Side Dishes
This sweet potato gnocchi recipe transforms humble ingredients into pillowy, golden dumplings that pair perfectly with rich sage butter.
The secret lies in the dough—mashed sweet potatoes and flour create a tender yet sturdy texture that boils up light and fluffy, while the sage butter adds an aromatic, savory depth that elevates every bite.
What makes this dish special is how simple yet impressive it feels, turning a weeknight into a restaurant-worthy experience without requiring advanced skills.
The process is straightforward: boil the sweet potatoes until tender, mash them with flour and a pinch of salt, then roll and cut the dough into classic gnocchi shapes. A quick boil in salted water ensures they float and develop that signature ridged, pillowy surface.
Meanwhile, the sage butter—made with browned butter, fresh sage, and a touch of garlic—infuses the dish with a fragrant, herby richness that melts into the gnocchi, creating a sauce that’s both elegant and comforting.
What you’ll end up with is a dish that’s visually stunning—golden, irregular dumplings piled high on a plate, drizzled with fragrant sage butter, and garnished with crispy sage leaves or a sprinkle of parmesan.

Ingredients for sweet potato gnocchi recipe sage butter
Sweet potatoes, flour, and butter transform into restaurant-worthy gnocchi with aromatic sage butter sauce.
| Ingredient | Amount | Notes |
|---|---|---|
| Large Sweet Potatoes 🍠 | 2 whole | Organic preferred, peeled and boiled |
| All-Purpose Flour 🌾 | 2 cups | Plus 2 tbsp for dusting |
| Unsalted Butter 🧈 | ½ lb | Cold, cut into pieces |
| Fresh Sage Leaves 🌿 | ½ cup | Packed, stems removed |
| Garlic Cloves 🧄 | 3 cloves | Minced, fresh preferred |
| Sea Salt 🧂 | 1 ½ tsp | Fine grain preferred |
| Freshly Ground Black Pepper 🌶️ | ½ tsp | Freshly cracked |
| Vegetable Oil 🫒 | 2 tbsp | For boiling water |
| Parmesan Cheese 🧀 | ¼ cup | Freshly grated from block |
| Large Egg 🥚 | 1 whole | Optional for extra binding |
| Semolina Flour 🌾 | ¼ cup | For rolling surface |
Sweet potatoes are the foundation—organic ones have richer flavor, but any firm variety works. Trader Joe's often carries the best pre-peeled ones, but regular sweet potatoes peel easily with a vegetable peeler. Boil them until fork-tender (about 15 minutes), then mash while still warm for a smoother dough. The flour needs to be all-purpose (not cake flour)—it gives the gnocchi that signature chew. For the butter, Plugrá or Land O'Lakes are reliable choices, but any unsalted butter works if it's cold and cut into even pieces. Fresh sage is non-negotiable here; dried won't give that same aromatic punch.
No semolina? All-purpose flour works in a pinch, though the gnocchi might not get that signature texture. Running short on sage? Thyme at half the amount adds depth, though it won't be identical. The egg is optional but helps bind the dough if your sweet potatoes are extra wet. For the garlic, roasted garlic adds sweetness, but fresh minced gives that sharp bite. If you're making this ahead, store the dough (unrolled) between parchment paper in the fridge for up to 24 hours. The butter sauce can be made separately and reheated gently with the gnocchi.
Gnocchi dough keeps best in an airtight container in the fridge for 2 days or frozen for 3 months. The sage butter sauce should be made fresh (it reheats beautifully though). For extra crispiness, fry the sage leaves in the butter until golden before adding to the sauce. This dish reheats wonderfully—just warm in a skillet with a splash of water to prevent drying. Leftovers freeze perfectly for up to 2 months; thaw in the fridge overnight before reheating.

