Recipe Background

Potato patties have roots in many cuisines — from Irish potato cakes to Eastern European potato fritters. The reason they work so well is simple:

Mashed potatoes already contain starch, which helps bind ingredients together. When combined with egg and lightly fried, they develop a crispy crust while staying creamy inside.

This recipe is especially popular after holidays when leftover mashed potatoes need a delicious makeover.

Ingredients

(Use ingredients in this order for best results.)

• 2 cups leftover mashed potatoes (cold works best)
• 1 large egg
• ¼ cup all-purpose flour (or breadcrumbs)
• ¼ cup shredded cheese (optional but recommended)
• 2 tablespoons chopped green onions or parsley
• ½ teaspoon salt (adjust based on your mashed potatoes)
• ½ teaspoon black pepper
• 2–3 tablespoons oil for frying

Ingredient Notes

• Cold mashed potatoes hold their shape better.
• Cheese adds richness and helps crisp the edges.
• Breadcrumbs can replace flour for extra crunch.
• Add garlic powder or paprika for more flavor.

Kitchen Tools Needed

• Mixing Bowl – Used to combine the mashed potatoes with egg, flour, and seasonings evenly. A medium bowl gives enough space for proper mixing.
• Fork or Spatula – Helps blend ingredients smoothly without overworking the potatoes.
• Measuring Cups & Spoons – Ensure accurate proportions so the patties hold together properly.
• Large Skillet or Frying Pan – Provides even heat distribution to create a golden, crispy crust. A non-stick or cast-iron skillet works best.
• Spatula – Essential for flipping the patties without breaking them.
• Paper Towels – Used to drain excess oil after frying.

Step-by-Step Instructions

1. Prepare the Mixture

In a mixing bowl, combine leftover mashed potatoes, egg, flour, cheese (if using), green onions, salt, and pepper. Mix until fully incorporated.

The mixture should be soft but firm enough to shape. If too sticky, add a little more flour.

2. Shape the Patties

Scoop about 2 tablespoons of mixture and shape into round, flat patties about ½ inch thick.

Place them on a plate while you prepare the pan.

3. Heat the Pan

Heat 2–3 tablespoons of oil in a large skillet over medium heat.

The oil should shimmer but not smoke. Medium heat ensures the patties cook evenly without burning.

4. Fry Until Golden

Place patties in the skillet without overcrowding. Cook for 3–4 minutes per side, or until golden brown and crispy.

Flip gently using a spatula.

5. Drain and Serve

Transfer cooked patties to a paper towel-lined plate to remove excess oil.

Serve warm for the best texture.

Pro Tips for Best Results

• Use cold mashed potatoes for easier shaping.
• Don’t overcrowd the pan — it lowers the temperature and reduces crispiness.
• Cook on medium heat to avoid burning the outside before the inside warms through.
• For extra crispiness, lightly coat patties in breadcrumbs before frying.

Variations & Substitutions

• Cheesy Upgrade: Add mozzarella or cheddar inside the patties.
• Spicy Version: Mix in chili flakes or diced jalapeños.
• Low-Carb Option: Replace flour with almond flour.
• Vegetable Boost: Add grated carrots or finely chopped spinach.
• Air Fryer Method: Cook at 375°F (190°C) for 10–12 minutes, flipping halfway.

What to Serve With Leftover Potato Patties

These pair beautifully with:

• Fried or poached eggs
• Sour cream or Greek yogurt
• Fresh salad
• Grilled chicken

• Steamed vegetables

They also make a great side dish for soups and stews.

Storage & Reheating Instructions

Refrigerator

• Oven: Bake at 350°F (175°C) for 8–10 minutes.
