The baking time for asparagus depends mainly on the thickness of the stalks and the oven temperature, but generally ranges from about 8 to 20 minutes.

• For thin asparagus stalks (around 1/4 inch thick or less), roast at 400-425°F for about 8-11 minutes.
• For medium thickness stalks (around 3/8 to 1/2 inch thick), roast at 400-425°F for about 12-15 minutes.
• For thick stalks (5/8 inch or thicker), roast at 400°F for 16-20 minutes

Common recommendations include:

• Preheat the oven to 400-425°F (200-220°C).
• Trim off the woody ends.
• Arrange asparagus in a single layer on a baking sheet.
• Drizzle with olive oil and season with salt and pepper.
• Roast until tender but still crisp, with some browning on the tips, usually around 10-15 minutes for most average-sized asparagus

If you prefer a lower temperature, such as 350°F, baking may take longer (around 25 minutes), but higher heat is preferred for better browning and texture

. In summary, the typical baking time to roast asparagus is about 12 minutes at 400-425°F, adjusting slightly based on stalk thickness and desired tenderness.
