If you’re ready to impress your family or guests with a vibrant and gourmet dish, this Purple Sweet Potato Gnocchi is the perfect choice. It’s a visually stunning meal that’s both delicious and packed with nutrients.
Ingredients
For the Gnocchi:
- 2 medium purple sweet potatoes (about 1 pound)
- 1 cup all-purpose flour (plus extra for dusting)
- 1 egg yolk (optional for added richness)
- 1/2 teaspoon salt
- 1/4 teaspoon nutmeg (optional, for flavor)
For the Sage Butter Sauce:
- 1/4 cup unsalted butter
- 6-8 fresh sage leaves
- Salt and pepper, to taste
- Grated Parmesan cheese (optional, for garnish)
Instructions
Prepare the Purple Sweet Potatoes
- Boil or Bake the Potatoes: Peel the purple sweet potatoes and cut them into chunks. Boil them in a pot of salted water for 15-20 minutes until tender. Alternatively, bake them in the oven at 400°F (200°C) for 45 minutes until soft.
- Mash: Mash the cooked sweet potatoes with a fork or potato masher until smooth. Let them cool completely before proceeding.
Make the Gnocchi Dough
- Combine Ingredients: In a mixing bowl, add the cooled mashed purple sweet potatoes, flour, salt, and nutmeg. If using, add the egg yolk for a richer dough.
- Mix Gently: Use your hands to combine the ingredients into a soft, slightly sticky dough. Avoid overmixing to keep the gnocchi light and tender.
- Knead Lightly: Sprinkle flour onto a clean surface and knead the dough gently for 1-2 minutes until it holds together.
Shape the Gnocchi
- Roll Out the Dough: Divide the dough into four portions. Roll each portion into a long rope about 3/4-inch thick.
- Cut into Pieces: Using a knife, cut the ropes into 1-inch pieces. For a traditional gnocchi shape, roll each piece over the back of a fork or a gnocchi board to create ridges.
- Dust with Flour: Lightly dust the gnocchi pieces with flour to prevent sticking.
Cook the Gnocchi
- Boil Water: Bring a large pot of salted water to a gentle boil.
- Cook in Batches: Drop the gnocchi into the boiling water in small batches. They are done when they float to the surface, usually in 2-3 minutes.
- Remove and Drain: Use a slotted spoon to transfer the cooked gnocchi to a plate lined with paper towels.
Make the Sage Butter Sauce
- Melt Butter: In a large skillet, melt the butter over medium heat.
- Add Sage Leaves: Add the fresh sage leaves to the melted butter and let them crisp up, about 1-2 minutes. Stir occasionally to prevent burning.
- Season: Add salt and pepper to taste.
Combine and Serve
- Toss Gnocchi in Sauce: Add the cooked gnocchi to the skillet with the sage butter sauce. Gently toss to coat each piece in the fragrant butter.
- Plate and Garnish: Serve the gnocchi hot, garnished with freshly grated Parmesan cheese and a sprinkle of black pepper.
Tips for Perfect Gnocchi
- Avoid Overloading the Dough: Use just enough flour to hold the dough together. Too much flour can make the gnocchi dense and heavy.
- Test the Dough: Cook a small piece of gnocchi first to ensure it holds its shape. If it falls apart, add a little more flour to the dough.
- Keep the Water Gentle: Avoid a rolling boil, as it can break the gnocchi.
