Ingredients for Lemon Asparagus Pasta

10 ounces (285g) of spaghetti, bucatini, linguine, or fettuccine
2 medium-large lemons
6 1/2 tablespoons extra virgin olive oil, divided
Kosher salt and freshly cracked black pepper
1/2 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 a bias into 1-inch (2.5 cm) pieces
½ cup (60g) toasted walnuts, finely crushed
3 tablespoons nutritional yeast
½ cup (8g) Italian flat-leaf parsley, chopped
½ cup (8g) fresh basil leaves, slivered
2 tablespoons capers, drained (optional)
¼ cup (30g) Castelvetrano olives, halved (optional)
1 (15-ounce/425g) can navy beans or other white beans, rinsed and drained (optional)

How to Make Lemon Asparagus Pasta

Bring a large pot of salted water to a boil. Cook the pasta until just al dente, stirring occasionally. Reserve 1 cup (240 mL) of pasta water, then drain.
While the pasta is cooking, zest both lemons, dividing the zest into two equal portions. Juice the lemons and combine 5 tablespoons (75 mL) of the juice with 5 tablespoons olive oil, Dijon mustard, salt, and pepper in a jar. Shake or whisk until emulsified.
In a large 12-inch sauté pan, heat 1 ½ tablespoons olive oil over medium heat. Add the shallots and garlic, cooking for 2-3 minutes until the garlic begins to turn golden.
Stir in the red pepper flakes (if using) and cook for another 30 seconds. Add the asparagus and half of the lemon zest, seasoning with salt and pepper. Cook for 3 minutes until tender-crisp.
Reduce heat to low and add the drained pasta, prepared Lemon Sauce, crushed walnuts, nutritional yeast, and ½ cup of pasta water. Toss vigorously to coat the pasta, adding more pasta water if needed for a glossy sauce.
Stir in parsley, basil, the remaining lemon zest, and optional add-ins like capers, olives, or navy beans. Briefly warm everything together for 30-60 seconds.
Serve immediately with a drizzle of olive oil and freshly cracked pepper.

How to Customize This Lemon Asparagus Pasta for Your Diet

Lower calorie: Use zucchini noodles or spaghetti squash to reduce carbs and calories.
Higher protein: Add grilled tofu or chickpeas for an extra protein boost.
Keto-friendly: Swap the traditional pasta for shirataki noodles or spiralized vegetables.
Nut-free: Replace walnuts with toasted sunflower seeds or omit entirely.

Our Team’s Tips for the Best Lemon Asparagus Pasta

Reserve starchy pasta water: This is crucial for creating a silky, emulsified sauce. Use less water than usual when boiling pasta to concentrate the starches.
Don’t overcook the asparagus: Aim for tender-crisp texture and bright green color.
Serve fresh: This dish tastes best when enjoyed immediately, as the sauce clings to the pasta better when hot.
Use fresh herbs: Parsley and basil add vibrant aroma and flavor that dried herbs can’t replicate.

Lemon Asparagus Pasta FAQs

Can I make this recipe gluten-free?

Yes, simply replace the regular pasta with your favorite gluten-free variety. Chickpea or lentil-based pastas work particularly well for added protein.

What can I use instead of walnuts?

Try toasted sunflower seeds, pumpkin seeds, or omit them entirely if you’re avoiding nuts or seeds.

How do I store leftovers?

Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. Reheat gently with a splash of water or olive oil to loosen the sauce.
