In a large bowl, toss the sliced apples with the brown sugar, cinnamon, nutmeg, nuts, raisins, vanilla, and melted butter until evenly coated.
Pour the mixture into the prepared baking dish and spread evenly. Pour the apple cider over the top to help create a syrupy sauce as it bakes.
Cover the dish loosely with foil and bake for 30 minutes. Remove the foil, then bake uncovered for another 30 minutes, or until apples are tender and bubbling.
Stir the apples gently before serving to coat the apples in the cooking liquid.

Notes
Apple Choice: Firmer apples like Granny Smith, Honeycrisp, or Fuji hold their shape best during baking.
Sweetness Level: Adjust the amount of sugar based on the natural sweetness of your apples.
Peeling Optional: You can peel the apples for a softer texture or leave the skins on for more fiber and a rustic look.
Even Baking: Slice apples into uniform pieces so they cook evenly.
Liquid Boost: A splash of apple cider, orange juice, or water in the baking dish helps prevent sticking and adds flavor.
Make It Lighter: Swap butter for coconut oil or reduce the sugar for a healthier version.
Serving Size: Recipe makes about 6 servings, depending on portion size.
