Refrigerating: Once the salmon patties have cooled to room temperature, transfer them to an airtight container. They'll keep in the fridge for up to 3 days.
Freezing: Place the cooled patties on a baking sheet lined with parchment paper, ensuring they're not touching. Freeze for about 1-2 hours until firm. Once solid, transfer them to a freezer-safe bag or container, separating layers with parchment paper to prevent sticking. They can be stored in the freezer for up to 2 months.
Reheating: You can reheat refrigerated or thawed salmon patties in the air fryer at 370°F (185°C) for about 3-4 minutes or until they're hot and crisp again. If reheating from frozen, it might take a couple of minutes longer.
Tip: To maintain the best texture, it's advisable to reheat the patties in the air fryer rather than the microwave, as the air fryer will restore their crispy exterior.
