02 - 2 cups fresh basil leaves, packed
03 - 2 cloves garlic
04 - 1/2 cup grated Parmesan cheese
05 - 1/2 cup extra virgin olive oil

→ Creaminess

12 - 1/2 cup heavy cream or unsweetened plant-based cream

# Directions:

01 - Bring a large pot of salted water to a boil. Add pasta and cook according to package instructions until al dente. Reserve 1/2 cup pasta water, then drain pasta.
02 - Toast sunflower seeds in a dry skillet over medium heat for 3–4 minutes until golden and fragrant. Let cool slightly.
03 - In a food processor, combine toasted sunflower seeds, basil, garlic, Parmesan, olive oil, lemon juice, salt, and pepper. Pulse until a coarse paste forms, scraping down sides as needed.
04 - Add water and blend until smooth and creamy. Adjust consistency with more water if needed.
05 - Return drained pasta to the pot over low heat. Add pesto and cream, tossing to coat. Add reserved pasta water a little at a time until the sauce reaches your desired consistency.
06 - Taste and adjust seasoning with salt, pepper, or lemon juice as needed. Serve immediately, garnished with extra Parmesan and fresh basil if desired.

# Expert Suggestions:

01 -
  • Its ridiculously affordable but tastes like something from a fancy Italian restaurant
  • The sunflower seeds create this velvety texture that pine nuts just cant match
  • Ready in 30 minutes but tastes like you spent all afternoon cooking
02 -
  • The water temperature matters. Cold water helps emulsify everything into that silky consistency
  • Over blending can make the pesto bitter. Just pulse until smooth and stop
  • The sauce thickens as it sits, so have that pasta water ready to loosen it up
03 -
  • Make extra pesto and freeze it in ice cube trays for instant weeknight meals
  • Room temperature ingredients blend more smoothly, so pull everything out ahead of time
