Ingredients

Instructions

  1. Step 1: Preheat oven to 375°F. In a mixing bowl, toss 4 medium sliced peaches with 1/4 cup granulated sugar, 1 tbsp lemon juice, and 1 tsp ground cinnamon until the peaches are evenly coated.
  2. Step 2: Transfer the peach mixture to a 9-inch baking dish, spreading it out evenly.
  3. Step 3: In a separate bowl, combine 3/4 cup rolled oats, 1/2 cup all-purpose flour, 1/3 cup packed brown sugar, 1/4 tsp ground nutmeg, and 1/8 tsp salt. Add 5 tbsp cold diced unsalted butter and use your fingers or a pastry cutter to blend until the mixture resembles coarse crumbs.
  4. Step 4: Sprinkle the oat mixture evenly over the peaches. Bake uncovered for 35-40 minutes until the topping is golden brown and the peach filling is bubbling around the edges. Let cool for 10 minutes before serving.
