A garlic-free basil pesto with toasted pine nuts and lemon, blended in ten minutes.
Lightly golden pine nuts, a splash of lemon and the aroma of fresh basil: this pesto is all about clean, distinct flavors. It departs from classic Genoese pesto, pounded in a mortar with garlic, raw pine nuts, Parmesan and pecorino, in favor of a blended, garlic-free version with toasted pine nuts and lemon. Allow about 10 minutes to toast the pine nuts and blend everything together. Find this recipe among my keto sauces and dips.
What is this basil pesto?
This pesto is a soft, spreadable green paste built around fresh basil, pine nuts, olive oil and a salty ingredient rich in umami. The ingredients are blended into an even mixture with fine flecks still visible.
Its balance comes from a few carefully measured contrasts: basil brings herbal freshness, olive oil adds body, toasted pine nuts provide a roasted, nutty note, and Parmesan, pecorino or nutritional yeast adds savory depth. Lemon juice cuts through the richness of the oil and adds brightness. Without garlic, the basil and toasted pine nuts stand out more.
A quick, lemony, garlic-free version
Here, a blender replaces the mortar: a small food processor or an immersion blender will do the job. Each choice matters: toasted pine nuts for depth, a single salty ingredient for clean flavors, and nutritional yeast for a vegan variation.
As a spread for pre-dinner drinks and nibbles, this recipe serves four. For pasta or a cold salad, it makes closer to one or two servings, depending on how generously you use it.
The main ingredients
Fresh basil, about 25 g, forms the backbone of the sauce. Choose fragrant leaves, wash them, then dry them very thoroughly, as any remaining water thins the mixture and spoils its texture. The pine nuts, also 25 g, add substance and a nutty flavor. Dry-toast them until lightly golden, then let them cool slightly before blending.
Extra virgin olive oil, 50 ml, binds the ingredients and adds smoothness; reserve some to loosen the paste gradually without drowning it. The juice of half a lemon provides acidity to balance the fat and salt, along with brightness, though it does not guarantee a lasting green color.
For the salty note, just one option is enough. Grated Parmesan, 25 g, adds salt, structure and depth, with an intensity that varies according to its age, so taste before adding salt. The same quantity of pecorino gives a bolder, saltier flavor; for a lactose-free option, check the label, as sheep’s milk does not guarantee the absence of lactose. For a vegan version, replace the cheese with 3 tablespoons of nutritional yeast flakes, not to be confused with baker’s yeast, and a pinch of sea salt.
Technique tips and serving
For the best texture, blend briefly in pulses; a little oil rising to the surface is nothing to worry about: simply stir before serving, and if the mixture seems too thick, add the reserved oil a little at a time. Pine nuts toast quickly: a small, hot pan with no added fat turns them golden and brings out their toasted aroma. Remove them from the heat as soon as they are golden, as burnt flavors would overwhelm the basil.
Serve this pesto on toast, with raw vegetable sticks, in a salad or with well-drained grilled vegetables. It also goes very well with air fryer fish or shrimp. When serving it with pasta, stir it in off the heat, loosening it with a little pasta cooking water. Refrigerate promptly in a clean, airtight container, or freeze in small portions to keep it longer. With these quantities, allow 1 g of net carbs per serving when divided into four appetizer portions, a figure that depends on the cheese or yeast option and the amount of lemon used.
