Step-by-Step Preparation Method

Step 1: Preheat the Oven

Preheat your oven to 350°F (175°C). Lightly grease a 9×9-inch baking dish.

Step 2: Prepare the Zucchini

Wash and shred the zucchini. Lightly squeeze out some excess moisture using paper towels, but don’t remove all the liquid because it helps keep the filling tender.

Step 3: Make the Filling

In a large bowl, combine the shredded zucchini, granulated sugar, brown sugar, flour, cinnamon, nutmeg, vanilla, lemon juice, and salt. Stir until everything is evenly coated.

Step 4: Transfer to Baking Dish

Spread the zucchini mixture evenly into the prepared baking dish.

Step 5: Prepare the Crisp Topping

In another bowl, combine rolled oats, flour, brown sugar, cinnamon, and salt.

Step 6: Add the Butter

Cut the cold butter into the dry ingredients using a pastry cutter or your fingertips until the mixture resembles coarse crumbs.

Step 7: Add the Topping

Evenly sprinkle the oat crumble over the zucchini filling.

Step 8: Bake

Bake for 40–45 minutes, or until the topping is golden brown and the filling is bubbling around the edges.

Step 9: Cool Slightly

Remove from the oven and allow the crisp to cool for about 10–15 minutes before serving.

Step 10: Garnish and Serve

Serve warm with vanilla ice cream, whipped cream, or a drizzle of caramel sauce for an extra-special dessert.
