Ingredients and Helpful Swaps

• 1 lb asparagus
• ½ cup pistachio nuts – (see note 1)
• 2 tablespoons lemon juice
• 1 teaspoon lemon zest – (from 1 lemon)
• 1/2 cup fresh parsley leaves
• 2 extra virgin olive oil
• 1 garlic clove – small, optional
• salt
• pepper
• 12 oz pasta of choice – farfalle, penne, spaghetti, rigatoni, linguine

Step-by-Step Directions

1. Bring a small pot of salted water to a boil.
2. Trim woody ends off the asparagus, chop into small pieces, and rinse.
3. Blanch asparagus in the boiling salted water about 5 minutes until tender and bright green; drain and rinse under cold water and set the asparagus tips aside for garnish.

4. Bring a large pot of salted water to a boil; add the pasta and cook according to package instructions, reserving about 1 cup of the pasta cooking water before draining.

   

5. Pulse the pistachios (or chosen nuts) in a blender or food processor until finely chopped.
6. Add the blanched asparagus, garlic, lemon juice, parsley, olive oil, a pinch of salt and pepper to the blender and puree until smooth; taste and adjust seasoning.
7. Drain the pasta and toss it with the asparagus pesto, adding reserved pasta water as needed to make the sauce silky and coat the pasta.

8. Plate the pasta, top with the reserved asparagus tips, sprinkle with lemon zest, and serve immediately while warm.

   

Tips for Best Results

• Choose the freshest asparagus you can find, preferably in season — it makes all the difference in flavor and color.
• Feel free to swap the pistachios for your favorite nuts — cashews, pine nuts, or almonds all work beautifully.
• You can go chunky or totally smooth with this pesto depending on how long you blend it and your blender’s power. I like mine a little chunky for texture, but if silky smooth is your style, blend longer!

• If you’re a cheese fan, stir in 1/2 cup (about 40 grams) of parmesan or vegan parm for a cheesy boost — or lean into the cheesy vibe with Roasted Parmesan Asparagus as a simple side.

• Don’t forget to save some pasta cooking water! Its starch helps the sauce become glossy and cling perfectly to the noodles.
• This asparagus pesto pasta also tastes fantastic chilled, so pack it up for a picnic or day out for an easy cold pasta salad — or, for another make-ahead option, try a lemony asparagus salad with shaved cheese and nuts.

Ways to Customize

This pesto is super versatile. Slather it on hot cooked pasta or toss it into a refreshing cold pasta salad. You can also stir it into creamy risotto—try our Instant Pot Mushroom Risotto—or even blend it into soup for a flavor boost. Thin it with a splash of water and use it as a bright salad dressing or spread it on bruschetta, toast, or sandwiches for a fresh pop of spring flavor.

Plus, it makes a wonderful dip for crusty bread—like My Mother’s Peasant Bread—oatcakes, or crunchy veggies — perfect for snacking and entertaining.

How to Store and Freeze

Asparagus pesto is a dream for meal prep. Store it in a glass jar or airtight container:

• In the fridge for up to 3 days, so it’s ready for quick dinners.
• Or pop it in the freezer for up to 3 months for easy future meals.

If you happen to have leftovers, this pasta is delicious cold as a pasta salad (and leftover pesto is great whisked into an asparagus frittata). Or gently reheat in the microwave or on the stove with a splash of water to loosen up the sauce and keep it silky.

Frequently Asked Questions

• Can I use other nuts instead of pistachios? Absolutely! Cashews, almonds, or pine nuts all make great alternatives. Just pick unsalted nuts and adjust the amount to suit your taste.
• What about nut allergies? No worries — try toasted sunflower seeds or pumpkin seeds (pepitas) instead for creaminess. You can also boost the olive oil and blanch a little extra asparagus to get a smooth texture.
• Is this recipe vegan? Yes! The recipe as is is completely vegan and dairy-free. If you want, you can add parmesan or a vegan cheese substitute for a cheesier flavor. For a simple vegan side to serve alongside, try asparagus with balsamic glaze.
• How do I make pesto smooth or chunky? Use your blender to control texture — blend longer for smooth pesto or pulse briefly if you like it chunky. Adding a bit of reserved pasta water or extra olive oil will also make it creamier.
• Do I need to cook asparagus before blending? Blanching asparagus softens it, mellows its flavor, and keeps that beautiful green color in your pesto. You can use raw asparagus if you like it firmer and with a grassy note, but blanching is best for a silky, vibrant sauce. If you’d rather cook the spears as a topping or side, here’s how to sauté asparagus.
• How should leftovers be stored? Store your asparagus pesto tightly sealed in the fridge for up to 3 days or freeze for up to 3 months. Pasta leftovers are great cold or can be reheated gently with a splash of water to loosen things up.
• Can this be gluten-free? Yes! Just swap in your favorite gluten-free pasta and cook it according to package directions. Easy!
• How do I reheat pasta without drying it out? Warm the pasta on low heat on the stove or in the microwave with a little reserved pasta water or olive oil added. This keeps it saucy and silky.
