Bring a large pot of water with a generous amount of sea salt to a boil. Add pasta and cook until just al dente, about 8–10 minutes according to package instructions. Reserve 1/2 cup of cooking water before draining.

While pasta cooks, combine avocados, basil leaves, toasted pine nuts, garlic cloves, olive oil, lemon juice, salt, and black pepper in a food processor. Pulse until smooth and creamy, scraping down sides as needed. The mixture should be thick yet spreadable. If too thick, blend in an additional 1 tablespoon olive oil.

Return drained pasta to the warm pot. Add the avocado pesto and toss until each strand is evenly coated. If sauce is overly thick, add reserved pasta water a tablespoon at a time, tossing after each addition, until desired creamy consistency is reached.

Divide pasta into serving bowls. Top with extra basil leaves and freshly ground black pepper. Optionally, garnish with halved cherry tomatoes for added color and acidity. Serve immediately while hot.
