Ingredients for sweet potato gnocchi recipe sage butter
Sweet potatoes, flour, eggs, and butter come together for pillowy gnocchi with aromatic sage butter.
| Ingredient | Amount | Notes |
|---|---|---|
| Large Sweet Potatoes 🍠 | 2 whole | Peeled, puréed until smooth |
| All-Purpose Flour 🌾 | 2 cups | Plus 2 tbsp for dusting |
| Large Eggs 🥚 | 2 whole | Room temperature preferred |
| Salt 🧂 | 1 tsp | Fine sea salt preferred |
| Unsalted Butter 🧈 | ½ cup | Cold, cubed for sage butter |
| Fresh Sage Leaves 🌿 | ½ cup | Plus extra for garnish |
| Parmesan Cheese 🧀 | ¼ cup | Freshly grated, for finishing |
| Olive Oil 🫒 | 1 tbsp | For dusting gnocchi |
| Garlic Cloves 🧄 | 1 clove | Minced, optional for sage butter |
| Black Pepper 🌶️ | ¼ tsp | Freshly ground |
| Vegetable Oil 🫒 | 4 cups | For boiling gnocchi |
The sweet potatoes are the foundation—orange-fleshed varieties like Jewel or Beauregard work best, with their natural sweetness balancing the earthy sage. Whole Foods or Trader Joe's carry excellent options, or any grocery store's produce section will have them. For the purée, roasting the potatoes first (425°F for 45 minutes) deepens their flavor—skip microwaving, which can make them watery. The dough needs to rest at least 30 minutes before shaping; this step is non-negotiable for preventing breakage during boiling. Diamond Crystal kosher salt is my go-to for seasoning, as its fine grains dissolve evenly.
No fresh sage? Dried sage at half the amount works in a pinch, though the texture won't be as luxurious. For the butter, Plugrá or Land O'Lakes unsalted butter are reliable choices—avoid salted, as it alters the delicate balance. Substituting the Parmesan? Pecorino Romano offers a sharper bite, while nutritional yeast adds umami without dairy. The olive oil for dusting can be swapped for avocado oil if you prefer a neutral flavor. For the garlic in the sage butter, feel free to skip it if you're not a fan—it's purely optional but adds a subtle depth.
Shape the gnocchi immediately after resting the dough to prevent drying. Store unused dough between parchment paper in the fridge for up to 24 hours, or freeze shaped gnocchi on a tray before bagging for 3 months. The sage butter keeps well in an airtight container in the fridge for 5 days, though it's best used fresh. To reheat gnocchi, bake at 400°F for 10-12 minutes with a drizzle of olive oil—this crisps them beautifully. Garnish with extra crispy sage leaves just before serving for that restaurant-quality touch.

Step-by-step instructions for sweet potato gnocchi with sage butter
Follow this method for light, pillowy gnocchi with a rich sage butter sauce every time.
Prepare the Sweet Potato Purée
Preheat your oven to 400°F. Pierce the 2 whole large sweet potatoes with a fork and bake for 45-50 minutes until fork-tender. Let them cool slightly, then peel and transfer to a food processor. Add 1 tsp salt and purée until completely smooth, scraping down the sides as needed. The purée should be silky with no lumps.
This step is crucial for tender gnocchi. If you have any lumps, strain the purée through a fine-mesh sieve. The purée should be cool enough to handle but still warm—around 100°F. If it's too hot, it will cook the flour prematurely when mixed.
Mix and Knead the Dough
Transfer the sweet potato purée to a large mixing bowl and let it cool to room temperature. Add 2 cups all-purpose flour and 2 whole large eggs, then use a wooden spoon to mix until a shaggy dough forms. The dough will be sticky at first, but that's normal.
Turn the dough onto a lightly floured surface and knead gently for 2-3 minutes until smooth and elastic. If the dough is too sticky to handle, wet your hands slightly and continue kneading. The goal is to develop just enough gluten to hold the dough together without making it tough. Avoid overworking it—this can make the gnocchi dense.
Shape the Gnocchi
Divide the dough into 4 equal pieces and roll each piece into a long rope about ½-inch thick. Use a sharp knife or gnocchi board to cut the ropes into 1-inch pieces. For extra pillowy texture, roll each piece gently over a fork or the back of a spoon to create ridges.
Work in batches to prevent drying. Dust your work surface with 2 tbsp flour as needed to keep the dough from sticking. The gnocchi should be soft and slightly tacky—if they feel too firm, they may be overworked. Let them rest for 10 minutes before cooking to ensure even boiling.
Cook the Gnocchi
Bring 4 cups vegetable oil to 350°F in a deep pot. Add the gnocchi in batches, stirring gently to prevent sticking. Cook for 3-4 minutes until they float to the surface and are golden brown. Remove with a slotted spoon and drain on paper towels.
Don't overcrowd the pot—cook in batches if needed. The gnocchi are done when they puff slightly and develop a delicate crust. If they sink, they need more time. Keep them warm in a 200°F oven while you prepare the sage butter.
Prepare the Sage Butter Sauce
In a small saucepan, melt ½ cup unsalted butter over medium-low heat. Add ½ cup fresh sage leaves and 1 minced garlic clove (if using), cooking for 2-3 minutes until the sage is crispy and the butter turns golden. Strain through a fine-mesh sieve to remove the sage leaves, leaving behind the buttery, fragrant oil.
