Preheat oven to 350°F (175°C). Line a small baking sheet with parchment.

Score Brie with a few shallow cuts for even melting.

Arrange Brie on the sheet. Fan apple slices over and around the cheese.

Drizzle honey and lemon juice over apples and Brie. Sprinkle nuts if using.

Bake 12–15 minutes until Brie is soft but not runny; watch closely.

Transfer to a board. Serve with crackers or bread while warm.
