Why this formula works
Dry leaves and cold oil limit darkening; pulsing the nuts and garlic before the basil prevents overworking the herbs. Parmesan is folded in last so the pesto stays creamy rather than pasty.

Ingredients
- fresh basil leaves, washed and completely dry60 g (2.12 oz)
- Parmigiano Reggiano, finely grated50 g (1.76 oz)
- pine nuts35 g (1.23 oz)
- small garlic clove, germ removed4 g (0.14 oz)
- mild extra-virgin olive oil, chilled110 g (3.9 oz)
- fresh lemon juice8 g (0.28 oz)
- fine sea salt2 g (0.07 oz)
Equipment
- salad spinner and clean towel
- small food processor or mortar
- fine grater
- clean 300 ml jar
Exact method
- 1. Dry the washed basil meticulously; surface water dilutes flavor and shortens keeping quality.
- 2. Toast pine nuts in a dry pan over medium-low heat for 3–4 minutes until pale gold, then cool completely for 5 minutes.
- 3. Pulse cooled nuts, garlic and salt to coarse crumbs. Scrape down before herbs go in.
- 4. Add basil and lemon; pulse in six to eight one-second bursts. Stop while tiny leaf flecks are still visible.
- 5. With the motor pulsing, add 90 g chilled oil in a thin stream. Do not run continuously, which heats and bruises the basil.
- 6. Fold in Parmesan by hand, then adjust texture with the remaining 20 g oil. Taste only now before changing salt.
- 7. Rest 5 minutes, then spoon into a clean jar and cover the surface directly. Use 20–30 g on a pizza after baking or in small protected dots before baking.
How to know it is ready
- Color is vivid green with visible herb flecks.
- It falls slowly from a spoon instead of running like oil.
- Garlic supports basil and does not burn in the finish.
Troubleshooting
- Brown pesto: basil was wet, warm or processed too long.
- Greasy separation: fold in 1–2 teaspoons cold water immediately before serving.
- Bitter finish: use a milder oil and shorter pulses.
- Too salty: add more basil and oil, not lemon alone.
How to adapt the base recipe
- Replace pine nuts with toasted sunflower seeds for a pine-nut-free version.
- For baking, loosen 20 g pesto with 5 g water and place beneath cheese to shield the herbs.
- For pasta, loosen each portion with starchy cooking water rather than extra oil.
Storage and food safety
Because fresh herbs and garlic sit in oil, refrigerate immediately and use within 4 days, or freeze in small portions for up to 3 months. Never store this pesto at room temperature.
