Phase 1: Preparing the Sweet Potatoes

This initial step is the most critical for controlling the moisture content of your dough.

1. Preheat and Prep: Preheat your oven to 400°F (200°C). Thoroughly wash and scrub the sweet potatoes to remove any dirt. Pierce each potato several times with a fork. This allows steam to escape during baking, preventing them from bursting and helping them to dry out.
2. Bake the Potatoes: Place the potatoes directly on the oven rack or on a baking sheet lined with parchment paper. Bake for 50-60 minutes, or until they are completely tender and easily pierced with a knife. The skins should look slightly wrinkly.
3. Cool and Scoop: Remove the potatoes from the oven and let them cool just enough so you can handle them, about 10-15 minutes. Once cool enough, slice them in half lengthwise. The flesh should be vibrant orange and steaming. Use a spoon to scoop the soft flesh out of the skins and into a large bowl. Discard the skins.

Phase 2: Creating the Light and Airy Dough

The goal here is to combine the ingredients gently and quickly to avoid overworking the dough.

1. Rice the Potatoes: For the absolute best texture, pass the warm sweet potato flesh through a potato ricer or a food mill. This breaks up the potato into fine, fluffy strands without developing starches, which can make the dough gluey. If you don’t have a ricer, you can mash them thoroughly with a potato masher, ensuring there are absolutely no lumps.
2. Spread and Cool: Spread the riced sweet potato out on a large baking sheet or a clean work surface. This allows excess steam to evaporate and helps the potato cool down further. Let it sit for about 10 minutes. A drier, cooler potato base requires less flour, which is the key to light gnocchi.
3. Combine Ingredients: Gather the cooled potato into a mound on your work surface. Create a well in the center. Add the drained ricotta, beaten egg, fine sea salt, and freshly grated nutmeg into the well.
4. Incorporate the Flour: Sprinkle 1 cup of the all-purpose flour evenly over the top of the mound. Using a bench scraper or your hands, gently begin to fold the ingredients together. Work quickly and delicately, folding and pressing just until a shaggy, slightly sticky dough begins to form.
5. Knead Gently: If the dough is overly sticky, add the remaining ½ cup of flour, a little at a time, until the dough is soft, pliable, and just slightly tacky. Knead for no more than 30-60 seconds. The less you work the dough, the more tender your gnocchi will be. The final dough should feel like a soft pillow.

Phase 3: Shaping the Gnocchi Dumplings

This is the fun, hands-on part. Don’t worry about making them all look identical; rustic charm is part of the appeal.

1. Divide the Dough: Lightly flour your work surface. Divide the dough into 4 equal portions.
2. Roll into Ropes: Working with one portion at a time (keep the others covered with a clean kitchen towel to prevent them from drying out), use your palms to gently roll the dough into a long rope, about ¾-inch in diameter.
3. Cut the Gnocchi: Use a bench scraper or a sharp knife to cut the rope into ¾-inch pieces. These are your individual gnocchi.
4. Create the Ridges (Optional but Recommended): The classic ridges on gnocchi aren’t just for looks; they create little pockets that are perfect for catching and holding onto sauce. To create them, you can use a gnocchi board or the back of a fork. Take one piece of gnocchi and, with your thumb, gently push and roll it down the tines of the fork. The gnocchi will curl slightly and be imprinted with ridges on one side and have a small dimple from your thumb on the other.
5. Arrange for Cooking: As you shape each gnocchi, place it on a baking sheet generously dusted with flour or semolina flour. Ensure they are in a single layer and not touching, which will prevent them from sticking together.

Phase 4: Cooking the Gnocchi

You can cook the gnocchi right away, or refrigerate or freeze them for later (see FAQ for details).

1. Boil the Water: Bring a large pot of heavily salted water to a rolling boil. The water should taste like the sea.
2. Cook in Batches: Carefully drop the gnocchi into the boiling water, working in 2-3 batches. Do not overcrowd the pot, as this will lower the water temperature and can cause the gnocchi to cook unevenly or clump together.
3. Watch for the Float: The gnocchi will sink to the bottom initially. After 2-3 minutes, they will begin to float to the surface. This is the sign that they are cooked through. Let them bob on the surface for another 30 seconds to ensure the center is cooked.
4. Remove and Drain: Use a slotted spoon or spider strainer to gently lift the cooked gnocchi out of the water and transfer them directly to your prepared sauce or a bowl.
5. The Pro-Move: Pan-Sear for Texture! For an incredible texture contrast, heat a tablespoon of butter or olive oil in a large skillet over medium-high heat. Add the boiled and drained gnocchi in a single layer. Cook for 1-2 minutes per side, until they are golden brown and slightly crispy. This gives them a wonderfully crisp exterior while maintaining their soft, pillowy interior.
