This fresh basil pesto pasta combines homemade spinach pasta with a smooth pesto made from basil, walnuts, olive oil, and Parmesan. It’s a simple Italian pasta recipe that feels fresh, vibrant, and satisfying.
Bring a medium pot of water to a rolling boil over medium-high heat and stir in 1 tablespoon salt.
Add 1¼ cups (150 g) 00 flour and 5.3 oz (150 g) baby spinach to a food processor and pulse until a soft dough forms. Transfer the dough to a bowl, lightly dust with flour if needed, and knead for about 1 minute until smooth and elastic. Shape the dough into a disc and flatten it to about ½ inch (1.5 cm) thick.
Hold the dough disc over the boiling water and cut pieces directly into the pot with kitchen scissors. Cook the fresh pasta for about 5 minutes, or until the pasta pieces float to the surface.
While the pasta cooks, add ⅓ cup (50 g) walnuts, 2 garlic cloves, 5 tablespoons (70 ml) extra virgin olive oil, 1 cup (30 g) fresh basil, 1¾ oz (50 g) spinach, 1 oz (30 g) Pecorino cheese, 1¾ oz (50 g) Parmesan Reggiano cheese, juice of ½ lemon, ½ teaspoon salt, and ¼ teaspoon ground black pepper to a food processor and blend until smooth.
Transfer the pesto to a large pan and warm it gently over medium-low heat for about 1 minute. Add the cooked pasta and stir to coat the pasta evenly, adding a small splash of pasta water if needed, until the sauce becomes creamy.
Serve immediately and finish with Parmesan shavings on top.
Notes
Blend the Pesto Smoothly: I like to let the food processor run a little longer so the pesto turns smooth and creamy. This way, I get a sauce that coats the pasta more evenly.Cut the Dough Directly Over the Pot: Holding the dough over the boiling water makes this step much easier. I find that snipping the pasta straight into the pot keeps the process quick and simple.Keep the Pesto Gentle: I always warm the pesto over low heat. If it gets too hot, the basil can lose its fresh color, and the flavor, I think, is not quite as bright.Use a Splash of Pasta Water: A small splash of pasta water helps loosen the pesto beautifully. I like adding a little at a time until the sauce looks silky and coats the pasta well.
