Equipment
- food processor
- large pot
- measuring cups
- measuring spoons
- tongs
- long spoon
- heatproof measuring cup
- colander
- large serving bowl
Ingredients
Pasta
- 1 pound spaghetti or linguine
- 1 tablespoon salt for pasta water
Pesto Sauce
- 2 cups fresh basil leaves packed
- 1/2 cup pine nuts
- 2 cloves garlic peeled
- 1/2 cup Parmesan cheese freshly grated
- 1/2 teaspoon fine sea salt
- 1/4 teaspoon black pepper freshly ground
- 1/2 cup extra virgin olive oil
Instructions
- In the bowl of a food processor, combine the packed fresh basil leaves, pine nuts, peeled garlic cloves, freshly grated Parmesan cheese, 1/2 teaspoon of fine sea salt, and 1/4 teaspoon of freshly ground black pepper. Pulse the mixture several times until the ingredients are finely chopped and combined. With the food processor running on low, slowly stream in the 1/2 cup of extra virgin olive oil until a smooth, vibrant green paste forms. Set the pesto aside.
- Fill a large pot (at least a 6-quart capacity) with 4 quarts of cold water. Add 1 tablespoon of salt to the water. Place the pot over high heat and bring the water to a rapid, rolling boil.
- Add the 1 pound of spaghetti to the boiling water, stirring occasionally with tongs or a long spoon to prevent the strands from sticking together. Cook the pasta according to the package directions, typically for 8 to 10 minutes, until it is al dente (tender but still firm to the bite).
- Before draining the pasta, carefully scoop out 1 cup of the hot, starchy pasta cooking water using a heatproof measuring cup. This reserved water is crucial for helping to emulsify the pesto into a smooth, creamy sauce.
- Drain the cooked pasta thoroughly in a colander, shaking gently to remove excess water. Do not rinse the pasta, as the residual starch on the noodles helps the pesto cling better.
- Immediately transfer the hot, drained pasta to a large serving bowl. Add all of the prepared pesto to the pasta. Pour in 1/4 cup of the reserved pasta water. Using tongs, toss the pasta vigorously until it is evenly coated with the pesto and the sauce appears creamy and well-distributed. If the sauce seems too thick, add more reserved pasta water, 1 tablespoon at a time, until the desired consistency is reached.
- Serve the pesto pasta warm, garnished with additional freshly grated Parmesan cheese or a few fresh basil leaves, if desired.

My Pro Tips for Perfect Pesto Pasta
- Use Fresh Ingredients: The quality of your basil and Parmesan directly impacts the final flavor of your Italian pasta dish.
- Don’t Rinse the Pasta: The starch left on the noodles helps the garlic basil sauce adhere beautifully.
- Emulsify with Pasta Water: Adding the starchy water gradually helps create a creamy, restaurant-quality sauce.
- Toss While Hot: Combine the pasta and pesto immediately after draining for the best absorption. For another pasta dish that relies on perfect timing, check out my hibachi noodles recipe.
How to Keep Your Pesto Pasta Fresh
- Store: Place leftovers in an airtight container in the refrigerator for up to 4 days. The pesto may darken, which is natural.
- Freeze: Freeze pesto sauce alone (without pasta) in an ice cube tray for up to 3 months for quick future meals.
- Reheat: Gently warm in a skillet over low heat with a splash of water or olive oil to revive the sauce.
- Make-Ahead Tip: You can make the pesto sauce up to 3 days in advance and store it in the fridge with a layer of oil on top.
Frequently Asked Questions
How do you keep pesto pasta from drying out?
The key is using the reserved starchy pasta water. When tossing the hot pasta with the pesto, add the water a little at a time until the sauce becomes creamy and clings to the noodles. If your leftovers seem dry when reheating, add a tablespoon of water or olive oil.
What is the best pasta for pesto?
Long, flat pasta like spaghetti, linguine, or fettuccine are ideal because their surface area helps the pesto coat evenly. Shapes like fusilli or penne are also great as their nooks and crannies trap the sauce beautifully.
Can I make pesto without a food processor?
Yes, you can make a traditional pesto using a mortar and pestle for a more textured, authentic result. A high-powered blender will also work, though you may need to scrape down the sides more frequently to ensure an even blend.
Why did my pesto turn brown?
Pesto can oxidize and turn brown when exposed to air. To prevent this, press a piece of plastic wrap directly onto the surface of the pesto before storing it, or add a thin layer of olive oil on top. It’s still safe to eat if it darkens.
