Preheat oven to 350 degrees. Grease/spray a 2-qt baking dish.
Place squash cubes into a buttered 2-quart baking dish; sprinkle with salt and pepper, cardomom, (optional aniseed), and brown sugar. Drizzle the melted butter and lemon juice over the top; toss to coat well.
Bake, uncovered, at 350* oven for about 30-40 minutes or until squash is to desired tenderness.
