Leftover mashed potatoes finally got interesting. Stuff them with mushrooms, fry them crisp, and pretend this was always the plan.
I made these after overcooking dinner for two. Shocking plot twist: the “mistake” vanished faster than the main dish.
They’re crispy, cozy, and a little smug. Add sour cream and green onions, because apparently pancakes need accessories.
Leftover Mashed Potato Pancakes Stuffed with Mushrooms
EQUIPMENT (PAID LINKS)
- Plate
- Paper towels
Ingredients
- 3 tablespoons vegetable oil divided
- 1 medium onion finely chopped
- 8 ounces mushrooms finely chopped
- Salt to taste
- Black pepper to taste
- 4 cups cold leftover mashed potatoes
- 1 large egg
- 1 tablespoon all-purpose flour
- ¼ cup cornmeal plus ½ cup for coating
- ½ cup sour cream for serving
- 2 tablespoons chopped green onions for serving
Instructions
- Cook Mushroom Filling: Heat 1 tablespoon of vegetable oil in a large skillet over medium heat. Add the chopped onion and mushrooms, then cook for 8 to 10 minutes, stirring often, until the mushrooms are soft and the mixture looks golden.
- Season Filling: Add salt and black pepper to taste. Stir well, then remove the mushroom mixture from the heat and let it cool slightly.
- Make Potato Dough: Place the cold mashed potatoes in a mixing bowl. Add the egg, all-purpose flour, and ¼ cup cornmeal, then mix until the potato mixture holds together like a soft dough.
- Season Potato Dough: Taste the potato mixture and add a little salt and black pepper if needed. Mix again until evenly combined.
- Shape Potato Disk: Sprinkle some of the remaining cornmeal onto a clean work surface or plate. Scoop about ⅓ cup of the potato mixture and flatten it into a round disk.
- Add Mushroom Filling: Place about 1 tablespoon of the mushroom filling in the center of the potato disk. Do not overfill, or the pancake may split while cooking.
- Seal Pancake: Fold the potato mixture around the filling and gently pinch the edges closed. Shape it into a thick, flat pancake.
- Coat Pancake: Coat both sides of the stuffed pancake with cornmeal. Repeat with the remaining potato mixture and mushroom filling.
- Fry Pancakes: Heat the remaining 2 tablespoons of vegetable oil in the skillet over medium heat. Cook the pancakes for 3 to 4 minutes per side, or until golden brown and crisp.
- Drain Pancakes: Transfer the cooked pancakes to a plate lined with paper towels. Let them rest for 1 to 2 minutes so they firm up slightly.
- Serve: Serve the potato pancakes warm with sour cream and chopped green onions.

Leftover Mashed Potato Pancakes Stuffed with Mushrooms: Tiny Crispy Miracles for People Avoiding Responsibility
These tips are here to save your pancakes, your skillet, and possibly your mood. Because mashed potatoes are dramatic, and we respect that.
Start with Cold Mashed Potatoes
Warm mashed potatoes are needy and sticky, which is not the energy we want here. Cold mashed potatoes behave better, like they’ve had time to think about their choices. If yours are extra creamy or loose, stir in a little more cornmeal or flour until the mixture can hold its shape.
Don’t Overfill the Pancakes
I know, the mushroom filling is the whole point, and restraint is boring. But too much filling makes the pancakes split open in the skillet like they’re revealing family secrets. One generous tablespoon is usually plenty.
Chop the Mushrooms Small
Big mushroom chunks make the filling harder to seal inside the potato dough. Chop them finely so they tuck in nicely and cook down evenly. This is not the moment for rustic confidence.
Use Cornmeal for Extra Crunch
Cornmeal gives the outside that golden, crispy edge that makes these feel less like leftovers and more like a plan. Breadcrumbs can work too, but cornmeal has that tiny gritty crunch that says, “Yes, I absolutely meant to do this.”
Swap the Mushrooms If Needed
No mushrooms? Try finely chopped spinach, cooked cabbage, caramelized onions, or shredded cheese. Just make sure any swap is cooked and not watery. Wet fillings are how good potato pancakes become sad potato blobs.
Add Cheese Because Obviously
A little shredded mozzarella, cheddar, or Parmesan inside the filling is never a bad idea. Keep it modest, though, unless you enjoy scraping melted cheese off your skillet while questioning your life choices.
Keep the Heat at Medium
Medium heat is your friend here. Too hot, and the outside browns before the inside firms up. Too low, and the pancakes soak up oil like they’re training for something. Golden and crisp is the goal, not deep-fried regret.
Use a Nonstick or Well-Seasoned Skillet
Potato pancakes love to stick if given the opportunity. A nonstick skillet or a well-seasoned cast iron pan makes the whole process less annoying, which is really all we’re asking from dinner.
Make Them Ahead
You can shape the pancakes a few hours ahead and keep them covered in the fridge. Fry them right before serving so they stay crisp. Future you will feel wildly organized, even if present you is just avoiding dishes.
Store Leftovers the Right Way
Store cooked pancakes in an airtight container in the fridge for up to 3 days. Reheat them in a skillet or air fryer to bring back the crispiness. The microwave works, technically, but it also turns them soft, and we don’t need to reward that behavior.
Freeze Before Frying
For the best freezer shortcut, shape and coat the pancakes, then freeze them on a tray until firm. Transfer them to a freezer bag and cook from frozen over medium-low heat, adding a few extra minutes. It’s meal prep, but without the smug little containers.
Serve with Something Tangy
Sour cream is classic, but Greek yogurt works if you want more tang. Applesauce is surprisingly good too, especially if you like that sweet-savory thing. Hot sauce is also welcome, because some of us believe every potato deserves drama.
