This whole lemon pesto, inspired by lemon relishes and creamy white pestos, is a very good reminder that you can make a lively, vibrant pesto with what you already have around — no fresh herbs necessary. It’s savory, nutty, acidic, salty, and a little bit spicy, and will instantly improve everything you’re cooking this summer.
The name comes from the fact that there’s no zesting or juicing involved. Instead, the whole lemon (yes, all of it!) is chopped and seeded and tossed into the bowl of a food processor. When enjoyed this way — juicy and pebbly, the skin and pith chopped fine — it’s enough to give you a jolt without sending you reeling.
The bright, fragrant lemon is combined with buttery walnuts toasted all the way to the edge, and the slow, sweet heat of garlic and chile. These spiky elements are smoothed out with a tiny bit of sugar, grated Pecorino Romano (I like to do this in the food processor — just load in the cheese and pulse until crumbly), and olive oil. The result is a thick, slightly chunky sauce ready to be dispatched anywhere punchiness is called for.
A Versatile Pesto to Use All Summer Long
Some say leopard print is a neutral, and the same principle applies here: You might not expect a zingy, assertive, big-in-every-direction pesto to be so versatile, but it is! Spread it onto a sandwich; melt it over a whole grilled fish; massage it into ribboned kale for an instant salad; or toss it with cooked grains or pasta (thin the pesto with a little pasta water to make the pesto silky and saucy), or roasted vegetables, or boiled new potatoes.
This pesto can stand up to similarly big flavors like grainy, toasty, toothsome whole-wheat pasta; punchy broccoli rabe or asparagus; or anything a little bit charred, like bread, vegetables, chicken, or fish.

Nutritional Info
Ingredients
- 1/2 cup
walnuts (2 ounces)
- 1
medium lemon, preferably organic
- 1/4 cup
finely-grated Pecorino Romano cheese (about 1/2 ounce)
- 1 small clove
garlic
- 1/2 teaspoon
granulated sugar
- 1/4 teaspoon
kosher salt, plus more as needed
- Pinch
red pepper flakes
- 1/4 cup
extra-virgin olive oil
Instructions
Arrange a rack in the middle of the oven and heat the oven to 350°F. Place 1/2 cup walnuts on a baking sheet and toast in the oven until deeply golden and fragrant, about 8 minutes, shaking the pan halfway through. Meanwhile, cut 1 medium lemon into quarters. Reserve 1 piece for another use. Use your fingers to remove the seeds from the remaining 3 pieces as best you can. Transfer to a food processor fitted with the blade attachment and pulse until finely chopped but not puréed.
When the walnuts are ready, set aside to cool slightly. Transfer to the food processor and add 1/4 cup grated Pecorino Romano cheese, 1 small garlic clove, 1/2 teaspoon granulated sugar, 1/4 teaspoon kosher salt, and a pinch red pepper flakes. Pulse a few times until the walnuts are finely chopped but not pasty.
While pulsing, slowly pour 1/4 cup extra-virgin olive oil through the feed tube and pulse to combine; over-processing will make the olive oil bitter, so use a light hand here. You want the olive oil to be just incorporated and the pesto to still have some texture. Taste and season with more salt as needed.
Recipe Notes
Making by hand: If you don’t have a food processor, you can still make this pesto — just embrace a slightly chunkier texture: Finely chop the walnuts, garlic, and lemon, then stir in the remaining ingredients.
Make ahead: The pesto can be made up to 1 week ahead and refrigerated in an airtight container.
