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.

Once cooked, transfer the zucchini and liquid to a 9×13 inch (or similarly sized) baking dish.

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.

    Thank you for this! I love crisps but I’m allergic to apples. Definitely gonna try this recipe.

  2. Kari says:

    Some of the photos it looks like you used a green zucchini. Others look like you used a yellow one. Did you use 2 different types of squash or does the squash really change color after cooking and baking?

    1. Sarah says:

      Nope, this is all green zucchini! The color changes to yellow once you cook it with the lemon juice 😀

    Just made this on a whim because we have sooooo many zucchini’s. Don’t tell my kids though because they asked for seconds! Great recipe! Thank You

    1. Sarah Bond says:

      I’m so happy to hear it Amber! Sounds like a tasty problem to have 😀

  4. Melissa says:

    Oh my goodness!! We have tons of zucchini to use up (first time growing it!) so I’ve been searching out different recipes to try. This is by far my favorite so far! DELICIOUS!

    1. Sarah Bond says:

      YAY! So glad you enjoyed it, Melissa! Happy zucchini season!

    I printed this and plan to make soon because I have a lot of zukes coming in the garden. Does the sugar act as a thickener, or could I use stevia as a substitute for the white sugar part?
    Also, why is it that every recipe has this format? I hate that half the page is taken up with stuff like cuisine: American or prep time + cook time and then total time! This always forces the recipe to go onto two pages. I always have to copy and paste and rework the entire thing. Can the print pages be more editable? Anyway, the recipe looks great and I’m looking forward to making it.

    1. Sarah Bond says:

      The sugar is simply for sweetness, so you could us stevia! I’ll look into ways of customizing the print page – thanks for your feedback, Barbara!

  6. Cassandra says:

    Can you freeze this dessert?

    1. Sarah Bond says:

      I haven’t tried freezing this zucchini crisp, but I think the texture would be impacted.

  7. marion says:

    Can this be made the day before and then baked the morning of?
    Also does this need to be refrigerated?

    1. Sarah Bond says:

      Yes you could make it in advance, just keep the crumble topping and the zucchini filling separate until ready to make. And yes to refrigeration! 😀

    OMG This recipe is delicious! I did add a little pumpkin pie spice in the apples just for the heck of it. This dish is definitely going with me for Thanksgiving potluck. Thank you for sharing.

    1. Sarah Bond says:

      So happy to hear it, Londa! Enjoy!

    I have made a similar recipe for years. I have never cooked the zucchini on the stove before hand though. Everyone always loves it when I make it.

    1. Sarah Bond says:

      Cooking the zucchini on the stove helps to get some extra moisture out and infuse it with sweet flavors! 😀
