Start by washing and peeling the peaches. Slice them into wedges and place them in a large mixing bowl.

Add sugar, lemon juice, and cinnamon to the bowl of peach slices and gently toss until coated.

Transfer the coated peaches into a greased baking dish, distributing them evenly.

In a separate bowl, combine oats, brown sugar, salt, and flour. Add softened butter and mix until crumbly.

Sprinkle the oat mixture over the prepared peach filling.

Preheat your oven to 375°F and then bake for about 40 minutes.

Remove from the oven, let cool slightly, and serve warm with vanilla ice cream.
