Ingredients You’ll Need

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

To make this fresh and zesty Lemon Pesto Pasta, you’ll need:

½ lb dried spaghetti (or linguine)
1 lemon (zest + juice)
½ oz finely grated Parmesan cheese (about ¼ cup, plus extra for serving)
¼ cup raw cashews
2 tablespoons extra-virgin olive oil
¼ teaspoon fine sea salt
⅛ teaspoon freshly ground black pepper
1 tablespoon butter (salted or unsalted)
1–2 tablespoons chopped fresh basil (optional, for garnish)

These simple ingredients create a creamy, fragrant sauce packed with citrusy brightness and nutty depth.

Let’s Get Started

1. Cook the pasta

Bring a large pot of salted water to a boil. Add the spaghetti and cook until al dente according to package instructions. Reserve 1 cup of pasta water, then drain.

2. Prepare the lemon pesto mixture

While the pasta cooks, finely grate the Parmesan cheese. In a small bowl, combine:

Lemon zest
Lemon juice
Olive oil
Sea salt
Black pepper

Stir in the grated Parmesan until it forms a loose paste-like sauce.

3. Toast the cashews

In a dry skillet, add raw cashews and toast over medium heat for 3–4 minutes until fragrant and lightly golden. Roughly chop or leave them whole for extra crunch.

4. Combine everything

In the warm pot, melt the butter. Add the cooked spaghetti and toss gently. Pour the lemon-Parmesan mixture over the pasta and stir until everything is coated.

Add splashes of reserved pasta water as needed to create a silky sauce.

5. Add basil and cashews

Sprinkle in the toasted cashews and chopped basil (if using). Toss again to combine.

6. Serve and garnish

Plate the pasta and finish with extra Parmesan, basil, and a squeeze of fresh lemon if you want more brightness.

Servings and Pairing

This recipe yields 2–3 servings, perfect for a light dinner or side dish.

It pairs beautifully with:

Grilled chicken or shrimp
Roasted vegetables (asparagus, tomatoes, broccoli)
Garlic bread
Mixed green salad with lemon vinaigrette
White wines like Pinot Grigio or Sauvignon Blanc

Variations

Creamy Lemon Pesto Pasta

Add 2 tablespoons heavy cream or a spoonful of Greek yogurt.

Vegan Version

Use vegan Parmesan and plant-based butter.

Protein Boost

Add grilled salmon, chicken, tofu, or white beans.

Extra Veggie Version

Mix in spinach, peas, cherry tomatoes, or zucchini ribbons.

Nut Substitutes

Swap cashews for pine nuts, pistachios, or almonds.

Storage Tips

Refrigerate: Store leftovers in an airtight container for up to 3 days.
Reheat: Warm gently in a skillet with a splash of water or olive oil.
Freezing: Not recommended, as lemon sauces lose texture when thawed.

FAQs

Can I use bottled lemon juice?

Fresh lemon is strongly recommended — the flavor is much brighter and cleaner.

Do I have to use cashews?

No. They add texture and creaminess, but you can use any nut or leave them out.

What pasta shapes work best?

Spaghetti, linguine, fettuccine, or short shapes like penne all work well.

Can I add store-bought pesto?

Yes! Stir 1–2 tablespoons into the sauce for stronger basil flavor.

Why is my sauce too thick?

Add more reserved pasta water to loosen it into a glossy, silky finish.
