There’s a quiet joy in crafting this dish, especially when I gather bits of basil, parsley, or whatever greens are lingering in the fridge. Blending them into a bright, oily pesto feels like a small act of eco-consciousness, and the aroma alone—garlicky, herby, with a nutty undertone—is worth the effort. It’s a gentle reminder that simple ingredients can make magic.

Ingredient breakdown

Fresh basil: I love the vibrant, sweet aroma it releases when blended, almost like a garden in bloom. Use what you have, but don’t skip it—it’s the star.
Toasted pine nuts: I prefer tossing them in a dry skillet until golden and fragrant, giving the pesto a rich, smoky depth. If unavailable, walnuts work but lack that buttery punch.
Garlic: I smash and chop it finely to release its pungent, aromatic oils. If it’s too strong, a quick blanch can mellow it out—just don’t overdo it.
Olive oil: I drizzle until the pesto feels silky and smooth—start with less, then add as needed for that luscious texture. Opt for a good quality, peppery variety for extra zing.
Lemon juice: I squeeze in fresh for brightness, making the pesto zing with citrus. Skip or reduce if you prefer milder, more herbal notes—though I swear, it’s the lemon that lifts everything.
Nutritional yeast: I toss this in for cheesy, umami flavor without dairy. It’s a game-changer, but if you’re out, a pinch of miso paste can mimic that salty depth.
Salt and pepper: I season gradually, tasting as I go. The right balance makes all the difference—don’t be shy to crank it up for that final flavor punch.

Step-by-step guide to vegan pesto pasta

Gather your equipment: a large pot, a blender or food processor, a skillet, and a mixing bowl. Boil water in the pot until it reaches rolling boil (~100°C / 212°F).
Cook the pasta: add a generous pinch of salt, then drop the pasta in. Cook for 8-10 minutes until al dente, stirring occasionally. Test a piece for firmness.
While pasta cooks, toast nuts: place pine nuts or walnuts in a dry skillet over medium heat (~160°C / 320°F). Stir frequently, toast until golden and fragrant (~3-4 mins). Set aside to cool.
Make the pesto: in the blender, combine fresh herbs, toasted nuts, garlic, lemon juice, nutritional yeast, a pinch of salt and pepper. Blend while drizzling in olive oil until smooth and bright green. Check consistency—add more oil if needed.
Drain the pasta, reserving a cup of pasta water. Return pasta to the pot or a large mixing bowl.
Toss pasta with pesto: add a few spoonfuls at a time, stirring to coat evenly. If the sauce feels thick, loosen with a splash of reserved pasta water until silky.
Finish with a squeeze of lemon and a crack of black pepper. Taste and adjust salt or lemon if needed.
Rest briefly: let the pesto pasta sit for 2 minutes to allow flavors to meld. Then, serve immediately, garnished with extra herbs or nuts if desired.
