Basic Ingredients for Mashed Potato Pancakes

You only need a few pantry staples to get started:

• 2 cups leftover mashed potatoes (chilled)
• 1 large egg
• 1/2 cup shredded cheese (cheddar, mozzarella, or your favorite)
• 1/4 cup flour (all-purpose or gluten-free)
• 2 green onions, chopped (optional)
• Salt and pepper, to taste
• Butter or oil, for frying

These ingredients create a simple base, and from here you can get as creative as you like.

Step-by-Step Instructions

Step 1: Combine Ingredients

In a large bowl, combine the cold mashed potatoes, egg, shredded cheese, green onions, and flour. Mix until well combined. The dough should be thick and easy to form into patties. If it’s too wet, add a bit more flour.

Step 2: Shape the Pancakes

Scoop out 1/4-cup portions of the mixture and form into round, flat patties about 1/2 inch thick.

Step 3: Heat the Pan

Heat a skillet over medium heat and add a tablespoon of oil or butter. Swirl to coat the pan evenly.

Step 4: Cook Until Golden

Place the pancakes in the skillet and cook for 3–4 minutes per side, or until golden brown and crisp. Don’t overcrowd the pan—cook in batches if needed.

Step 5: Drain and Serve

Remove the pancakes and drain on paper towels. Serve warm with sour cream, applesauce, or your favorite toppings.

Flavor Variations to Try

Once you’ve mastered the basic recipe, you can easily customize it:

• Cheesy Bacon Pancakes: Add crumbled cooked bacon and extra cheese
• Spicy Jalapeño: Stir in chopped jalapeños and a pinch of cayenne
• Herb Lovers: Add chopped parsley, chives, dill, or thyme
• Garlic Parmesan: Use roasted garlic and shredded Parmesan cheese
• Southwest Style: Add corn, black beans, and taco seasoning

Tips for Success

• Cold mashed potatoes hold together better—don’t use freshly made ones
• Don’t flip too soon—let them crisp before turning
• Use a nonstick or cast-iron skillet for the best crust
• Test fry one pancake first to check seasoning and texture
• Keep warm in the oven while cooking the rest

What to Serve with Mashed Potato Pancakes

These pancakes are incredibly versatile. Pair them with:

• Eggs and bacon for breakfast
• A fresh green salad for a light lunch
• Roasted veggies or grilled sausage for dinner
• Applesauce or sour cream as dipping sauces

Can You Freeze Mashed Potato Pancakes?

Yes! They freeze beautifully:

• Cook and cool completely
• Place on a baking sheet to freeze individually
• Transfer to a freezer-safe bag or container
• Reheat in a toaster oven, skillet, or air fryer until hot and crispy

They’ll keep for up to 2 months.

Dietary Modifications

• Gluten-Free: Use gluten-free flour or oat flour
• Dairy-Free: Skip the cheese or use a plant-based alternative
• Vegan: Use a flax egg (1 tbsp ground flax + 3 tbsp water) and dairy-free cheese
• Low-Carb: Mix in mashed cauliflower to reduce carb count

Using Different Types of Mashed Potatoes

These pancakes work with almost any type of mashed potatoes:

• Buttery Yukon Golds: Super creamy and rich
• Garlic mashed: Adds bold flavor

• Mashed sweet potatoes: Make a sweeter, more unique version

Adjust the seasoning and flour based on moisture levels.

Storing and Reheating Leftovers

• Store in the fridge for up to 3 days
• Reheat in a skillet or air fryer to revive the crispy exterior
• Avoid microwaving—they’ll get soft and lose their crisp
