1 lb. russet potatoes, unpeeled
Kosher salt, to taste
4 oz. spinach
1 1⁄4 cups semolina flour, sifted, plus more
2 eggs, beaten
18 tbsp. unsalted butter
16 leaves fresh sage, minced
1⁄4 tsp. freshly grated nutmeg
Freshly ground pepper, to taste
4 tbsp. olive oil
3 tbsp. finely grated Parmesan
Put potatoes into a 4-qt. pot of salted water; boil. Reduce heat to medium-low; simmer until potatoes are tender, 25 minutes. Drain; let cool. Peel potatoes; pass through medium plate of a food mill into a bowl.
Meanwhile, heat a 12″ skillet over medium-high heat. Add spinach and 1 tbsp. of water; cook until wilted. Press on spinach in a sieve to extract liquid. Finely chop spinach; stir together with potatoes and semolina and form a well in the center.
Add eggs and salt and, using a fork, beat eggs into potato mixture.
Transfer dough to a work surface dusted with semolina; knead to combine.
Divide the dough into 6 portions. Roll each portion into a 1⁄2″-thick rope. Cut ropes into 1⁄2″-wide pieces; transfer to a semolina-dusted sheet tray.
Melt 10 tbsp. butter in a 10″ skillet over medium heat; cook, swirling, until butter browns, about 6 minutes.
Add sage and nutmeg; season with salt and pepper.
Remove from heat; set aside.
Working in 4 batches, add 2 tbsp. butter and 1 tbsp. oil to a 12″ skillet over medium-high heat. Add dough pieces and cook, flipping once, until golden brown, 3–4 minutes.
Transfer to a baking sheet.
Wipe out the skillet and repeat with remaining butter, oil, and dough pieces.
Toss dumplings and brown butter sauce in the skillet until hot.
Serve sprinkled with Parmesan.
Here is the photo of my version. Served with a lovely red wine!
Would definitely make for friends.
I made the gnocchi about three in the afternoon, and just put them all together right before dinner.
