What Is Pesto?
Pesto sauce (pesto alla Genovese) is one of Italy’s most famous sauces, originating in Liguria, from the city of Genoa. Its name comes from the Italian word pestare, meaning “to pound” — because authentic pesto is traditionally made in a marble mortar, grinding the ingredients with a wooden pestle.
Classic basil pesto combines fresh greens, pine nuts, garlic, hard cheese and olive oil. Today the sauce has countless variations and is used not only for pasta, but also for meat, fish, vegetables, pizza and even soups.
Health Benefits of Pesto
Pesto is not just a delicious sauce — it is also a source of valuable nutrients:
- Basil — antioxidants, essential oils, vitamins A, K, C.
- Extra Virgin olive oil — healthy fats that support the heart and blood vessels.
- Pine nuts — plant protein, magnesium, vitamin E.
- Cheese (parmesan, pecorino) — calcium, protein, amino acids.
- Garlic — a natural antiseptic that strengthens immunity.
Adding pesto regularly to your diet helps balance nutrition, enriches dishes with vitamins and gives them an unmistakable aroma.
Classic Pesto Recipe
Ingredients (makes ~200 ml):
- 50 g fresh basil
- 30 g pine nuts
- 40 g parmesan
- 20 g pecorino
- 100 ml Extra Virgin olive oil
- 1 clove of garlic
- A pinch of sea salt
Method:
- Wash and dry the basil leaves.
- In a mortar or blender, crush the garlic with the nuts.
- Add the basil and salt, pound to a paste.
- Mix in the grated cheeses.
- Pour in the oil in a thin stream, stirring continuously.
👉 The classic recipe does not use lemon juice. However, modern chefs add a few drops to keep the sauce a vivid green and give it a fresh edge.
Why Does Pesto Turn Dark — and How to Prevent It?
When exposed to air, basil oxidises quickly and loses its color. To keep that bright green:
- add a little lemon juice,
- store under a layer of olive oil,
- don’t overheat the sauce in the blender — use short pulse bursts.

This sauce is incredibly versatile: great with pasta, in salads, as a bread spread or a dressing for roasted vegetables.
What to Eat Pesto With?
Pesto is an extraordinarily versatile sauce. Here are a few ideas:
- Pasta with pesto — the classic choice (spaghetti, tagliatelle, linguine).
- Soups — a spoonful of pesto stirred into minestrone or vegetable cream soups.
- Meat and fish — as a marinade or finishing sauce.
- Starters — bruschetta, toast spreads, crackers.
- Vegetables — as a dressing for salads, roasted vegetables or potatoes.
- Pizza — instead of tomato sauce, or as an extra topping.
How to Store Pesto?
- In the fridge — 3–4 days, covered with a layer of olive oil.
- In the freezer — up to 3–4 months in containers or ice-cube trays.
- Not recommended — leaving it at room temperature or storing longer than 5 days, as the cheese and nuts spoil quickly.

- Use a marble mortar for the most authentic flavor.
- In a blender, use short pulse bursts so the ingredients don’t heat up.
- Add a few drops of lemon to preserve the vibrant color.
- Experiment with different greens and nuts — you will discover entirely new flavors.