Step-by-step instructions for sweet potato gnocchi with sage butter
Here's how to craft tender sweet potato gnocchi with a fragrant sage butter sauce—every step matters.
Cook and Mash the Sweet Potatoes
Place the 2 whole large sweet potatoes in a pot and cover with cold water by 2 inches. Add the 2 tablespoons vegetable oil to prevent skin from sticking. Bring to a boil over high heat, then reduce to medium-high and cook for 20-25 minutes until a knife slides in easily. Drain and let cool for 5 minutes before peeling.
Transfer the peeled potatoes to a clean bowl and mash until completely smooth—no lumps should remain. The texture should be like mashed potatoes but slightly drier. Let cool to room temperature while you prepare the dough. This cooling step prevents the dough from becoming too sticky when mixed with flour.
Make the Gnocchi Dough
On a clean surface dusted with the 2 tablespoons extra all-purpose flour (from the ingredients list), mound the mashed sweet potatoes. Create a well in the center and add the 2 cups all-purpose flour and the 1 whole large egg (if using). Gently fold the ingredients together with a fork or rubber spatula until just combined.
Knead lightly for 2-3 minutes until the dough holds together but remains slightly sticky. If it feels too dry, add 1 teaspoon water at a time. Shape into a log about 2 inches thick and wrap tightly in plastic wrap. Rest for 30 minutes at room temperature—this relaxes the gluten for easier cutting.
Roll and Cut the Gnocchi
Cut the rested dough log into ½-inch thick slices. Dust a clean surface with the ¼ cup semolina flour and roll each slice gently over a wooden gnocchi board or the back of a fork to create ridges. These ridges help the dumplings cling to the sauce later. Keep uncooked gnocchi dusted with semolina flour to prevent sticking.
Cook immediately or freeze on a parchment-lined tray for 15 minutes before transferring to a bag. For fresh cooking, drop the gnocchi into boiling salted water in batches. They're done when they float to the surface (2-3 minutes). Remove with a slotted spoon and drain well.
Prepare the Sage Butter Sauce
In a large skillet, melt the ½ pound unsalted butter over medium-low heat. Add the 3 minced garlic cloves and ½ cup packed fresh sage leaves, cooking for 2-3 minutes until the sage leaves are crispy and the butter turns golden. Remove from heat and stir in the ¼ cup freshly grated parmesan cheese and ½ teaspoon freshly ground black pepper.
Return the skillet to low heat and add the cooked gnocchi, tossing gently to coat evenly. Season with the 1½ teaspoons sea salt and serve immediately with additional parmesan cheese if desired. The sauce should be rich and fragrant with crispy sage leaves throughout.
Pro Tips For Making Sweet Potato Gnocchi Recipe Sage Butter
- BOIL UNTIL FLAKY: Sweet potatoes should fall apart like a wet paper towel when ready—not mushy, not rubbery. I learned this the hard way when my first batch turned into glue; test with a fork every 15 minutes after 20 minutes of boiling.
- STEAM THE SAGE: Toss fresh sage leaves into the butter after it melts but before it foams—just a few seconds of steaming softens the leaves and releases their aroma without burning. (Yes, even if you're impatient like me, resist the urge to skip this.)
- REST THE DOUGH: Let the sweet potato-flour mix sit covered for 20 minutes after mixing. This isn’t just "waiting"—it lets the starches settle so your gnocchi holds shape when boiling. I used to skip it, and my dumplings always split like overripe fruit.
- SALT THE PASTA WATER: Use 1 tablespoon salt per 4 cups water—more if you’re using unsalted butter later. The gnocchi soaks up flavor like a sponge, and underseasoned water means bland, sad dumplings. (Your future self will thank you.)
Dietary considerations for this dish
Gluten-Free Adaptations
For a gluten-free version, replace the 2 cups all-purpose flour with a 1:1 gluten-free blend like Bob's Red Mill 1-to-1. Add 1 extra tablespoon of cornstarch to help bind the dough, as gluten-free flours can be stickier.
I've tested this substitution and found the gnocchi hold together beautifully when rested properly. 🌾
Vegan Substitutions
Swap the butter for vegan butter (like Miyoko's) and use nutritional yeast instead of parmesan for a cheesy flavor. For extra richness, add 2 tablespoons olive oil to the sage butter sauce.
The gnocchi will still be tender, though slightly less rich without dairy. I recommend serving with a drizzle of chili oil for added depth.
Low-Carb Options
Reduce the flour to just 1 cup and increase the sweet potato to 3 medium potatoes for a lower-carb version. The texture will be slightly denser but still pillowy.
Pair with a side of roasted Brussels sprouts to keep the meal balanced. This approach cuts carbs by about 30% while maintaining the dish's comforting qualities.
Allergen-Friendly Notes
This recipe is naturally free of dairy if you skip the parmesan and butter (use vegan alternatives). For egg-free gnocchi, omit the egg entirely—the sweet potato dough binds well without it.
Always check your flour for cross-contamination if allergies are a concern. I keep a dedicated King Arthur gluten-free flour on hand for safe prep.
Nut-Free Considerations
No nuts are used in this recipe, making it safe for nut allergies. However, if you're using pre-made gluten-free flour blends, verify they're processed in nut-free facilities. The sage butter sauce is inherently nut-free, but always double-check labels on store-bought ingredients like butter or parmesan for potential cross-contamination warnings.

Frequently asked questions
Can I use regular potatoes instead of sweet potatoes?
While you can substitute regular potatoes, the flavor and texture will be different. Sweet potatoes add natural sweetness and a vibrant orange hue that pairs beautifully with sage butter. For a closer match, use orange-fleshed potatoes (like Yukon Gold) and reduce the flour by 1 tablespoon since they're slightly drier. The gnocchi will be less sweet but still delicious!
Why did my gnocchi turn out dense instead of pillowy? Dense gnocchi usually happen when the dough is overworked or the sweet potatoes weren't mashed smooth enough.
How do I store leftover gnocchi?
Cooked gnocchi keep well in the fridge for 3-4 days in an airtight container. For longer storage, freeze them on a tray first (to prevent sticking), then transfer to a bag for up to 3 months. To reheat, drop frozen gnocchi directly into boiling water for 1-2 minutes, then toss with fresh sage butter. Never microwave—it makes them rubbery!
Can I make the sage butter sauce ahead of time?
Yes! Make the sauce up to 2 days ahead and store it in the fridge. Reheat gently over low heat until melted, then add the gnocchi. For extra flavor, add 1 extra sage leaf while reheating. The butter will solidify when cold, so reheat just before serving for the best texture. This is perfect for meal prep!
What's the best way to serve this dish?
These gnocchi shine as a main dish with a simple arugula salad or roasted Brussels sprouts. For extra elegance, garnish with crispy fried sage leaves and a sprinkle of pecorino romano. Pair with a crisp Pinot Grigio or a dry Chardonnay. The sage butter sauce is rich enough to stand alone, but adding a squeeze of lemon brightens the flavors beautifully!
