Why this recipe works

Perfect marriage of spring flavors.

Inspired by Evan Funke’s Spaghetti al Limone, this pasta has all the best flavors of spring.

With the juice and zest of two whole lemons, this pasta is delightfully lemony, while the addition of basil and parsley lends it an herbaceous note. Capers and olives add a zingy, briny flavor (but feel free to leave out the olives if you prefer), while the crushed walnuts provide a slight nuttiness. And of course, we can’t forget the star of the show – asparagus, the king of spring!

A great way to cook asparagus

In season asparagus doesn’t need much help to taste amazing. Here, asparagus gets lightly pan-fried in olive oil alongside shallots, garlic, and lemon zest. The result is a wonderful crisp-tender texture, which is a nice contrast with the creamy pasta.

Gourmet but easy

This is the kind of dish you might find at a fancy restaurant but it’s simple to make at home! With prep time included, you can get this dish on the table in 45 minutes.

Ingredient notes and substitutions

Lemon Asparagus Pasta ingredients in various small bowls on a wooden cutting board.

Asparagus

One of my favorite spring vegetables, it works wonderfully here alongside the other flavors. If it’s not in season where you are, feel free to swap it out for another green vegetable. Broccoli, brussel sprouts, or even legumes like green beans or snap peas would work well here.

Spaghetti

Spaghetti is the classic pasta option here but any noodle or ribbon shaped pasta would work well here (fettucine, bucatini, linguine, etc.).

Walnuts

Walnuts are a fantastic plant-based source of umami. Here, they get finely ground which helps them cling to the olive oil sauce, much in the same way parmesan cheese does. Alongside the nutritional yeast, walnuts provide a great savory backbone to this dish.

Olives and Capers

I know olives can be divisive, so please feel free to leave them out if you can’t stand them. But Castelvetrano olives–the olives in this recipe–are very mild in flavor so you might want to give them a try.

If you do leave them out, consider adding 1 extra tablespoon of capers for a little more of a briny/salty bite

Extra Virgin Olive Oil

Use a good-quality extra virgin olive oil, as it’s the primary ingredient in the sauce. Good quality doesn’t need to be expensive though (I used the California Olive Ranch extra virgin olive oil (affiliate link) – a great olive oil for everyday use).

White beans

While the dish is still satisfying without them, white beans are an optional ingredient that provides some serious heft and protein. Don’t have white beans? Navy beans would also be a fine choice.

How to make this recipe

Trim the asparagus and discard the tough woody ends. Slice each asparagus spear deeply on the diagonal into pieces (about 1/2 to 1 inch).

Make the Lemon Sauce. Juice the two lemons into a jar. Add the Dijon mustard, extra virgin olive oil, and salt/pepper. Shake vigorously until emulsified. Or, whisk all the ingredients together in a bowl.

Heat a bit of extra virgin olive oil in a 12-inch sauté pan (or Dutch oven). Cook the sliced shallots and garlic cloves until golden. Add the red pepper flakes (if using) for 30 seconds.

Add the sliced asparagus and half of the lemon zest (from one lemon).

Cook for 3 minutes, until asparagus is crisp-tender. Take off the heat and let sit until the pasta is ready.

Cook the pasta in a pot of boiling salted water. While cooking, prepare the rest of the ingredients. Chop the basil and parsley, slice the olives, crush the walnuts, rinse and drain the white beans (if using).

Once the pasta is just al dente, reserve up to 1 cup of the cooking water, then drain (do not rinse!). Transfer the hot cooked pasta and Lemon Sauce to the pan with the asparagus.

Add the crushed walnuts and nutritional yeast.

Pour in 1/2 cup (120 mL) of pasta water and return the pan to medium-high heat. Use tongs to toss the mixture quickly and vigorously, until emulsified and creamy. Add more pasta water as needed.

Add the remaining ingredients – basil, parsley, capers, olives, remaining lemon zest (from one lemon), and white beans (if using).

Toss again to combine and briefly cook. Serve warm.

Tips for making this recipe

Use less water than you’d think

Without any cream or cheese, we need a very starchy pasta water to bind our sauce together.

To achieve this, use a bit less water to cook the pasta than you might typically use. For 10 to 12 ounces (285-340g) of pasta, that translates to about 9 cups (~2.1 liters/quarts) of water. 

And of course generously salt the pasta water – about 2 to 3 teaspoons kosher salt (use less if using table salt or sea salt) to ensure the pasta itself has flavor from within.

Cook the pasta until just al dente

Aim to remove the pasta from the water as soon as it’s al dente, or even a minute beforehand, as the pasta is going to continue to cook in the lemon sauce for a few minutes. Otherwise, the texture might be a bit overdone.

For the creamiest and sauciest texture, enjoy this pasta shortly after making it. That’s not to say the leftovers aren’t tasty. They are. But this dish is the most luscious when eaten on day one.

Choose the right pan

When cooking the shallots, garlic, and asparagus, use a large 12-inch frying pan with relatively deep sides, or a Dutch oven. All of the pasta and mix-ins will be added into this pan at the end, so it helps to have a large enough pan to avoid any spills or mess.

Frequently Asked Questions

What’s the best way to cut asparagus?

Most of us have been taught that to cut asparagus, you bend it until it snaps. And the bottom portion that snaps off is too woody and tough to eat. WRONG!
Instead, use your eyes to see where the asparagus look like they’re starting to get tough, about an inch or two up the ends. Then, you can slice a big batch of them in one fell swoop. This is the technique that the fine people over at Serious Eats also recommend.

Or, if you want to be more precise, you can slice each asparagus spear for this recipe. And once your knife starts to feel some tension, you know that this particular spear has hit its tough end. Watch this video to see how I cut my asparagus for this recipe.

Can I use gluten-free pasta?

