Recipe Information
- Prep Time: 15 minutes
- Cook Time: 12 minutes
- Total Time: 27 minutes
- Servings: 6 patties
- Calories: Approximately 180 per patty
Ingredients
- 3 cups mashed potatoes (cold works best)
- 1 large egg
- 1 cup shredded mozzarella or cheddar cheese
- ¼ cup chopped green onions
- 2 tablespoons cornstarch or all-purpose flour (if needed)
- ½ teaspoon garlic powder
- Salt and black pepper, to taste
- 2 tablespoons vegetable oil or butter for frying
Instructions
Step 1: Mix the Ingredients
In a large bowl, combine:
- Mashed potatoes
- Egg
- Shredded cheese
- Green onions
- Garlic powder
- Salt and pepper
Mix until everything is evenly combined.
If the mixture feels too soft, stir in the cornstarch or flour.
Step 2: Shape the Patties
Divide the mixture into 6 equal portions.
Shape each portion into a thick round patty, about ½ inch thick.
Place them on a tray or plate.
Step 3: Chill (Optional)
For firmer patties, refrigerate them for 15–20 minutes before cooking.
Step 4: Pan-Fry
Heat the oil or butter in a non-stick skillet over medium heat.
Cook the patties for 4–5 minutes per side, until deeply golden brown and crispy.
Flip carefully using a wide spatula.
Step 5: Serve
Serve hot with:
- Sour cream
- Garlic aioli
- Ranch dressing
- Ketchup
- Chili sauce
Tips
- Cold mashed potatoes hold together much better than freshly made ones.
- Don’t overcrowd the pan—cook in batches if necessary.
- Flip only once for the crispiest crust.
- Freshly grated cheese melts better than pre-shredded cheese.
