Ingredients & Smart Swaps

Here's what you'll need to make this sweet potato gnocchi. Each ingredient plays a role, so read on for easy substitutions.

• 1 medium sweet potato (about 12 oz / 340 g): The star of the show. Look for a firm, unblemished potato. You can also use leftover roasted sweet potato—just mash it smooth.
• ½ cup grated Parmesan cheese (about 50 g): Adds salty, nutty depth. For a vegetarian version, use vegetarian Parmesan or a hard aged cheese labeled vegetarian. Pecorino works too if you're not strictly vegetarian.
• 1 large egg: Binds the dough and adds richness. For an egg-free version, substitute 1 tablespoon ground flaxseed mixed with 3 tablespoons water (let it sit 5 minutes).
• 2 cups all-purpose flour (about 240 g), plus more for dusting: The structure. Start with 1¾ cups and add more as needed—sweet potato moisture varies.
• 2 tablespoons unsalted butter: For the sage brown butter sauce. Use vegan butter if dairy-free.
• 2 fresh sage leaves (or more to taste): Crispy sage is the aromatic finish. Dried sage works in a pinch—use ½ teaspoon.
• Extra Parmesan for topping: Because more cheese is always a good idea.

Pro-Tip: Don't double the recipe unless you have a big crowd. The dough is best used fresh, and a single batch already makes plenty of gnocchi for four hungry people.

Step-by-Step Cooking Guide

1. Bake the Sweet Potato

Preheat your oven to 400°F (200°C). Prick the sweet potato all over with a fork—about 8 to 10 pokes. Place it on a baking sheet and bake for 40 minutes, until a knife slides in with no resistance. (Short on time? Microwave on high for 5 minutes, turning halfway, until tender.) Let it cool for at least 5 minutes, then peel off the skin. It should slip right off.

How to verify success: The potato should be completely soft and easily pierced. If it's still firm, bake another 5–10 minutes.

2. Mash the Sweet Potato

In a large bowl, mash the peeled sweet potato with a potato masher or fork until completely smooth. Any lumps will make the dough tear, so take a minute to get it velvety.

3. Make the Dough

Add the grated Parmesan, egg, and 1¾ cups of flour to the mashed sweet potato. Mix with a wooden spoon or your hands until a shaggy dough forms. Knead gently in the bowl, adding more flour a tablespoon at a time, until the dough is firm and no longer sticky. It should feel like soft playdough—not tacky.

How to verify success: Pinch off a small piece and roll it. If it sticks to your fingers, add a little more flour. If it cracks, add a teaspoon of water.

4. Shape the Gnocchi

Lightly flour your work surface. Divide the dough into four equal parts. Take one part and roll it into a long rope about 1 inch (2½ cm) thick. Cut the rope into ½-inch (1 cm) pieces.

To create the classic ridges, hold a fork with the tines facing down (or use a gnocchi board). Place a piece of dough on the fork and gently press and roll it with your thumb so it curls around the tines, forming a corkscrew shape. Set the shaped gnocchi on a floured baking sheet. Repeat with the remaining dough.

Pro-Tip: Keep your work surface and hands lightly floured to prevent sticking, but don't over-flour—too much flour makes the gnocchi dense.

5. Boil the Gnocchi

Bring a large pot of salted water to a boil. Add the gnocchi in batches—don't overcrowd. They're done when they float to the top, about 1 to 2 minutes. Scoop them out with a slotted spoon and drain in a colander.

How to verify success: The gnocchi should be tender but not mushy. Bite into one—it should have a slight chew and no raw flour taste.

6. Make the Sage Brown Butter

In a large skillet over medium heat, melt the butter. Add the sage leaves and cook for about 1 minute, swirling the pan, until the butter smells nutty and turns golden brown. Be careful not to let it burn—if it starts to darken too quickly, lower the heat.

7. Pan-Fry the Gnocchi

Add the drained gnocchi to the skillet with the sage butter. Toss gently to coat. Cook for 2 to 3 minutes, tossing occasionally, until the gnocchi are lightly golden and crispy on the edges.

How to verify success: The gnocchi should have golden-brown spots and smell irresistible. Taste one—the outside should be slightly crisp, the inside soft.

8. Serve

Transfer to plates and shower with extra grated Parmesan. Garnish with the crispy sage leaves. Serve hot.

Chef's Secrets for Success

• Keep the dough light: Handle it as little as possible. Over-kneading develops gluten and makes gnocchi tough.
• Flour your fork: A quick dust of flour on the fork prevents sticking when shaping.
• Don't skip the ice bath: If you're not cooking the gnocchi right away, transfer the boiled gnocchi to an ice bath to stop the cooking, then drain and toss with a little oil to prevent sticking.
• Brown butter is your friend: Watch it closely—it goes from nutty to burnt in seconds. Have the gnocchi ready to go before you start the butter.

Troubleshooting & Common Mistakes

• Dough too sticky? Add flour one tablespoon at a time until it's workable. The humidity and moisture of your sweet potato affect this.
• Gnocchi falling apart in the water? The dough may be too wet. Add a little more flour and re-shape. Also, make sure the water is at a gentle boil, not a rolling one.
• Gnocchi dense and heavy? You likely added too much flour or over-kneaded. Next time, start with less flour and add only as needed.
• Butter burned? Start over with fresh butter and lower the heat. Brown butter should be golden, not black.

Storage, Make-Ahead & Reheating

Make-ahead: Shape the gnocchi and freeze on a floured baking sheet until firm, then transfer to a zip-top bag. Boil from frozen—they'll take an extra minute or two.

Storage: Cooked gnocchi can be refrigerated in an airtight container for up to 3 days. Reheat in a skillet with a little butter over medium heat until warmed through and crispy again.

Freezing: Freeze boiled and drained gnocchi in a single layer, then bag. Reheat directly in a skillet—no need to thaw.

Frequently Asked Questions

Can I use a different type of potato?

Yes! Russet or Yukon Gold potatoes work beautifully. Just adjust the flour—russets are drier, so you may need less.

Is this recipe gluten-free?

Not as written, but you can substitute a gluten-free all-purpose flour blend. The texture will be slightly different but still delicious.

Can I make this vegan?

Absolutely. Use vegan Parmesan, a flax egg, and vegan butter. The result is just as tasty.

What do I serve with sweet potato gnocchi?

A simple green salad and crusty bread make a lovely meal. For a heartier dinner, add roasted vegetables or a side of garlicky greens.
