Easy Creamy Pesto Pasta
This pesto pasta is a vibrant, herbaceous masterpiece made from fresh basil, pine nuts, and Parmesan cheese that transforms simple ingredients into a luxuriously creamy sauce. It comes together in just 30 minutes, making it the perfect quick weeknight dinner or an impressive dish for casual entertaining.
My love for this easy pesto pasta began during a summer spent in Liguria, the birthplace of pesto, where the scent of fresh basil hung heavy in the air. I was captivated by how a few humble ingredients could create something so profoundly flavorful and satisfying. Now, I make this creamy pesto pasta regularly for my family, often pairing it with a simple green salad or serving it alongside my creamy tomato gnocchi for a larger Italian-inspired feast. It’s a dish that always feels like a warm embrace, whether I’m serving it on a busy Tuesday or for a relaxed weekend lunch with friends. For a cozy, plant-based twist, my vegan pesto pasta is another favorite in my recipe collection.

Ingredients
Pasta
- 1 pound spaghetti or linguine
- 1 tbsp fine sea salt for pasta water
Pesto
- 2 cups fresh basil leaves packed
- 1/2 cup pine nuts
- 2 cloves garlic peeled
- 1/2 cup freshly grated Parmesan cheese
- 1/2 tsp fine sea salt
- 1/4 tsp freshly ground black pepper
- 1/2 cup extra virgin olive oil
Equipment
- food processor
- large pot
- tongs
- colander
- heatproof measuring cup
- large serving bowl
- measuring cups
- measuring spoons
Method
- 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.
Ways to Customize Your Pesto Pasta
- Chicken Pesto Pasta: Add sliced grilled chicken breast for a protein-packed, complete meal.
- Pesto Pasta with Vegetables: Stir in roasted cherry tomatoes, sautéed mushrooms, or steamed broccoli florets.
- Vegan Pesto Pasta: Substitute nutritional yeast for Parmesan and ensure your pasta is egg-free.
My Favorite Tips for Perfect Results
- Reserve Pasta Water: The starchy liquid is the secret to achieving a creamy, emulsified sauce that clings to every noodle.
- Toast Your Nuts: Lightly toasting the pine nuts in a dry pan enhances their flavor significantly.
- Don’t Rinse the Pasta: The starch left on the noodles helps the sauce adhere better for the best pesto pasta.
- Emulsify Thoroughly: Toss the pasta and pesto vigorously with tongs to create a smooth, cohesive creamy pesto pasta sauce. For another creamy dish, try my creamy mushroom pappardelle.
How to Store and Reheat Your Pesto Pasta
- Store: Keep leftovers in an airtight container in the refrigerator for up to 3 days. The sauce may darken, but the flavor remains excellent.
- Freeze: Freeze pesto pasta without added garnish in a freezer-safe container for up to 2 months. Thaw overnight in the refrigerator.
- Reheat: Gently warm in a skillet over low heat with a splash of water or broth to loosen the sauce, stirring frequently.
- Make-Ahead Tip: The pesto sauce can be made up to 3 days in advance and stored in the fridge with a layer of olive oil on top to prevent browning.
Frequently Asked Questions
Can I make pesto pasta without a food processor?
Yes, you can use a blender or even a mortar and pestle for a more traditional texture. The key is to chop the basil and nuts very finely before slowly incorporating the oil.
How do I prevent my pesto from turning brown?
The basil oxidizes when exposed to air. Adding a thin layer of olive oil on top of stored pesto and using it quickly helps maintain its vibrant green color.
What can I use instead of pine nuts in pesto?
Toasted walnuts, almonds, or even sunflower seeds make excellent, often more affordable, substitutions for pine nuts in a homemade pesto sauce.
Is pesto pasta served hot or cold?
This particular recipe is best served warm, right after tossing. The heat helps the sauce coat the pasta beautifully. For a cold dish, you would make a pesto pasta salad.
