Creamy Sunflower Seed Pesto Pasta (Printable)

Toasted sunflower seeds create a rich, nutty pesto tossed with pasta and cream for a comforting vegetarian meal.

# What You’ll Need:

→ Pesto Components

01 - 1 cup unsalted sunflower seeds, toasted
02 - 2 cups fresh basil leaves, packed
03 - 2 cloves garlic, peeled
04 - 1/2 cup grated Parmesan cheese
05 - 1/2 cup extra virgin olive oil
06 - 1/4 cup water, plus more as needed
07 - 2 tablespoons fresh lemon juice
08 - 1/4 teaspoon kosher salt
09 - 1/4 teaspoon freshly ground black pepper

→ Pasta

10 - 14 ounces dried pasta (spaghetti, penne, or fusilli)
11 - 1 tablespoon salt for pasta water

→ Finishing

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

# How-To Steps:

01 - Heat a dry skillet over medium heat. Add sunflower seeds and toast for 3-4 minutes, stirring frequently until golden and fragrant. Remove from heat and let cool for 2-3 minutes.
02 - Combine toasted sunflower seeds, basil, garlic, Parmesan, olive oil, lemon juice, salt, and pepper in a food processor. Pulse until a coarse paste forms, scraping down the sides as needed. Add 1/4 cup water and blend until smooth and creamy, adding additional water 1 tablespoon at a time if needed to reach desired consistency.
03 - Bring a large pot of salted water to a boil. Add pasta and cook according to package directions until al dente, typically 8-10 minutes. Reserve 1/2 cup of the starchy pasta water before draining.
04 - Return the drained pasta to the warm pot over low heat. Pour in the prepared pesto and heavy cream. Toss vigorously with tongs to coat the pasta evenly. Add the reserved pasta water a little at a time, tossing continuously, until the sauce becomes glossy and clings to the pasta.
05 - Taste the pasta and adjust seasoning with additional salt, pepper, or lemon juice as needed. Transfer to serving plates or bowls. Serve immediately while hot, optionally garnished with additional grated Parmesan and fresh basil leaves.

# Expert Tips:

01 -

  • The creamy texture coats every strand of pasta perfectly, making each bite incredibly satisfying
  • It comes together in under 30 minutes, making it perfect for weeknight dinners when comfort food is nonnegotiable
02 -
  • Let the toasted sunflower seeds cool for a few minutes before blending, otherwise they can turn the basil brown and bitter from the heat
  • The reserved pasta water is absolutely crucial for getting that silky, restaurant quality texture that clings to every strand
03 -
  • Make double the pesto and freeze half in ice cube trays for future quick weeknight meals
  • If the sauce seems too thick after tossing, add pasta water one tablespoon at a time until it is perfectly glossy and coating every piece
