Sweet potato gnocchi makes a tender, comforting meal with roasted sweet potato, a small amount of flour, and a simple piping method. Serve the delicate dumplings with your favorite sauce or pan-crisp them for golden edges.
This is a wonderful dish to make when you want homemade gnocchi without spending time rolling ropes of dough or shaping every piece by hand. Instead, the soft mixture goes into a piping bag and is cut directly over simmering water.
Roasting the sweet potatoes concentrates their natural sweetness while helping prevent the dough from becoming overly wet. Once cooled, the flesh is mixed gently with egg yolk, salt, and just enough flour to hold everything together.
The result is intentionally soft and delicate. You can transfer the cooked gnocchi straight into a warm sauce or sauté them in olive oil for a lightly crisp exterior that contrasts beautifully with the fluffy center.
Sweet Potato Gnocchi Ingredients
Sweet potatoes: Roasting develops their flavor and creates the soft base of the dough. Select potatoes of similar size so they finish cooking at roughly the same time.
All-purpose flour: A modest amount gives the gnocchi enough structure to hold together while boiling. Adding too much can make the finished dumplings heavy.
Egg yolk: Helps bind the dough and gives it a slightly richer texture. It can be omitted when making a vegan version.
Salt: Seasons the sweet potato mixture from within so the gnocchi taste balanced even before sauce is added.
Cooking Steps
STEP 1: Heat your oven to 400°F, or 200°C. Pierce the sweet potatoes several times with a sharp knife, then arrange them on a baking sheet. Using similarly sized potatoes will encourage even roasting.
STEP 2: Bake the sweet potatoes for 45 to 60 minutes, turning them once halfway through. They are ready when a knife slides easily into the center. Remove them promptly once tender because overbaking can make the flesh watery and difficult to work with.
STEP 3: While the potatoes are still warm enough to handle, cut them open lengthwise and scoop out the flesh. Pass it through a potato ricer onto a tray lined with paper towels. Alternatively, mash it thoroughly and spread it into a thin layer. Let it cool completely.
STEP 4: Place the cooled sweet potato in a mixing bowl. Gently stir in the egg yolk, unless you are preparing the vegan option. Add the salt and flour, then use a fork to cut and fold the mixture together until a soft dough forms. Avoid beating or vigorously stirring it.
STEP 5: Transfer the dough to a piping bag or a sturdy resealable bag. Cut an opening about 1.5 centimeters wide. Bring a large pot of generously salted water to a steady boil, then reduce the heat slightly if the water is splashing aggressively.
STEP 6: Hold the piping bag just above the water. Squeeze out a short length of dough and cut off pieces measuring about 2 centimeters with clean kitchen scissors. Let each piece fall directly into the water. Work in small batches so the pot does not become crowded.
STEP 7: Cook the gnocchi until they rise to the surface. Let them continue cooking for about 30 seconds after they float, then remove them carefully with a slotted spoon or spider strainer. Transfer them to a lightly oiled tray while you cook the remaining dough.
STEP 8: Add the boiled gnocchi directly to a warm sauce, or heat a little olive oil in a skillet and sauté them until lightly golden. Turn them gently because their low-flour dough creates an especially soft, fluffy exterior.
Serving Ideas for Sweet Potato Gnocchi
Browned butter and crisp sage are classic partners for the natural sweetness of these dumplings. Let the butter cook until it smells nutty, add fresh sage leaves, and then toss in the gnocchi just long enough to coat them.
A creamy Parmesan sauce also works well when you want a richer dinner. Keep the sauce slightly loose because the gnocchi will absorb some of it as they sit.
For a lighter plate, serve the gnocchi with garlic-infused olive oil and a simple green vegetable. Roasted broccoli, sautéed spinach, or tender green beans add color and balance without covering the sweet potato flavor.
Why must the sweet potato cool completely?
Warm sweet potato can absorb flour differently and may create a sticky, overly soft dough. Cooling also allows excess steam to escape. This helps you use less flour, which is important for preserving the tender texture of the gnocchi.
Can I prepare the dough ahead of time?
Yes. Transfer the finished dough to the piping bag, close the open end securely, and refrigerate it until you are ready to cook. For the most reliable texture, prepare and boil it within one day rather than storing the raw mixture for an extended period.
Can I make these gnocchi without egg?
The egg yolk can be omitted for a vegan preparation. The dough may be slightly more delicate, so pipe smaller pieces and avoid overcrowding the pot. Handle the cooked gnocchi carefully when transferring them from the water.
