Step-by-Step Instructions

Follow these simple steps to create your walnut pesto pasta salad. It’s quick, easy, and guaranteed to impress.

1. Cook the Pasta: Bring a large pot of salted water to a boil over high heat. Cook the pasta according to the package instructions, then drain it and rinse with cold water to stop the cooking process.
2. Prepare the Pesto: While the pasta cooks, combine the basil, parsley, walnuts, Parmesan cheese, garlic, lemon juice, salt, and pepper in a food processor. Pulse the mixture until finely chopped, scraping down the sides as needed.
3. Add Olive Oil: With the food processor running, slowly drizzle in the olive oil until the pesto becomes smooth and well combined. Taste and adjust seasoning if necessary.
4. Toss Everything Together: Transfer the prepared pesto to a large mixing bowl. Add the cooked pasta, chopped tomato, and roasted red peppers. Toss until the pasta is evenly coated with the pesto.
5. Serve and Enjoy: Garnish with additional basil leaves if desired and serve immediately. You can also refrigerate the salad for up to 1 day and serve chilled.

Our Top Tips for Perfect Results

Here are a few tips from our kitchen to ensure your walnut pesto pasta salad turns out perfectly every time:

• Use Fresh Ingredients: For the best flavor, choose fresh basil, parsley, and a high-quality olive oil.
• Cool the Pasta: Rinsing the cooked pasta with cold water not only cools it down but also prevents it from sticking together.
