Leftover Mashed Potato Gnocchi three ways

Whether it’s the quiet aftermath of a holiday feast like Thanksgiving, a Sunday dinner, or merely an ordinary weeknight, the scenario is familiar: a generous bowl of mashed potatoes sits in the fridge. While delicious on their own, finding creative ways to repurpose them can be a culinary adventure. And when it comes to reinventing leftover mashed potatoes, quick-fix gnocchi stands out as an absolute must-try. This recipe isn’t just about using up leftovers; it’s about crafting a dish that feels special and indulgent with remarkable ease.

The Gnocchi Game Changer: Embracing Leftover Mashed Potatoes

Gnocchi often carries a reputation for being a labor-intensive dish, deterring many home cooks. The traditional method typically involves peeling and cooking potatoes, ricing them meticulously, then carefully mixing the delicate potato base with flour and egg. This process can be time-consuming, leading many to simply reach for a store-bought bag when the craving for those delightful, pillowy carbs strikes.

However, the beauty of this recipe lies in its ingenious shortcut: using pre-made, leftover mashed potatoes. This single step eliminates the most time-consuming parts of traditional gnocchi preparation. Your potatoes are already cooked, mashed, and often seasoned, providing a perfect foundation. This efficiency transforms gnocchi making from a daunting task into an accessible and enjoyable kitchen project.

Cutting mashed potato gnocchi

The secret weapon here is your existing leftover mashed potatoes. They are the ultimate shortcut for homemade gnocchi perfection. By starting with mashed potatoes, you bypass the entire cooking and ricing process, significantly cutting down on prep time. All that’s required is to add a little all-purpose flour and one large egg, and you are truly in business. This simple combination creates a pliable dough that’s ready to be transformed into delectable dumplings.

Crafting Your Perfect Pillows: The Easy Process

Making these gnocchi is surprisingly straightforward. It’s as simple as combining your chilled or room-temperature mashed potatoes with the flour and egg in a large bowl. Mix these ingredients until they are just combined, careful not to overmix, which can lead to tough gnocchi. The goal is a cohesive, slightly sticky dough.

Next, lightly flour your work surface – a clean countertop or a large cutting board works perfectly. Turn the gnocchi dough out onto the floured surface and gently knead it with your hands. The kneading process is minimal here; you’re simply working the dough until it comes together into a smooth ball and is no longer excessively sticky. The exact amount of flour needed can vary depending on the consistency of your original mashed potatoes, so it’s crucial to incorporate additional flour slowly, as needed, until you reach the desired texture. The dough should be soft, pliable, and easy to handle without clinging too much to your hands.

Once your dough ball is perfect, divide it into four equal pieces. Take each piece and roll it into a long, uniform rope, roughly 1-inch thick. Precision isn’t critical, but aim for consistency so your gnocchi cook evenly. Then, using a sharp knife or a bench scraper, cut each rope into 1-inch gnocchi nuggets. For that perfect, quintessential gnocchi shape and texture, gently roll each nugget off the back of a fork. The tines of the fork create delicate ridges on the gnocchi surface, which are not just for aesthetics but are essential for catching and holding onto your delicious sauce. With your gnocchi formed, all that’s left to do is choose your preferred sauce and cook them.

Sauce it Up: Perfect Pairings for Your Homemade Gnocchi

One of the joys of homemade gnocchi is its incredible versatility when it comes to sauces. I don’t discriminate when it comes to how one dresses these delightful mashed potato gnocchi. For classic Italian flavors, vibrant pesto, with its fresh basil, pine nuts, and Parmesan, or a rich, savory marinara sauce are both fantastic choices that complement the soft potato dumplings beautifully.

