Expert Tips That I Recommend
- When boiling my gnocchi, I always use a big pan. Even if you are using a small pan, do not overcrowd it.
- Overcrowding with too many gnocchi at once will lead to undercooked and overcooked gnocchi. Also, it will be challenging to flip and manage, so it is best to limit the amount of gnocchi in your pan.
- You can use a gnocchi board to give the gnocchi the traditional shape; however, I use the back of the fork and roll it to provide it with the gnocchi shape.
- Since I am using mashed potato leftovers, they can get runny. But you can eye the measurements while adding flour and ensure it is well kneaded until it is soft and bounces back for consistency.
- While rolling the gnocchi dough, I like to dust the surface with flour to make it easier to work with.
- If you use refrigerated mashed potatoes, let them cool at room temperature. This will allow you to mix the flour properly and reduce cooking time.
- If you are worried your Leftover Mashed Potato Gnocchi will be bland, you can add black pepper, nutmeg, cinnamon, or allspice to this recipe.

- Oven: I use my oven for a big Leftover Mashed Potato Gnocchi batch. I preheat my oven to 350 degrees F, add the leftovers to a baking tray, garnish with cheese and herbs, cover it with foil, and bake it for 5-10 minutes. You can also add a few cooking sprays to the baking dish to prevent the gnocchi from drying out.
- Microwave: The microwave is also a good option for reheating gnocchi. I start by placing it in a microwave-friendly bowl. Then, you can cover it with a paper towel and heat it for 20-30 seconds at medium heat.
