The roasting time for asparagus generally ranges from about 8 to 20 minutes, depending on the thickness of the spears and the oven temperature.
- For thin asparagus spears, roasting typically takes about 9 to 12 minutes at 425°F, yielding crisp-tender results
- Thicker asparagus stalks require longer roasting, around 15 to 20 minutes at 425°F, to become tender and develop a roasted flavor
- Many recipes recommend roasting at 425°F for about 10 to 15 minutes, checking at 10 minutes for crisp-tender asparagus and up to 15 minutes for more tenderness
- Some suggest roasting at slightly lower temperatures like 400°F for about 10 to 12 minutes to achieve a tender-crisp texture without overcooking
- It's best to arrange asparagus in a single layer without crowding the pan to avoid steaming and ensure proper browning
In summary, roasting asparagus at 425°F for 10 to 15 minutes is a reliable guideline, adjusting time based on spear thickness and desired tenderness. Thin spears roast faster (around 9-12 minutes), while thicker ones may need up to 20 minutes
