🌿 What is Pesto alla Genovese?

“Pesto” comes from the Italian word pestare, meaning “to pound” or “crush”—a nod to how the sauce was originally made. While modern kitchens often use food processors, the essence of pesto remains the same: fresh, raw ingredients blended into a fragrant, creamy paste.

Pesto alla Genovese is the most famous type of pesto, and it’s named after Genoa, the capital of Liguria in north-west Italy. It’s best known for being paired with trofie or linguine pasta, but works equally well with gnocchi, new potatoes, or even stirred into soups.

🧄 Step-by-Step Instructions

1. Prepare the Ingredients

Wash and gently pat the basil leaves dry with kitchen paper. Make sure they are dry before blending—excess water can dilute the sauce and affect its texture.

Toast the pine nuts lightly in a dry pan over medium heat for 1–2 minutes, stirring frequently until golden. This brings out a nutty depth but is optional if you prefer a milder flavour.

2. Traditional Method (with Pestle and Mortar)

Start by crushing the garlic and a pinch of salt in the mortar. Add the basil leaves gradually, grinding them in circular motions to release the oils and aromas.

Next, add the pine nuts and continue grinding. Stir in the grated cheeses, and finally, slowly drizzle in the olive oil while mixing until a thick, glossy paste forms.

3. Modern Method (with Food Processor)

Place the garlic, basil leaves, pine nuts, and a pinch of salt in the food processor. Pulse until finely chopped.

Add the grated cheeses and pulse a few more times. Then, with the processor running on low, slowly drizzle in the olive oil until the mixture is smooth and emulsified. Taste and adjust seasoning if needed.

Tip: Add a teaspoon of lemon juice to keep the colour bright if you're not using the pesto immediately.

🍝 How to Use Pesto alla Genovese

With Pasta: Toss pesto with freshly cooked pasta (like trofie, linguine, or spaghetti). Add a splash of pasta water to loosen the sauce and help it coat the pasta evenly.

Spread: Use it as a sandwich spread, or stir into mayonnaise or yoghurt for a herby dip.

Drizzle: Over roasted vegetables, grilled chicken, or fish.

Soup Stir-in: Add a spoonful to minestrone for a Ligurian twist.

🔁 Storage Tips

Store pesto in an airtight jar in the fridge for up to 5 days. Cover the surface with a thin layer of olive oil to prevent oxidation.

For longer storage, freeze in an ice cube tray and transfer the frozen cubes to a freezer bag. Use directly from frozen in hot dishes.

👨‍🍳 Cooking Tips

Use young, small basil leaves for the best flavour and texture. Older leaves can be bitter.

Always grate your cheese fresh—pre-grated cheese often contains anti-caking agents that affect the texture.

Avoid over-blending if using a food processor; too much heat can dull the basil’s flavour and colour.
