Do I need to blanch asparagus before roasting?
Nope. Roasting is a direct-to-pan situation. Blanching is useful when you want very bright green asparagus and a softer bite, but for crisp edges and browned flavor, skip it.
How do I keep roasted asparagus from getting soggy?
Three moves: hot oven, single layer, and do not overcrowd. If the pan is packed, the asparagus steams. Use a bigger sheet pan or two pans if needed.
What temperature is best for oven roasted asparagus?
I like 425°F. It is hot enough to brown quickly and keep the centers crisp-tender.
How long do I roast asparagus?
It depends on thickness. As a guide at 425°F: thin spears 8 to 10 minutes, medium 10 to 12, thick 12 to 15. Start checking early because it goes from perfect to overdone pretty fast.
How do I know when asparagus is done?
Look for browned tips and stalks that are tender-crisp. A fork should slide in with just a little resistance. If it flops like a noodle, it is over.
Should I peel asparagus?
Usually no. If the stalks are very thick and woody near the bottom, you can peel the lower third with a vegetable peeler for a more tender bite.
Why is my asparagus bitter?
Some bunches are naturally more bitter, especially older or thicker stalks (and yes, overcooking does not help). A squeeze of lemon, a bit more salt, and a small hit of fat (olive oil, butter, or Parmesan) usually balances it out.
