Ingredients needed

The full list of ingredients for this easy recipe are listed fully down in the recipe card but let’s briefly go over the pantry staples needed including a few substitutions you can make as desired!

Spaghetti – or any pasta you like; linguine, penne, and rigatoni all work great here

Fresh basil leaves– sweet basil is classic; sub in some spinach or parsley if you’re running low Pine nuts – toast them for the best flavor; walnuts or cashews work as a budget-friendly swap

Parmesan cheese – freshly grated melts in better; Pecorino Romano is a good swap for a saltier bite

Garlic – anywhere from 1-5 cloves depending on how bold you want it

Lemon juice – keeps the pesto bright green and adds a little freshness

Extra virgin olive oil – the base of the sauce, so use one you actually like

How to Make It

Just a reminder that you can find the FULL written homemade pesto pasta recipe down in the recipe card, but I want to quickly go over how to make them with visuals for you 🙂

Cook your pasta in a medium pot according to package directions until al dente. Reserve some of the pasta cooking water in case you want to thin your pesto at all. Drain the pasta and set aside.

While the pasta cooks, make the pesto by combining the ingredients in a large food processor. Blend the toasted pine nuts, garlic cloves, and lemon juice. Then add in the basil and parmesan and pulse about 10 times. With the food processor running, slowly drizzle in the olive oil until emulsified.

Add a little more olive oil as desired to get the pesto to your desired consistency. You can also add in a bit of pasta water to thin it out as desired.

Toss the drained pasta with the basil until fully combined. Serve with fresh basil, black pepper, red pepper flakes, and additional parmesan + pine nuts. Enjoy!

Recipe Tips

Reserve a cup of pasta water before draining – a splash of that starchy water makes the pesto cling to every strand instead of pooling at the bottom of the bowl.

Toss the pasta with pesto off the heat so the sauce stays bright and doesn’t oxidize.

Toast the pine nuts! – it only takes 3 minutes and adds a depth of flavor that makes the whole dish taste more complex. Trust me!

Don’t over-blend the pesto; a little texture is a good thing.

Add a thin layer of olive oil on top of any leftover pesto to keep it from browning in the fridge.

Add cherry tomatoes and diced mozzarella to make this a simple pesto pasta salad!

Frequently Asked Questions

Can I use store-bought pesto?

You can, but homemade makes a noticeable difference here – it’s brighter, fresher, and takes only 10 minutes.

What pasta shape is best for pesto?

Spaghetti is classic, but long noodles like linguine or short shapes like fusilli (which grabs sauce in the ridges) work great too.

Can I add protein?

Totally – this is great with white beans, chickpeas, grilled tofu, or a soft-boiled egg on top. If you’re not vegetarian, you could add chicken or shrimp!

How do I keep pesto from turning brown?

A squeeze of lemon juice in the pesto helps, and topping any stored pesto with a thin layer of olive oil keeps it from oxidizing.

Ingredients

12 oz pasta I used spaghetti½ cup pine nuts toasted3-4 cloves garlic*1 lemon juiced (about 2-3 tablespoons)3 cups fresh basil leaves tightly packed cup parmesan cheese grated or shredded cup extra virgin olive oil plus more as desiredFor serving: extra parmesan, pine nuts, and fresh basil

Instructions

Cook the pasta according to package directions. Reserve 1 cup of the pasta water. Drain and set aside.
(Optional but highly recommended): Toast the pine nuts in a dry skillet for a few minutes until they start to darken in color. This step is totally optional and I’ve made pesto many times without toasting the nuts. But I love the extra flavor.
Meanwhile, make the pesto. Add the pine nuts, garlic, and lemon juice to the bowl of a food processor and pulse until they are broken up – about 10 times. Next, add the basil and parmesan and pulse until the basil is broken into small pieces – about 10 pulses.
With the food processor on low speed, slowly drizzle in ⅓ cup of olive oil. Add more olive oil as desired for a smoother consistency. Season with salt and pepper to taste.
Toss the cooked pasta with the pesto, adding the reserved pasta water, a small splash at a time, until you reach your desired consistency. I usually add just a couple tablespoons of pasta water. You can leave it out completely as desired. Enjoy!

Notes

Garlic – you can leave it out all together or just add in as much as you’d like. I typically like a lot but anywhere between 1-5 cloves would work well.

Pine nuts – toast the pine nuts in a dry skillet over medium heat until they start to darken in color, just a few minutes. Watch them closely so they don’t burn. 

Storage + Reheating – Leftover pesto pasta keeps in an airtight container in the fridge for up to 4 days. When reheating, add a small splash of water or olive oil and warm it gently on the stovetop or in the microwave – the pasta tends to absorb the sauce as it sits, so the extra liquid brings it right back. The pesto itself can be stored separately for up to a week in the fridge (with that olive oil layer on top) or frozen for up to 6 months.
