Ingredients
- Kosher salt: This flavors the pasta as it cooks For best result use kosher but table salt works
- Spaghetti: Brings satisfying texture Use any shape like linguini or penne if you prefer
- Fresh basil leaves: Signature taste of classic pesto Go for bright green and fragrant leaves
- Garlic cloves: Key to that robust pesto flavor Buy firm fresh garlic heads for best punch
- Toasted pine nuts: Optional but they offer buttery richness Choose golden and fragrant ones for best taste but can swap if needed
- Fresh lemon juice: Brightens and preserves pesto Use real lemon not bottled for clean taste
- Grated Parmesan and Pecorino Romano cheeses: Creamy salty umami Opt for freshly grated for best melt and flavor
- Olive oil: The base of the pesto Use a quality extra virgin for smooth texture and grassy notes
- Black pepper: Freshly ground wakes up all the flavors Use a peppermill if possible
Step-by-Step Instructions
- Boil the Pasta:
- Start by filling a large pot with water and bring it to a rolling boil over high heat Once bubbling vigorously add kosher salt to season the water well Slip in the spaghetti and cook stirring occasionally until al dente according to package timing Just before draining scoop about half a cup of pasta water and set aside then drain the pasta thoroughly
- Make the Pesto:
- While the pasta water heats up pile fresh basil garlic pine nuts kosher salt and pepper into a food processor or blender Pulse the mixture ten to fifteen times just until chopped evenly and rough not pureed This step releases the oils and flavors from the basil and nuts
- Blend in the Good Stuff:
- Add lemon juice cheeses and olive oil right into the basil mixture Blend until the mixture becomes mostly smooth and creamy with flecks of basil Use a spatula to scrape down the sides to make sure everything mixes evenly The pesto should smell fragrant and taste bright at this point
- Toss the Pasta with Pesto:
- Place the drained hot pasta in a large bowl or back in the pot Add the freshly made pesto and toss using tongs or two forks Work quickly so the pasta is still hot helping the pesto cling to every strand If the sauce is thick pour in some of the reserved pasta water a little at a time until each noodle glistens and the sauce looks silky
- Finish and Serve:
- Divide the pasta into bowls and dust with extra grated parmesan for good measure Add a crack of black pepper if you like and serve straight away

I adore the flavor that toasted pine nuts add They make the pesto impossibly rich and buttery Sometimes my son sneaks a handful as I toast them and it always makes us laugh Together we have made this pasta so many times it really is our comfort dish
