Mashed potatoes: These are the base of the recipe, providing a creamy texture and rich flavor.

chopped green onions - Substitute with chopped chives: Chives offer a similar mild onion flavor and can be used in the same quantity.

How to Store / Freeze This Recipe
- Allow the potato cakes to cool completely before storing. This prevents condensation, which can make them soggy.
- Place the cooled potato cakes in an airtight container. If stacking, separate layers with parchment paper to avoid sticking.
- Store the container in the refrigerator for up to 3-4 days. Reheat in a skillet over medium heat until warmed through, or in an oven preheated to 350°F for about 10 minutes.
- For freezing, arrange the cooled potato cakes in a single layer on a baking sheet lined with parchment paper. Freeze until solid, about 1-2 hours.
- Once frozen, transfer the potato cakes to a freezer-safe bag or container. Label with the date and store for up to 2 months.
- To reheat from frozen, place the potato cakes on a baking sheet and bake in a preheated oven at 375°F for 15-20 minutes, or until heated through. Alternatively, reheat in a skillet over medium-low heat, covered, until warmed through.
How to Reheat Leftovers
- Preheat your oven to 350°F (175°C). Place the potato cakes on a baking sheet lined with parchment paper. Bake for about 10-15 minutes, or until heated through and crispy on the outside.
- Heat a skillet over medium heat and add a small amount of butter or olive oil. Place the potato cakes in the skillet and cook for 2-3 minutes on each side, until they are warmed through and have regained their crispy texture.
- For a quick option, use the microwave. Place the potato cakes on a microwave-safe plate and cover them with a damp paper towel. Microwave on medium power for 1-2 minutes, checking to ensure they are heated through.
- If you have an air fryer, preheat it to 350°F (175°C). Place the potato cakes in a single layer in the air fryer basket. Cook for 5-7 minutes, shaking the basket halfway through, until they are hot and crispy.
