Preheat the oven to 375 degrees F (190 degrees C). Grease a 9x13-inch baking dish.

Bake in the preheated oven for 12 minutes. Remove from the oven; leave oven on.
Mix strawberries, rhubarb, sugar, and flour for filling together in a large bowl; pour into the crust.
Combine flour, brown sugar, and oats for topping in another bowl. Add butter and cut in with a pastry blender until crumbly. Sprinkle over the filling.
Return to the oven and bake until crisp and lightly browned, 40 to 45 minutes.
