These mashed potato bacon cakes turn a cold bowl of leftovers into golden, crisp edged patties loaded with sharp cheddar, smoky bacon, and sliced scallions. They come together in about 35 minutes and use ingredients you probably already have in the fridge.
Instead of reheating the same side dish for a third night, you shape the potatoes into little cakes, press them into panko, and pan fry them until deeply browned. The inside stays soft and cheesy while the outside crunches, which makes the patties a happy fit for breakfast, a light lunch, or a quick dinner side.

Why This Mashed Potato Bacon Cakes Recipe Works
Cold potatoes are the secret. Chilled leftovers are firm and a little dry, so they hold together when shaped, and the starch has already set. Warm or freshly made potatoes turn sticky and slump in the pan.
A small amount of flour and one egg act as the binder, while the panko coating does the heavy lifting for crunch. You get a crisp shell without deep frying, and the oil needed is only a thin layer in the skillet.
Cooking the bacon first matters for both flavor and food safety. Crisp bacon bits stay crunchy inside the patties, and the rendered smokiness carries into the potato mixture. Raw bacon would not cook through in the two or three minutes each side needs.
Ingredients for Mashed Potato Bacon Cakes
- 2 1/4 cups cold leftover mashed potatoes, made with butter and milk
- 8 oz bacon, diced
- 1 cup shredded sharp cheddar cheese
- 1/2 cup thinly sliced scallions (about 4)
- 1 large egg
- 1/3 cup all purpose flour
- 1/4 tsp kosher salt
- 1/4 tsp black pepper
- 2 cups panko breadcrumbs, for coating
- 1/4 cup vegetable oil, for pan frying
Cold mashed potatoes. Use potatoes that spent at least a few hours in the refrigerator. Plain or buttery both work. If yours were made with a lot of milk and feel loose, stir in an extra tablespoon of flour.
Bacon. Dice the slices into small pieces so they spread evenly through the mixture, then cook until crisp and drain well on paper towels. Thick cut bacon gives the meatiest bites.
Sharp cheddar. Shred it from a block for better melting. Mozzarella or Gouda also work and give a milder, stretchier center.
Scallions. The green and white parts add a gentle onion bite that balances the rich bacon and cheese.
Egg and flour. These bind the mixture so the patties do not crumble when you flip them.
Panko. The coarse crumbs fry up lighter and crunchier than fine breadcrumbs. Plain flour makes a softer, less crunchy crust if you run out.
How to Make Mashed Potato Bacon Cakes
1. Cook the bacon. Fry the diced bacon in a large skillet over medium heat for 7 to 8 minutes, stirring now and then, until crisp. Move it to a paper towel lined plate to drain and cool, then wipe the skillet clean.
2. Mix the base. In a large bowl, stir together the cold potatoes, cooled bacon, cheddar, scallions, egg, flour, salt, and pepper until just combined. Overmixing makes the potatoes gummy, so stop as soon as no dry flour remains.
3. Set up the coating. Spread the panko on a large plate or rimmed baking sheet. Line a second sheet with paper towels for draining the cooked patties.
4. Shape the patties. Scoop 1/4 cup of the mixture onto the panko and pat it into a round about 2/3 inch thick. Flip to coat the other side and set it aside. You should end up with about 12 patties. If the mixture feels soft, chill the shaped patties for 15 minutes.
5. Pan fry the first batch. Heat half of the oil in the skillet over medium high heat until it shimmers. Cook six patties for about 3 minutes per side, until deep golden brown and crisp.
6. Drain and repeat. Move the cooked patties to the paper towel lined sheet, add the rest of the oil, and cook the remaining batch the same way.
7. Serve hot. Serve right away while the edges are crunchy, with sour cream, ranch dressing, or a fried egg on top.
How to Serve Mashed Potato Bacon Cakes
Serve the patties hot with a dollop of sour cream and a sprinkle of extra sliced scallions. For a brunch spread, pair them with muffin tin egg bites and a bowl of fresh fruit. At dinner they sit nicely next to roasted vegetables such as air fryer asparagus, or beside a crisp Italian house salad. For a bigger meal, stack a few next to a slice of tater tot sausage breakfast casserole.
How to Store and Reheat Mashed Potato Bacon Cakes
Cool leftover cakes to room temperature within two hours, then store them in an airtight container in the refrigerator for 3 to 4 days. Reheat on a baking sheet in a hot oven at 400 degrees F for 10 to 12 minutes, flipping once, until hot in the center and crisp again. A skillet over medium heat also works, while the microwave leaves the crust soft. For longer storage, freeze the shaped, uncooked patties on a tray, move them to a freezer bag, and cook from frozen for about 4 minutes per side, up to 2 months.
Tips and Variations for Mashed Potato Bacon Cakes
Chill the patties. Fifteen minutes in the refrigerator firms up the cheese and fat, which keeps the cakes from spreading when they hit the hot oil.
Keep the heat steady. Medium high is the target. If the oil smokes, lower the heat, because the panko darkens quickly and the center needs time to warm through.
Do not crowd the pan. Six patties fit in a large skillet with room to flip. Crowding drops the oil temperature and leaves greasy cakes.
Bake instead of fry. Place the coated patties on a lightly oiled sheet, spray the tops with cooking spray, and bake at 425 degrees F for about 25 minutes, flipping halfway.
Swap the cheese. Pepper Jack adds mild heat, Gouda adds a nutty flavor, and mozzarella gives the stretchiest center.
Add herbs. A tablespoon of chopped chives or parsley folded into the mixture brightens the richness.
Try a dipping sauce. Stir sour cream with a squeeze of lemon and a spoonful of chopped chives for a cool contrast to the hot cakes.
Season with care. Bacon and cheddar are already salty, so taste your leftover potatoes before adding any extra salt. For general guidance on storing leftovers, see this University of Wisconsin Extension article on leftovers food safety.
Frequently Asked Questions About Mashed Potato Bacon Cakes
Can I make mashed potato bacon cakes ahead of time?
Yes. Shape and coat the patties, cover them, and refrigerate for up to 24 hours, then fry just before serving. You can also freeze the uncooked patties for up to 2 months.
What potatoes work well for mashed potato bacon cakes?
Any variety works as long as the mash is cold and not too wet. Russet and Yukon Gold mashed with butter give the ideal texture, while very milky mash may need an extra spoonful of flour.
Why are my mashed potato bacon cakes falling apart?
The mixture is usually too warm or too wet. Chill the patties for 15 minutes, add a tablespoon more flour, and wait until the oil is hot before adding them. Flip only once the underside is deeply golden.
Can I use raw bacon in the mixture?
It is better to cook it first. Raw bacon will not finish cooking in the short time the patties spend in the pan, and pre cooked bacon stays crisp.
What can I serve alongside leftover potato patties?
Eggs, fresh salads, roasted vegetables, or a bowl of soup all pair nicely, and a simple dollop of sour cream is always welcome.
