Preheat oven to 375°F (190°C). Line a baking sheet with parchment.

Toss apple slices with lemon juice. Mix melted butter, brown sugar, cinnamon, and salt in a bowl.

Pour butter mixture over apples and toss to coat. Spread in a single layer on the sheet.

Sprinkle pecans or raisins if using. Bake 18–22 minutes until tender and slightly caramelized.

Serve warm straight from the pan. Kids will want seconds; I won’t judge.
