Ingredients

Scale
  • 4 cups mixed berries (strawberries hulled and sliced, blueberries, raspberries), fresh or frozen
  • ⅓ cup granulated sugar
  • 1 tablespoon fresh lemon juice
  • 2 tablespoons cornstarch
  • 1 teaspoon vanilla extract (optional)
  • 1 ½ cups old-fashioned rolled oats
  • ½ cup all-purpose flour (can substitute with almond flour or gluten-free blend for gluten-free option)
  • ⅓ cup packed brown sugar
  • 1 teaspoon cinnamon
  • ¼ teaspoon salt
  • ¾ cup unsalted butter, melted
  • ½ cup chopped pecans or walnuts (optional)

Instructions

  1. Preheat oven to 350°F (175°C).
  2. In a large bowl, combine mixed berries, granulated sugar, lemon juice, cornstarch, and vanilla extract if using. Toss gently to coat evenly.
  3. Transfer the berry mixture to a 9×9-inch baking dish, spreading into an even layer.
  4. In a separate bowl, mix rolled oats, all-purpose flour, brown sugar, cinnamon, and salt until combined.
  5. Pour melted butter over the oat mixture and stir until oats are fully coated and the topping is crumbly but sticks together slightly.
  6. Fold in chopped nuts if using.
  7. Spread the oat topping evenly over the berry layer without pressing down too hard.
  8. Bake for 40 to 45 minutes or until the topping is golden brown and crisp and the berry juices are bubbling around the edges. If topping browns too quickly, cover loosely with foil during the last 10 minutes.
  9. Let the crisp cool on a wire rack for at least 15 minutes before serving to allow the filling to thicken.

Notes

Use old-fashioned rolled oats for best texture. Melt butter gently to avoid burnt flavor. If topping browns too fast, cover with foil during last 10 minutes. For gluten-free, substitute flour with almond or gluten-free blend. For dairy-free, use coconut oil instead of butter and maple syrup instead of brown sugar. Let crisp cool before serving to thicken filling. Leftovers keep up to 3 days refrigerated and can be frozen unbaked for up to 3 months.