Return the strained butter to the pan and stir in ¼ cup freshly grated Parmesan cheese and ¼ tsp black pepper. Toss the cooked gnocchi in the sauce until evenly coated. Serve immediately, garnished with additional crispy sage leaves.
Pro Tips For Making Sweet Potato Gnocchi Recipe Sage Butter
- Boil Sweet Potatoes Until Fork-Tender: I used to pull them out when they looked done, but sweet potatoes need to be actually soft—no resistance when pierced with a fork. Overcooking? No, you’ll just mash them later. Aim for 15-20 minutes in salted water (yes, salt it like pasta water), then drain and let them steam-dry in the pot for 2 minutes. This step makes all the difference when shaping the gnocchi.
- Use a Mandoline for Even Dumplings: Rolling by hand works, but a mandoline gives you consistent thickness and saves your hands from frustration. If you don’t have one, use a bench scraper to slice the roasted sweet potato dough into ½-inch strips, then cut those into pieces. Uneven gnocchi? They’ll still cook, but the butter won’t cling as nicely.
- Don’t Overwork the Dough: Mix just until the flour comes together—overhandling makes gnocchi dense and chewy. I’ve ruined batches by kneading like pizza dough. Once the dough sticks to your fingers when pressed, it’s ready. Wrap it in plastic and rest for 10 minutes before rolling. Patience here = lighter, pillowy gnocchi.
- Brown the Butter First: Skip the plain butter—brown it with sage until it’s nutty and fragrant (about 3 minutes on medium-low). Let it cool slightly before tossing with the gnocchi, or you’ll scramble the eggs in the pan. The flavor jump is worth the extra 5 minutes. Trust me, your taste buds will notice.
Dietary considerations for this sweet potato gnocchi recipe sage butter
Vegetarian-Friendly Staple
This recipe is naturally vegetarian and packed with plant-based protein from the sweet potatoes, making it perfect for meat-free meals. The ½ cup unsalted butter and ¼ cup Parmesan cheese add richness without animal protein, while the sage butter sauce provides depth.
For a fully plant-based version, substitute the butter with vegan butter (like Miyoko's) and use nutritional yeast instead of Parmesan. 🌱
Gluten-Free Adaptation
To make this gluten-free, replace the 2 cups all-purpose flour with a 1:1 gluten-free flour blend like Bob's Red Mill. Add ½ tsp xanthan gum to improve elasticity, as gluten-free doughs lack natural binding.
The texture will be slightly denser but still tender. Test for doneness by cutting into a gnocchi—it should be soft inside with a slight resistance. 🥔
Low-Carb Option
For a lower-carb version, reduce the flour to 1 cup and add ½ cup almond flour for structure. The gnocchi will be lighter but still hold together. Balance the sweetness of the sweet potatoes with extra black pepper and a pinch of smoked paprika in the sage butter.
This adaptation cuts carbs by ~30% while keeping the dish satisfying. 💪
Allergen Awareness
This recipe contains gluten (wheat flour), dairy (butter and Parmesan), and eggs. For egg-free gnocchi, replace the 2 eggs with 2 tbsp ground flaxseed mixed with 6 tbsp water (let sit for 5 minutes to thicken).
Always check labels on gluten-free flours and dairy substitutes for cross-contamination risks. 🚨
Nut-Free & Seed-Free
This recipe is naturally nut-free and seed-free** when made as written. However, if using pre-made gluten-free flour blends, verify they’re processed in nut-free facilities. For extra security, prepare the dough in a clean workspace and avoid cross-contamination with nut products.
The sage butter sauce remains completely safe for nut allergies. ✨

Frequently asked questions
Can I use regular potatoes instead of sweet potatoes?
While you can substitute regular potatoes, the flavor and texture will differ significantly. Sweet potatoes add natural sweetness and a creamier texture that pairs beautifully with the sage butter. If you must use regular potatoes, roast them first to concentrate their flavor and reduce water content, then purée thoroughly for the best results.
Why does my dough keep sticking to my hands?
The dough will naturally be sticky—this is normal! Wet your hands slightly with water or olive oil while kneading to help prevent sticking. If it's extremely sticky, you may need to add 1-2 tbsp more flour, but avoid over-flouring, as this can make the gnocchi dense. Always work quickly and keep your surface lightly floured.
How do I know when the gnocchi are fully cooked?
Your gnocchi are done when they float to the surface of the boiling oil and develop a golden-brown crust (3-4 minutes). For extra certainty, taste one—it should be tender inside with a slight resistance, like al dente pasta. If they sink, they need more time, but don't overcook or they'll turn mushy.
Can I make the sage butter ahead of time?
You can prepare the sage butter up to 5 days in advance and store it in an airtight container in the fridge. However, the crispy sage leaves lose their texture when reheated, so it's best to make them fresh and toss the cooked gnocchi in the pre-made butter just before serving. For extra flavor, add fresh sage leaves to the butter right before tossing.
What if my gnocchi turn out too dense?
Dense gnocchi usually mean the dough was overworked or too much flour was added. For next time, handle the dough gently, avoid kneading excessively, and measure your flour precisely. If using gluten-free flour, the texture will naturally be denser—add ½ tsp xanthan gum to improve elasticity. Also, ensure your sweet potato purée is smooth and lump-free.
