Jump to Recipe

This vegan pesto pasta blends basil, cashews, garlic, olive oil and nutritional yeast into a savoury sauce. The source says “live yeast”; this is interpreted as nutritional yeast, which adds a cheesy flavour without acting as a leavener. Reserve pasta water to loosen the pesto and help it cling. Blend the sauce briefly so it stays bright green, then toss with hot pasta off the heat. Boil pasta in salted water according to package directions until al dente. Reserve a cup of pasta water, then drain. Blend basil, cashews, garlic, nutritional yeast, olive oil, lemon juice, salt and pepper until mostly smooth. Add a spoonful of pasta water and blend briefly until pesto is loose but still coats a spoon.
