Duchess potatoes are a fun and delicious way to use up leftover Southern-style mashed potatoes after the holidays or any Southern get-together. They are piped onto a baking sheet lined with parchment paper and oven-baked for 20 minutes. These fluffy potatoes are made with minimal ingredients and turn leftovers into a beautifully golden, crispy side.
The Never-Ending Amount of Mashed Potatoes
Growing up in a Southern home with a mom who was born in Alabama and grew up in Mississippi - she taught me lots and lots of different things about being a Southern cook. One of those things is there is no such thing as making southern-style mashed potatoes for just like 5 people. Nope. The only way to make them is for like 50 minimum or a small army.
I am completely joking, but every time I make them now or she made them growing up it made A TON. And have you ever peeled enough potatoes for 150 people? Because I have helped in that endeavor with my parents catering company and shew - that is some serious work! 😂
But when you have the inevitable leftovers - I have come up with so many yummy uses for leftover mashed potatoes like leftover mashed potato pancakes and leftover mashed potato biscuits. But these duchess potatoes - oh yum!! They feel like such a fancy version of potato. Just whipped up with an egg, flour, and salt. Some cheddar cheese if you're feeling frisky that day. Piped into dainty little mounds and baked until golden brown in the oven for 20 minutes.
They are so cutesy. So demure. So very mindful of a sophisticated way to transform those leftovers into something spectacular. (BRB while I am laughing at myself over that sentence 😂). Let me show you how to do it!
First, the mashed potatoes.
⭐️A note about mashed potatoes⭐️ ... I recently had a reader email me about this recipe saying that it didn't quite turn out and I helped troubleshoot with her back and forth. We came to the conclusion that mashed potatoes, depending on how they are made, can contain different levels of moisture. AKA - I may use more sour cream and milk in mine than you do or vice versa. Resulting in a different quantity of flour needed. Her's weren't as "liquidy" (for lack of a better word) than mine so a ½ cup of flour was too much and resulted in dense bland tasting potato mounds. Since then, I now recommend starting with ¼ cup of flour first and then adding more as needed. You want it to be a thicker consistency than your mashed potatoes but thin enough to pipe out.
Next, make the batter.
Now lets pipe!
⭐️Piping Tips⭐️ I will either use a Wilton 1M star tip or a wide open star tip when piping these. I have found the wider opening makes it easier to pipe the thicker filling. (*affiliate links*)
Once they are finished baking you can brush the tops with a little melted butter, a sprinkle of salt, some freshly cracked black pepper, and even some diced chives to make it over the top. It is so yummy and so very fancy feeling. I know you will love these - and it won't even feel like you're repurposing a recipe!
