1-First Step: Start with the crust. Combine 1 1/4 cups flour and 1/2 cup cold butter in a bowl. Cut butter into flour using a pastry blender until pea-sized crumbs form. Add 3-4 tbsp ice water, one tablespoon at a time, stirring until dough holds together. Press into a 9-inch pie dish, crimp edges, and chill for 30 minutes. This prevents shrinkage during baking.

2-Second Step: Peel, core, and thinly slice 6-7 cups Granny Smith or Braeburn apples. Toss with 3/4 cup sugar, 2 tbsp flour, 1 tsp cinnamon, 1/4 tsp nutmeg, and 1 tbsp lemon juice. Let sit 10 minutes to release juices, then drain excess liquid. Layer evenly into the chilled crust. The spices create that classic Dutch apple pie flavor profile.

3-Third Step: For the crumb topping, mix 1 cup flour, 1/2 cup brown sugar, 1/2 cup cold cubed butter, 1/2 cup oats, and 1 tsp cinnamon. Use fingers or a fork to blend until crumbly and moist do not overmix. Generously sprinkle over the apples, covering completely. This streusel apple pie topping bakes into a golden crunch.

4-Fourth Step: Preheat oven to 375°F. Place pie on a baking sheet to catch drips. Bake 15 minutes at 375°F for high heat to set the crust. Reduce to 350°F and bake 40-45 more minutes until topping golden and apples bubble. Tent edges with foil if browning too fast. Total bake time: 55-60 minutes.

5-Final Step: Cool on a wire rack 3+ hours before slicing this sets the filling. Serve warm with whipped cream or ice cream. For dietary tweaks, use gluten-free flour throughout or vegan butter. This easy apple pie yields 8 servings, perfect for family or guests. Store leftovers properly to enjoy later.
