Happy Spring! This is the time of year I like to swap out the cauliflower, broccoli, and Brussels sprouts for tender spring asparagus!  This Roasted Asparagus recipe couldn’t be any easier- it’s fast, flavorful, and pairs well with pretty much everything.

At our restaurant and in our catering business, asparagus was hands-down the most popular vegetable side dish. And there’s no question why, it seems to brighten up any plate and give it life and vitality. Plus it’s just delicious. 😉

The three most popular ways we cooked asparagus were roasted, like you see here, sauteed (or stir-fried), or grilled. All are amazing! The secret to perfect asparagus, no matter which way you decide to prepare it, is not to overcook it—you want it tender-crisp.

Roasted Asparagus ingredients

  • Fresh asparagus spears – see chef’s tips below!
  • Extra virgin Olive oil
  • Garlic cloves, or garlic paste.
  • Fresh lemon juice (and lemon zest)
  • Seasonings: sea salt,  fresh black pepper, and optional red pepper flakes.
  • Optional additions: toasted almonds,  pinenutsAleppo chili flakes, grated parmesan or pecorino

Roasted asparagus (Instructions)

Step 1: Trim the ends. Break off the end of one spear of asparagus and note where it naturally breaks. Use this as a guide to where to trim the rest of the bunch of asparagus.

Gather the bunch, then trim off all the woody ends of all the asparagus using a sharp knife.

Step 2: Toss with marinade. Place the asparagus in a bowl and toss with olive oil, garlic, and lemon zest, sprinkle with salt and pepper.  See the chef’s tips for marinating ahead.

Step 3:  Place asparagus on a parchment-lined sheet pan or baking sheet in a single layer.

Step 4: Bake! Bake in a preheated 400 F oven until tender-crisp.  Depending on the thickness of the spears, asparagus can roast anywhere from 15 to 25 minutes. Turn halfway through.  Tiny asparagus can be done quite quickly, whereas pencil-thin takes around 20 minutes, and very thick spears can take 25 minutes.

Chef’s Tips

  • Prep it ahead! When catering large events, I would prep the asparagus ahead. Store marinated asparagus in the fridge for up to 3-4 days, or until ready to bake. It will marinate and become more flavorful over time! Then spread it out on a sheet pan and roast it when you are ready. How easy is that?
  • Add the lemon juice after it bakes– this prevents soggy asparagus.
  • Make sure it is fresh! Always check asparagus tips for firmness, before buying. If they are slimy or mushy, they are past their prime.
  • Bake in a  400F oven! This is the optimal oven temp for tender-crisp asparagus.


Leftovers are delicious!  Store asparagus in an airtight container up to 4 days in the refrigerator and use in scrambles, stir-fries, pasta, etc.

How to use Leftover Roasted asparagus

Asparagus can be served in many ways- for breakfast with toast and poached eggs, (or in a frittata)  for lunch, tossed with pasta or added to a Buddha bowl, or for dinner alongside any protein like Baked chicken, Baked Salmon, Grilled Flank Steak or Tofu.

Roasted Asparagus with olive oil, garlic, lemon zest, baked at 400F, in about 20 minutes. A fast, easy, healthy vegetable side dish that pairs with so many things!


  • 1216 ounces fresh asparagus (pencil-thin)
  • 12 tablespoons olive oil
  • 2 garlic cloves, finely minced – use a garlic press
  • Salt and pepper to taste
  • 1 tablespoon lemon zest
  • a squeeze of lemon juice (after it’s roasted)

Optional Garnishes:  finely grated parmesan or try vegan cheesy sprinkle, toasted slivered almonds or toasted pinenuts, basil or flat-leaf parsley, chili flakes 


  1. Preheat oven to 400F
  2. Trim asparagus: Hold one spear of asparagus in your hand, and with your fingers snap off the rough end. Note where it naturally breaks. Use this as a guide to trim the remaining asparagus, laying it next to the others. Cut the remaining spears to match this length.
  3.  Toss the trimmed asparagus in a bowl with olive oil, garlic, lemon zest, salt & pepper.
  4. Lay spears out in a single layer on a  parchment-lined sheet pan.
  5. Roast until just tender-crisp (yet still vibrant green), about 15-25 minutes, depending on size and thickness, tossing halfway through. 
  6. Once tender squeeze with lemon juice, and give a good toss. Taste for salt, adding more if needed. 
  7. Place in a serving dish and garnish with any of the optional garnishes. 


Both marinated raw asparagus and roasted asparagus will keep in the fridge for up to 4 days.

For more flavor, add sliced shallot to the mixture.
