Preheat oven to 425°F | 220°C.

Arrange asparagus in a single layer on a baking sheet (or tray). Spray with cooking oil spray; season with salt; and roast in preheated HOT oven until vibrant in colour and tender-crisp, (about 10 minutes).

While the asparagus is in the oven, heat a small saucepan / pot over medium heat. Add butter and cook, stirring constantly, until it melts, froths up and begins to turn golden in colour. Take off heat; add the garlic and stir quickly. Return to the heat for a further minute, while stirring, until the butter reaches a dark amber colour. Remove from heat; add lemon juice and stir to combine. Pour into a small serving jug.

To serve, drizzle browned butter over asparagus and sprinkle with parmesan cheese.
