Ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

Cold leftover mashed potatoes
All-purpose flour
Egg
Shredded cheese (cheddar, mozzarella, or a mix)
Green onions, chopped (optional)
Salt
Black pepper
Butter or oil (for frying)

Directions

In a large bowl, I combine the mashed potatoes, flour, egg, cheese, green onions, salt, and pepper. I mix until everything is fully incorporated. The mixture should be thick but scoopable.
I heat a nonstick skillet or cast iron pan over medium heat and add a tablespoon of butter or oil.
Using a spoon or scoop, I form the potato mixture into patties, about ½ inch thick.
I place the patties in the hot skillet, flattening slightly if needed, and cook for 3–4 minutes on each side until golden brown and crispy.
I transfer the cooked pancakes to a paper towel-lined plate and keep them warm while I finish the rest.
I serve them hot with sour cream, hot sauce, or a sprinkle of extra green onions.

Servings and timing

This recipe makes about 8–10 pancakes.
Prep time: 10 minutes
Cook time: 15 minutes
Total time: About 25 minutes

Variations

Sometimes I add leftover cooked veggies to the mix. I’ve also mixed in garlic powder or smoked paprika for extra flavor. If I want a gluten-free version, I substitute the flour with almond flour or a gluten-free flour blend, and it still turns out great.

storage/reheating

I store leftover pancakes in an airtight container in the fridge for up to 3 days. To reheat, I warm them in a skillet over medium heat or in the oven at 375°F until hot and crispy again—about 10 minutes. They also reheat nicely in the air fryer. I avoid the microwave if I want to keep the crisp texture.

FAQs

Can I use instant mashed potatoes?

Yes, I’ve used instant mashed potatoes as long as they’re chilled and thick. The consistency needs to be firm enough to form into patties.

What kind of cheese works best?

I usually go for cheddar because it melts well and adds great flavor, but I’ve also used mozzarella, gouda, or a sharp white cheddar with success.

Can I freeze mashed potato pancakes?

Yes, I let them cool completely, then freeze them in a single layer before transferring to a freezer bag. I reheat them in a skillet or air fryer for best results.

Why are my pancakes falling apart?

If the mixture is too loose, I add a little more flour or an extra egg to help bind it. Cold mashed potatoes also help them hold their shape better.

What’s the best dipping sauce?

Sour cream is my go-to, but I’ve also dipped them in spicy mayo, ranch, or even leftover gravy. They’re super versatile!
