You may not realize it, but zucchini is one of those sneaky vegetables that’s kind of a switch-hitter; it can go savory or it can go sweet. Who knew?

Yep, zucchini can totally be disguised to taste like apples!

I’ve discovered that zucchini desserts are kind of few and far between, and they are named things like Zucchini Crumble, Zucchini Apple Pie, or Zucchini Apple Casserole….all are likely very similar to this recipe, but not quite as delicious. 🙂

Ingredients for Zucchini Dessert

Zucchini
Granulated sugar
Cornstarch
Spices: cinnamon, nutmeg
Lemon juice (this is an important ingredient for making the zucchini taste like apples – don’t skip it!)
Old-fashioned (whole) oats
Dark brown sugar
Flour
Vanilla extract
Butter

How to Make Zucchini Crunch

Preheat the oven to 350 degrees F.

Place the zucchini chunks into an 8” x 12” baking dish; toss with the cornstarch and sugar.

In a mixing bowl, combine the melted butter, flour, brown sugar, oats, cinnamon, nutmeg and vanilla until blended.

Spread the oatmeal mixture evenly over the zucchini in the baking dish.

Bake, uncovered, on the center rack of the oven for 30-35 minutes or until golden brown and the zucchini filling is hot bubbly.

Serve topped with ice cream or whipped topping.

Can I make Zucchini Oatmeal Crunch ahead of time?

If you make and bake Zucchini Oatmeal Crunch ahead of time, I’d only do it a few hours ahead, say 5-6 hours or so.

Sometimes it can get a bit soggy after it sits.

OR, even better, you could assemble it, stash it in the fridge, then bake it fresh when you’re preparing to serve dessert.

Can I add berries

Adding berries to the zucchini works really well, even helping to further disguising the zucchini as fruit!

Place the zucchini mixture into your baking dish, then top with the berries and the oatmeal crunch topping.

Double the oatmeal topping

You can totally double the oatmeal topping for this dessert if you so desire.

You may just need to bake it a little longer to be sure the topping gets fully cooked all the way through.
