This Cranberry and Apple Crumble has tender thin-sliced apples and tart cranberries baked in a buttery crust, topped with a crunchy oat crumble. It’s cozy, sweet, tart, and perfect with a scoop of vanilla ice cream.
Preheat the oven to 375°F (190°C). Roll out and fit the pie crust into a 9-inch pie pan. Trim edges and flute as desired. Chill in the fridge while you make the filling and crumble.
In a large bowl, toss the apples and cranberries with brown sugar, granulated sugar, cornstarch, spices, lemon juice, and vanilla. Let sit for 10 minutes to help the apples soften slightly.
In a medium bowl, mix oats, flour, brown sugar, and cinnamon. Stir in melted butter until crumbly and well combined.
Pour the apple-cranberry filling into the chilled pie crust and spread evenly. Sprinkle the crumble topping evenly over top.
Place the pie on a baking sheet and bake for 55–65 minutes, or until the filling is bubbly and the topping is golden brown. If the crumble browns too quickly, tent loosely with foil for the final 15 minutes.
Let cool on a wire rack for at least 2 hours before slicing. This helps the filling set properly.
Notes
Thin apples make perfect layers: slice your apples thin and evenly to help them bake through and layer beautifully.
For a crisp topping, don’t over-mix the crumble, you want big chunks!
To prevent soggy crust: use a glass or metal pan and don’t skip the cooling time. It keeps the bottom crust crisp.
Use a baking sheet: Always place your pie pan on a rimmed baking sheet. It catches any bubbling fruit juices, prevents messes, and makes transferring the pie in and out of the oven much easier.
Cool completely before slicing: Let the pie cool for at least 2 hours so the filling can thicken and hold its shape when cut.
