Preheat your oven to 350 degrees F. This step is crucial because a hot oven is key for achieving that beautiful golden brown topping.
Grease a 9×13 inch baking dish to ensure that your Apple Pear Crisp comes out easily after baking. I like to use butter for greasing, as it adds a touch of flavor.
Prepare the fruit base by grabbing a large mixing bowl. Combine the sliced apples, sliced pears, and lemon juice together. Toss them gently to coat the fruit evenly. The lemon juice will help keep the fruit from browning while adding a nice tartness.
In a medium bowl, mix the granulated sugar, light brown sugar, flour, and apple pie spice. Stir well to combine. This mixture will add sweetness and flavor to your fruit.
Sprinkle the sugar mixture evenly over the apples and pears, tossing again to coat. Make sure every piece of fruit gets some of that delicious sugar mix!
Pour the apple and pear mixture into your prepared baking dish, spreading it into an even layer. This is the base of your Apple Pear Crisp.
Now, let’s prepare the topping! In a large bowl, combine the old fashioned oats, all-purpose flour, apple pie spice, salt, pecan chips, and light brown sugar. Mix it all together until it’s well combined.
In a separate bowl, mix the melted butter and vanilla extract together, then pour it over the oat mixture. Stir until everything is evenly coated. This will create a crunchy topping.
Crumble the oat mixture evenly over the top of the apple and pear layers. Don’t worry about making it perfect; rustic is exactly what you want here!
Bake in the preheated oven for 40 to 45 minutes or until the crumble topping is golden brown and the fruit is bubbling underneath. You’ll know it’s almost done when your kitchen smells heavenly.
Once baked, remove the Apple Pear Crisp from the oven and allow it to cool slightly. Serve warm, and if you’d like, top it with a scoop of vanilla ice cream, caramel sauce, or a dollop of whipped cream.
