Ingredients

• 5 medium apples, peeled, cored, and sliced
• 1 tablespoon fresh lemon juice
• 1 tablespoon pure maple syrup or honey
• 1 teaspoon vanilla extract
• 1 1/2 teaspoons ground cinnamon
• 1/4 teaspoon ground nutmeg
• 1 tablespoon cornstarch
• 1/2 cup gluten-free rolled oats
• 1/3 cup almond flour
• 1/3 cup chopped pecans
• 2 tablespoons melted butter or coconut oil
• 1 tablespoon pure maple syrup or honey
• 1/2 teaspoon ground cinnamon
• 1/4 teaspoon kosher salt
• Plain or vanilla Greek yogurt for serving, optional

Instructions

1. Preheat the oven to 375°F and lightly grease an 8-inch cast-iron skillet or small baking dish.
2. In a large bowl, combine the sliced apples, lemon juice, maple syrup or honey, vanilla, 1 1/2 teaspoons cinnamon, nutmeg, and cornstarch.
3. Toss until the apples are evenly coated, then transfer them to the prepared skillet or baking dish.
4. In a separate bowl, combine the rolled oats, almond flour, chopped pecans, remaining 1/2 teaspoon cinnamon, and salt.
5. Add the melted butter or coconut oil and remaining tablespoon of maple syrup or honey.
6. Stir until the topping is evenly moistened and small crumbles begin to form.
7. Sprinkle the oat and pecan mixture evenly over the apples.
8. Bake for 30 to 35 minutes, until the apples are tender and bubbling around the edges and the crumble is golden brown.
9. If the topping begins to brown before the apples are tender, loosely cover the skillet with foil for the remaining cooking time.
10. Remove from the oven and allow the crumble to rest for 10 minutes before serving.
11. Spoon into bowls while warm and top with cold Greek yogurt if desired.
