Ingredients

Instructions

  1. Step 1: Preheat oven to 375°F. Toss 4 cups peeled, sliced honeycrisp apples with 1/2 cup granulated sugar, 2 tbsp all-purpose flour, and 1 tsp ground cinnamon in a 9x13-inch baking dish until evenly coated.
  2. Step 2: In a bowl, combine 1 cup rolled oats, 1/2 cup chopped walnuts, and 1/4 tsp salt. Cut 1/2 cup cold butter into small pieces and mix with oats until crumbly and pea-sized clumps form.
  3. Step 3: Sprinkle oat mixture evenly over apples. Bake for 40-45 minutes until apples are bubbling around the edges and topping is deep golden brown, then let rest for 15 minutes before serving.
