Cacio e Pepe Potato Gnocchi


4 large russet potatoes, scrubbed clean
2 1/2 c. all-purpose flour, plus more for surface
2 large eggs
2 tsp. kosher salt
Freshly ground black pepper
4 tbsp. butter
1/2 freshly grated Parmesan, plus more for serving
1/4 c. freshly grated Pecorino


  1. Preheat oven to 400°. Poke potatoes all over with a fork and place directly on oven racks. Bake until easily pierced with a knife, about 1 hour. Let cool slightly. 
  2. When potatoes are cool enough to handle, cut in half and scoop out insides. Discard skins. Run potatoes through a ricer or mash well with a fork. 
  3. In a large bowl, combine riced potatoes, flour, eggs, salt, and a little pepper until a dough forms. 
  4. Turn dough onto a lightly floured surface and knead until smooth, about 3 minutes.  
  5. Divide dough into 4 pieces. Using your hands, roll each piece into a long rope, about ¾” in diameter. Cut ropes into 1” pieces. Place pieces on a lightly floured baking sheet. If dough is too soft to work with this at this point, place in freezer for 10 minutes to chill. 
  6. On the back side of a fork, roll each piece along the tines to create ridges and place back on baking sheet. 
  7. In a large pot of boiling salted water, cook gnocchi until it floats to the top, about 2 minutes. 
  8. Meanwhile, in a large skillet over medium heat, melt butter. Using a slotted spoon, add cooked gnocchi into melted butter. Season with several cranks of black pepper. Add Parmesan and Pecorino and toss until melted and pepper is fragrant, about 2 minutes. 
  9. Serve warm with more Parmesan.
