Ingredients:
- 2 pounds (900g) russet potatoes, unpeeled
- 1 teaspoon (5g) salt, plus more for boiling water
- 1/2 teaspoon (2.5g) freshly ground black pepper
- 1 large egg, lightly beaten
- 1 cup (120g) all-purpose flour, plus more for dusting
- 1/2 cup (113g) unsalted butter
- 1/4 cup (loosely packed) fresh sage leaves
- 1/2 cup (50g) walnuts, roughly chopped
- 1/4 cup (30g) grated Parmesan cheese, plus more for serving (optional)
- Salt and freshly ground black pepper to taste
Instructions:
- Boil potatoes until fork-tender. Cool slightly.
- Pass potatoes through a ricer (or food mill) while still warm. This is key for avoiding gummy gnocchi.
- Gently combine riced potatoes, salt, pepper, and egg. Gradually add flour until a soft, slightly sticky dough forms. Be careful not to overwork!
- Roll dough into ropes and cut into 1-inch pieces. Optionally, roll each piece over a gnocchi board or fork to create ridges.
- Boil gnocchi in salted water until they float to the surface (about 2-3 minutes).
- While the gnocchi cooks, toast the chopped walnuts in a dry skillet until fragrant and lightly browned.
- Melt butter in a skillet over medium heat. Cook until the butter turns brown and smells nutty, about 3-5 minutes. Add sage leaves and cook until fragrant.
- Gently toss cooked gnocchi with brown butter sauce, toasted walnuts, and Parmesan cheese. Serve immediately, garnished with extra Parmesan (if desired).