But if simplicity and elegance are your goals, you absolutely must try a brown butter sage sauce. This sauce is surprisingly easy to make and delivers an incredible depth of flavor. Simply melt unsalted butter in a saucepan over medium heat, allowing it to bubble and sizzle. Continue cooking, swirling occasionally, until the milk solids in the butter turn a beautiful golden brown and it develops a rich, nutty aroma. This transformation is what gives brown butter its distinctive, irresistible taste. Once browned, toss in a few fresh sage leaves – their earthy aroma perfectly complements the nutty butter – and a pinch of salt and freshly ground black pepper. The result is a simple yet sophisticated sauce that truly lets the gnocchi shine.

Beyond these, consider other possibilities: a creamy Alfredo sauce for decadence, a light garlic and olive oil drizzle with chili flakes for a subtle kick, or even a mushroom cream sauce for an earthy delight. The soft texture of the gnocchi pairs well with almost any sauce, making them a versatile canvas for your culinary creativity.

Tips for Gnocchi Success: Achieving the Perfect Texture

Making gnocchi from leftover mashed potatoes is generally forgiving, but a few tips can ensure your dumplings are consistently light and tender, never tough or gummy.

  1. Mashed Potato Consistency is Key: Not all mashed potatoes are created equal. For best results, use mashed potatoes that are relatively plain – ideally made with just potatoes, salt, and perhaps a little butter or milk. Mashed potatoes that are very wet or have a lot of added cream cheese or other mix-ins might require more flour and can sometimes yield a slightly heavier gnocchi. If your mashed potatoes are very loose, consider draining some liquid before mixing.
  2. Flour Wisely: The recipe calls for 1 cup of flour, plus more as needed. This “as needed” is crucial. Start with the initial amount and add extra flour in small increments (a tablespoon at a time) until the dough is just firm enough to roll without being overly sticky. Over-flouring is the most common mistake, leading to dense, rubbery gnocchi. The dough should still feel soft and tender.
  3. Gentle Kneading: Once the ingredients are combined, resist the urge to vigorously knead the dough. Just a minute or two of gentle kneading on a floured surface is enough to bring it together into a cohesive ball. Over-kneading develops the gluten in the flour, making the gnocchi tough.
  4. Test Before You Commit: If you’re unsure about the dough’s consistency, boil a single gnocchi first. If it falls apart, knead in a tiny bit more flour. If it’s too dense, you might have added too much flour, though it’s harder to correct at that stage. This test helps you adjust before cooking the whole batch.
  5. Don’t Overcrowd the Pot: When boiling, cook the gnocchi in batches to avoid overcrowding the pot. This ensures the water stays at a rolling boil and the gnocchi cook evenly.

Ingredients 

  • 1 cup leftover mashed potatoes, chilled or room temp
  • 1 cup all-purpose flour, plus more as needed
  • 1 large egg
  • Sauces for serving, such as marinara, brown butter or pesto

Instructions 

  • In a large bowl, combine the mashed potatoes, 1 cup all-purpose flour, and the egg. Mix until all ingredients are just combined to form a cohesive dough. Be careful not to overmix.
  • Lightly flour your work surface. Turn the gnocchi dough out onto the floured surface and gently knead it with your hands until it comes together into a smooth ball and is no longer excessively sticky. Slowly incorporate additional flour as needed, a tablespoon at a time, until the dough is pliable and easy to handle without clinging to your hands.
  • Divide the dough ball into four equal pieces. Roll each piece into a 1-inch-thick rope. Using a sharp knife or bench scraper, cut each rope into 1-inch gnocchi nuggets. For classic ridges, gently roll each gnocchi off the back of a fork.
  • Bring a large pot of generously salted water to a gentle boil. Carefully add the gnocchi to the boiling water, cooking them in batches to avoid overcrowding the pot. Cook until they float to the top, which usually takes about 2-3 minutes. Once they float, let them cook for another 30 seconds before removing them with a slotted spoon. Serve immediately with your preferred sauce.

Kelly’s Note:

  • The consistency of leftover mashed potatoes can vary greatly depending on how they were originally made. This will determine the exact amount of flour you need. Always start with the recommended amount (1 cup) and then add more flour sparingly, as needed, until the dough reaches a pliable, non-sticky consistency that is easy to work with.
