Preheat the oven to 350F.

Chop the asparagus into bite-sized pieces, and place them in a baking dish.

In a jug or bowl, combine the heavy cream, garlic paste, ¼ cup of the grated Parmesan, salt, pepper, and lemon balm.

Stir well, then pour the mixture over the asparagus. Stir to coat the asparagus.

Cover and roast in a preheated oven for 15 minutes.

Uncover, stir again, and sprinkle the remaining ¼ cup Parmesan over the top. Return to the oven (uncovered) for another 10-15 minutes or until the asparagus is cooked to your liking.
