First Step: Preheat oven and prep apples
Preheat your oven to 350-375°F (175-190°C). Peel, core, and slice the apples to your preferred thickness about ¼- to ½-inch works well for even baking. Alternatively, dice the apples into 1-inch pieces for a chunkier texture.

Second Step: Prepare cinnamon sugar mixture
In a large bowl, toss the sliced apples with lemon juice to prevent browning. Add light brown sugar, optional granulated sugar, ground cinnamon, optional nutmeg or allspice, cornstarch or arrowroot starch, apple juice or water (if using), and a pinch of sea salt. Mix well to coat the apples evenly.

Third Step: Assemble in baking dish
Transfer the coated apples into a 9×13-inch baking dish or spread evenly on a lined baking sheet. Dot the mixture with small cubes or slices of unsalted butter (or vegan butter alternative) evenly across the top to help with caramelization and richness.

Fourth Step: Bake covered
Cover the dish loosely with foil and bake for 30 to 45 minutes, depending on the thickness of apple slices and your oven. Every 10-15 minutes, gently stir the apples to blend the sauce and promote even caramelization.

Fifth Step: Finish baking uncovered
Remove the foil and continue baking uncovered for an additional 10 to 15 minutes. This step thickens the sauce further and allows the apples to become tender and caramelized.

Final Step: Rest and serve
Allow the baked apples to rest for about 10 minutes before serving; this helps the sauce thicken and flavors to develop fully. Serve warm alone, or topped with dairy-free or regular vanilla ice cream, whipped cream, or alongside oatmeal or pancakes for a comforting treat. Adapt toppings as needed for dietary preferences.
