Don’t throw away those celery leaves—they’re packed with punchy celery taste and can be used in place of many savoury herbs in cooking. In this pesto recipe, celery leaves are blended with parsley and then tossed with simple sweet potato gnocchi for a surprisingly sophisticated dinner.
Per serving:
For gnocchi, line large baking sheet with parchment paper. In large bowl, combine sweet potato, ricotta, salt, and nutmeg. Stir in flour using wooden spoon. Using your hands, knead until a dough forms. Cut dough into 4 equal slices and roll into logs; cut logs into 1/2 in (1.25 cm) pieces and indent with your finger. Transfer to prepared baking sheet.
For pesto, pulse garlic and lemon zest in food processor until finely minced. Add celery leaves, parsley, hemp hearts, lemon juice, and salt. Pulse until chopped, scrape down sides, and pulse again. With machine running, drizzle in oil; continue to blend until fully incorporated. Transfer to bowl and set aside.
Bring large pot of water to a boil. Boil gnocchi for 3 to 5 minutes, or until they float to the top and are heated through. Drain well, add gnocchi back to pot along with pesto, and toss. Serve immediately with lemon for seasoning.
