Kitchen Equipment Needed
- Mixing bowl
- Large skillet or griddle
- Spatula
Ingredients Overview
- Mashed Potatoes: Leftover mashed potatoes that are already seasoned give the best flavor and texture.
- Cheese: Cheddar or mozzarella melts into a gooey center; feel free to try other melty cheeses for variation.
- Egg and Flour: Bind the mixture so the pancakes hold together while frying.
- Green Onions: Add a fresh, mild onion note.
Step-by-Step Instructions
1. Prepare the Batter
- In a mixing bowl, combine:
- 2 cups leftover mashed potatoes
- 1 egg
- 1/4 cup all-purpose flour (add more if needed to reach a moldable consistency)
- 1/2 cup shredded cheddar cheese
- 2 tablespoons chopped green onions
- Salt and pepper to taste
- Stir until the mixture is uniform and holds together when pressed into a ball. Adjust flour or a splash of milk as needed to achieve the right consistency.
2. Shape the Pancakes
- Scoop roughly 1/4 cup of the mixture and shape it into a patty about 1/2 inch thick. Repeat until the mixture is used.
3. Cook the Pancakes
- Heat 2–3 tablespoons of oil in a large skillet over medium heat.
- Place patties in the skillet without crowding them.
- Cook 3–4 minutes per side, or until each side is golden brown and crisp.
- Transfer to a paper towel-lined plate to drain excess oil.
4. Serve
- Serve hot with sour cream, applesauce, or your preferred dipping sauce.
Recipe Tips
- Consistency: If the mashed potatoes are too loose, add more flour. If too dry, mix in a splash of milk or another egg white.
- Cheese Variations: Parmesan, Gouda, Monterey Jack, or a blend can change the flavor profile.
- Make Ahead: Form patties and refrigerate for up to 24 hours before frying, or freeze for longer storage.
- Low-Oil Option: For a lighter version, cook on a lightly oiled baking sheet at 400°F (200°C) for 15–20 minutes, flipping halfway, until golden.
What to Serve With This Recipe
- Pair with eggs for a hearty breakfast.
- Serve alongside grilled chicken, steak, or roasted vegetables for a complete dinner.
- Enjoy as a snack with ranch dressing, marinara, or a herbed yogurt dip.
