Crispy Leftover Mashed Potato Pancakes

Honestly, I think I intentionally make way too many mashed potatoes on Sunday nights just so I can make these the next day. There is something downright magical about taking a Tupperware container of cold, stiff mashed potatoes and turning them into crispy, golden-brown comfort food.

Growing up, my mom would always whip up potato pancakes after Thanksgiving. The smell of butter sizzling in the cast-iron skillet would actually get me out of bed faster than the holiday itself! I usually serve these as a hearty breakfast side, but honestly, my kids will eat them for dinner with a dollop of sour cream and complain exactly zero times.

What You’ll Need (Ingredients)

You only need a few pantry staples to pull this together. The exact measurements depend on how many potatoes you have leftover, but here is my standard ratio for about 3 cups of potatoes:

• 3 cups cold mashed potatoes: (They must be cold! Warm potatoes will turn into mush in the pan).

• 1 large egg: This acts as our binder.

• 1/4 cup all-purpose flour: Helps hold everything together and creates that crispy crust.

• 1/2 cup shredded cheddar cheese: Because cheese makes everything better.

• 2 tablespoons fresh chives or green onions: Finely chopped.

• 1/2 teaspoon garlic powder: For a little extra savory kick.

• Salt and black pepper: To taste (remember your mashed potatoes are probably already seasoned, so go easy!).

• Butter and neutral oil (like canola or vegetable): For pan-frying.

Step-by-Step Method

1. Mix the Base

In a large mixing bowl, combine your cold mashed potatoes, egg, flour, shredded cheese, chives, garlic powder, salt, and pepper. I usually just get in there with clean hands to mix it thoroughly. If the mixture feels way too wet, add another tablespoon of flour.

2. Form the Patties

Scoop up about 1/3 cup of the potato mixture and roll it into a ball, then gently flatten it into a pancake shape. You want them to be about 1/2-inch thick.

3. Heat the Skillet

Place a heavy-bottomed skillet (cast iron is absolute best for this) over medium-high heat. Add a tablespoon of butter and a tablespoon of oil. Tip: Using a mix of oil and butter raises the smoke point so the butter doesn’t burn, but you still get that rich flavor!

4. Drain and Serve

Remove the crispy pancakes and place them briefly on a paper towel-lined plate to drain excess oil. Serve immediately while they are hot and crispy.

My Top Cooking Tips

• Use COLD Potatoes: I can’t stress this enough. If you try to use fresh, warm mashed potatoes, they will absorb too much flour, fall apart in the pan, and turn into an oily mess. Day-old fridge potatoes are perfect.

• Don’t Rush the Flip: The hardest part of this recipe is leaving them alone. If you try to flip them too early, they will break. Wait until you see a crispy brown edge forming along the bottom before you slide your spatula underneath.

• The Cast Iron Advantage: A well-seasoned cast-iron skillet will give you the crunchiest, most beautiful texture.

Serving Suggestions

Honestly, these are versatile enough to eat at any time of day! Here are my favorite ways to serve them:

• Classic Breakfast: Serve alongside fried eggs and crispy bacon. The runny egg yolk over the crispy potato is heaven.

• The “Pierogi” Style: Top with a generous dollop of sour cream and extra chopped chives.

• Sweet & Savory: This might sound crazy if you haven’t tried it, but dipping them in plain applesauce is a traditional and surprisingly delicious combo!

Frequently Asked Questions (FAQs)

1. Can I use freshly made mashed potatoes if I’m craving these right now?

Honestly, it’s risky. Warm mashed potatoes are too loose and will fall apart in the pan. If you absolutely must make them from scratch today, spread your freshly mashed potatoes into a thin layer on a baking sheet and pop them in the freezer for 30 minutes to chill them down fast before mixing your batter.

2. Why are my potato pancakes falling apart when I flip them?

This usually happens for one of two reasons: either your potato mixture was too wet (add a little more flour!), or you tried to flip them too soon. Let them get a really solid, crispy crust on the bottom before you even touch them with a spatula.

3. Can I freeze these?

Yes! I usually flash-freeze cooked and cooled pancakes on a baking sheet, then transfer them to a freezer bag. To reheat, just pop them in a toaster oven or air fryer at 200°C until they are heated through and crispy again.

4. What kind of oil is best for frying these?

I highly recommend using a 50/50 mix of butter and a neutral oil (like canola, vegetable, or avocado oil). The butter gives you that amazing flavor and beautiful browning, while the oil prevents the butter from burning in the hot pan.

5. Can I make them in the air fryer instead of pan-frying?

You can, but they won’t get quite as lacey and crispy as the ones in the photos. To air fry, spray both sides generously with cooking oil spray and cook at 200°C for about 12-15 minutes, flipping halfway through.
