Step 1

Preheat the oven to 375 degrees F (190 degrees C). Grease a 2 quart casserole dish or 9 inch square baking dish.

Step 2

In a medium bowl, stir together the oats, brown sugar, 1/2 cup flour, 1 teaspoon crystallized ginger, and cinnamon. Stir in the butter until the mixture is crumbly with pea sized lumps. Set aside.

Step 3

In a separate bowl, stir together the white sugar, 2 tablespoons flour and 2 teaspoons of crystallized ginger. Add the sliced pears, and toss to blend. Transfer to the prepared baking dish. Spread with the oat topping.

Step 4

Bake for 30 to 35 minutes in the preheated oven, until pears are soft and topping is golden brown. Cool slightly before serving with vanilla ice cream.
