Ingredients

For the Zucchini Filling:

  • 8 cups zucchini peeled, seeded, and diced zucchini (cut about the size of canned pineapple tidbits)
  • 1/3 cup lemon juice
  • 1/3 cup lime juice
  • 1 cup granulated sugar
  • 1 tsp ground cinnamon
  • 1/2 tsp ground nutmeg

For the Crust & Crumble Topping:

  • 2 cups all-purpose flour
  • 2 cups Old fashioned oats
  • 2 cups granulated sugar
  • cups cold butter cubed
  • 1 tsp salt for sprinkling on top

Instructions

Prepare the Zucchini Filling

  • In a large saucepan, combine zucchini, lime, and lemon juice. Cook over medium-low heat for 15–20 minutes, or until the zucchini is tender and translucent.
  • Stir in sugar, cinnamon, and nutmeg. Cook for 1 more minute, then remove from heat and let sit.

Make the Crust & Topping

  • In a large mixing bowl, combine flour and sugar.
  • Cut in the cold butter using a pastry cutter or two forks until the mixture resembles coarse crumbs (like pea-sized pieces).
  • Stir in oats and salt
  • Take ½ cup of the crumb mixture and stir it into the zucchini mixture to help thicken it. Let it sit for a couple minutes.

Assemble the Crisp

  • Grease a 15x10-inch jelly roll pan (or a rimmed baking sheet).
  • Press half of the remaining crumb mixture firmly into the bottom of the pan to form the crust.
  • Spread the zucchini mixture evenly over the crust.
  • Crumble the rest of the topping over the zucchini.

Bake

  • Bake at 375°F for 35–40 minutes, or until golden brown and bubbly.
  • Let cool for 5 minutes, then serve with ice cream or whipped cream.
