Yield: serves 8
For the Gnocchi
- Olive oil, for greasing
- 1 1⁄2 lb. Russet potatoes (about 2 large)
- 1 1⁄2 lb. sweet potatoes (about 2 large)
- 2 tsp. kosher salt, plus more to taste
- 1 cup brown rice flour, plus more for dusting
- 1⁄2 cup sweet potato starch
- 1⁄2 tsp. freshly grated nutmeg
- 1 egg
For the Sauce
- 2 cups heavy cream
- 4 oz. Gorgonzola Dolce, crumbled (about ¾ cup), plus more for garnish
- 1⁄3 cup finely grated Parmigiano-Reggiano
- Freshly grated nutmeg, to taste, plus more for garnish
- Kosher salt, to taste
- 1⁄2 cup lightly toasted walnut halves, coarsely chopped, for garnish
- Make the gnocchi: Heat oven to 400°F. Lightly oil potatoes, prick several times with a fork, and sprinkle with salt. Place on a baking sheet and bake until tender, about 1 hour. Let potatoes cool slightly, peel, and rice into a large bowl. Stir in 2 tsp. salt, the rice flour, starch, nutmeg, and egg until a soft dough forms. Transfer dough to a lightly floured surface; knead briefly until smooth. Quarter dough and cover loosely with plastic wrap. On a lightly floured surface, working with one quarter of dough at a time and using your hands, roll dough into a 40" rope, about ¾" thick. Cut dough crosswise into 1” pieces. Using a gnocchi board or the tines of a fork, roll gnocchi over textured surface to create ridges in the dough. Transfer gnocchi to a flour–dusted, parchment paper–lined baking sheet; cover loosely with a damp towel until ready to cook.
- Make the sauce: Combine cream and cheeses in a 12” skillet over medium; bring to a simmer and cook, stirring occasionally, until sauce is slightly thickened, 8-10 minutes. Season with nutmeg and salt; keep warm. Meanwhile, bring a large pot of salted water to a simmer. Add gnocchi in 2 batches and cook until gnocchi float to surface, 3-4 minutes. Remove gnocchi with a slotted spoon and transfer to pan with sauce; toss to coat. Divide between plates; Garnish with gorgonzola, nutmeg, and walnuts.
