8large applesabout 3 1/2 pounds McIntosh, Greening Macoun apples, peeled, cored, and sliced about ¾-inch thick
grated zest of 1 lemon
2tablespoonsfreshly squeezed lemon juice
¼cupgranulated sugar
1teaspoonground cinnamon
For the Topping
1cupflour
½cupgranulated sugar
½cuplight brown sugarpacked
¼teaspoonkosher salt
1cupoatmeal
½cup(1 stick) cold unsalted butterdiced
Instructions
Preheat the oven to 400°F. Butter or spray an 8 or 9-inch baking dish.
In the dish itself, toss the apples with the lemon zest and juice, sugar, and cinnamon.
Make the topping: combine the flour, granulated sugar, brown sugar, salt, and oatmeal in medium-sized bowl. Add the diced butter and using your fingers (or a pastry cutter if you have one) blend the butter with the dry ingredients until the butter is in very small bits, like peas or smaller. Distribute the mixture evenly over the apples.
Bake the crisp on a baking sheet with sides for 40 to 50 minutes until the top is brown and the juice bubbles up around the edges. Let sit for at least 10 minutes and serve warm.
Notes
You can also do this by blending the dry ingredients in a food processor, and then pulsing in the butter in until the mixture is mixed as described. Hold the oatmeal back til the end if you use a food processor, and blend that in by hand, so the oats don’t get chopped up.
