Preheat the oven to 350°F (175°C).

In a mixing bowl, combine the drained canned peaches, cornstarch, cinnamon, and lemon juice. Mix well.

Pour the peach mixture into the baking dish.

In another bowl, mix together the rolled oats, flour, brown sugar, melted butter, and salt until crumbly.

Sprinkle the crisp topping evenly over the peach filling in the baking dish.

Bake in the preheated oven for 30 minutes, or until the topping is golden brown and the filling is bubbly.

Remove from the oven and let cool slightly before serving.
