how long to cook asparagus on grill in foil
Fussing With Foil. Wrapping asparagus in foil allows you to cook it on the grill without the thin spears falling through the bars and into the flames and makes cleanup easier. It takes roughly 20 minutes to grill foil-wrapped asparagus. When oven baking, wrapping or covering this vegetable in foil helps it retain some crunch and stops it from drying out, especially if you're cooking finer spears. Bake your asparagus in foil for between 12 and 20 minutes, depending on the thickness of the spears, until they're tender but still crisp.
