Ingredients:

  • 6-7 medium Granny Smith apples, sliced 1/4 inch thick (approx. 3 lbs)
  • 1/2 cup granulated sugar
  • 1 tbsp ground cinnamon
  • 1 tbsp lemon juice
  • 1/4 tsp salt
  • 1 cup old-fashioned rolled oats
  • 1 cup all-purpose flour
  • 1 cup packed light brown sugar
  • 1/2 cup unsalted butter, chilled and cubed
  • 1/2 tsp ground cinnamon
  • 1/4 tsp salt

Instructions:

  1. Preheat your oven to 375°F (190°C). Note: Make sure the oven is fully preheated so the butter in the topping doesn't melt before it sets.
  2. Slice your 6-7 Granny Smith apples into 1/4 inch thick wedges.
  3. In your large bowl, toss the apple slices with 1/2 cup granulated sugar, 1 tbsp cinnamon, 1 tbsp lemon juice, and 1/4 tsp salt.
  4. Transfer the apple mixture into the 9x13-inch baking dish and spread them out evenly. Ensure they aren't all clumped in the center.
  5. In a separate mixing bowl, stir together 1 cup oats, 1 cup flour, 1 cup brown sugar, 1/2 tsp cinnamon, and 1/4 tsp salt.
  6. Add the 1/2 cup chilled, cubed butter to the dry mixture.
  7. Use a pastry cutter or forks to work the butter in until the mixture looks like coarse, pea sized crumbs. Note: Don't overwork it into a paste or you'll lose the crunch.
  8. Scatter the topping evenly over the apples, patting it down gently with your hand.
  9. Bake for 40-50 minutes until the fruit filling is bubbling around the edges and the top is a deep mahogany gold.
