If you’re looking for a dish that is as visually stunning as it is comforting, look no further than Purple Sweet Potato Gnocchi. Unlike traditional russet gnocchi, these vibrant dumplings offer a subtle, earthy sweetness and a texture that is incredibly light and airy. The deep violet color—thanks to the antioxidant-rich Stokes or Okinawan sweet potatoes—creates a “wow” factor that makes this recipe a favorite for dinner parties and cozy date nights alike.

Paired with a classic brown butter sauce, crispy fresh sage, and the crunch of toasted pine nuts, this dish strikes the perfect balance between sophisticated flavor and rustic Italian soul. Let’s dive into how you can master this homemade pasta from scratch.

Ingredients

For the Gnocchi:

• Purple Sweet Potatoes: 1 lb (approx. 2 medium potatoes). Stokes or Okinawan varieties work best for their starchy texture.
• All-Purpose Flour: ¾ cup to 1 cup (plus extra for dusting). Note: The amount varies based on the moisture of your potatoes.
• Egg: 1 large, lightly beaten (helps with binding and structure).
• Sea Salt: 1 teaspoon.
• Nutmeg: A pinch (optional, for depth of flavor).

For the Sauce & Garnish:

• Unsalted Butter: 6 tablespoons.
• Fresh Sage Leaves: 12–15 leaves.
• Pine Nuts: 3 tablespoons.
• Parmesan Cheese: Freshly grated, for serving.
• Black Pepper: Freshly cracked, to taste.

Step-by-Step Instructions

1. Prepare the Potatoes

Preheat your oven to 400°F (200°C). Scrub the purple sweet potatoes and pierce them several times with a fork. Place them directly on the oven rack or a baking sheet and bake for 45–60 minutes until a knife slides through easily. Pro Tip: Baking rather than boiling prevents the potatoes from absorbing excess water, ensuring your gnocchi aren’t gummy.

2. Mash and Rice

While still warm, peel the skins off the potatoes (careful, they’re hot!). For the lightest texture, pass the potatoes through a potato ricer into a large mixing bowl. If you don’t have a ricer, mash them thoroughly with a fork until no lumps remain. Let the mash cool for about 5–10 minutes.

3. Form the Dough

Make a well in the center of the potato mash. Add the beaten egg, salt, nutmeg, and about ½ cup of the flour. Gently fold the ingredients together using your hands or a bench scraper. Gradually add more flour, a tablespoon at a time, until a soft, slightly tacky dough forms. Stop as soon as it stops sticking to your hands. Over-kneading will make the gnocchi tough.

4. Roll and Cut

Divide the dough into 4 equal pieces. On a floured surface, roll each piece into a long “rope” about ¾-inch thick. Use a knife or bench scraper to cut the rope into 1-inch pieces. You can leave them as rustic pillows or roll them over a gnocchi board (or the tines of a fork) to create ridges that catch the sauce.

5. Toast the Pine Nuts

In a dry skillet over medium-low heat, add the pine nuts. Shake the pan frequently for 3–5 minutes until they are golden brown and fragrant. Remove from the pan immediately to prevent burning and set aside.

6. Boil the Gnocchi

Bring a large pot of heavily salted water to a gentle boil. Drop the gnocchi in batches. They are done when they float to the surface (usually 2–3 minutes). Use a slotted spoon to transfer them directly into the waiting sauce pan.

7. The Sage Butter Finish

In a large skillet over medium heat, melt the butter. Once it starts to foam and turn slightly brown (smelling nutty), add the fresh sage leaves. Fry for 1 minute until the leaves are crisp. Add the cooked gnocchi to the skillet and toss gently for 2 minutes to coat and slightly crisp the edges. Season with black pepper.

8. Serve

Plate the gnocchi immediately. Top with the toasted pine nuts, a generous sprinkle of grated Parmesan, and the crispy sage leaves.

Fact-Check: Accuracy & Success Tips

• Temperature: Baking potatoes at 400°F is the industry standard for gnocchi-making to dehydrate the starch, which results in a lighter dumpling.
• Float Rule: The “float rule” is an accurate indicator of doneness for fresh pasta. Because the gnocchi are small, they cook almost instantly once the internal temperature reaches a point where the starch gelatinizes and air is trapped.
• Pine Nut Safety: Pine nuts should be toasted over medium-low heat; they have high oil content and can go from golden to burnt in seconds.
• Purple Potatoes: Ensure you are using true purple sweet potatoes (like Stokes) rather than Ube (purple yam), as Ube has a higher moisture content and requires significantly more flour to hold its shape.
