Homemade basil pesto pasta is one of my favourite meals when I want something fresh and full of flavour without spending a long time in the kitchen. Basil, pine nuts, garlic, Parmesan and olive oil make a fragrant sauce that can be prepared while the pasta cooks.

My first pesto pasta was considerably simpler. I was in my teens, camping with a group of friends, when I stirred a jar of pesto through some pasta and felt rather sophisticated. Everyone enjoyed it, and that meal started my love of pesto. I still appreciate how easy it is, but making the sauce with fresh basil brings a completely different flavour and aroma.

For this version, I use orecchiette and toss the pasta with the pesto once it has cooled very slightly. The pesto remains raw, and the brief pause helps keep the basil a lovely green.

• Fresh basil flavour – Basil is the focus, with pine nuts, garlic and Parmesan adding richness.
• Simple preparation – Make the pesto while the pasta cooks.
• A useful weeknight dinner – It comes together with a short ingredient list and little hands-on cooking.
• Lovely texture – Orecchiette catches the pesto in its small cups.
• No cooked sauce – The pesto is added at the end to preserve its fresh flavour.

Ingredients You’ll Need

Basil

Fresh basil gives the pesto its flavour, fragrance and colour. Use the leaves and discard any tough stems.

Pine Nuts

Toasting the pine nuts brings out their flavour. Watch them closely, as they can colour quickly.

Garlic

A clove of garlic gives the pesto its savoury edge without taking over the basil.

Parmesan

Finely grated Parmesan adds saltiness and depth. Taste the pesto before adding more salt, particularly if your Parmesan is quite salty.

Extra Virgin Olive Oil

The olive oil brings the ingredients together into a sauce that can coat the pasta. Add it according to the quantities in the recipe card, adjusting the final texture if needed.

Orecchiette

I like orecchiette here because the little cups hold onto the pesto, though another pasta shape will also work.

Tips for the Best Pesto Pasta

Toast the pine nuts gently. Remove them as soon as they are lightly golden and let them cool before making the pesto.

Pulse rather than blend continuously. I like a pesto with some texture. Stop and scrape down the sides of the food processor so the ingredients combine evenly.

Taste before adding all the salt. Parmesan contributes saltiness, so it is easier to adjust the finished pesto than to correct one that is too salty.

Let the drained pasta stand briefly. It should still be warm, but no longer piping hot when you add the pesto. I find that very hot pasta can dull the basil’s bright green colour.

Add the pesto just before serving. Toss it through the pasta until evenly coated, then finish with fresh basil and extra Parmesan.

What to Serve with Pesto Pasta

This works well on its own for a simple meal. If you’d like something alongside it, a tomato salad is a natural match; my Caprese Salad is particularly good when tomatoes and basil are in season.

Storage

Pesto pasta is at its best freshly made, when the basil colour and flavour are brightest. If you have leftovers, refrigerate them promptly in an airtight container and eat them within two days. The colour may darken in the refrigerator.

Frequently Asked Questions

Why do you let the pasta cool slightly before adding the pesto?

Pesto is a raw sauce. I find that tossing it with pasta straight from the boiling water can dull the basil’s vibrant colour. I let the drained pasta stand briefly so it is still warm, then add the pesto.

Can I use another pasta shape?

Yes. Orecchiette catches the pesto particularly well, but you can use another short pasta shape you enjoy.

Do I need a food processor?

No. A mortar and pestle will make a more textured pesto. It takes a little longer, but it is a good option if you prefer making it by hand.

Final Thoughts

I’ve come a long way from that jar of pesto on a camping trip, but the appeal of this meal hasn’t changed. It is still straightforward and satisfying. Fresh basil makes this version especially fragrant, and giving the pasta a moment to cool before adding the pesto helps keep the sauce as green as it tastes.
