Italian Ligurian Pesto with Green Lentil Cream
A modern interpretation of Liguria's iconic pesto, blended with roasted green lentils for unexpected depth and a velvety texture. Fresh basil, toasted pine nuts, aged Parmigiano-Reggiano, and good olive oil create a herbaceous base that pairs beautifully with the subtle nuttiness of the lentils. Serve as a dip with crudités, crackers, or toasted bread, or thin it with pasta water to coat fresh pasta.

Steps
Before you start
- Bring a small pot of salted water to a boil if cooking lentils from scratch (see substitutions for using canned).
- Measure all ingredients before you begin blending—this is a quick final step once everything is ready.
- Use fresh basil at room temperature; cold leaves make the pesto bitter and gray.
Cook the lentils
- Add the rinsed green lentils to a small pot of salted boiling water (about 2 cups / 480 ml water).
- Reduce heat to medium-low and simmer gently for 20–25 minutes, until the lentils are completely tender but still hold their shape—they should not be mushy or falling apart.
- Drain in a colander and spread on a plate to cool slightly, about 5 minutes.

Ready when: Lentils are completely soft but still intact, not mushy
Tip: Do not over-cook the lentils or the pesto will taste dull and muddy. They should have a slight bite.
Toast the pine nuts
- While the lentils cook, place the pine nuts in a small dry skillet over medium heat.
- Toast for 2–3 minutes, shaking the pan frequently, until they smell fragrant and turn a pale golden color.
- Transfer immediately to a plate to cool—they will continue to darken slightly off heat.

Ready when: Nuts are light golden and fragrant
Tip: Watch constantly; pine nuts burn quickly and taste bitter if scorched. Spread them out to cool immediately.
Assemble and blend
- In a food processor, combine the cooled lentils, basil leaves, toasted pine nuts, minced garlic, grated Parmigiano-Reggiano, and lemon juice.
- Pulse several times until roughly combined, then drizzle in the olive oil while the machine runs.
- Blend until you reach your desired consistency—a rustic, chunky pesto or a smoother cream, depending on preference.
- Season to taste with kosher salt and freshly ground black pepper.

Ready when: Mixture is well-blended with small flecks of basil and texture you prefer
Tip: Pulse gently at first to preserve the basil's vibrant color. Over-blending heats and oxidizes the basil, turning it gray and bitter. If the pesto seems too thick, drizzle in a tablespoon of cold water at a time.
Rest and serve
- Transfer the pesto to a serving bowl.
- Let it rest at room temperature for 10 minutes to allow the flavors to meld.
- Taste and adjust seasoning one final time before serving.

Tip: This resting period is important for the flavors to come together and balance.
Good to know
Tips
- Fresh, bright basil is crucial—use it the day you buy it if possible. Warm, wilted, or refrigerated basil will taste bitter and dull in the final pesto.
- Toast the pine nuts yourself rather than buying pre-toasted ones. The flavor difference is significant, and they stay fresher longer.
- This pesto is more forgiving than traditional pesto because the lentils add body and buffer the harshness of over-blended basil. Still, restraint wins—pulse, don't purée.
- Serve with crusty bread, crudités (bell peppers, cucumbers, radishes), crackers, or toss with warm pasta using 2–3 tablespoons of pesto per serving. Thin with pasta water or extra olive oil if needed.
Make ahead
Prepare the pesto up to 1 day ahead. Cover tightly and refrigerate. Bring to room temperature and stir well before serving; the flavors brighten when warmed slightly.
Storage & reheating
Store covered in the refrigerator for up to 5 days. For longer storage, freeze in ice cube trays (about 2 tablespoons per cube) for up to 3 months; thaw at room temperature or add frozen cubes directly to hot pasta. The flavor and color are best within the first 48 hours.
Substitutions
- green lentils (French or Puy lentils preferred) → 1 can (15 oz / 425 g) cooked green or brown lentils, drained and rinsed. Skip the cooking step. Canned lentils work well and save 25 minutes, though the flavor will be slightly less earthy. Drain very well before blending.
- pine nuts → walnuts or almonds, lightly toasted and cooled. Walnuts will add a deeper, earthier note; almonds will be more delicate. Use the same amount by weight. Toast first for best flavor.
- fresh basil leaves, lightly packed → fresh spinach (1.5 cups / 45 g) mixed with 0.5 cup (15 g) fresh mint or parsley. The result will be earthier and less aromatic, but still delicious. Adjust lemon juice to 1.5 tablespoons if using mint.
- Parmigiano-Reggiano cheese → Pecorino Romano or Grana Padano cheese. Pecorino will taste saltier and sharper; Grana Padano is milder and slightly sweeter. Use the same amount.
