Step-by-Step Instructions: Walnut Pesto Pasta
Follow these simple steps to create the perfect Walnut Pesto Pasta:
Prepare the Pesto:
- Toast the Walnuts: Toast the walnuts in a dry skillet over medium heat for 3-5 minutes, stirring frequently, until they become fragrant and lightly browned. This step enhances the walnut flavor and adds a subtle crunch. Set the walnuts aside to cool.
- Blend the Pesto Ingredients: In a food processor or blender, combine the toasted walnuts, fresh basil leaves, garlic, Parmesan cheese (or nutritional yeast for a vegan version), and lemon juice. Pulse several times until the ingredients are roughly chopped.
- Add Olive Oil: With the food processor running, slowly drizzle in the olive oil until the pesto reaches your desired consistency. If the pesto is too thick, add a little more olive oil or a splash of pasta cooking water to thin it out.
- Season to Taste: Add salt, pepper, and crushed red pepper flakes (if using) to the pesto, adjusting the seasoning to your preference. Blend again to incorporate the seasoning.
Cook the Pasta:
- Boil the Pasta: Bring a large pot of salted water to a boil. Add the pasta and cook according to the package directions until al dente, usually around 8-12 minutes, depending on the type of pasta.
- Reserve Pasta Water: Before draining the pasta, reserve about 1/4 cup of the pasta cooking water. This starchy water helps loosen the pesto sauce and allows it to coat the pasta evenly.
- Drain and Toss: Drain the pasta and return it to the pot. Drizzle with a tablespoon of olive oil to prevent sticking. Add the pesto sauce, and toss to coat the pasta evenly. If needed, add a little pasta water to help the pesto sauce adhere to the noodles.
Serve the Pasta:
- Serve: Divide the Walnut Pesto Pasta into individual bowls. Garnish with extra Parmesan cheese, fresh basil leaves, and a sprinkle of crushed walnuts for added texture. You can also add some roasted vegetables or grilled chicken for a more complete meal.
