Step 1

Place mashed potatoes in a mixing bowl. They should be cold, so this is a great way to use up leftover potatoes.

Step 2

Add egg and flour and mix until the dough comes together. Place dough onto a floured surface and divide into two parts. Roll one part of the dough into a long log and slice into 1.5 to 2" dumplings.

Step 3

In a large saucepan or pot, boil water and add 1 teaspoon of salt. Add 5 to 8 dumplings at a time to the boiling water and cook until they start to float at the top. Remove and place on a plate. Repeat with remaining dumplings.

Step 4

You can serve the dumplings right away as a side dish or follow the suggestion below.

Step 5

In a skillet, heat up 1 tablespoon of olive oil and 1 tablespoon of butter. Add cooked dumplings and cook until golden brown. Remove onto a plate. Add 2 minced garlic cloves, 1 small yellow onion (chopped), 4 slices of bacon (chopped) and 4 white mushrooms (washed, sliced). Saute until fragrant and the bacon is crispy. Toss with dumplings and serve.
