Vegan pesto pasta is a staple in my kitchen because it’s fast, flexible, and always satisfying. I love how the fresh basil aroma fills the room as I blend the pesto, and the sauce clings to the pasta for a creamy, herby bite every time.

This dish comes together quickly, making it perfect for busy weeknights or relaxed weekend dinners. I often serve it warm as a main course, but it’s just as good at room temperature for lunches or picnics.

The texture is comforting: tender pasta coated in a silky, nutty sauce with little bursts of garlic and lemon. It’s a recipe I return to often, especially when I want something that feels special but doesn’t take much effort.

It’s also a great way to use up extra greens or herbs, and the leftovers taste just as good the next day. This pasta is a crowd-pleaser, whether I’m cooking for vegans or anyone who loves bold, fresh flavors.

• 12 oz (340 g) dried pasta (spaghetti, fusilli, or penne)
• 2 packed cups fresh basil leaves (about 2 oz)
• 1/3 cup raw cashews or pine nuts
• 2 garlic cloves
• 1/4 cup nutritional yeast
• 1/2 teaspoon fine sea salt, plus more for pasta water
• 1/4 teaspoon black pepper

Step-by-Step Instructions

This recipe comes together in just a few steps. While the pasta cooks, blend the pesto ingredients until smooth. Toss the hot pasta with the pesto and any add-ins, then serve immediately or at room temperature.

1. Bring a large pot of salted water to a boil. Cook the pasta according to package instructions until al dente. Reserve 1/2 cup pasta cooking water, then drain.
2. While the pasta cooks, combine basil, cashews or pine nuts, garlic, nutritional yeast, salt, pepper, and lemon juice in a food processor or blender.
3. Pulse until the mixture is finely chopped.
4. With the machine running, slowly stream in the olive oil and 1/4 cup cold water. Blend until smooth and creamy, scraping down the sides as needed.
5. Taste and adjust seasoning with more salt, pepper, or lemon juice if desired.
6. Return the drained pasta to the pot. Add the pesto and 2–4 tablespoons reserved pasta water. Toss well to coat, adding more water as needed for a silky sauce.
7. If using, fold in cherry tomatoes.
8. Serve immediately, topped with extra basil or a sprinkle of red pepper flakes if desired.
