Instructions

Step 1: Preheat the oven to 375°F (190°C). In a large mixing bowl, toss 5 cups sliced ripe peaches with 1/4 cup granulated sugar, 1 tbsp lemon juice, and 1 tsp ground cinnamon until evenly coated.
Step 2: Transfer the peach mixture to a 9x9 inch baking dish, spreading in an even layer.
Step 3: In another bowl, combine 3/4 cup old-fashioned rolled oats, 1/2 cup all-purpose flour, 1/3 cup packed light brown sugar, 1/4 tsp ground nutmeg, and 1/8 tsp salt.
Step 4: Cut in 6 tbsp cold unsalted butter cubes using a pastry cutter or fingers until the mixture resembles coarse crumbs with some pea-sized pieces.
Step 5: Evenly sprinkle the oat crumble topping over the peaches.
Step 6: Bake uncovered for 35-40 minutes until the topping is golden brown and the peaches are bubbling around the edges.
Step 7: Remove from oven and let cool 10 minutes before serving with vanilla ice cream or whipped cream if desired.
