Filling ingredients:
3 pounds of a variety of good cooking apples such as Granny Smith, Pippin, Fuji, Golden Delicious, Gravenstein
2 tablespoons lemon juice
4 tablespoons unsalted butter
1/2 cup sugar
1 tablespoon flour
1/2 teaspoon cinnamon
1/4 teaspoon ground nutmeg
1 teaspoon vanilla extract
Crumble:
- 1 1/2 cups brown sugar
- 3/4 + 3/8 cup old fashioned oats
- 3/4 + 3/8 cup all-purpose flour
- 3/4 cup cold unsalted butter, diced into small cubes
- 1 1/2 tsp cinnamon
- pinch of kosher salt
Peel, quarter, and core the apples. Cut them into 1/4 to 1/2 inch chunks. As you prep the apples, add them to a bowl and toss with lemon juice to keep them from oxidizing (turning brown).
2. Make the filling:
Melt the butter in a large pan over medium heat. Add the chopped apples (and the lemon juice from the bowl), sugar, cinnamon, and nutmeg. Toss to coat with everything so that the spices and sugar are well distributed throughout the apples.
Partially cover the pot and cook until the apples are just tender, about 10 minutes.
Stir in the vanilla, and toss to coat with a tablespoon of flour.
Place filling in 9x13 baking dish.
3. Make Crumble Topping:
In a separate mixing bowl, add topping ingredients (brown sugar, oats, flour, cinnamon, salt, and diced cold butter). Use a pastry cutter to cut the butter into the oat mixture, using a slight downward twisting motion, until mixture resembled pea-sized crumbs. Alternatively, you can use two forks or even your hands to cut butter into the mixture.
4. Sprinkle topping on top of filling. Bake at 350° for 35 min until golden brown and bubbly.
