Equipment

  • 8x8 or 9x9 Baking Dish
  • Skillet for browning butter
  • Large Mixing Bowls
  • Sharp Knife and Cutting Board
  • Measuring Cups and Spoons
  • Fork (or your hands) for mixing topping

Ingredients
  

Fruit Filling

  • 4 cups peaches, sliced (about 4-5 medium)
  • 2 cups fresh blueberries (or frozen, not thawed)
  • 1/4 cup granulated sugar
  • 1 tbsp cornstarch
  • 1 tbsp lemon juice (from about half a lemon)

Topping

  • 6 tbsp unsalted butter
  • 1 cup old-fashioned rolled oats
  • 1/2 cup all-purpose flour (heaping is fine)
  • 1/2 cup packed brown sugar
  • 1/2 tsp cinnamon
  • 1/4 tsp nutmeg (freshly grated if possible)
  • Pinch of salt

Instructions
 

  • Preheat your oven to 375°F. Butter an 8x8 or 9x9 baking dish (or a 9-inch pie dish).
  • Brown the butter: In a light-colored skillet over medium heat, melt the butter. Swirl occasionally as it foams and sputters. After 3-4 minutes, when the foam settles and you see amber specks at the bottom, and it smells like toasted hazelnuts, pour it into a bowl to cool slightly (about 5 minutes).
  • Prep the fruit: Slice the peaches into 1/2-inch wedges (no need to peel). In a large bowl, toss the peaches, blueberries, granulated sugar, cornstarch, and lemon juice until the juices look glossy.
  • Make the topping: In a separate bowl, whisk the oats, flour, brown sugar, cinnamon, nutmeg, and salt. Pour in the cooled brown butter and stir with a fork or your hands until clumps form. Squeeze a handful – it should hold together. If too dry, add a tablespoon of melted butter.
  • Assemble: Pour the fruit into the prepared dish and spread evenly. Sprinkle the topping over the fruit in an even layer – don't press it down. Place the dish on a baking sheet to catch drips.
  • Bake: Bake for 35-40 minutes, until the fruit is bubbling at the edges and the topping is deep golden brown. The juices should be thick and syrupy.
  • Rest: Let the crisp rest for at least 15 minutes before serving. This allows the filling to set. Serve warm, with vanilla ice cream if desired.

Notes

Don't peel the peaches – the skins soften during baking and add a rosy color. For make-ahead: assemble unbaked, cover, and refrigerate up to 2 days; bake straight from fridge, adding 5-10 minutes. Baked crisp freezes well for up to 3 months – thaw in fridge and reheat at 350°F to re-crisp the topping. If using frozen fruit, do not thaw; add 5 minutes to bake time.