Why are my cooked gnocchi so soft?
These gnocchi use less flour than many traditional versions, so their exterior remains unusually soft and fluffy. This is expected. If they dissolve completely, however, the sweet potato may have contained excess moisture or the dough may need a small additional amount of flour.
Do I need a potato ricer?
A ricer produces a fine, airy texture without requiring extensive mashing, but it is not essential. A regular potato masher will work. Mash thoroughly, then spread the sweet potato over paper towels in a thin layer to release steam and surface moisture.
Helpful Tips
- Handle the dough as little as possible. Aggressive mixing develops the flour and can turn tender gnocchi into dense dumplings.
- Cook one test piece before piping a full batch. If it breaks apart in the water, gently mix a small spoonful of flour into the remaining dough.
- Keep the kitchen scissors clean and slightly damp while portioning the dough. This helps each piece release neatly into the water.
How to Store and Reheat
Cooked gnocchi can be refrigerated in an airtight container for up to three days. Toss them with a small amount of olive oil before storing so the pieces are less likely to stick together.
For the best reheated texture, warm the gnocchi in a skillet rather than returning them to boiling water. Add a little olive oil or butter and cook over medium heat, turning carefully, until the centers are hot and the surfaces are lightly golden.
You can freeze the cooked gnocchi for up to two months. Arrange them in a single layer on a lined tray and freeze until firm before transferring them to a freezer-safe container. This initial freezing step prevents them from forming one solid clump.
Reheat frozen gnocchi directly in a covered skillet with a spoonful of water and a little oil or butter. Once they have thawed and warmed through, uncover the skillet and let the surfaces crisp. Avoid thawing them at room temperature, where their delicate texture may become sticky.
Sweet Potato Gnocchi
Ingredients
- 5.3 oz all-purpose flour preferably King Arthur all-purpose flour
- 1½ teaspoons salt
- 2.2 lb sweet potatoes selected in similar sizes for even baking
- 1 egg yolk omitted for a vegan preparation
Instructions
- Heat the oven to 400°F (200°C).
- Using a sharp knife, puncture each sweet potato several times around its surface.
- Place the sweet potatoes on a baking sheet and roast for 45 minutes to 1 hour. Turn them over halfway through the baking period. They are ready when a knife passes easily through the center.
- Avoid baking them beyond this point, as excessively cooked sweet potatoes may become watery and overly soft.
- While the baked sweet potatoes remain warm, make a lengthwise opening through the center of each one and remove the flesh. The skins should separate without difficulty.
- Press the sweet potato flesh through a potato ricer directly onto a paper towel-lined tray. This helps maintain a lighter consistency.
- When a potato ricer is unavailable, thoroughly mash the flesh with a potato masher, then distribute it across the paper towels in a thin, level layer.
- Allow the prepared sweet potato to cool completely before mixing the dough.
- Transfer the cooled sweet potato flesh to a mixing bowl.
- Add the egg yolk and stir briefly to incorporate it. Leave out the yolk when preparing the vegan variation.
- Sprinkle in the salt and all-purpose flour.
- Using a fork, make gentle cutting motions back and forth through the mixture until the ingredients form a soft, loosely combined dough. Handle the mixture lightly and avoid vigorous stirring, which can produce dense gnocchi.
- Spoon the finished dough into a piping bag. A resealable plastic bag may also be used; cut an opening approximately 1.5 cm wide from one corner.
- At this stage, the filled bag may be refrigerated when the gnocchi will be boiled later.
- Bring a large pot of generously salted water to a boil.
- Position the opening of the bag slightly above the water. Squeeze out the dough continuously and use sharp scissors to cut it into pieces measuring approximately 2 cm, allowing each portion to fall directly into the boiling water.
- Work in separate batches, piping and cutting the dough for approximately 30 seconds at a time.
- Cook each batch until the gnocchi rise to the surface.
- Once they are floating, continue cooking them for an additional 30 seconds.
- Lift the cooked gnocchi from the water with a slotted spoon or spider strainer, then place them on a tray. Repeat the process with the remaining dough.
- Because the recipe uses only a small quantity of flour, the exterior of the cooked gnocchi may appear exceptionally soft or fluffy. This is the intended texture.
- Add the freshly boiled gnocchi directly to the pasta sauce of your choice.
- For a crisp exterior and deeper flavor, lightly pan-fry the gnocchi in olive oil until evenly golden. They may then be served with browned butter and crisp sage.
