Cook with confidence
Cook's notes
Cook the pasta until al dente, as it will continue to cook slightly when mixed with the pesto. The creamy texture of the sauce comes from the emulsification of the olive oil and cheese, so be sure to mix thoroughly to achieve a smooth consistency. If the sauce is too thick, add a splash of pasta water to loosen it up.
Substitutions
If you don't have pine nuts, walnuts or sunflower seeds can be used as a substitute for a similar crunch. For a dairy-free version, nutritional yeast can replace Parmesan cheese, but it will alter the flavor profile slightly. You can also use any long pasta like fettuccine or tagliatelle instead of spaghetti or linguine.
Storage & leftovers
Store any leftovers in an airtight container in the refrigerator for up to 3 days. When reheating, add a little olive oil or water to help revive the creamy texture, as the sauce may thicken in the fridge. Avoid reheating in the microwave for best results; instead, warm gently on the stove over low heat.
Common failures
A common failure is overcooking the pasta, which can lead to a mushy texture that won't hold the sauce well. If the pesto turns out too bitter, it may be due to over-blending the basil or using old nuts; always toast fresh nuts lightly to enhance their flavor. If the sauce separates, it may be a sign of too much oil; try blending it again with a bit of pasta water to bring it back together.
Why these ingredients
How each main ingredient earns its place in this recipe
-
fresh basil leaves
Basil is the star of the dish, providing a fresh, aromatic flavor that defines the pesto. Using 2 cups ensures a vibrant green color and a robust herbal taste that permeates the entire dish.
-
Parmesan cheese
Parmesan adds a creamy richness and umami depth to the sauce, with 1/2 cup contributing to the emulsification process that gives the pesto its signature texture. Its saltiness also enhances the overall flavor profile.
-
pine nuts
Toasted pine nuts add a subtle crunch and nutty flavor that complements the creaminess of the pesto. Using 1/3 cup helps balance the sauce's texture and provides a contrasting bite to the smooth pasta.
-
extra virgin olive oil
The olive oil acts as the base of the creamy sauce, with 1/2 cup helping to emulsify the ingredients and create a silky mouthfeel. It also adds a fruity richness that enhances the overall flavor of the dish.
Preparation
-
Step 1 12 min
Bring a large pot of heavily salted water to a rolling boil. Add the spaghetti or linguine and cook according to package instructions until al dente, usually about 12 minutes. Stir occasionally to prevent sticking. Once cooked, drain the pasta, reserving half a cup of the starchy pasta water for later use.
-
Step 2 5 min
While the pasta is boiling, prepare the pesto. In a food processor, combine the fresh basil leaves, grated Parmesan cheese, toasted pine nuts, minced garlic, extra virgin olive oil, salt, and black pepper. Blend the mixture until it forms a smooth, vibrant green paste, which should take about 5 minutes. Scrape down the sides as needed to ensure everything is well combined.
-
Step 3
In a large mixing bowl, combine the hot cooked pasta with the freshly made basil pesto. Toss the pasta thoroughly to ensure it is evenly coated with the sauce. If the pesto is too thick, add a splash of the reserved pasta water to create a creamy, emulsified coating. Continue to toss until the pasta is well coated and the sauce clings beautifully to each strand.
-
Step 4
Taste the pasta and adjust the seasoning if necessary, adding more salt or pepper to suit your preference. If desired, you can also add more grated Parmesan cheese for extra flavor.
-
Step 5
Serve the creamy basil pesto pasta immediately while it's hot. You can garnish with additional pine nuts, a drizzle of olive oil, and a sprinkle of Parmesan cheese for an appealing presentation.

Step 6
For a complete meal, consider pairing this dish with a side salad or some crusty bread to soak up any remaining pesto sauce. Enjoy your delicious and vibrant pasta dish!
