Preheat the oven to 350°F/180°C. Position the oven rack one level below the center. Butter a 12 x 8-inch baking dish or a medium casserole dish of a similar size.
Make the filling: Place the apple wedges in a large mixing bowl and toss with the lemon juice. Add the flour, brown sugar, granulated sugar, cinnamon, nutmeg, and salt. Toss until the apples are evenly coated.
Add the melted butter and vanilla and toss again. The cinnamon-sugar mixture should cling to the apples rather than look thin or watery. Spread the apples evenly in the prepared baking dish.
Make the topping: In a separate bowl, stir together the flour, oats, granulated sugar, brown sugar, salt, and cinnamon.
Pour in the melted butter and mix until no dry patches remain. Leave some of the mixture in larger clumps rather than breaking everything into fine crumbs.
Scatter the topping evenly over the apples, keeping some of those larger clusters intact.
Bake for 40 to 45 minutes, or until the topping is deeply golden and the apple filling is visibly bubbling up around and through the crisp topping. The apples should be tender when pierced but still hold their shape.
Let the crisp rest for 10 to 15 minutes before serving. Serve warm.
Notes
Note on sweetness: This is an old-fashioned, generously sweet apple crisp. If you prefer less-sweet desserts, use Granny Smith apples instead of reducing the sugar—their tartness provides a nice contrast while keeping the texture and proportions of the original recipe intact.
