A Brief History of Pesto

Pesto alla Genovese hails from Genoa in the Liguria region of northern Italy. The word “pesto” comes from the Italian pestare, meaning “to crush,” because the original recipe was made using a mortar and pestle.

The first written recipes date back to the 1800s, but similar herb-and-nut-based sauces were enjoyed in ancient Rome. The iconic green pesto we know today became widespread thanks to the Genoese seafaring trade, which helped distribute ingredients like olive oil and pine nuts.

What Is Pesto Pasta?

At its simplest, pesto pasta is cooked noodles tossed with pesto sauce. But when done right, it becomes much more:

• Creamy from the emulsification of pasta water and olive oil
• Rich with cheese and nuts
• Bright and herbal from fresh basil

Ideal pasta types include:

• Trofie (traditional in Liguria)
• Fusilli (great for sauce cling)
• Spaghetti or linguine
• Penne (for cold or baked dishes)

How to Make Pesto Pasta: Step-by-Step

Let’s break it down clearly.

Step 1: Cook the Pasta

1. Bring water to a boil, add salt.
2. Cook pasta until al dente. Not sure what that means? Follow this guide on how to boil pasta al dente.
3. Reserve 1 cup of pasta water before draining.

Step 2: Make the Pesto

You can use:

• Mortar and pestle (traditional, deeper flavor)
• Blender or food processor (modern and faster)

Blend:

• Basil, pine nuts, garlic, and cheese until crumbly.
• Slowly drizzle in olive oil until smooth.

Step 3: Combine with Pasta

• Toss hot pasta with pesto.
• Add pasta water little by little while stirring to create a creamy emulsion. Learn how this works in how to marry pasta with sauce.
• Top with extra cheese and black pepper.

Cooking Science: Why Emulsification Matters

Ever wonder why restaurant pesto pasta feels so silky?

That’s thanks to emulsification — the blending of olive oil with starchy pasta water to create a cohesive sauce. Pasta water helps bind the oil-based pesto to the noodles, preventing clumping or dryness.

Pro Tip: Avoid rinsing pasta. It removes surface starch and kills your sauce’s texture!
