Sweet Potato Gnocchi in Sage Butter

Chef's Overview

Dear Chefs, homemade gnocchi has a reputation as a project for patient people with floury forearms, and sweet potato gnocchi quietly breaks that rule. Roasting the potatoes whole drives off moisture, which means the dough needs very little flour and the finished dumplings come out tender instead of gummy. A scoop of ricotta and a handful of Parmesan add richness and structure, while the sweet potato brings a natural, caramelized sweetness that suits fall perfectly. Everything lands in a skillet of browned sage butter, where the edges of each gnocco turn golden and a little crisp. Give yourself about ninety minutes, most of it hands-off, and you walk away with a dinner that tastes like a restaurant order.

The Night Our Gnocchi Turned Into Library Paste

Our first attempt at gnocchi, years ago, ended with a pot of boiled glue. We boiled the sweet potatoes in water, mashed them while they were still steaming, then kept adding flour until the dough stopped sticking to our hands, which is exactly how you build a dumpling that bounces off a fork. It was edible in the way that wallpaper paste is technically edible, and the dog was the only taster who finished a bowl.

What fixed it was a change in thinking about water rather than flour. Roasting the potatoes whole in their skins concentrates the flavor and dries the flesh, so you need just enough flour to hold things together, and every extra spoonful is a step toward a heavier dumpling. If you are building a fall menu around squash and sweet potato, our Roasted Delicata Squash With Hot Honey and Feta makes a bright, tangy side that plays nicely against this buttery bowl. Sage deserves the second half of the title, because it behaves differently in butter than it does in a stuffing. The leaves crisp up in about a minute, turn glassy and savory, and perfume the whole pan with a flavor that sits halfway between pine and brown butter. Cooks who love our Burrata Pasta with Basil and Roasted Tomatoes tend to find that this dish scratches the same itch on a cooler night, and if you still have zucchini hanging around from summer, our Lemon-Basil Zucchini Ribbon Pasta for When the Garden Won't Quit is the lighter cousin.

Ingredients You'll Need

Gnocchi is a short ingredient list where each item has a job, so it pays to buy well. Pick sweet potatoes of similar size so they roast at the same pace, drain the ricotta in a fine strainer for at least 15 minutes, and use whole-milk ricotta because the low-fat versions leak water into the dough. Fresh sage is non-negotiable here, since dried sage tastes dusty and will not crisp in butter.

For the Gnocchi

• 2 pounds sweet potatoes (about 2 large)
• 1 1/4 cups all-purpose flour, plus more for dusting
• 1/2 cup whole-milk ricotta, well drained
• 1/4 cup finely grated Parmesan
• 1 egg yolk
• 1 teaspoon kosher salt
• 1/4 teaspoon freshly grated nutmeg

For the Sage Butter

• 6 tablespoons unsalted butter
• 12 fresh sage leaves
• 1 small shallot, minced
• 1 tablespoon lemon juice
• Flaky sea salt and black pepper, to taste
• Grated Parmesan and toasted walnuts, for finishing

Step 1: Roast the Sweet Potatoes Whole

Heat the oven to 400°F, scrub the sweet potatoes, and prick each one several times with a fork. Set them on a parchment-lined sheet pan and roast for 45 to 55 minutes, until the skins wrinkle, sugary juices leak out, and a paring knife slides in with no resistance. Roasting instead of boiling is the single choice that separates light gnocchi from heavy gnocchi, because the oven removes water while boiling adds it. Let the potatoes sit out for about 15 minutes, until you can handle them without yelping.

Step 2: Rice and Dry the Sweet Potato

Halve each potato lengthwise, and a sharp Opal 60 Damascus Santoku Knife, built from VG-10 Damascus steel with 67 layers and a 60 HRC edge, makes that cut clean through the sticky skin. Scoop the flesh into a ricer or pass it through a fine-mesh sieve with a spatula, then spread it over a clean sheet pan in a thin layer. Leave it for 10 minutes so the steam escapes, which is the quiet trick that lets you use less flour. You want about two cups of fluffy, cool puree before moving on.

Step 3: Mix the Gnocchi Dough

Scrape the puree into a large bowl and add the ricotta, Parmesan, egg yolk, salt, and nutmeg, stirring until smooth. Sprinkle in the flour a third at a time and fold with a bench scraper or spatula just until a soft, slightly tacky dough forms. Resist the urge to knead, because every extra turn develops gluten and turns the dumplings chewy. If the dough clings to your fingers like frosting, dust in another tablespoon of flour, but stop the moment it holds its shape.

Step 4: Roll and Cut the Gnocchi

Turn the dough out onto a floured counter, divide it into four pieces, and roll each into a rope about three-quarters of an inch thick. Cut the ropes into pillows roughly three-quarters of an inch long using the Lapis 59 Damascus Chef Knife, which pairs AUS-10 Damascus steel at 59 HRC with a resin and wood handle. A clean downward cut matters more than speed, because sawing back and forth smears the cut faces and makes the gnocchi stick to each other. Dust the pillows lightly with flour and spread them on a floured sheet pan in a single layer while you prepare the rest.

Step 5: Boil the Gnocchi in Salted Water

Bring a large pot of generously salted water to a gentle boil and cook the gnocchi in two batches. They sink at first, then bob to the surface after about 2 minutes, and that float is your cue to give them another 30 seconds before lifting them out with a spider or slotted spoon. Crowding the pot drops the temperature and turns the dumplings mushy, which is why two batches beat one. Move the finished gnocchi to a lightly oiled plate and keep going.

Step 6: Brown the Sage Butter

Set a large skillet over medium heat and melt the butter, swirling until it foams, then settles, and starts to smell nutty. Add the sage leaves and minced shallot, and cook for 3 to 4 minutes until the leaves turn crisp and the butter shows golden-brown flecks on the bottom of the pan. Pull the skillet off the heat for a moment and stir in the lemon juice, which stops the browning and balances the sweetness of the potato. Work quickly, because brown butter slides to burnt in under thirty seconds.

Step 7: Sear the Gnocchi and Serve

Return the skillet to medium-high heat, add the boiled gnocchi in a single layer, and let them sit undisturbed for 2 minutes until the bottoms turn golden and crisp. Toss gently for another minute, season with flaky salt and pepper, and divide among warm bowls. Finish with grated Parmesan and toasted walnuts, and spoon any extra sage butter over the top. Eat while the edges are still crackling, since that contrast is half the reason to make gnocchi at all.

What Gnocchi Teaches You About Patience and Water

Once you understand that gnocchi is a moisture problem rather than a flour problem, the dish stops being scary. Dry the potatoes, go easy on the flour, and treat the dough like a sleeping cat, and you get dumplings with a delicate, pillowy bite that no packaged version can match. The same lesson applies all over the kitchen, from fluffy pancakes to tender biscuits, where the cook who does less usually wins. Make a double batch on a quiet Sunday, freeze the cut gnocchi on a sheet pan until solid, then bag them for a weeknight dinner that cooks straight from the freezer in about four minutes. That tray of tiny pillows is the best head start a busy cook can give a future self. Your Tuesday evening will thank you.
