Ingredients

Scale
  • 6 large fresh peaches, peeled and sliced
  • 6 tablespoons unsalted butter, browned
  • 1 1/2 cups old-fashioned rolled oats
  • 3/4 cup all-purpose flour (or almond flour for gluten-free)
  • 2/3 cup packed light brown sugar
  • 1/4 cup granulated sugar
  • 1 teaspoon cinnamon
  • 1 teaspoon vanilla extract
  • 1 tablespoon lemon juice
  • 1/4 teaspoon salt
  • Pinch of flaky sea salt for sprinkling
  • Optional: 1/4 cup chopped toasted pecans or walnuts

Instructions

  1. Preheat the oven to 350°F (175°C). Lightly grease an 8×8-inch oven-safe baking dish with butter or nonstick spray.
  2. Peel and slice the peaches into 1/2-inch thick slices. Toss them in a bowl with lemon juice, granulated sugar, vanilla extract, and salt. Let sit while preparing the topping.
  3. In a medium saucepan, melt the butter over medium heat. Stir frequently until it foams and turns golden brown with a nutty aroma. Remove from heat immediately.
  4. In a large bowl, combine rolled oats, flour, brown sugar, cinnamon, and a pinch of salt. Pour the warm brown butter over the dry ingredients and stir until crumbly and evenly moistened. Fold in nuts if using.
  5. Spread the peach mixture evenly in the prepared baking dish. Sprinkle the oat topping evenly over the peaches, gently patting it down but keeping it crumbly.
  6. Sprinkle a pinch of flaky sea salt over the topping.
  7. Bake for 40-45 minutes until the topping is golden brown and peach juices bubble at the edges.
  8. Let the crisp cool for 10-15 minutes before serving to thicken the juices.

Notes

Use medium heat and stir constantly when browning butter to avoid burning. For juicier peaches, add extra flour or oats to the topping. A quick 5-minute broil can restore crunch if topping softens. Prepare peach mixture a day ahead and refrigerate for convenience.
