For the Apple Filling
6largebaking applesabout 2.5 pounds or 1.1 kg, peeled, cored, and sliced (Granny Smith, Honeycrisp, or Golden Delicious work well)

For the Crisp Topping
1cupold-fashioned rolled oats90g
3/4cupall-purpose flour95g
3/4cuppacked light brown sugar165g
1teaspoonground cinnamon
1/2teaspoonsalt
1/2cupcold unsalted butter113g or 1 stick, cut into small cubes
Instructions
Preheat your oven to 350°F (175°C) and lightly grease a 9x13-inch baking dish with butter or non-stick cooking spray.
Peel, core, and slice the apples into 1/4 to 1/2-inch thick slices, keeping them uniform for even cooking.
In a large bowl, combine sliced apples with flour, granulated sugar, lemon juice, vanilla, cinnamon, nutmeg, and salt. Toss until evenly coated and spread in the prepared baking dish.
In a medium bowl, mix oats, flour, brown sugar, cinnamon, and salt. Add cold butter cubes and use a pastry cutter or fork to work it in until the mixture resembles coarse crumbs with pea-sized butter pieces.
Sprinkle the crumb topping evenly over the apple filling, making sure to distribute it all the way to the edges without packing it down.
Bake for 45 to 50 minutes until the topping is golden brown and apples are bubbling around the edges. If the topping browns too quickly, tent loosely with foil.
Remove from oven and let cool for 10 to 15 minutes before serving. Serve warm with vanilla ice cream or whipped cream.
Notes
Choose a mix of apple varieties for best flavor - combine tart Granny Smith with sweet Honeycrisp or Golden Delicious.
Keep butter cold until ready to use for the crispiest topping. If your kitchen is warm, chill the topping mixture for 15 minutes before adding to apples.
Don't skip the lemon juice - it prevents browning and balances the sweetness perfectly.
The flour in the filling absorbs excess moisture and prevents a soggy bottom.
Topping should be deeply golden brown, not pale, when done. You should see bubbling juices around the edges.
Store covered at room temperature for up to 2 days, or refrigerate for up to 5 days. Reheat at 350°F for 15-20 minutes.
Can be frozen for up to 3 months. Thaw overnight in refrigerator before reheating.
For variety, try adding 1/2 cup chopped pecans or walnuts to the topping, or replace 1 cup of apples with fresh cranberries.
This can be assembled up to 2 hours ahead and refrigerated before baking.
Use old-fashioned rolled oats, not quick oats, for the best texture.
