Ingredients
Method
- Boil the pasta: Bring a large pot of well-salted water to a boil. Cook the pasta according to package directions until al dente. Before draining, reserve 1/2 cup of the starchy pasta water.
- Toast the nuts (optional but recommended): In a dry skillet over medium heat, toast pine nuts or walnuts for 2–3 minutes, stirring often, until fragrant and lightly golden. Remove from heat to cool slightly.
- Make the avocado pesto: In a blender or food processor, add avocado, basil, lemon juice, garlic, Parmesan (or vegan alternative), toasted nuts, salt, and pepper. Pulse to combine. With the motor running, stream in olive oil until the sauce is smooth and creamy. Adjust lemon and salt to taste.
- Adjust consistency: Add a splash of reserved pasta water to loosen the sauce if it’s too thick. It should be silky and spreadable, not runny.
- Combine: Return the drained pasta to the pot (off the heat). Add the avocado pesto and a few tablespoons of pasta water. Toss until the sauce coats every strand. Add more pasta water as needed to reach a glossy finish.
- Finish and serve: Taste and adjust seasoning. Top with extra Parmesan, a squeeze of lemon, cracked pepper, and any add-ins like cherry tomatoes or red pepper flakes. Serve immediately.

Keeping It Fresh
Avocado-based sauces can brown if they sit too long, so a few tricks help keep that vibrant green color. – Use lemon generously: The acidity slows browning and brightens flavor. – Press plastic wrap directly on the surface of any leftover sauce before refrigerating. – Store time: The sauce keeps well for about 1 day. After that, expect some color change. – Leftover pasta: Refrigerate in an airtight container for up to 2 days. To freshen, add a splash of warm water or a drizzle of olive oil and a squeeze of lemon before serving. – Avoid heating the sauce directly: High heat can dull the color and flavor.
Toss with warm pasta instead of cooking it in the pan.
Benefits of This Recipe
– Nutrient-dense: Avocado adds heart-healthy fats and fiber, while basil brings antioxidants and fresh aroma. – Lighter than cream sauces: You get a creamy texture without heavy dairy. – Customizable protein: Add grilled chicken, shrimp, chickpeas, or tofu to make it a complete meal. – Friendly for different diets: Easy to make vegetarian, vegan, or gluten-free by choosing the right pasta and cheese alternatives. – Quick cleanup: One pot for pasta and one blender for the sauce.
Pitfalls to Watch Out For
– Underripe avocado: If it’s too firm, the sauce won’t be creamy and can taste flat. Choose one that yields slightly to gentle pressure. – Skipping the lemon: Without enough acidity, the sauce can taste heavy and turn brown faster. – Overcooking the pasta: The sauce clings best to al dente noodles. – Too much garlic: Raw garlic is potent. Start small and add more to taste. – Dry sauce: Don’t forget the pasta water.
It helps emulsify the sauce and makes it glossy.
Recipe Variations
– Spinach-Boosted: Blend a handful of baby spinach with the basil for extra greens and a deeper green color. – Spicy Kick: Add 1/2 teaspoon red pepper flakes or a small jalapeño to the blender for heat. – Lemony Herby: Mix in fresh parsley or mint and an extra tablespoon of lemon juice for a brighter profile. – Nut-Free: Skip nuts and use pumpkin seeds or sunflower seeds, or simply add more Parmesan for body. – Roasted Veggie Bowl: Toss in roasted cherry tomatoes, zucchini, or asparagus for texture and sweetness. – Protein Power: Add grilled shrimp, shredded rotisserie chicken, or sautéed mushrooms and chickpeas. – Zoodle Edition: Use zucchini noodles or hearts of palm pasta for a lower-carb twist. Warm the noodles briefly and toss with sauce off heat.
FAQ
Can I make the sauce ahead of time?
You can make it up to a day in advance. Press plastic wrap directly on the surface and store it in an airtight container in the fridge.
Stir in a squeeze of lemon before serving to refresh the flavor.
What if my avocado isn’t ripe?
It’s worth waiting. An underripe avocado won’t blend smoothly and can taste bitter. If you must proceed, add a bit more olive oil and lemon to help the texture and flavor, but the result won’t be as silky.
Do I need a high-powered blender?
A regular blender or food processor works fine.
If it struggles, add a tablespoon of pasta water and scrape down the sides until the sauce turns smooth.
Is this recipe vegan?
It can be. Replace Parmesan with a vegan Parmesan or 2–3 tablespoons of nutritional yeast, and choose plant-based pasta.
What pasta shape works best?
Spaghetti and linguine are classic, but short shapes like fusilli, rotini, or penne hold onto the sauce beautifully. Whole wheat or gluten-free options also work well.
How do I keep the sauce green?
Use enough lemon juice, minimize air exposure, and avoid direct heat.
If storing, press plastic wrap onto the surface and refrigerate promptly.
Can I freeze avocado pesto?
It’s not ideal. The texture can turn grainy after thawing. If you must, freeze it in small portions with extra lemon and expect a slight color and texture change.
What can I use instead of pine nuts?
Walnuts are the best budget-friendly swap.
Almonds, cashews, or pumpkin seeds also work and each brings a slightly different flavor.
How can I make it higher in protein?
Add grilled chicken, shrimp, sautéed shrimp, crispy tofu, or canned chickpeas. You can also choose a high-protein pasta made from lentils or chickpeas.
Can I serve this cold?
Yes. It works as a chilled pasta salad.
Toss with sauce, add cherry tomatoes and arugula, and chill for 30 minutes before serving.
