This Apple Crisp without Oats bids adieu to the fastidious pie crust but is no less warming, delicious or comforting than an old-fashioned apple pie. Loaded with sweet-tart apples, and a not-too-sweet crumble topping, it's the perfect dessert for autumn and for all your holiday feasts. The best part? You can throw it together in about 20 minutes or less.
Preheat oven to 400ºF. (See notes below for dual temperature tips). Lightly butter a 9-inch, deep pie dish or a 9x9 casserole dish.
In a medium bowl, stir together the flour, brown sugar, cinnamon and salt. Add the cold butter and using your hands, toss the butter pieces until coated. Using your finger tips, start to smash the butter pieces into the dry mixture. It is done when there are no visible large pieces of butter left, and the mixture holds together when you squeeze it. (Alternatively, you can use a pastry cutter to work in the butter.)
Transfer the topping to the fridge or freezer while you prepare the apples. This will make it easier to scatter the topping evenly over apples and it will also brown more evenly.
Using a vegetable peeler, peel all the apples. Stand your peeled apple upright, place your knife close to the core and cut downward to remove large chunks of apples. You should get 4 chunks from each apple. Then, cut each chunk into slices that are a little thicker than 1/4-inch – so about three-eighths of an inch.
Place the apple slices in a large bowl and toss them with the sugar, cinnamon, salt and apple cider vinegar, if using.
Place the apples and any juices that accumulated in the prepared baking dish and spread out evenly across the bottom of the dish. Evenly scatter the crumble mixture over the fruit.
Bake for 15 minutes then lower heat to 350ºF and bake for 30 more minutes, or until topping is golden brown and filling is bubbling through around the edges. Let cool on a rack for 15 to 20 minutes, then serve and enjoy!
