Understanding Pesto and Its Origins
Before jumping into the recipe, it's helpful to understand what pesto is and its cultural roots. Pesto originates from Genoa, in the Liguria region of Italy. Traditionally, it is a vibrant green sauce made from fresh basil, pine nuts, garlic, Parmesan cheese, olive oil, and sometimes lemon juice. The word "pesto" derives from the Italian verb "pestare," meaning "to crush" or "to pound," referring to the traditional method of grinding ingredients with a mortar and pestle.
While the classic basil pesto is the most popular, there are many variations such as sun-dried tomato pesto, arugula pesto, or vegan pesto made without cheese. For the purpose of this recipe, we'll focus on the traditional basil pesto, which pairs beautifully with spaghetti.

Step-by-Step Instructions for Making Spaghetti with Pesto Sauce
1. Prepare the Pesto Sauce
Creating a flavorful pesto requires a good mortar and pestle or a high-speed blender. The traditional method involves crushing the basil, garlic, and pine nuts together, then adding cheese and olive oil.
Using a mortar and pestle:
1. Place the garlic and a pinch of salt into the mortar and pound until minced.
2. Add the pine nuts and continue grinding until the mixture is coarse.
3. Add the basil leaves gradually, crushing and turning until a bright green paste forms.
4. Mix in the grated Parmesan cheese.
5. Slowly drizzle in the olive oil while stirring or grinding until the sauce reaches your desired consistency.
6. Taste and adjust salt or lemon juice if needed.
Using a blender or food processor:
1. Combine basil, garlic, pine nuts, and cheese in the processor.
2. Pulse a few times to combine.
3. With the machine running, slowly pour in olive oil until smooth.
4. Stop and scrape down the sides as needed.
5. Season with salt and lemon juice to taste.
2. Cook the Spaghetti
1. Fill a large pot with water and bring to a boil.
2. Add a generous amount of salt (about 1-2 tablespoons).
3. Add the spaghetti and cook according to package instructions until al dente (firm to the bite).
4. Reserve about 1 cup of pasta water before draining.
5. Drain the spaghetti and set aside.
3. Combine Pasta and Pesto
1. Return the drained spaghetti to the pot or a large mixing bowl.
2. Add the pesto sauce directly over the hot pasta.
3. Toss gently to coat all strands evenly.
4. If the sauce is too thick, add a little reserved pasta water, a tablespoon at a time, to loosen it and help it cling to the spaghetti.
4. Serve and Garnish
1. Plate the spaghetti with pesto in individual bowls or a serving platter.
2. Sprinkle additional grated Parmesan cheese on top.
3. Garnish with fresh basil leaves or a drizzle of quality olive oil for extra flavor.
4. Serve immediately for the best taste.
