Purple Sweet Potato Gnocchi with Creamy Parmesan Sauce, Danablu & Pistachios

Purple Sweet Potato Gnocchi with Creamy Parmesan Sauce, Danablu & Pistachios

Hello Everyone and a Happy November to all! I honestly didn’t think that I would be spending my birth month still under general community quarantine, but at least it means that we’re still taking safety precautions… Or are we really? I went grocery shopping over the weekend, and it seemed like people weren’t keeping their distances. I was queuing up at the pharmacy and though there were evident markings on the floors on where you should stand, this one lady behind me kept standing right behind me. The security guard had to tell her to follow the markings.

Mini introductory tangent aside, gnocchi (pronounced ni-yok-ee; singular gnocco) are a variety of pasta consisting of various thick, small, and pillow soft dough dumplings that are primarily made by combining potatoes, flour, and egg, but may also be made from semolina, ordinary wheat flour, breadcrumbs, cornmeal, or similar ingredients. The dough for gnocchi is most often rolled out before it is cut into small pieces about the size of a wine cork. The little dumplings are then pressed with a fork or a cheese grater to make ridges that can hold sauce. Alternatively, they are simply cut into little pillows.

Gnocchi are generally homemade in Italian and Italian-immigrant households. They may also be bought fresh from specialty stores. Packaged gnocchi are widely available either refrigerated, dried, or frozen, if industrially produced. Like many Italian dishes, gnocchi have considerable variation in recipes and names across different regions. Gnocchi are commonly cooked on their own in salted boiling water and then dressed with various sauces depending on the type of gnocchi and recipe used. Common accompaniments of gnocchi include melted butter with sage, and pesto.

For tonight’s recipe, I decided to put a little spin to it by using sweet potatoes instead or regular potatoes. In addition, since it’s a new month and therefore a new colour theme on Amcarmen’s Kitchen, I specifically used Japanese purple sweet potatoes that I sourced from PruTazan, for my last colours of the rainbow theme for the year! That’s right, for the month of November and December, I will be sharing violet recipes with you guys.

Also known as Murasaki Imo, which means “purple potato” in Japanese, contains dietary fiber, vitamins A and C, and minerals like calcium, magnesium, potassium, and zinc. The flesh also contains anthocyanin, a naturally occurring antioxidant that gives the tuber its purple hue. They are used in a variety of culinary applications including desserts and snack foods and are valued for their sweet flavour and high antioxidant content. They are also commonly dried and turned into powder for use as a natural food colouring.

Purple Sweet Potato Gnocchi with Creamy Parmesan Sauce, Danablu & Pistachios Ingredients



For the sweet potato gnocchi

  • 1 kg purple sweet potatoes
  • 3/4 cup all purpose flour, plus more if needed as well as for dusting
  • 1 large free-range egg
  • Salt and freshly ground pepper, to taste

For the creamy parmesan sauce

  • 250ml all purpose cream
  • 3 garlic cloves, finely minced
  • 1 small red onion, finely minced
  • 1/4 cup parmesan cheese, grated
  • Salt and freshly ground pepper, to taste
  • Chives, finely chopped
  • Danablu Cheese, crumbled
  • Pistachios, roughly chopped


  1. Sweet Potato Gnocchi: Bake the sweet potatoes in a preheated oven at 230C (450F or gas mark 8), for 45 minutes or until completely tender when pierce with a fork. Once done, set aside to cool.

Note: Japanese purple sweet potatoes are best steamed or roasted. When boiled, they will lose their purple hue. So to retain their vibrant colour, they should be roasted or steamed.

  1. Once cool enough to handle, peel the skins off the sweet potatoes and in a large mixing bowl, roughly mash them using a fork. Add the flour, egg and season with a touch of salt and freshly ground black pepper. Bring the mixture together to form a dough.
  2. Gently fold and press the dough a couple of times, adding flour as necessary if the dough feels sticky. Turn the dough out onto a work surface lightly dusted with flour. Cut the dough into four equal parts and form each quarter into a ½-inch diameter log using the palm of your hands.
  3. Cut each log into 1-inch pieces and then press over the tine of a fork to create ridges. Transfer to a baking sheet dusted with flour and repeat with the remaining dough. I managed to make about 76 pieces of gnocchi with this recipe, more or less depending on how you roll them out/cut them.

  1. Bring a large pot of generously salted water to a boil. Working in batches, add the gnocchi to the pot, gently stirring once or twice to prevent them from sticking. Cook until the gnocchi floats to the surface, about 3-5 minutes, and then cook for an additional 30 seconds. Remove using a slotted spoon and transfer to a tray lightly drizzled with oil. Set aside.
  2. Creamy Parmesan Sauce: Heat about a tablespoon of cooking oil over medium-high, in a medium-sized pan. Add garlic and sauté until fragrant, about 30 seconds. Immediately add in the onions and continue to sauté until fragrant and slightly golden in colour and onions have softened and begin to go translucent, a further 45 seconds.
  3. Add the cream and season with a touch of salt and freshly ground pepper. Mix and bring to a gentle simmer. Once simmering, add in the parmesan cheese. Mix until the cheese has melted and then remove from the heat.
  4. Assemble: Heat 2 tablespoons of cooking oil in a large frying pan over medium-high. Working in batches again, add the gnocchi to the pan and lightly fry until golden brown in colour.
  5. Spread the creamy parmesan sauce on a serving dish, and place the pieces of fried gnocchi on top. Add crumbles of Danablu cheese* (or any other type of blue cheese) and top with roughly chopped pistachios, and chives.
  6. Serve immediately and enjoy!

This recipe for Purple Sweet Potato Gnocchi creates a vibrant and eye-catching dish that is as visually pleasing as it is delicious. You get the best of both worlds with the light, soft-pillowy interior and golden-crispy exterior in every mouthful. These gnocchi are a touch sweeter than those made from regular potatoes, and therefore are best complimented by salty and savoury flavours, like a Creamy Parmesan Sauce. Sharp, rich, and bold especially with the danablu cheese. Balance it out with a fresh squeeze of lemon juice to cut through the creaminess, and you’ve got yourself a killer dish!
