Step 1

Pre-heat the oven to 350 degrees.

Step 2

Roll the pie crust out and transfer to a 9-inch pie pan (if you have a deep dish pan, that’s preferred). Pre-bake the crust 10-15 minutes.

Step 3

Stir together berries, sugar, cornstarch, and lemon juice. Pour into pre-baked pie crust.

Step 4

Combine butter, brown sugar, flour, oats, and salt with a pastry blender or two forks. Crumble over the pie filling.

Step 5

Bake at 350 degrees for 45-60 minutes, or until the crust and crumble topping are golden.
