Place the asparagus in a baking pan. Don’t worry about finding a pan large enough to hold the asparagus in one layer – the stalks can overlap a bit. Drizzle the olive oil over them and toss gently to coat the asparagus evenly. Sprinkle on the salt, and toss again.
Roast the asparagus for 8 to 10 minutes for thin stalks, 10 to 14 for thick ones. If they overlap, just give them a little shuffle with a spatula halfway through the cooking time so they all have a chance to brown a bit. Remember that they will continue to cook a bit after you remove them from the oven, so take them out while they’re still a little firmer than you would like.
