Ingredients
  

For the Sauce
  • 2 large ripe Hass avocados ~300g flesh
  • 2 tablespoons fresh lemon juice 30ml
  • 2 medium garlic cloves minced (~6g)
  • ¼ cup extra virgin olive oil 60ml
  • ½ cup fresh basil leaves packed (~20g)
  • 1 teaspoon kosher salt 6g
  • ½ teaspoon black pepper 1g
  • ½ –¾ cup reserved pasta water 120–180ml
For the Pasta
  • 12 oz pasta of choice - fettuccine linguine, or penne (340g)
  • Water for boiling
  • 1 tablespoon salt for pasta water
Optional Garnish
  • ¼ teaspoon red pepper flakes
  • ¼ cup grated Parmesan cheese 25g - omit for vegan
  • Extra fresh basil leaves
  • Drizzle of extra virgin olive oil
  • Cracked black pepper

Equipment

  • High-speed blender (Vitamix or NutriBullet recommended)
  • Large pot for boiling pasta
  • Colander
  • Large mixing bowl
  • Whisk
  • Tongs or pasta fork
  • Measuring cups and spoons
  • Chef's knife and cutting board

Method
 

Step 1 - Cook the Pasta
  1. Bring a large pot of water to a rolling boil. Add 1 tablespoon of salt—the water should taste like the sea. Add pasta and cook for 1 minute less than package directions for al dente. Before draining, reserve 1 full cup of pasta water. Drain pasta and set aside.
Step 2 - Check Avocado Ripeness
  1. Halve the avocados and remove pits. The flesh should yield easily to a spoon and be bright green without brown streaks. Scoop the flesh into a high-speed blender.
Step 3 - Blend the Sauce
  1. Add avocado flesh, lemon juice, minced garlic, basil leaves, olive oil, salt, and black pepper to the blender. Add ¼ cup of the reserved pasta water. Blend on high speed for 30-45 seconds until completely smooth and creamy. The sauce should ribbon off a spoon.
Step 4 - Adjust Consistency
  1. Transfer sauce to a large mixing bowl. Add another ¼ cup of warm pasta water and whisk gently to loosen. The sauce should be slightly thinner than you want the final result—it will thicken when it coats the pasta. Taste and adjust salt and lemon as needed.

Step 6 - Serve Immediately
  1. Plate the pasta right away. Garnish with torn fresh basil, a drizzle of olive oil, cracked black pepper, and optional Parmesan. Serve within minutes for the best color and flavor.

Notes

Critical Success Tips:
  • Ripeness matters: Under-ripe avocados create grainy, bitter sauce. Over-ripe causes separation.
  • Never heat the sauce: Add to pasta off-heat only. Direct heat breaks the emulsion and turns fats bitter.
  • Fresh lemon only: Bottled juice lacks the aromatic oils needed to preserve color and flavor.
  • Use immediately: This sauce oxidizes quickly. It's not a make-ahead recipe.
The Plastic Wrap Trick:
If you must store sauce for 2-4 hours, press plastic wrap directly onto the surface to eliminate air exposure. Add a few drops of fresh lemon juice on top before sealing.
Pasta Water is Essential:
The starch in pasta water acts as an emulsifier, helping the sauce cling to pasta. Don't skip this step.
Best Pasta Shapes:
Fettuccine, linguine, penne rigate, rigatoni, or any shape with texture/surface area.
Protein Boost:
Use Banza chickpea pasta or Barilla Protein+ for extra protein and fiber.
Scaling:
This recipe scales perfectly. For 2 servings: use 1 large avocado, 1 tablespoon lemon juice, 4 oz pasta.
