This old-fashioned apple crisp is just like the one mom used to make — tried and tested for the perfect balance of sweet and tart with a crunchy, oat-y, buttery topping.
In the bowl of a stand mixer fitted with the paddle attachment, on low speed, mix flour, brown sugar, white sugar, and salt. Add in oats and continue mixing until well combined.
¾ cup all-purpose flour
1 cup oats
⅓ cup granulated sugar
⅓ cup light brown sugar, packed
¼ tsp kosher salt
Dice chilled butter into ¼" pieces and add into the mixture. Mix on low/medium speed until the mixture comes together and no dry spots remain (about 3 to 5 minutes). Note: The mixture may appear dry at first — that’s OK... just keep mixing!
8 Tbsp (1 stick) unsalted butter, chilled and cut into ¼" cubes
Using your fingers, clump the dry mixture together. Chill in the refrigerator while preparing the apple filling.
Preparing the Apple Filling
In a large bowl, pour in lemon juice.
2 Tbsp lemon juice
Peel, core, and cut apples into ¼" slices. Place apple slices in bowl with lemon juice, stirring occasionally, to prevent them from browning while completing this step.
2 ½ lbs apples
Pour in melted butter and stir.
2 Tbsp unsalted butter, melted
Add in sugar, flour, cinnamon, and nutmeg. Stir until apples are evenly coated.
