juice.
  • Dry Ingredients: All-purpose flour and rolled oats form the base for our crumble topping. A bit of salt helps amplify the sweet flavors.
  • Cinnamon: This helps to trick your brain into thinking that the zucchini is an apple since cinnamon is so synonymous with apples.
  • Butter: Use butter to bind together the crumble topping. Make sure it’s cold and cubed.

Go Vegan

To make this crisp vegan, you only need to use vegan butter. Everything else is already vegan-friendly!

making it is simple

The most important part of this zucchini mock apple crisp is cooking the zucchini pieces with sugar for a delicious, sweet flavor.

Step 1: Cook the Zucchini
Preheat the oven to 350ºF (176ºC). Peel and chop the zucchini into bite-sized pieces. In an uncovered saucepan, bring the zucchini, sugar, and lemon juice to a simmer over medium heat. Cook the zucchini for about 15 to 20 minutes until it becomes soft and tastes sweet.

Step 2: Create the Crumble
Mix the flour, oats, brown sugar, cinnamon, and salt together in a large bowl. Add cubes of cold butter to the flour mixture and blend with your hands until everything is evenly distributed. The dough will be very crumbly. Sprinkle it over the zucchini mixture.

Step 3: Bake
Bake for 30 to 45 minutes, or until the juices are bubbly and the top is golden brown.

Make It ahead

You can, but zucchini has such a high moisture content that I’d recommend only making it 1 day in advance. Keep the crisp topping separate and top right before baking.

The acidity of the lemon juice turns the chlorophyll in the zucchini to an olive green color. But despite this color, when you close your eyes and take a bite, this crisp legitimately tastes like apple crisp!

Notes

Storage: Leftover crisp can be stored for up to 4 days in the fridge covered or in an air-tight container. You can also freeze the baked version for up to 3 months. Reheat it in the oven from frozen. Just be sure to cover it with foil to prevent burning.

    I tried this recipe because I had a huge zucchini . Had to cook about 40 minutes to get soft . Also used gluten free brown sugar . End result . It was delicious .

    My family has been making this for years. It’s always a big hit!
    I only want to point out that when using the 2X or 3X button it changes ingredients by volume (cups) however not by weight. Glad I was paying attention as I always weigh my ingredients and knew that 2c flour is 240g not 120 as stated. GREAT RECIPE

    I like this recipe because we cook the zucchini first. I also added cinnamon and nutmeg and little flour. People did not believe not apple crisp.