You can, with a few caveats.

First, gluten-free pasta tends to get mushy, so you’ll really need to ensure you stop cooking the pasta once it’s just al dente.

And second, gluten-free pasta tends to be more absorbent, so you may want to add more pasta water (up to 1 full cup) when you coat the pasta.

What should I serve this lemon asparagus pasta with?

If you add the white beans to this recipe, this is a complete meal on its own (perhaps only more complete with a crisp glass of white wine).

If you omit the beans, it’s still quite satisfying, but you can serve the pasta along with a salad (a Caesar salad or simple mixed greens work well). Or on the side of blanched or roasted vegetables, such as broccolini/broccoli. For a protein option, a simple white bean salad works great (mix cooked or canned/drained/rinsed white beans with a bit of good-quality extra virgin olive oil, lemon juice, salt, and pepper).

How do you can I store and reheat lemon asparagus pasta?

Store in an airtight container in the fridge for 3 to 4 days. The pasta is best shortly after making, when the sauce is creamy and satiny. 

I actually prefer leftovers cold over warmed up. If you want to reheat, heat the leftovers in a skillet over medium-low heat. Add a splash of water as needed to thin and toss frequently. If needed, perk the pasta up with some fresh lemon zest and/or juice.

In the mood for even more pasta? I’ve rounded up 30 of the best vegan pasta recipes from around the web! There are so many great choices, though I’m partial to the Lentil Bolognese during winter and the Vegan Pasta Salad in summer. Check it out!

Prep Time: 25 mins

Total Time: 45 mins
Course: Dinner, Lunch
Cuisine: Italian-Inspired
Diet Vegan
Serving size: 4 to 6

Ingredients

  • 10 to 12 ounces of spaghetti, bucatini, linguine, or fettuccine
  • 2 medium-large lemons*
  • Extra virgin olive oil
  • Kosher salt
  • Freshly cracked black pepper
  • 1 teaspoon Dijon mustard
  • 2 medium shallots, thinly sliced
  • 4 garlic cloves, thinly sliced
  • ¼ teaspoon red pepper flakes (optional)
  • 1 bunch of asparagus (about 14 ounces), sliced thinly on the diagonal into 1-inch pieces**
  • ½ cup (60g) toasted or roasted walnuts***, finely crushed
  • 3 tablespoons nutritional yeast
  • ½ cup (6-7g) Italian flat-leaf parsley, (leaves and tender stems), chopped
  • ½ cup (7-8g) fresh basil leaves, slivered
  • 2 tablespoons capers, drained
  • ¼ cup (30g) Castelvetrano olives, sliced in half (7 to 9 olives)****
  • 1 can of navy beans or other white beans rinsed and drained (optional)

Instructions

  • Bring a large pot of water to a boil for the pasta.
    Tip: Don’t use too much water, otherwise the pasta water won’t be very starchy. I recommend about 9 cups (~2.1 L) of water for 10 to 12 ounces of pasta. Once the water is nearly boiling, add a generous amount of salt (2 to 3 teaspoons of kosher salt).
    Add the pasta and once it returns to a boil, cook according to the package directions, stirring occasionally, until just al dente. Drain the pasta, reserving 1 cup of the pasta cooking liquid.
  • Zest the lemons and divide the zest into two piles (you'll get about 1 tablespoon zest per lemon). Set aside.
  • Meanwhile, make the Lemon Sauce. Add the juice from both lemons (about 6 tablespoons) to a mason jar. Add ¼ cup (56g) extra virgin olive oil, Dijon mustard, and season with 1 teaspoon kosher salt and black pepper to taste. Shake until emulsified.
    No jar? Just whisk all the ingredients in a bowl until emulsified.
  • Cook the asparagus. Meanwhile, heat 1 ½ tablespoons extra virgin olive oil in a 12-inch sauté pan or Dutch oven over medium heat. Once warmed, add the shallots and garlic. Cook for 2-3 minutes, until the garlic is just golden, stirring frequently to prevent burning. Add the red pepper flakes (if using) and cook for 30 seconds.
    Add the asparagus pieces and one half of the lemon zest. Season with a few pinches of salt and pepper. Cook for 3 minutes until the asparagus is crisp-tender. Remove from heat and set the pan aside until the pasta is done.
  • Add the hot cooked pasta and the Lemon Sauce to the asparagus mixture, along with the crushed walnuts and nutritional yeast. Add ½ cup (120 mL) of the reserved pasta water. Return the pan to medium-high heat. Use tongs to vigorously toss everything together, shaking the pan as you go, adding more pasta water as needed, until the sauce is emulsified and clings to the pasta.
  • Add the remaining half of the lemon zest, basil, parsley, capers, olives, and white beans (if using). Toss again and briefly cook for 1 minute. Sprinkle with a final pinch or two of salt and black pepper before serving. Serve warm.

Notes

This recipe is inspired by Spaghetti al Limone with Asparagus from Bon Appétit
* The lemons should feel heavy for their weight. If you can’t find lemons that are medium-large, buy an extra third lemon to ensure you get enough zest and juice. 
** To see how to trim and slice asparagus, watch the video in the “how to cut asparagus” section. 
*** To toast raw walnuts, just add to a dry skillet over medium heat and cook, stirring occasionally, until a bit browned and fragrant, 4 to 5 minutes. You can also use raw walnuts, but you’ll get more flavor from toasted. 
*** If your olives are already pitted, slice them in half. If they have the pits inside, here’s how to remove the pits

    Delicious!! Didn’t have any green asparagus, so I swapped them for broccolini. The flavour of lemon and capers is amazing.

    1. Kaitlin @ Rainbow Plant Life

      We’re delighted you enjoyed the pasta, Jarro! Broccolini sounds like a great swap!
