Ingredients You’ll Need
- Leftover mashed potatoes: These are the base of the gnocchi, providing moisture and structure. Any smooth mashed potato, even sweet potatoes, can work here.
- Egg yolks: Add richness and help bind the dough. A flaxseed egg or 2 tablespoons of Greek yogurt can work in a pinch.
- All-purpose flour or gluten-free all-purpose flour: Acts as the primary binding agent for a smooth dough, creating structure. Gluten-free flour is a great alternative for those avoiding gluten.
- Nutmeg: Adds a warm, subtle flavor that enhances the overall taste. Cinnamon or allspice can be used for a different flavor profile.
- Sea salt, kosher salt
- Black pepper: Optional for taste.

How to Make Mashed Potato Gnocchi
Step 1: On a clean counter or large cutting board, combine the mashed potatoes, egg yolks, 1 ½ cups of flour, a pinch of nutmeg, and a pinch of salt.
Step 2: Use your fingertips to press and mix the potato mixture until it comes together to form a dough that feels firm but slightly soft under gentle pressure. If the dough is too sticky, sprinkle with a little more flour. Test the dough. Take a small piece and roll it on a floured surface into a rope about ½ inch in diameter. If it holds together, the dough is ready. If not, fold in a little more flour, press the dough several times, and test again.
Step 3: Lightly flour the counter. Divide dough into 4 equal pieces. Roll each piece out with your hands into a rope about ½ inch in diameter. Cut ½ inch pieces using a knife or bench scraper.
Step 4: Place them on a lightly floured baking sheet. You can leave them as is or make a traditional gnocchi shape with a gnocchi board, or the back of a fork.
Step 5: Bring a large pot of salted water to a boil. Add the gnocchi, in batches if needed depending on the pan size. Cook for 1 to 2 minutes or until they rise to the surface. Use a slotted spoon to remove them, and transfer them to a large bowl.
Step 6: Toss the gnocchi with your favorite sauce, butter, or olive oil, and finish with a sprinkle of Parmesan cheese.
Expert Tips
- Use smooth, lump-free mashed potatoes. The smoother your mashed potatoes, the better your gnocchi will hold together.
- Make this recipe vegan by replacing the egg yolks with 2 tablespoons of Greek yogurt or a flaxseed “egg” (1 tablespoon flaxseed meal mixed with 3 tablespoons water).
- Get creative with your mashed potato gnocchi by adding your favorite herbs and flavors to the dough. Finely chopped rosemary or thyme can add an earthy, aromatic touch, while grated Parmesan cheese brings a savory depth. You can also try mixing in a little garlic powder or smoked paprika for a flavor twist. Feel free to experiment – this is a forgiving recipe that lends itself to personalization!
Serving Suggestions
- Serve with a warm slice of whole wheat soda bread.
- Toss the gnocchi in a simple sage butter sauce, a hearty marinara, Bolognese, or a garlic-infused Alfredo sauce. Any sauce of your choice will be delicious!
- Serve on the side of a grilled steak or lemon-herb chicken for a delicious and flavorful meal.
Storage Tips
For best results, place any leftover cooked gnocchi in an airtight container and refrigerate for up to 2 days. Reheat by sautéing in a bit of butter or oil until warmed through.
Gnocchi freezes beautifully! Arrange uncooked gnocchi in a single layer on a baking sheet, freeze until firm, then transfer to a freezer-safe bag. Boil straight from frozen when you’re ready to enjoy them.
Recipe FAQs
Gradually add more flour, a tablespoon at a time, until the dough reaches the desired consistency. Be cautious not to add too much, as this can make the gnocchi dense.
It’s best to cook the gnocchi shortly after preparing the dough. However, you can shape the gnocchi, freeze them on a baking sheet, then transfer them to a freezer-safe bag for later use.
Overworking the dough or adding too much flour can result in dense gnocchi. Mix the ingredients until just combined and handle the dough gently to maintain a light texture.
